DESCRIPTION

       You can query/set/replace/unset options with this command. The name is actually the
       section and the key separated by a dot, and the value will be escaped.

       Multiple lines can be added to an option by using the --add option. If you want to update
       or unset an option which can occur on multiple lines, a value-pattern (which is an
       extended regular expression, unless the --fixed-value option is given) needs to be given.
       Only the existing values that match the pattern are updated or unset. If you want to
       handle the lines that do not match the pattern, just prepend a single exclamation mark in
       front (see also the section called “EXAMPLES”), but note that this only works when the
       --fixed-value option is not in use.

       The --type=<type> option instructs git config to ensure that incoming and outgoing values
       are canonicalize-able under the given <type>. If no --type=<type> is given, no
       canonicalization will be performed. Callers may unset an existing --type specifier with
       --no-type.

       When reading, the values are read from the system, global and repository local
       configuration files by default, and options --system, --global, --local, --worktree and
       --file <filename> can be used to tell the command to read from only that location (see the
       section called “FILES”).

       When writing, the new value is written to the repository local configuration file by
       default, and options --system, --global, --worktree, --file <filename> can be used to tell
       the command to write to that location (you can say --local but that is the default).

       This command will fail with non-zero status upon error. Some exit codes are:

       •   The section or key is invalid (ret=1),

       •   no section or name was provided (ret=2),

       •   the config file is invalid (ret=3),

       •   the config file cannot be written (ret=4),

       •   you try to unset an option which does not exist (ret=5),

       •   you try to unset/set an option for which multiple lines match (ret=5), or

       •   you try to use an invalid regexp (ret=6).

       On success, the command returns the exit code 0.

       A list of all available configuration variables can be obtained using the git help
       --config command.

OPTIONS

       --replace-all
           Default behavior is to replace at most one line. This replaces all lines matching the
           key (and optionally the value-pattern).

       --add
           Adds a new line to the option without altering any existing values. This is the same
           as providing ^$ as the value-pattern in --replace-all.

       --comment <message>
           Append a comment at the end of new or modified lines.

               If _<message>_ begins with one or more whitespaces followed
               by "#", it is used as-is.  If it begins with "#", a space is
               prepended before it is used.  Otherwise, a string " # " (a
               space followed by a hash followed by a space) is prepended
               to it.  And the resulting string is placed immediately after
               the value defined for the variable.  The _<message>_ must
               not contain linefeed characters (no multi-line comments are
               permitted).

       --get
           Get the value for a given key (optionally filtered by a regex matching the value).
           Returns error code 1 if the key was not found and the last value if multiple key
           values were found.

       --get-all
           Like get, but returns all values for a multi-valued key.

       --get-regexp
           Like --get-all, but interprets the name as a regular expression and writes out the key
           names. Regular expression matching is currently case-sensitive and done against a
           canonicalized version of the key in which section and variable names are lowercased,
           but subsection names are not.

       --get-urlmatch <name> <URL>
           When given a two-part <name> as <section>.<key>, the value for <section>.<URL>.<key>
           whose <URL> part matches the best to the given URL is returned (if no such key exists,
           the value for <section>.<key> is used as a fallback). When given just the <section> as
           name, do so for all the keys in the section and list them. Returns error code 1 if no
           value is found.

       --global
           For writing options: write to global ~/.gitconfig file rather than the repository
           .git/config, write to $XDG_CONFIG_HOME/git/config file if this file exists and the
           ~/.gitconfig file doesn’t.

           For reading options: read only from global ~/.gitconfig and from
           $XDG_CONFIG_HOME/git/config rather than from all available files.

           See also the section called “FILES”.

       --system
           For writing options: write to system-wide $(prefix)/etc/gitconfig rather than the
           repository .git/config.

           For reading options: read only from system-wide $(prefix)/etc/gitconfig rather than
           from all available files.

           See also the section called “FILES”.

       --local
           For writing options: write to the repository .git/config file. This is the default
           behavior.

           For reading options: read only from the repository .git/config rather than from all
           available files.

           See also the section called “FILES”.

       --worktree
           Similar to --local except that $GIT_DIR/config.worktree is read from or written to if
           extensions.worktreeConfig is enabled. If not it’s the same as --local. Note that
           $GIT_DIR is equal to $GIT_COMMON_DIR for the main working tree, but is of the form
           $GIT_DIR/worktrees/<id>/ for other working trees. See git-worktree(1) to learn how to
           enable extensions.worktreeConfig.

       -f <config-file>, --file <config-file>
           For writing options: write to the specified file rather than the repository
           .git/config.

           For reading options: read only from the specified file rather than from all available
           files.

           See also the section called “FILES”.

       --blob <blob>
           Similar to --file but use the given blob instead of a file. E.g. you can use
           master:.gitmodules to read values from the file .gitmodules in the master branch. See
           "SPECIFYING REVISIONS" section in gitrevisions(7) for a more complete list of ways to
           spell blob names.

       --remove-section
           Remove the given section from the configuration file.

       --rename-section
           Rename the given section to a new name.

       --unset
           Remove the line matching the key from config file.

       --unset-all
           Remove all lines matching the key from config file.

       -l, --list
           List all variables set in config file, along with their values.

       --fixed-value
           When used with the value-pattern argument, treat value-pattern as an exact string
           instead of a regular expression. This will restrict the name/value pairs that are
           matched to only those where the value is exactly equal to the value-pattern.

       --type <type>
           git config will ensure that any input or output is valid under the given type
           constraint(s), and will canonicalize outgoing values in <type>'s canonical form.

           Valid <type>'s include:

           •   bool: canonicalize values as either "true" or "false".

           •   int: canonicalize values as simple decimal numbers. An optional suffix of k, m, or
               g will cause the value to be multiplied by 1024, 1048576, or 1073741824 upon
               input.

           •   bool-or-int: canonicalize according to either bool or int, as described above.

           •   path: canonicalize by expanding a leading ~ to the value of $HOME and ~user to the
               home directory for the specified user. This specifier has no effect when setting
               the value (but you can use git config section.variable ~/ from the command line to
               let your shell do the expansion.)

           •   expiry-date: canonicalize by converting from a fixed or relative date-string to a
               timestamp. This specifier has no effect when setting the value.

           •   color: When getting a value, canonicalize by converting to an ANSI color escape
               sequence. When setting a value, a sanity-check is performed to ensure that the
               given value is canonicalize-able as an ANSI color, but it is written as-is.

       --bool, --int, --bool-or-int, --path, --expiry-date
           Historical options for selecting a type specifier. Prefer instead --type (see above).

       --no-type
           Un-sets the previously set type specifier (if one was previously set). This option
           requests that git config not canonicalize the retrieved variable.  --no-type has no
           effect without --type=<type> or --<type>.

       -z, --null
           For all options that output values and/or keys, always end values with the null
           character (instead of a newline). Use newline instead as a delimiter between key and
           value. This allows for secure parsing of the output without getting confused e.g. by
           values that contain line breaks.

       --name-only
           Output only the names of config variables for --list or --get-regexp.

       --show-origin
           Augment the output of all queried config options with the origin type (file, standard
           input, blob, command line) and the actual origin (config file path, ref, or blob id if
           applicable).

       --show-scope
           Similar to --show-origin in that it augments the output of all queried config options
           with the scope of that value (worktree, local, global, system, command).

       --get-colorbool <name> [<stdout-is-tty>]
           Find the color setting for <name> (e.g.  color.diff) and output "true" or "false".
           <stdout-is-tty> should be either "true" or "false", and is taken into account when
           configuration says "auto". If <stdout-is-tty> is missing, then checks the standard
           output of the command itself, and exits with status 0 if color is to be used, or exits
           with status 1 otherwise. When the color setting for name is undefined, the command
           uses color.ui as fallback.

       --get-color <name> [<default>]
           Find the color configured for name (e.g.  color.diff.new) and output it as the ANSI
           color escape sequence to the standard output. The optional default parameter is used
           instead, if there is no color configured for name.

           --type=color [--default=<default>] is preferred over --get-color (but note that
           --get-color will omit the trailing newline printed by --type=color).

       -e, --edit
           Opens an editor to modify the specified config file; either --system, --global,
           --local (default), --worktree, or --file <config-file>.

       --[no-]includes
           Respect include.*  directives in config files when looking up values. Defaults to off
           when a specific file is given (e.g., using --file, --global, etc) and on when
           searching all config files.

       --default <value>
           When using --get, and the requested variable is not found, behave as if <value> were
           the value assigned to that variable.

CONFIGURATION

       pager.config is only respected when listing configuration, i.e., when using --list or any
       of the --get-* which may return multiple results. The default is to use a pager.

FILES

       By default, git config will read configuration options from multiple files:

       $(prefix)/etc/gitconfig
           System-wide configuration file.

       $XDG_CONFIG_HOME/git/config, ~/.gitconfig
           User-specific configuration files. When the XDG_CONFIG_HOME environment variable is
           not set or empty, $HOME/.config/ is used as $XDG_CONFIG_HOME.

           These are also called "global" configuration files. If both files exist, both files
           are read in the order given above.

       $GIT_DIR/config
           Repository specific configuration file.

       $GIT_DIR/config.worktree
           This is optional and is only searched when extensions.worktreeConfig is present in
           $GIT_DIR/config.

       You may also provide additional configuration parameters when running any git command by
       using the -c option. See git(1) for details.

       Options will be read from all of these files that are available. If the global or the
       system-wide configuration files are missing or unreadable they will be ignored. If the
       repository configuration file is missing or unreadable, git config will exit with a
       non-zero error code. An error message is produced if the file is unreadable, but not if it
       is missing.

       The files are read in the order given above, with last value found taking precedence over
       values read earlier. When multiple values are taken then all values of a key from all
       files will be used.

       By default, options are only written to the repository specific configuration file. Note
       that this also affects options like --replace-all and --unset. git config will only ever
       change one file at a time.

       You can limit which configuration sources are read from or written to by specifying the
       path of a file with the --file option, or by specifying a configuration scope with
       --system, --global, --local, or --worktree. For more, see the section called “OPTIONS”
       above.

SCOPES

       Each configuration source falls within a configuration scope. The scopes are:

       system
           $(prefix)/etc/gitconfig

       global
           $XDG_CONFIG_HOME/git/config

           ~/.gitconfig

       local
           $GIT_DIR/config

       worktree
           $GIT_DIR/config.worktree

       command
           GIT_CONFIG_{COUNT,KEY,VALUE} environment variables (see the section called
           “ENVIRONMENT” below)

           the -c option

       With the exception of command, each scope corresponds to a command line option: --system,
       --global, --local, --worktree.

       When reading options, specifying a scope will only read options from the files within that
       scope. When writing options, specifying a scope will write to the files within that scope
       (instead of the repository specific configuration file). See the section called “OPTIONS”
       above for a complete description.

       Most configuration options are respected regardless of the scope it is defined in, but
       some options are only respected in certain scopes. See the respective option’s
       documentation for the full details.

   Protected configuration
       Protected configuration refers to the system, global, and command scopes. For security
       reasons, certain options are only respected when they are specified in protected
       configuration, and ignored otherwise.

       Git treats these scopes as if they are controlled by the user or a trusted administrator.
       This is because an attacker who controls these scopes can do substantial harm without
       using Git, so it is assumed that the user’s environment protects these scopes against
       attackers.

ENVIRONMENT

       GIT_CONFIG_GLOBAL, GIT_CONFIG_SYSTEM
           Take the configuration from the given files instead from global or system-level
           configuration. See git(1) for details.

       GIT_CONFIG_NOSYSTEM
           Whether to skip reading settings from the system-wide $(prefix)/etc/gitconfig file.
           See git(1) for details.

       See also the section called “FILES”.

       GIT_CONFIG_COUNT, GIT_CONFIG_KEY_<n>, GIT_CONFIG_VALUE_<n>
           If GIT_CONFIG_COUNT is set to a positive number, all environment pairs
           GIT_CONFIG_KEY_<n> and GIT_CONFIG_VALUE_<n> up to that number will be added to the
           process’s runtime configuration. The config pairs are zero-indexed. Any missing key or
           value is treated as an error. An empty GIT_CONFIG_COUNT is treated the same as
           GIT_CONFIG_COUNT=0, namely no pairs are processed. These environment variables will
           override values in configuration files, but will be overridden by any explicit options
           passed via git -c.

           This is useful for cases where you want to spawn multiple git commands with a common
           configuration but cannot depend on a configuration file, for example when writing
           scripts.

       GIT_CONFIG
           If no --file option is provided to git config, use the file given by GIT_CONFIG as if
           it were provided via --file. This variable has no effect on other Git commands, and is
           mostly for historical compatibility; there is generally no reason to use it instead of
           the --file option.

EXAMPLES

       Given a .git/config like this:

           #
           # This is the config file, and
           # a '#' or ';' character indicates
           # a comment
           #

           ; core variables
           [core]
                   ; Don't trust file modes
                   filemode = false

           ; Our diff algorithm
           [diff]
                   external = /usr/local/bin/diff-wrapper
                   renames = true

           ; Proxy settings
           [core]
                   gitproxy=proxy-command for kernel.org
                   gitproxy=default-proxy ; for all the rest

           ; HTTP
           [http]
                   sslVerify
           [http "https://weak.example.com"]
                   sslVerify = false
                   cookieFile = /tmp/cookie.txt

       you can set the filemode to true with

           % git config core.filemode true

       The hypothetical proxy command entries actually have a postfix to discern what URL they
       apply to. Here is how to change the entry for kernel.org to "ssh".

           % git config core.gitproxy '"ssh" for kernel.org' 'for kernel.org$'

       This makes sure that only the key/value pair for kernel.org is replaced.

       To delete the entry for renames, do

           % git config --unset diff.renames

       If you want to delete an entry for a multivar (like core.gitproxy above), you have to
       provide a regex matching the value of exactly one line.

       To query the value for a given key, do

           % git config --get core.filemode

       or

           % git config core.filemode

       or, to query a multivar:

           % git config --get core.gitproxy "for kernel.org$"

       If you want to know all the values for a multivar, do:

           % git config --get-all core.gitproxy

       If you like to live dangerously, you can replace all core.gitproxy by a new one with

           % git config --replace-all core.gitproxy ssh

       However, if you really only want to replace the line for the default proxy, i.e. the one
       without a "for ..." postfix, do something like this:

           % git config core.gitproxy ssh '! for '

       To actually match only values with an exclamation mark, you have to

           % git config section.key value '[!]'

       To add a new proxy, without altering any of the existing ones, use

           % git config --add core.gitproxy '"proxy-command" for example.com'

       An example to use customized color from the configuration in your script:

           #!/bin/sh
           WS=$(git config --get-color color.diff.whitespace "blue reverse")
           RESET=$(git config --get-color "" "reset")
           echo "${WS}your whitespace color or blue reverse${RESET}"

       For URLs in https://weak.example.com, http.sslVerify is set to false, while it is set to
       true for all others:

           % git config --type=bool --get-urlmatch http.sslverify https://good.example.com
           true
           % git config --type=bool --get-urlmatch http.sslverify https://weak.example.com

CONFIGURATION FILE

       The Git configuration file contains a number of variables that affect the Git commands'
       behavior. The files .git/config and optionally config.worktree (see the "CONFIGURATION
       FILE" section of git-worktree(1)) in each repository are used to store the configuration
       for that repository, and $HOME/.gitconfig is used to store a per-user configuration as
       fallback values for the .git/config file. The file /etc/gitconfig can be used to store a
       system-wide default configuration.

       The configuration variables are used by both the Git plumbing and the porcelain commands.
       The variables are divided into sections, wherein the fully qualified variable name of the
       variable itself is the last dot-separated segment and the section name is everything
       before the last dot. The variable names are case-insensitive, allow only alphanumeric
       characters and -, and must start with an alphabetic character. Some variables may appear
       multiple times; we say then that the variable is multivalued.

   Syntax
       The syntax is fairly flexible and permissive. Whitespace characters, which in this context
       are the space character (SP) and the horizontal tabulation (HT), are mostly ignored. The #
       and ; characters begin comments to the end of line. Blank lines are ignored.

       The file consists of sections and variables. A section begins with the name of the section
       in square brackets and continues until the next section begins. Section names are
       case-insensitive. Only alphanumeric characters, - and . are allowed in section names. Each
       variable must belong to some section, which means that there must be a section header
       before the first setting of a variable.

       Sections can be further divided into subsections. To begin a subsection put its name in
       double quotes, separated by space from the section name, in the section header, like in
       the example below:

                   [section "subsection"]

       Subsection names are case sensitive and can contain any characters except newline and the
       null byte. Doublequote " and backslash can be included by escaping them as \" and \\,
       respectively. Backslashes preceding other characters are dropped when reading; for
       example, \t is read as t and \0 is read as 0. Section headers cannot span multiple lines.
       Variables may belong directly to a section or to a given subsection. You can have
       [section] if you have [section "subsection"], but you don’t need to.

       There is also a deprecated [section.subsection] syntax. With this syntax, the subsection
       name is converted to lower-case and is also compared case sensitively. These subsection
       names follow the same restrictions as section names.

       All the other lines (and the remainder of the line after the section header) are
       recognized as setting variables, in the form name = value (or just name, which is a
       short-hand to say that the variable is the boolean "true"). The variable names are
       case-insensitive, allow only alphanumeric characters and -, and must start with an
       alphabetic character.

       Whitespace characters surrounding name, = and value are discarded. Internal whitespace
       characters within value are retained verbatim. Comments starting with either # or ; and
       extending to the end of line are discarded. A line that defines a value can be continued
       to the next line by ending it with a backslash (\); the backslash and the end-of-line
       characters are discarded.

       If value needs to contain leading or trailing whitespace characters, it must be enclosed
       in double quotation marks ("). Inside double quotation marks, double quote (") and
       backslash (\) characters must be escaped: use \" for " and \\ for \.

       The following escape sequences (beside \" and \\) are recognized: \n for newline character
       (NL), \t for horizontal tabulation (HT, TAB) and \b for backspace (BS). Other char escape
       sequences (including octal escape sequences) are invalid.

   Includes
       The include and includeIf sections allow you to include config directives from another
       source. These sections behave identically to each other with the exception that includeIf
       sections may be ignored if their condition does not evaluate to true; see "Conditional
       includes" below.

       You can include a config file from another by setting the special include.path (or
       includeIf.*.path) variable to the name of the file to be included. The variable takes a
       pathname as its value, and is subject to tilde expansion. These variables can be given
       multiple times.

       The contents of the included file are inserted immediately, as if they had been found at
       the location of the include directive. If the value of the variable is a relative path,
       the path is considered to be relative to the configuration file in which the include
       directive was found. See below for examples.

   Conditional includes
       You can conditionally include a config file from another by setting an
       includeIf.<condition>.path variable to the name of the file to be included.

       The condition starts with a keyword followed by a colon and some data whose format and
       meaning depends on the keyword. Supported keywords are:

       gitdir
           The data that follows the keyword gitdir: is used as a glob pattern. If the location
           of the .git directory matches the pattern, the include condition is met.

           The .git location may be auto-discovered, or come from $GIT_DIR environment variable.
           If the repository is auto-discovered via a .git file (e.g. from submodules, or a
           linked worktree), the .git location would be the final location where the .git
           directory is, not where the .git file is.

           The pattern can contain standard globbing wildcards and two additional ones, **/ and
           /**, that can match multiple path components. Please refer to gitignore(5) for
           details. For convenience:

           •   If the pattern starts with ~/, ~ will be substituted with the content of the
               environment variable HOME.

           •   If the pattern starts with ./, it is replaced with the directory containing the
               current config file.

           •   If the pattern does not start with either ~/, ./ or /, **/ will be automatically
               prepended. For example, the pattern foo/bar becomes **/foo/bar and would match
               /any/path/to/foo/bar.

           •   If the pattern ends with /, ** will be automatically added. For example, the
               pattern foo/ becomes foo/**. In other words, it matches "foo" and everything
               inside, recursively.

       gitdir/i
           This is the same as gitdir except that matching is done case-insensitively (e.g. on
           case-insensitive file systems)

       onbranch
           The data that follows the keyword onbranch: is taken to be a pattern with standard
           globbing wildcards and two additional ones, **/ and /**, that can match multiple path
           components. If we are in a worktree where the name of the branch that is currently
           checked out matches the pattern, the include condition is met.

           If the pattern ends with /, ** will be automatically added. For example, the pattern
           foo/ becomes foo/**. In other words, it matches all branches that begin with foo/.
           This is useful if your branches are organized hierarchically and you would like to
           apply a configuration to all the branches in that hierarchy.

       hasconfig:remote.*.url:
           The data that follows this keyword is taken to be a pattern with standard globbing
           wildcards and two additional ones, **/ and /**, that can match multiple components.
           The first time this keyword is seen, the rest of the config files will be scanned for
           remote URLs (without applying any values). If there exists at least one remote URL
           that matches this pattern, the include condition is met.

           Files included by this option (directly or indirectly) are not allowed to contain
           remote URLs.

           Note that unlike other includeIf conditions, resolving this condition relies on
           information that is not yet known at the point of reading the condition. A typical use
           case is this option being present as a system-level or global-level config, and the
           remote URL being in a local-level config; hence the need to scan ahead when resolving
           this condition. In order to avoid the chicken-and-egg problem in which
           potentially-included files can affect whether such files are potentially included, Git
           breaks the cycle by prohibiting these files from affecting the resolution of these
           conditions (thus, prohibiting them from declaring remote URLs).

           As for the naming of this keyword, it is for forwards compatibility with a naming
           scheme that supports more variable-based include conditions, but currently Git only
           supports the exact keyword described above.

       A few more notes on matching via gitdir and gitdir/i:

       •   Symlinks in $GIT_DIR are not resolved before matching.

       •   Both the symlink & realpath versions of paths will be matched outside of $GIT_DIR.
           E.g. if ~/git is a symlink to /mnt/storage/git, both gitdir:~/git and
           gitdir:/mnt/storage/git will match.

           This was not the case in the initial release of this feature in v2.13.0, which only
           matched the realpath version. Configuration that wants to be compatible with the
           initial release of this feature needs to either specify only the realpath version, or
           both versions.

       •   Note that "../" is not special and will match literally, which is unlikely what you
           want.

                   path = ~/foo.inc ; find "foo.inc" in your `$HOME` directory

           ; include if $GIT_DIR is /path/to/foo/.git
           [includeIf "gitdir:/path/to/foo/.git"]
                   path = /path/to/foo.inc

           ; relative paths are always relative to the including
           ; file (if the condition is true); their location is not
           ; affected by the condition

                   path = foo.inc

                   path = foo.inc

           ; include only if a remote with the given URL exists (note
           ; that such a URL may be provided later in a file or in a
           ; file read after this file is read, as seen in this example)
           [includeIf "hasconfig:remote.*.url:https://example.com/**"]
                   path = foo.inc
           [remote "origin"]
                   url = https://example.com/git

   Values
       Values of many variables are treated as a simple string, but there are variables that take
       values of specific types and there are rules as to how to spell them.

       boolean
           When a variable is said to take a boolean value, many synonyms are accepted for true
           and false; these are all case-insensitive.

           true
               Boolean true literals are yes, on, true, and 1. Also, a variable defined without =
               <value> is taken as true.

           false
               Boolean false literals are no, off, false, 0 and the empty string.

               When converting a value to its canonical form using the --type=bool type
               specifier, git config will ensure that the output is "true" or "false" (spelled in
               lowercase).

       integer
           The value for many variables that specify various sizes can be suffixed with k, M,...
           to mean "scale the number by 1024", "by 1024x1024", etc.

       color
           The value for a variable that takes a color is a list of colors (at most two, one for
           foreground and one for background) and attributes (as many as you want), separated by
           spaces.

           The basic colors accepted are normal, black, red, green, yellow, blue, magenta, cyan,
           white and default. The first color given is the foreground; the second is the
           background. All the basic colors except normal and default have a bright variant that
           can be specified by prefixing the color with bright, like brightred.

           The color normal makes no change to the color. It is the same as an empty string, but
           can be used as the foreground color when specifying a background color alone (for
           example, "normal red").

           The color default explicitly resets the color to the terminal default, for example to
           specify a cleared background. Although it varies between terminals, this is usually
           not the same as setting to "white black".

           Colors may also be given as numbers between 0 and 255; these use ANSI 256-color mode
           (but note that not all terminals may support this). If your terminal supports it, you
           may also specify 24-bit RGB values as hex, like #ff0ab3.

           The accepted attributes are bold, dim, ul, blink, reverse, italic, and strike (for
           crossed-out or "strikethrough" letters). The position of any attributes with respect
           to the colors (before, after, or in between), doesn’t matter. Specific attributes may
           be turned off by prefixing them with no or no- (e.g., noreverse, no-ul, etc).

           The pseudo-attribute reset resets all colors and attributes before applying the
           specified coloring. For example, reset green will result in a green foreground and
           default background without any active attributes.

           An empty color string produces no color effect at all. This can be used to avoid
           coloring specific elements without disabling color entirely.

           For git’s pre-defined color slots, the attributes are meant to be reset at the
           beginning of each item in the colored output. So setting color.decorate.branch to
           black will paint that branch name in a plain black, even if the previous thing on the
           same output line (e.g. opening parenthesis before the list of branch names in log
           --decorate output) is set to be painted with bold or some other attribute. However,
           custom log formats may do more complicated and layered coloring, and the negated forms
           may be useful there.

       pathname
           A variable that takes a pathname value can be given a string that begins with "~/" or
           "~user/", and the usual tilde expansion happens to such a string: ~/ is expanded to
           the value of $HOME, and ~user/ to the specified user’s home directory.

           If a path starts with %(prefix)/, the remainder is interpreted as a path relative to
           Git’s "runtime prefix", i.e. relative to the location where Git itself was installed.
           For example, %(prefix)/bin/ refers to the directory in which the Git executable itself
           lives. If Git was compiled without runtime prefix support, the compiled-in prefix will
           be substituted instead. In the unlikely event that a literal path needs to be
           specified that should not be expanded, it needs to be prefixed by ./, like so:
           ./%(prefix)/bin.

   Variables
       Note that this list is non-comprehensive and not necessarily complete. For
       command-specific variables, you will find a more detailed description in the appropriate
       manual page.

       Other git-related tools may and do use their own variables. When inventing new variables
       for use in your own tool, make sure their names do not conflict with those that are used
       by Git itself and other popular tools, and describe them in your documentation.

       add.ignoreErrors, add.ignore-errors (deprecated)
           Tells git add to continue adding files when some files cannot be added due to indexing
           errors. Equivalent to the --ignore-errors option of git-add(1).  add.ignore-errors is
           deprecated, as it does not follow the usual naming convention for configuration
           variables.

       add.interactive.useBuiltin
           Unused configuration variable. Used in Git versions v2.25.0 to v2.36.0 to enable the
           built-in version of git-add(1)'s interactive mode, which then became the default in
           Git versions v2.37.0 to v2.39.0.

       advice.*
           These variables control various optional help messages designed to aid new users. When
           left unconfigured, Git will give the message alongside instructions on how to squelch
           it. You can tell Git that you do not need the help message by setting these to false:

           addEmbeddedRepo
               Shown when the user accidentally adds one git repo inside of another.

           addEmptyPathspec
               Shown when the user runs git add without providing the pathspec parameter.

           addIgnoredFile
               Shown when the user attempts to add an ignored file to the index.

           amWorkDir
               Shown when git-am(1) fails to apply a patch file, to tell the user the location of
               the file.

           ambiguousFetchRefspec
               Shown when a fetch refspec for multiple remotes maps to the same remote-tracking
               branch namespace and causes branch tracking set-up to fail.

           checkoutAmbiguousRemoteBranchName
               Shown when the argument to git-checkout(1) and git-switch(1) ambiguously resolves
               to a remote tracking branch on more than one remote in situations where an
               unambiguous argument would have otherwise caused a remote-tracking branch to be
               checked out. See the checkout.defaultRemote configuration variable for how to set
               a given remote to be used by default in some situations where this advice would be
               printed.

           commitBeforeMerge
               Shown when git-merge(1) refuses to merge to avoid overwriting local changes.

           detachedHead
               Shown when the user uses git-switch(1) or git-checkout(1) to move to the detached
               HEAD state, to tell the user how to create a local branch after the fact.

           diverging
               Shown when a fast-forward is not possible.

           fetchShowForcedUpdates
               Shown when git-fetch(1) takes a long time to calculate forced updates after ref
               updates, or to warn that the check is disabled.

           forceDeleteBranch
               Shown when the user tries to delete a not fully merged branch without the force
               option set.

           ignoredHook
               Shown when a hook is ignored because the hook is not set as executable.

           implicitIdentity
               Shown when the user’s information is guessed from the system username and domain
               name, to tell the user how to set their identity configuration.

           mergeConflict
               Shown when various commands stop because of conflicts.

           nestedTag
               Shown when a user attempts to recursively tag a tag object.

           pushAlreadyExists
               Shown when git-push(1) rejects an update that does not qualify for fast-forwarding
               (e.g., a tag.)

           pushFetchFirst
               Shown when git-push(1) rejects an update that tries to overwrite a remote ref that
               points at an object we do not have.

           pushNeedsForce
               Shown when git-push(1) rejects an update that tries to overwrite a remote ref that
               points at an object that is not a commit-ish, or make the remote ref point at an
               object that is not a commit-ish.

           pushNonFFCurrent
               Shown when git-push(1) fails due to a non-fast-forward update to the current
               branch.

           pushNonFFMatching
               Shown when the user ran git-push(1) and pushed "matching refs" explicitly (i.e.
               used :, or specified a refspec that isn’t the current branch) and it resulted in a
               non-fast-forward error.

           pushRefNeedsUpdate
               Shown when git-push(1) rejects a forced update of a branch when its
               remote-tracking ref has updates that we do not have locally.

           pushUnqualifiedRefname
               Shown when git-push(1) gives up trying to guess based on the source and
               destination refs what remote ref namespace the source belongs in, but where we can
               still suggest that the user push to either refs/heads/* or refs/tags/* based on
               the type of the source object.

           pushUpdateRejected
               Set this variable to false if you want to disable pushNonFFCurrent,
               pushNonFFMatching, pushAlreadyExists, pushFetchFirst, pushNeedsForce, and
               pushRefNeedsUpdate simultaneously.

           refSyntax
               Shown when the user provides an illegal ref name, to tell the user about the ref
               syntax documentation.

           resetNoRefresh
               Shown when git-reset(1) takes more than 2 seconds to refresh the index after
               reset, to tell the user that they can use the --no-refresh option.

           resolveConflict
               Shown by various commands when conflicts prevent the operation from being
               performed.

           rmHints
               Shown on failure in the output of git-rm(1), to give directions on how to proceed
               from the current state.

           sequencerInUse
               Shown when a sequencer command is already in progress.

           skippedCherryPicks
               Shown when git-rebase(1) skips a commit that has already been cherry-picked onto
               the upstream branch.

           statusAheadBehind
               Shown when git-status(1) computes the ahead/behind counts for a local ref compared
               to its remote tracking ref, and that calculation takes longer than expected. Will
               not appear if status.aheadBehind is false or the option --no-ahead-behind is
               given.

           statusHints
               Show directions on how to proceed from the current state in the output of git-
               status(1), in the template shown when writing commit messages in git-commit(1),
               and in the help message shown by git-switch(1) or git-checkout(1) when switching
               branches.

           statusUoption
               Shown when git-status(1) takes more than 2 seconds to enumerate untracked files,
               to tell the user that they can use the -u option.

           submoduleAlternateErrorStrategyDie
               Shown when a submodule.alternateErrorStrategy option configured to "die" causes a
               fatal error.

           submoduleMergeConflict
               Advice shown when a non-trivial submodule merge conflict is encountered.

           submodulesNotUpdated
               Shown when a user runs a submodule command that fails because git submodule update
               --init was not run.

           suggestDetachingHead
               Shown when git-switch(1) refuses to detach HEAD without the explicit --detach
               option.

           updateSparsePath
               Shown when either git-add(1) or git-rm(1) is asked to update index entries outside
               the current sparse checkout.

           waitingForEditor
               Shown when Git is waiting for editor input. Relevant when e.g. the editor is not
               launched inside the terminal.

           worktreeAddOrphan
               Shown when the user tries to create a worktree from an invalid reference, to tell
               the user how to create a new unborn branch instead.

       alias.*
           Command aliases for the git(1) command wrapper - e.g. after defining alias.last =
           cat-file commit HEAD, the invocation git last is equivalent to git cat-file commit
           HEAD. To avoid confusion and troubles with script usage, aliases that hide existing
           Git commands are ignored. Arguments are split by spaces, the usual shell quoting and
           escaping are supported. A quote pair or a backslash can be used to quote them.

           Note that the first word of an alias does not necessarily have to be a command. It can
           be a command-line option that will be passed into the invocation of git. In
           particular, this is useful when used with -c to pass in one-time configurations or -p
           to force pagination. For example, loud-rebase = -c commit.verbose=true rebase can be
           defined such that running git loud-rebase would be equivalent to git -c
           commit.verbose=true rebase. Also, ps = -p status would be a helpful alias since git ps
           would paginate the output of git status where the original command does not.

           If the alias expansion is prefixed with an exclamation point, it will be treated as a
           shell command. For example, defining alias.new = !gitk --all --not ORIG_HEAD, the
           invocation git new is equivalent to running the shell command gitk --all --not
           ORIG_HEAD. Note that shell commands will be executed from the top-level directory of a
           repository, which may not necessarily be the current directory.  GIT_PREFIX is set as
           returned by running git rev-parse --show-prefix from the original current directory.
           See git-rev-parse(1).

       am.keepcr
           If true, git-am will call git-mailsplit for patches in mbox format with parameter
           --keep-cr. In this case git-mailsplit will not remove \r from lines ending with \r\n.
           Can be overridden by giving --no-keep-cr from the command line. See git-am(1), git-
           mailsplit(1).

       am.threeWay
           By default, git am will fail if the patch does not apply cleanly. When set to true,
           this setting tells git am to fall back on 3-way merge if the patch records the
           identity of blobs it is supposed to apply to and we have those blobs available locally
           (equivalent to giving the --3way option from the command line). Defaults to false. See
           git-am(1).

       apply.ignoreWhitespace
           When set to change, tells git apply to ignore changes in whitespace, in the same way
           as the --ignore-space-change option. When set to one of: no, none, never, false, it
           tells git apply to respect all whitespace differences. See git-apply(1).

       apply.whitespace
           Tells git apply how to handle whitespace, in the same way as the --whitespace option.
           See git-apply(1).

       attr.tree
           A reference to a tree in the repository from which to read attributes, instead of the
           .gitattributes file in the working tree. In a bare repository, this defaults to
           HEAD:.gitattributes. If the value does not resolve to a valid tree object, an empty
           tree is used instead. When the GIT_ATTR_SOURCE environment variable or --attr-source
           command line option are used, this configuration variable has no effect.

       blame.blankBoundary
           Show blank commit object name for boundary commits in git-blame(1). This option
           defaults to false.

       blame.coloring
           This determines the coloring scheme to be applied to blame output. It can be
           repeatedLines, highlightRecent, or none which is the default.

       blame.date
           Specifies the format used to output dates in git-blame(1). If unset the iso format is
           used. For supported values, see the discussion of the --date option at git-log(1).

       blame.showEmail
           Show the author email instead of author name in git-blame(1). This option defaults to
           false.

       blame.showRoot
           Do not treat root commits as boundaries in git-blame(1). This option defaults to
           false.

       blame.ignoreRevsFile
           Ignore revisions listed in the file, one unabbreviated object name per line, in git-
           blame(1). Whitespace and comments beginning with # are ignored. This option may be
           repeated multiple times. Empty file names will reset the list of ignored revisions.
           This option will be handled before the command line option --ignore-revs-file.

       blame.markUnblamableLines
           Mark lines that were changed by an ignored revision that we could not attribute to
           another commit with a * in the output of git-blame(1).

       blame.markIgnoredLines
           Mark lines that were changed by an ignored revision that we attributed to another
           commit with a ?  in the output of git-blame(1).

       branch.autoSetupMerge
           Tells git branch, git switch and git checkout to set up new branches so that git-
           pull(1) will appropriately merge from the starting point branch. Note that even if
           this option is not set, this behavior can be chosen per-branch using the --track and
           --no-track options. The valid settings are: false — no automatic setup is done; true —
           automatic setup is done when the starting point is a remote-tracking branch; always —
           automatic setup is done when the starting point is either a local branch or
           remote-tracking branch; inherit — if the starting point has a tracking configuration,
           it is copied to the new branch; simple — automatic setup is done only when the
           starting point is a remote-tracking branch and the new branch has the same name as the
           remote branch. This option defaults to true.

       branch.autoSetupRebase
           When a new branch is created with git branch, git switch or git checkout that tracks
           another branch, this variable tells Git to set up pull to rebase instead of merge (see
           "branch.<name>.rebase"). When never, rebase is never automatically set to true. When
           local, rebase is set to true for tracked branches of other local branches. When
           remote, rebase is set to true for tracked branches of remote-tracking branches. When
           always, rebase will be set to true for all tracking branches. See
           "branch.autoSetupMerge" for details on how to set up a branch to track another branch.
           This option defaults to never.

       branch.sort
           This variable controls the sort ordering of branches when displayed by git-branch(1).
           Without the "--sort=<value>" option provided, the value of this variable will be used
           as the default. See git-for-each-ref(1) field names for valid values.

       branch.<name>.remote
           When on branch <name>, it tells git fetch and git push which remote to fetch from or
           push to. The remote to push to may be overridden with remote.pushDefault (for all
           branches). The remote to push to, for the current branch, may be further overridden by
           branch.<name>.pushRemote. If no remote is configured, or if you are not on any branch
           and there is more than one remote defined in the repository, it defaults to origin for
           fetching and remote.pushDefault for pushing. Additionally, .  (a period) is the
           current local repository (a dot-repository), see branch.<name>.merge's final note
           below.

       branch.<name>.pushRemote
           When on branch <name>, it overrides branch.<name>.remote for pushing. It also
           overrides remote.pushDefault for pushing from branch <name>. When you pull from one
           place (e.g. your upstream) and push to another place (e.g. your own publishing
           repository), you would want to set remote.pushDefault to specify the remote to push to
           for all branches, and use this option to override it for a specific branch.

       branch.<name>.merge
           Defines, together with branch.<name>.remote, the upstream branch for the given branch.
           It tells git fetch/git pull/git rebase which branch to merge and can also affect git
           push (see push.default). When in branch <name>, it tells git fetch the default refspec
           to be marked for merging in FETCH_HEAD. The value is handled like the remote part of a
           refspec, and must match a ref which is fetched from the remote given by
           "branch.<name>.remote". The merge information is used by git pull (which first calls
           git fetch) to lookup the default branch for merging. Without this option, git pull
           defaults to merge the first refspec fetched. Specify multiple values to get an octopus
           merge. If you wish to setup git pull so that it merges into <name> from another branch
           in the local repository, you can point branch.<name>.merge to the desired branch, and
           use the relative path setting .  (a period) for branch.<name>.remote.

       branch.<name>.mergeOptions
           Sets default options for merging into branch <name>. The syntax and supported options
           are the same as those of git-merge(1), but option values containing whitespace
           characters are currently not supported.

       branch.<name>.rebase
           When true, rebase the branch <name> on top of the fetched branch, instead of merging
           the default branch from the default remote when "git pull" is run. See "pull.rebase"
           for doing this in a non branch-specific manner.

           When merges (or just m), pass the --rebase-merges option to git rebase so that the
           local merge commits are included in the rebase (see git-rebase(1) for details).

           When the value is interactive (or just i), the rebase is run in interactive mode.

           NOTE: this is a possibly dangerous operation; do not use it unless you understand the
           implications (see git-rebase(1) for details).

       branch.<name>.description
           Branch description, can be edited with git branch --edit-description. Branch
           description is automatically added to the format-patch cover letter or request-pull
           summary.

       browser.<tool>.cmd
           Specify the command to invoke the specified browser. The specified command is
           evaluated in shell with the URLs passed as arguments. (See git-web--browse(1).)

       browser.<tool>.path
           Override the path for the given tool that may be used to browse HTML help (see -w
           option in git-help(1)) or a working repository in gitweb (see git-instaweb(1)).

       bundle.*
           The bundle.*  keys may appear in a bundle list file found via the git clone
           --bundle-uri option. These keys currently have no effect if placed in a repository
           config file, though this will change in the future. See the bundle URI design
           document[1] for more details.

       bundle.version
           This integer value advertises the version of the bundle list format used by the bundle
           list. Currently, the only accepted value is 1.

       bundle.mode
           This string value should be either all or any. This value describes whether all of the
           advertised bundles are required to unbundle a complete understanding of the bundled
           information (all) or if any one of the listed bundle URIs is sufficient (any).

       bundle.heuristic
           If this string-valued key exists, then the bundle list is designed to work well with
           incremental git fetch commands. The heuristic signals that there are additional keys
           available for each bundle that help determine which subset of bundles the client
           should download. The only value currently understood is creationToken.

       bundle.<id>.*
           The bundle.<id>.*  keys are used to describe a single item in the bundle list, grouped
           under <id> for identification purposes.

       bundle.<id>.uri
           This string value defines the URI by which Git can reach the contents of this <id>.
           This URI may be a bundle file or another bundle list.

       checkout.defaultRemote
           When you run git checkout <something> or git switch <something> and only have one
           remote, it may implicitly fall back on checking out and tracking e.g.
           origin/<something>. This stops working as soon as you have more than one remote with a
           <something> reference. This setting allows for setting the name of a preferred remote
           that should always win when it comes to disambiguation. The typical use-case is to set
           this to origin.

           Currently this is used by git-switch(1) and git-checkout(1) when git checkout
           <something> or git switch <something> will checkout the <something> branch on another
           remote, and by git-worktree(1) when git worktree add refers to a remote branch. This
           setting might be used for other checkout-like commands or functionality in the future.

       checkout.guess
           Provides the default value for the --guess or --no-guess option in git checkout and
           git switch. See git-switch(1) and git-checkout(1).

       checkout.workers
           The number of parallel workers to use when updating the working tree. The default is
           one, i.e. sequential execution. If set to a value less than one, Git will use as many
           workers as the number of logical cores available. This setting and
           checkout.thresholdForParallelism affect all commands that perform checkout. E.g.
           checkout, clone, reset, sparse-checkout, etc.

           Note: Parallel checkout usually delivers better performance for repositories located
           on SSDs or over NFS. For repositories on spinning disks and/or machines with a small
           number of cores, the default sequential checkout often performs better. The size and
           compression level of a repository might also influence how well the parallel version
           performs.

       checkout.thresholdForParallelism
           When running parallel checkout with a small number of files, the cost of subprocess
           spawning and inter-process communication might outweigh the parallelization gains.
           This setting allows you to define the minimum number of files for which parallel
           checkout should be attempted. The default is 100.

       clean.requireForce
           A boolean to make git-clean refuse to delete files unless -f is given. Defaults to
           true.

       clone.defaultRemoteName
           The name of the remote to create when cloning a repository. Defaults to origin. It can
           be overridden by passing the --origin command-line option to git-clone(1).

       clone.rejectShallow
           Reject cloning a repository if it is a shallow one; this can be overridden by passing
           the --reject-shallow option on the command line. See git-clone(1).

       clone.filterSubmodules
           If a partial clone filter is provided (see --filter in git-rev-list(1)) and
           --recurse-submodules is used, also apply the filter to submodules.

       color.advice
           A boolean to enable/disable color in hints (e.g. when a push failed, see advice.*  for
           a list). May be set to always, false (or never) or auto (or true), in which case
           colors are used only when the error output goes to a terminal. If unset, then the
           value of color.ui is used (auto by default).

       color.advice.hint
           Use customized color for hints.

       color.blame.highlightRecent
           Specify the line annotation color for git blame --color-by-age depending upon the age
           of the line.

           This setting should be set to a comma-separated list of color and date settings,
           starting and ending with a color, the dates should be set from oldest to newest. The
           metadata will be colored with the specified colors if the line was introduced before
           the given timestamp, overwriting older timestamped colors.

           Instead of an absolute timestamp relative timestamps work as well, e.g.  2.weeks.ago
           is valid to address anything older than 2 weeks.

           It defaults to blue,12 month ago,white,1 month ago,red, which colors everything older
           than one year blue, recent changes between one month and one year old are kept white,
           and lines introduced within the last month are colored red.

       color.blame.repeatedLines
           Use the specified color to colorize line annotations for git blame --color-lines, if
           they come from the same commit as the preceding line. Defaults to cyan.

       color.branch
           A boolean to enable/disable color in the output of git-branch(1). May be set to
           always, false (or never) or auto (or true), in which case colors are used only when
           the output is to a terminal. If unset, then the value of color.ui is used (auto by
           default).

       color.branch.<slot>
           Use customized color for branch coloration.  <slot> is one of current (the current
           branch), local (a local branch), remote (a remote-tracking branch in refs/remotes/),
           upstream (upstream tracking branch), plain (other refs).

       color.diff
           Whether to use ANSI escape sequences to add color to patches. If this is set to
           always, git-diff(1), git-log(1), and git-show(1) will use color for all patches. If it
           is set to true or auto, those commands will only use color when output is to the
           terminal. If unset, then the value of color.ui is used (auto by default).

           This does not affect git-format-patch(1) or the git-diff-* plumbing commands. Can be
           overridden on the command line with the --color[=<when>] option.

       color.diff.<slot>
           Use customized color for diff colorization.  <slot> specifies which part of the patch
           to use the specified color, and is one of context (context text - plain is a
           historical synonym), meta (metainformation), frag (hunk header), func (function in
           hunk header), old (removed lines), new (added lines), commit (commit headers),
           whitespace (highlighting whitespace errors), oldMoved (deleted lines), newMoved (added
           lines), oldMovedDimmed, oldMovedAlternative, oldMovedAlternativeDimmed,
           newMovedDimmed, newMovedAlternative newMovedAlternativeDimmed (See the <mode> setting
           of --color-moved in git-diff(1) for details), contextDimmed, oldDimmed, newDimmed,
           contextBold, oldBold, and newBold (see git-range-diff(1) for details).

       color.decorate.<slot>
           Use customized color for git log --decorate output.  <slot> is one of branch,
           remoteBranch, tag, stash or HEAD for local branches, remote-tracking branches, tags,
           stash and HEAD, respectively and grafted for grafted commits.

       color.grep
           When set to always, always highlight matches. When false (or never), never. When set
           to true or auto, use color only when the output is written to the terminal. If unset,
           then the value of color.ui is used (auto by default).

       color.grep.<slot>
           Use customized color for grep colorization.  <slot> specifies which part of the line
           to use the specified color, and is one of

           context
               non-matching text in context lines (when using -A, -B, or -C)

           filename
               filename prefix (when not using -h)

           function
               function name lines (when using -p)

           lineNumber
               line number prefix (when using -n)

           column
               column number prefix (when using --column)

           match
               matching text (same as setting matchContext and matchSelected)

           matchContext
               matching text in context lines

           matchSelected
               matching text in selected lines. Also, used to customize the following git-log(1)
               subcommands: --grep, --author, and --committer.

           selected
               non-matching text in selected lines. Also, used to customize the following git-
               log(1) subcommands: --grep, --author and --committer.

           separator
               separators between fields on a line (:, -, and =) and between hunks (--)

       color.interactive
           When set to always, always use colors for interactive prompts and displays (such as
           those used by "git-add --interactive" and "git-clean --interactive"). When false (or
           never), never. When set to true or auto, use colors only when the output is to the
           terminal. If unset, then the value of color.ui is used (auto by default).

       color.interactive.<slot>
           Use customized color for git add --interactive and git clean --interactive output.
           <slot> may be prompt, header, help or error, for four distinct types of normal output
           from interactive commands.

       color.pager
           A boolean to specify whether auto color modes should colorize output going to the
           pager. Defaults to true; set this to false if your pager does not understand ANSI
           color codes.

       color.push
           A boolean to enable/disable color in push errors. May be set to always, false (or
           never) or auto (or true), in which case colors are used only when the error output
           goes to a terminal. If unset, then the value of color.ui is used (auto by default).

       color.push.error
           Use customized color for push errors.

       color.remote
           If set, keywords at the start of the line are highlighted. The keywords are "error",
           "warning", "hint" and "success", and are matched case-insensitively. May be set to
           always, false (or never) or auto (or true). If unset, then the value of color.ui is
           used (auto by default).

       color.remote.<slot>
           Use customized color for each remote keyword.  <slot> may be hint, warning, success or
           error which match the corresponding keyword.

       color.showBranch
           A boolean to enable/disable color in the output of git-show-branch(1). May be set to
           always, false (or never) or auto (or true), in which case colors are used only when
           the output is to a terminal. If unset, then the value of color.ui is used (auto by
           default).

       color.status
           A boolean to enable/disable color in the output of git-status(1). May be set to
           always, false (or never) or auto (or true), in which case colors are used only when
           the output is to a terminal. If unset, then the value of color.ui is used (auto by
           default).

       color.status.<slot>
           Use customized color for status colorization.  <slot> is one of header (the header
           text of the status message), added or updated (files which are added but not
           committed), changed (files which are changed but not added in the index), untracked
           (files which are not tracked by Git), branch (the current branch), nobranch (the color
           the no branch warning is shown in, defaulting to red), localBranch or remoteBranch
           (the local and remote branch names, respectively, when branch and tracking information
           is displayed in the status short-format), or unmerged (files which have unmerged
           changes).

       color.transport
           A boolean to enable/disable color when pushes are rejected. May be set to always,
           false (or never) or auto (or true), in which case colors are used only when the error
           output goes to a terminal. If unset, then the value of color.ui is used (auto by
           default).

       color.transport.rejected
           Use customized color when a push was rejected.

       color.ui
           This variable determines the default value for variables such as color.diff and
           color.grep that control the use of color per command family. Its scope will expand as
           more commands learn configuration to set a default for the --color option. Set it to
           false or never if you prefer Git commands not to use color unless enabled explicitly
           with some other configuration or the --color option. Set it to always if you want all
           output not intended for machine consumption to use color, to true or auto (this is the
           default since Git 1.8.4) if you want such output to use color when written to the
           terminal.

       column.ui
           Specify whether supported commands should output in columns. This variable consists of
           a list of tokens separated by spaces or commas:

           These options control when the feature should be enabled (defaults to never):

           always
               always show in columns

           never
               never show in columns

           auto
               show in columns if the output is to the terminal

           These options control layout (defaults to column). Setting any of these implies always
           if none of always, never, or auto are specified.

           column
               fill columns before rows

           row
               fill rows before columns

           plain
               show in one column

           Finally, these options can be combined with a layout option (defaults to nodense):

           dense
               make unequal size columns to utilize more space

           nodense
               make equal size columns

       column.branch
           Specify whether to output branch listing in git branch in columns. See column.ui for
           details.

       column.clean
           Specify the layout when listing items in git clean -i, which always shows files and
           directories in columns. See column.ui for details.

       column.status
           Specify whether to output untracked files in git status in columns. See column.ui for
           details.

       column.tag
           Specify whether to output tag listings in git tag in columns. See column.ui for
           details.

       commit.cleanup
           This setting overrides the default of the --cleanup option in git commit. See git-
           commit(1) for details. Changing the default can be useful when you always want to keep
           lines that begin with the comment character # in your log message, in which case you
           would do git config commit.cleanup whitespace (note that you will have to remove the
           help lines that begin with # in the commit log template yourself, if you do this).

       commit.gpgSign
           A boolean to specify whether all commits should be GPG signed. Use of this option when
           doing operations such as rebase can result in a large number of commits being signed.
           It may be convenient to use an agent to avoid typing your GPG passphrase several
           times.

       commit.status
           A boolean to enable/disable inclusion of status information in the commit message
           template when using an editor to prepare the commit message. Defaults to true.

       commit.template
           Specify the pathname of a file to use as the template for new commit messages.

       commit.verbose
           A boolean or int to specify the level of verbosity with git commit. See git-commit(1).

       commitGraph.generationVersion
           Specifies the type of generation number version to use when writing or reading the
           commit-graph file. If version 1 is specified, then the corrected commit dates will not
           be written or read. Defaults to 2.

       commitGraph.maxNewFilters
           Specifies the default value for the --max-new-filters option of git commit-graph write
           (c.f., git-commit-graph(1)).

       commitGraph.readChangedPaths
           If true, then git will use the changed-path Bloom filters in the commit-graph file (if
           it exists, and they are present). Defaults to true. See git-commit-graph(1) for more
           information.

       completion.commands
           This is only used by git-completion.bash to add or remove commands from the list of
           completed commands. Normally only porcelain commands and a few select others are
           completed. You can add more commands, separated by space, in this variable. Prefixing
           the command with - will remove it from the existing list.

       core.fileMode
           Tells Git if the executable bit of files in the working tree is to be honored.

           Some filesystems lose the executable bit when a file that is marked as executable is
           checked out, or checks out a non-executable file with executable bit on.  git-clone(1)
           or git-init(1) probe the filesystem to see if it handles the executable bit correctly
           and this variable is automatically set as necessary.

           A repository, however, may be on a filesystem that handles the filemode correctly, and
           this variable is set to true when created, but later may be made accessible from
           another environment that loses the filemode (e.g. exporting ext4 via CIFS mount,
           visiting a Cygwin created repository with Git for Windows or Eclipse). In such a case
           it may be necessary to set this variable to false. See git-update-index(1).

           The default is true (when core.filemode is not specified in the config file).

       core.hideDotFiles
           (Windows-only) If true, mark newly-created directories and files whose name starts
           with a dot as hidden. If dotGitOnly, only the .git/ directory is hidden, but no other
           files starting with a dot. The default mode is dotGitOnly.

       core.ignoreCase
           Internal variable which enables various workarounds to enable Git to work better on
           filesystems that are not case sensitive, like APFS, HFS+, FAT, NTFS, etc. For example,
           if a directory listing finds "makefile" when Git expects "Makefile", Git will assume
           it is really the same file, and continue to remember it as "Makefile".

           The default is false, except git-clone(1) or git-init(1) will probe and set
           core.ignoreCase true if appropriate when the repository is created.

           Git relies on the proper configuration of this variable for your operating and file
           system. Modifying this value may result in unexpected behavior.

       core.precomposeUnicode
           This option is only used by Mac OS implementation of Git. When
           core.precomposeUnicode=true, Git reverts the unicode decomposition of filenames done
           by Mac OS. This is useful when sharing a repository between Mac OS and Linux or
           Windows. (Git for Windows 1.7.10 or higher is needed, or Git under cygwin 1.7). When
           false, file names are handled fully transparent by Git, which is backward compatible
           with older versions of Git.

       core.protectHFS
           If set to true, do not allow checkout of paths that would be considered equivalent to
           .git on an HFS+ filesystem. Defaults to true on Mac OS, and false elsewhere.

       core.protectNTFS
           If set to true, do not allow checkout of paths that would cause problems with the NTFS
           filesystem, e.g. conflict with 8.3 "short" names. Defaults to true on Windows, and
           false elsewhere.

       core.fsmonitor
           If set to true, enable the built-in file system monitor daemon for this working
           directory (git-fsmonitor--daemon(1)).

           Like hook-based file system monitors, the built-in file system monitor can speed up
           Git commands that need to refresh the Git index (e.g.  git status) in a working
           directory with many files. The built-in monitor eliminates the need to install and
           maintain an external third-party tool.

           The built-in file system monitor is currently available only on a limited set of
           supported platforms. Currently, this includes Windows and MacOS.

               Otherwise, this variable contains the pathname of the "fsmonitor"
               hook command.

           This hook command is used to identify all files that may have changed since the
           requested date/time. This information is used to speed up git by avoiding unnecessary
           scanning of files that have not changed.

           See the "fsmonitor-watchman" section of githooks(5).

           Note that if you concurrently use multiple versions of Git, such as one version on the
           command line and another version in an IDE tool, that the definition of core.fsmonitor
           was extended to allow boolean values in addition to hook pathnames. Git versions
           2.35.1 and prior will not understand the boolean values and will consider the "true"
           or "false" values as hook pathnames to be invoked. Git versions 2.26 thru 2.35.1
           default to hook protocol V2 and will fall back to no fsmonitor (full scan). Git
           versions prior to 2.26 default to hook protocol V1 and will silently assume there were
           no changes to report (no scan), so status commands may report incomplete results. For
           this reason, it is best to upgrade all of your Git versions before using the built-in
           file system monitor.

       core.fsmonitorHookVersion
           Sets the protocol version to be used when invoking the "fsmonitor" hook.

           There are currently versions 1 and 2. When this is not set, version 2 will be tried
           first and if it fails then version 1 will be tried. Version 1 uses a timestamp as
           input to determine which files have changes since that time but some monitors like
           Watchman have race conditions when used with a timestamp. Version 2 uses an opaque
           string so that the monitor can return something that can be used to determine what
           files have changed without race conditions.

       core.trustctime
           If false, the ctime differences between the index and the working tree are ignored;
           useful when the inode change time is regularly modified by something outside Git (file
           system crawlers and some backup systems). See git-update-index(1). True by default.

       core.splitIndex
           If true, the split-index feature of the index will be used. See git-update-index(1).
           False by default.

       core.untrackedCache
           Determines what to do about the untracked cache feature of the index. It will be kept,
           if this variable is unset or set to keep. It will automatically be added if set to
           true. And it will automatically be removed, if set to false. Before setting it to
           true, you should check that mtime is working properly on your system. See git-update-
           index(1).  keep by default, unless feature.manyFiles is enabled which sets this
           setting to true by default.

       core.checkStat
           When missing or is set to default, many fields in the stat structure are checked to
           detect if a file has been modified since Git looked at it. When this configuration
           variable is set to minimal, sub-second part of mtime and ctime, the uid and gid of the
           owner of the file, the inode number (and the device number, if Git was compiled to use
           it), are excluded from the check among these fields, leaving only the whole-second
           part of mtime (and ctime, if core.trustCtime is set) and the filesize to be checked.

           There are implementations of Git that do not leave usable values in some fields (e.g.
           JGit); by excluding these fields from the comparison, the minimal mode may help
           interoperability when the same repository is used by these other systems at the same
           time.

       core.quotePath
           Commands that output paths (e.g.  ls-files, diff), will quote "unusual" characters in
           the pathname by enclosing the pathname in double-quotes and escaping those characters
           with backslashes in the same way C escapes control characters (e.g.  \t for TAB, \n
           for LF, \\ for backslash) or bytes with values larger than 0x80 (e.g. octal \302\265
           for "micro" in UTF-8). If this variable is set to false, bytes higher than 0x80 are
           not considered "unusual" any more. Double-quotes, backslash and control characters are
           always escaped regardless of the setting of this variable. A simple space character is
           not considered "unusual". Many commands can output pathnames completely verbatim using
           the -z option. The default value is true.

       core.eol
           Sets the line ending type to use in the working directory for files that are marked as
           text (either by having the text attribute set, or by having text=auto and Git
           auto-detecting the contents as text). Alternatives are lf, crlf and native, which uses
           the platform’s native line ending. The default value is native. See gitattributes(5)
           for more information on end-of-line conversion. Note that this value is ignored if
           core.autocrlf is set to true or input.

       core.safecrlf
           If true, makes Git check if converting CRLF is reversible when end-of-line conversion
           is active. Git will verify if a command modifies a file in the work tree either
           directly or indirectly. For example, committing a file followed by checking out the
           same file should yield the original file in the work tree. If this is not the case for
           the current setting of core.autocrlf, Git will reject the file. The variable can be
           set to "warn", in which case Git will only warn about an irreversible conversion but
           continue the operation.

           CRLF conversion bears a slight chance of corrupting data. When it is enabled, Git will
           convert CRLF to LF during commit and LF to CRLF during checkout. A file that contains
           a mixture of LF and CRLF before the commit cannot be recreated by Git. For text files
           this is the right thing to do: it corrects line endings such that we have only LF line
           endings in the repository. But for binary files that are accidentally classified as
           text the conversion can corrupt data.

           If you recognize such corruption early you can easily fix it by setting the conversion
           type explicitly in .gitattributes. Right after committing you still have the original
           file in your work tree and this file is not yet corrupted. You can explicitly tell Git
           that this file is binary and Git will handle the file appropriately.

           Unfortunately, the desired effect of cleaning up text files with mixed line endings
           and the undesired effect of corrupting binary files cannot be distinguished. In both
           cases CRLFs are removed in an irreversible way. For text files this is the right thing
           to do because CRLFs are line endings, while for binary files converting CRLFs corrupts
           data.

           Note, this safety check does not mean that a checkout will generate a file identical
           to the original file for a different setting of core.eol and core.autocrlf, but only
           for the current one. For example, a text file with LF would be accepted with
           core.eol=lf and could later be checked out with core.eol=crlf, in which case the
           resulting file would contain CRLF, although the original file contained LF. However,
           in both work trees the line endings would be consistent, that is either all LF or all
           CRLF, but never mixed. A file with mixed line endings would be reported by the
           core.safecrlf mechanism.

       core.autocrlf
           Setting this variable to "true" is the same as setting the text attribute to "auto" on
           all files and core.eol to "crlf". Set to true if you want to have CRLF line endings in
           your working directory and the repository has LF line endings. This variable can be
           set to input, in which case no output conversion is performed.

       core.checkRoundtripEncoding
           A comma and/or whitespace separated list of encodings that Git performs UTF-8 round
           trip checks on if they are used in an working-tree-encoding attribute (see
           gitattributes(5)). The default value is SHIFT-JIS.

       core.symlinks
           If false, symbolic links are checked out as small plain files that contain the link
           text.  git-update-index(1) and git-add(1) will not change the recorded type to regular
           file. Useful on filesystems like FAT that do not support symbolic links.

           The default is true, except git-clone(1) or git-init(1) will probe and set
           core.symlinks false if appropriate when the repository is created.

       core.gitProxy
           A "proxy command" to execute (as command host port) instead of establishing direct
           connection to the remote server when using the Git protocol for fetching. If the
           variable value is in the "COMMAND for DOMAIN" format, the command is applied only on
           hostnames ending with the specified domain string. This variable may be set multiple
           times and is matched in the given order; the first match wins.

           Can be overridden by the GIT_PROXY_COMMAND environment variable (which always applies
           universally, without the special "for" handling).

           The special string none can be used as the proxy command to specify that no proxy be
           used for a given domain pattern. This is useful for excluding servers inside a
           firewall from proxy use, while defaulting to a common proxy for external domains.

       core.sshCommand
           If this variable is set, git fetch and git push will use the specified command instead
           of ssh when they need to connect to a remote system. The command is in the same form
           as the GIT_SSH_COMMAND environment variable and is overridden when the environment
           variable is set.

       core.ignoreStat
           If true, Git will avoid using lstat() calls to detect if files have changed by setting
           the "assume-unchanged" bit for those tracked files which it has updated identically in
           both the index and working tree.

           When files are modified outside of Git, the user will need to stage the modified files
           explicitly (e.g. see Examples section in git-update-index(1)). Git will not normally
           detect changes to those files.

           This is useful on systems where lstat() calls are very slow, such as CIFS/Microsoft
           Windows.

           False by default.

       core.preferSymlinkRefs
           Instead of the default "symref" format for HEAD and other symbolic reference files,
           use symbolic links. This is sometimes needed to work with old scripts that expect HEAD
           to be a symbolic link.

       core.alternateRefsCommand
           When advertising tips of available history from an alternate, use the shell to execute
           the specified command instead of git-for-each-ref(1). The first argument is the
           absolute path of the alternate. Output must contain one hex object id per line (i.e.,
           the same as produced by git for-each-ref --format='%(objectname)').

           Note that you cannot generally put git for-each-ref directly into the config value, as
           it does not take a repository path as an argument (but you can wrap the command above
           in a shell script).

       core.alternateRefsPrefixes
           When listing references from an alternate, list only references that begin with the
           given prefix. Prefixes match as if they were given as arguments to git-for-each-
           ref(1). To list multiple prefixes, separate them with whitespace. If
           core.alternateRefsCommand is set, setting core.alternateRefsPrefixes has no effect.

       core.bare
           If true this repository is assumed to be bare and has no working directory associated
           with it. If this is the case a number of commands that require a working directory
           will be disabled, such as git-add(1) or git-merge(1).

           This setting is automatically guessed by git-clone(1) or git-init(1) when the
           repository was created. By default a repository that ends in "/.git" is assumed to be
           not bare (bare = false), while all other repositories are assumed to be bare (bare =
           true).

       core.worktree
           Set the path to the root of the working tree. If GIT_COMMON_DIR environment variable
           is set, core.worktree is ignored and not used for determining the root of working
           tree. This can be overridden by the GIT_WORK_TREE environment variable and the
           --work-tree command-line option. The value can be an absolute path or relative to the
           path to the .git directory, which is either specified by --git-dir or GIT_DIR, or
           automatically discovered. If --git-dir or GIT_DIR is specified but none of
           --work-tree, GIT_WORK_TREE and core.worktree is specified, the current working
           directory is regarded as the top level of your working tree.

           Note that this variable is honored even when set in a configuration file in a ".git"
           subdirectory of a directory and its value differs from the latter directory (e.g.
           "/path/to/.git/config" has core.worktree set to "/different/path"), which is most
           likely a misconfiguration. Running Git commands in the "/path/to" directory will still
           use "/different/path" as the root of the work tree and can cause confusion unless you
           know what you are doing (e.g. you are creating a read-only snapshot of the same index
           to a location different from the repository’s usual working tree).

       core.logAllRefUpdates
           Enable the reflog. Updates to a ref <ref> is logged to the file "$GIT_DIR/logs/<ref>",
           by appending the new and old SHA-1, the date/time and the reason of the update, but
           only when the file exists. If this configuration variable is set to true, missing
           "$GIT_DIR/logs/<ref>" file is automatically created for branch heads (i.e. under
           refs/heads/), remote refs (i.e. under refs/remotes/), note refs (i.e. under
           refs/notes/), and the symbolic ref HEAD. If it is set to always, then a missing reflog
           is automatically created for any ref under refs/.

           This information can be used to determine what commit was the tip of a branch "2 days
           ago".

           This value is true by default in a repository that has a working directory associated
           with it, and false by default in a bare repository.

       core.repositoryFormatVersion
           Internal variable identifying the repository format and layout version.

       core.sharedRepository
           When group (or true), the repository is made shareable between several users in a
           group (making sure all the files and objects are group-writable). When all (or world
           or everybody), the repository will be readable by all users, additionally to being
           group-shareable. When umask (or false), Git will use permissions reported by umask(2).
           When 0xxx, where 0xxx is an octal number, files in the repository will have this mode
           value.  0xxx will override user’s umask value (whereas the other options will only
           override requested parts of the user’s umask value). Examples: 0660 will make the repo
           read/write-able for the owner and group, but inaccessible to others (equivalent to
           group unless umask is e.g.  0022).  0640 is a repository that is group-readable but
           not group-writable. See git-init(1). False by default.

       core.warnAmbiguousRefs
           If true, Git will warn you if the ref name you passed it is ambiguous and might match
           multiple refs in the repository. True by default.

       core.compression
           An integer -1..9, indicating a default compression level. -1 is the zlib default. 0
           means no compression, and 1..9 are various speed/size tradeoffs, 9 being slowest. If
           set, this provides a default to other compression variables, such as
           core.looseCompression and pack.compression.

       core.looseCompression
           An integer -1..9, indicating the compression level for objects that are not in a pack
           file. -1 is the zlib default. 0 means no compression, and 1..9 are various speed/size
           tradeoffs, 9 being slowest. If not set, defaults to core.compression. If that is not
           set, defaults to 1 (best speed).

       core.packedGitWindowSize
           Number of bytes of a pack file to map into memory in a single mapping operation.
           Larger window sizes may allow your system to process a smaller number of large pack
           files more quickly. Smaller window sizes will negatively affect performance due to
           increased calls to the operating system’s memory manager, but may improve performance
           when accessing a large number of large pack files.

           Default is 1 MiB if NO_MMAP was set at compile time, otherwise 32 MiB on 32 bit
           platforms and 1 GiB on 64 bit platforms. This should be reasonable for all
           users/operating systems. You probably do not need to adjust this value.

           Common unit suffixes of k, m, or g are supported.

       core.packedGitLimit
           Maximum number of bytes to map simultaneously into memory from pack files. If Git
           needs to access more than this many bytes at once to complete an operation it will
           unmap existing regions to reclaim virtual address space within the process.

           Default is 256 MiB on 32 bit platforms and 32 TiB (effectively unlimited) on 64 bit
           platforms. This should be reasonable for all users/operating systems, except on the
           largest projects. You probably do not need to adjust this value.

           Common unit suffixes of k, m, or g are supported.

       core.deltaBaseCacheLimit
           Maximum number of bytes per thread to reserve for caching base objects that may be
           referenced by multiple deltified objects. By storing the entire decompressed base
           objects in a cache Git is able to avoid unpacking and decompressing frequently used
           base objects multiple times.

           Default is 96 MiB on all platforms. This should be reasonable for all users/operating
           systems, except on the largest projects. You probably do not need to adjust this
           value.

           Common unit suffixes of k, m, or g are supported.

       core.bigFileThreshold
           The size of files considered "big", which as discussed below changes the behavior of
           numerous git commands, as well as how such files are stored within the repository. The
           default is 512 MiB. Common unit suffixes of k, m, or g are supported.

           Files above the configured limit will be:

           •   Stored deflated in packfiles, without attempting delta compression.

               The default limit is primarily set with this use-case in mind. With it, most
               projects will have their source code and other text files delta compressed, but
               not larger binary media files.

               Storing large files without delta compression avoids excessive memory usage, at
               the slight expense of increased disk usage.

           •   Will be treated as if they were labeled "binary" (see gitattributes(5)). e.g.
               git-log(1) and git-diff(1) will not compute diffs for files above this limit.

           •   Will generally be streamed when written, which avoids excessive memory usage, at
               the cost of some fixed overhead. Commands that make use of this include git-
               archive(1), git-fast-import(1), git-index-pack(1), git-unpack-objects(1) and git-
               fsck(1).

       core.excludesFile
           Specifies the pathname to the file that contains patterns to describe paths that are
           not meant to be tracked, in addition to .gitignore (per-directory) and
           .git/info/exclude. Defaults to $XDG_CONFIG_HOME/git/ignore. If $XDG_CONFIG_HOME is
           either not set or empty, $HOME/.config/git/ignore is used instead. See gitignore(5).

       core.askPass
           Some commands (e.g. svn and http interfaces) that interactively ask for a password can
           be told to use an external program given via the value of this variable. Can be
           overridden by the GIT_ASKPASS environment variable. If not set, fall back to the value
           of the SSH_ASKPASS environment variable or, failing that, a simple password prompt.
           The external program shall be given a suitable prompt as command-line argument and
           write the password on its STDOUT.

       core.attributesFile
           In addition to .gitattributes (per-directory) and .git/info/attributes, Git looks into
           this file for attributes (see gitattributes(5)). Path expansions are made the same way
           as for core.excludesFile. Its default value is $XDG_CONFIG_HOME/git/attributes. If
           $XDG_CONFIG_HOME is either not set or empty, $HOME/.config/git/attributes is used
           instead.

       core.hooksPath
           By default Git will look for your hooks in the $GIT_DIR/hooks directory. Set this to
           different path, e.g.  /etc/git/hooks, and Git will try to find your hooks in that
           directory, e.g.  /etc/git/hooks/pre-receive instead of in $GIT_DIR/hooks/pre-receive.

           The path can be either absolute or relative. A relative path is taken as relative to
           the directory where the hooks are run (see the "DESCRIPTION" section of githooks(5)).

           This configuration variable is useful in cases where you’d like to centrally configure
           your Git hooks instead of configuring them on a per-repository basis, or as a more
           flexible and centralized alternative to having an init.templateDir where you’ve
           changed default hooks.

       core.editor
           Commands such as commit and tag that let you edit messages by launching an editor use
           the value of this variable when it is set, and the environment variable GIT_EDITOR is
           not set. See git-var(1).

       core.commentChar, core.commentString
           Commands such as commit and tag that let you edit messages consider a line that begins
           with this character commented, and removes them after the editor returns (default #).

           If set to "auto", git-commit would select a character that is not the beginning
           character of any line in existing commit messages.

           Note that these two variables are aliases of each other, and in modern versions of Git
           you are free to use a string (e.g., // or ⁑⁕⁑) with commentChar. Versions of Git prior
           to v2.45.0 will ignore commentString but will reject a value of commentChar that
           consists of more than a single ASCII byte. If you plan to use your config with older
           and newer versions of Git, you may want to specify both:

               [core]
               # single character for older versions
               commentChar = "#"
               # string for newer versions (which will override commentChar
               # because it comes later in the file)
               commentString = "//"

       core.filesRefLockTimeout
           The length of time, in milliseconds, to retry when trying to lock an individual
           reference. Value 0 means not to retry at all; -1 means to try indefinitely. Default is
           100 (i.e., retry for 100ms).

       core.packedRefsTimeout
           The length of time, in milliseconds, to retry when trying to lock the packed-refs
           file. Value 0 means not to retry at all; -1 means to try indefinitely. Default is 1000
           (i.e., retry for 1 second).

       core.pager
           Text viewer for use by Git commands (e.g., less). The value is meant to be interpreted
           by the shell. The order of preference is the $GIT_PAGER environment variable, then
           core.pager configuration, then $PAGER, and then the default chosen at compile time
           (usually less).

           When the LESS environment variable is unset, Git sets it to FRX (if LESS environment
           variable is set, Git does not change it at all). If you want to selectively override
           Git’s default setting for LESS, you can set core.pager to e.g.  less -S. This will be
           passed to the shell by Git, which will translate the final command to LESS=FRX less
           -S. The environment does not set the S option but the command line does, instructing
           less to truncate long lines. Similarly, setting core.pager to less -+F will deactivate
           the F option specified by the environment from the command-line, deactivating the
           "quit if one screen" behavior of less. One can specifically activate some flags for
           particular commands: for example, setting pager.blame to less -S enables line
           truncation only for git blame.

           Likewise, when the LV environment variable is unset, Git sets it to -c. You can
           override this setting by exporting LV with another value or setting core.pager to lv
           +c.

       core.whitespace
           A comma separated list of common whitespace problems to notice.  git diff will use
           color.diff.whitespace to highlight them, and git apply --whitespace=error will
           consider them as errors. You can prefix - to disable any of them (e.g.
           -trailing-space):

           •   blank-at-eol treats trailing whitespaces at the end of the line as an error
               (enabled by default).

           •   space-before-tab treats a space character that appears immediately before a tab
               character in the initial indent part of the line as an error (enabled by default).

           •   indent-with-non-tab treats a line that is indented with space characters instead
               of the equivalent tabs as an error (not enabled by default).

           •   tab-in-indent treats a tab character in the initial indent part of the line as an
               error (not enabled by default).

           •   blank-at-eof treats blank lines added at the end of file as an error (enabled by
               default).

           •   trailing-space is a short-hand to cover both blank-at-eol and blank-at-eof.

           •   cr-at-eol treats a carriage-return at the end of line as part of the line
               terminator, i.e. with it, trailing-space does not trigger if the character before
               such a carriage-return is not a whitespace (not enabled by default).

           •   tabwidth=<n> tells how many character positions a tab occupies; this is relevant
               for indent-with-non-tab and when Git fixes tab-in-indent errors. The default tab
               width is 8. Allowed values are 1 to 63.

       core.fsync
           A comma-separated list of components of the repository that should be hardened via the
           core.fsyncMethod when created or modified. You can disable hardening of any component
           by prefixing it with a -. Items that are not hardened may be lost in the event of an
           unclean system shutdown. Unless you have special requirements, it is recommended that
           you leave this option empty or pick one of committed, added, or all.

           When this configuration is encountered, the set of components starts with the platform
           default value, disabled components are removed, and additional components are added.
           none resets the state so that the platform default is ignored.

           The empty string resets the fsync configuration to the platform default. The default
           on most platforms is equivalent to core.fsync=committed,-loose-object, which has good
           performance, but risks losing recent work in the event of an unclean system shutdown.

           •   none clears the set of fsynced components.

           •   loose-object hardens objects added to the repo in loose-object form.

           •   pack hardens objects added to the repo in packfile form.

           •   pack-metadata hardens packfile bitmaps and indexes.

           •   commit-graph hardens the commit-graph file.

           •   index hardens the index when it is modified.

           •   objects is an aggregate option that is equivalent to loose-object,pack.

           •   reference hardens references modified in the repo.

           •   derived-metadata is an aggregate option that is equivalent to
               pack-metadata,commit-graph.

           •   committed is an aggregate option that is currently equivalent to objects. This
               mode sacrifices some performance to ensure that work that is committed to the
               repository with git commit or similar commands is hardened.

           •   added is an aggregate option that is currently equivalent to committed,index. This
               mode sacrifices additional performance to ensure that the results of commands like
               git add and similar operations are hardened.

           •   all is an aggregate option that syncs all individual components above.

       core.fsyncMethod
           A value indicating the strategy Git will use to harden repository data using fsync and
           related primitives.

           •   fsync uses the fsync() system call or platform equivalents.

           •   writeout-only issues pagecache writeback requests, but depending on the filesystem
               and storage hardware, data added to the repository may not be durable in the event
               of a system crash. This is the default mode on macOS.

           •   batch enables a mode that uses writeout-only flushes to stage multiple updates in
               the disk writeback cache and then does a single full fsync of a dummy file to
               trigger the disk cache flush at the end of the operation.

               Currently batch mode only applies to loose-object files. Other repository data is
               made durable as if fsync was specified. This mode is expected to be as safe as
               fsync on macOS for repos stored on HFS+ or APFS filesystems and on Windows for
               repos stored on NTFS or ReFS filesystems.

       core.fsyncObjectFiles
           This boolean will enable fsync() when writing object files. This setting is
           deprecated. Use core.fsync instead.

           This setting affects data added to the Git repository in loose-object form. When set
           to true, Git will issue an fsync or similar system call to flush caches so that
           loose-objects remain consistent in the face of a unclean system shutdown.

       core.preloadIndex
           Enable parallel index preload for operations like git diff

           This can speed up operations like git diff and git status especially on filesystems
           like NFS that have weak caching semantics and thus relatively high IO latencies. When
           enabled, Git will do the index comparison to the filesystem data in parallel, allowing
           overlapping IO’s. Defaults to true.

       core.unsetenvvars
           Windows-only: comma-separated list of environment variables' names that need to be
           unset before spawning any other process. Defaults to PERL5LIB to account for the fact
           that Git for Windows insists on using its own Perl interpreter.

       core.restrictinheritedhandles
           Windows-only: override whether spawned processes inherit only standard file handles
           (stdin, stdout and stderr) or all handles. Can be auto, true or false. Defaults to
           auto, which means true on Windows 7 and later, and false on older Windows versions.

       core.createObject
           You can set this to link, in which case a hardlink followed by a delete of the source
           are used to make sure that object creation will not overwrite existing objects.

           On some file system/operating system combinations, this is unreliable. Set this config
           setting to rename there; however, this will remove the check that makes sure that
           existing object files will not get overwritten.

       core.notesRef
           When showing commit messages, also show notes which are stored in the given ref. The
           ref must be fully qualified. If the given ref does not exist, it is not an error but
           means that no notes should be printed.

           This setting defaults to "refs/notes/commits", and it can be overridden by the
           GIT_NOTES_REF environment variable. See git-notes(1).

       core.commitGraph
           If true, then git will read the commit-graph file (if it exists) to parse the graph
           structure of commits. Defaults to true. See git-commit-graph(1) for more information.

       core.useReplaceRefs
           If set to false, behave as if the --no-replace-objects option was given on the command
           line. See git(1) and git-replace(1) for more information.

       core.multiPackIndex
           Use the multi-pack-index file to track multiple packfiles using a single index. See
           git-multi-pack-index(1) for more information. Defaults to true.

       core.sparseCheckout
           Enable "sparse checkout" feature. See git-sparse-checkout(1) for more information.

       core.sparseCheckoutCone
           Enables the "cone mode" of the sparse checkout feature. When the sparse-checkout file
           contains a limited set of patterns, this mode provides significant performance
           advantages. The "non-cone mode" can be requested to allow specifying more flexible
           patterns by setting this variable to false. See git-sparse-checkout(1) for more
           information.

       core.abbrev
           Set the length object names are abbreviated to. If unspecified or set to "auto", an
           appropriate value is computed based on the approximate number of packed objects in
           your repository, which hopefully is enough for abbreviated object names to stay unique
           for some time. If set to "no", no abbreviation is made and the object names are shown
           in their full length. The minimum length is 4.

       core.maxTreeDepth
           The maximum depth Git is willing to recurse while traversing a tree (e.g., "a/b/cde/f"
           has a depth of 4). This is a fail-safe to allow Git to abort cleanly, and should not
           generally need to be adjusted. The default is 4096.

       credential.helper
           Specify an external helper to be called when a username or password credential is
           needed; the helper may consult external storage to avoid prompting the user for the
           credentials. This is normally the name of a credential helper with possible arguments,
           but may also be an absolute path with arguments or, if preceded by !, shell commands.

           Note that multiple helpers may be defined. See gitcredentials(7) for details and
           examples.

       credential.useHttpPath
           When acquiring credentials, consider the "path" component of an http or https URL to
           be important. Defaults to false. See gitcredentials(7) for more information.

       credential.username
           If no username is set for a network authentication, use this username by default. See
           credential.<context>.* below, and gitcredentials(7).

       credential.<url>.*
           Any of the credential.* options above can be applied selectively to some credentials.
           For example, "credential.https://example.com.username" would set the default username
           only for https connections to example.com. See gitcredentials(7) for details on how
           URLs are matched.

       credentialCache.ignoreSIGHUP
           Tell git-credential-cache—daemon to ignore SIGHUP, instead of quitting.

       credentialStore.lockTimeoutMS
           The length of time, in milliseconds, for git-credential-store to retry when trying to
           lock the credentials file. A value of 0 means not to retry at all; -1 means to try
           indefinitely. Default is 1000 (i.e., retry for 1s).

       diff.autoRefreshIndex
           When using git diff to compare with work tree files, do not consider stat-only changes
           as changed. Instead, silently run git update-index --refresh to update the cached stat
           information for paths whose contents in the work tree match the contents in the index.
           This option defaults to true. Note that this affects only git diff Porcelain, and not
           lower level diff commands such as git diff-files.

       diff.dirstat
           A comma separated list of --dirstat parameters specifying the default behavior of the
           --dirstat option to git-diff(1) and friends. The defaults can be overridden on the
           command line (using --dirstat=<param1,param2,...>). The fallback defaults (when not
           changed by diff.dirstat) are changes,noncumulative,3. The following parameters are
           available:

           changes
               Compute the dirstat numbers by counting the lines that have been removed from the
               source, or added to the destination. This ignores the amount of pure code
               movements within a file. In other words, rearranging lines in a file is not
               counted as much as other changes. This is the default behavior when no parameter
               is given.

           lines
               Compute the dirstat numbers by doing the regular line-based diff analysis, and
               summing the removed/added line counts. (For binary files, count 64-byte chunks
               instead, since binary files have no natural concept of lines). This is a more
               expensive --dirstat behavior than the changes behavior, but it does count
               rearranged lines within a file as much as other changes. The resulting output is
               consistent with what you get from the other --*stat options.

           files
               Compute the dirstat numbers by counting the number of files changed. Each changed
               file counts equally in the dirstat analysis. This is the computationally cheapest
               --dirstat behavior, since it does not have to look at the file contents at all.

           cumulative
               Count changes in a child directory for the parent directory as well. Note that
               when using cumulative, the sum of the percentages reported may exceed 100%. The
               default (non-cumulative) behavior can be specified with the noncumulative
               parameter.

           <limit>
               An integer parameter specifies a cut-off percent (3% by default). Directories
               contributing less than this percentage of the changes are not shown in the output.

           Example: The following will count changed files, while ignoring directories with less
           than 10% of the total amount of changed files, and accumulating child directory counts
           in the parent directories: files,10,cumulative.

       diff.statNameWidth
           Limit the width of the filename part in --stat output. If set, applies to all commands
           generating --stat output except format-patch.

       diff.statGraphWidth
           Limit the width of the graph part in --stat output. If set, applies to all commands
           generating --stat output except format-patch.

       diff.context
           Generate diffs with <n> lines of context instead of the default of 3. This value is
           overridden by the -U option.

       diff.interHunkContext
           Show the context between diff hunks, up to the specified number of lines, thereby
           fusing the hunks that are close to each other. This value serves as the default for
           the --inter-hunk-context command line option.

       diff.external
           If this config variable is set, diff generation is not performed using the internal
           diff machinery, but using the given command. Can be overridden with the
           ‘GIT_EXTERNAL_DIFF’ environment variable. The command is called with parameters as
           described under "git Diffs" in git(1). Note: if you want to use an external diff
           program only on a subset of your files, you might want to use gitattributes(5)
           instead.

       diff.ignoreSubmodules
           Sets the default value of --ignore-submodules. Note that this affects only git diff
           Porcelain, and not lower level diff commands such as git diff-files.  git checkout and
           git switch also honor this setting when reporting uncommitted changes. Setting it to
           all disables the submodule summary normally shown by git commit and git status when
           status.submoduleSummary is set unless it is overridden by using the
           --ignore-submodules command-line option. The git submodule commands are not affected
           by this setting. By default this is set to untracked so that any untracked submodules
           are ignored.

       diff.mnemonicPrefix
           If set, git diff uses a prefix pair that is different from the standard "a/" and "b/"
           depending on what is being compared. When this configuration is in effect, reverse
           diff output also swaps the order of the prefixes:

           git diff
               compares the (i)ndex and the (w)ork tree;

           git diff HEAD
               compares a (c)ommit and the (w)ork tree;

           git diff --cached
               compares a (c)ommit and the (i)ndex;

           git diff HEAD:file1 file2
               compares an (o)bject and a (w)ork tree entity;

           git diff --no-index a b
               compares two non-git things (1) and (2).

       diff.noPrefix
           If set, git diff does not show any source or destination prefix.

       diff.srcPrefix
           If set, git diff uses this source prefix. Defaults to "a/".

       diff.dstPrefix
           If set, git diff uses this destination prefix. Defaults to "b/".

       diff.relative
           If set to true, git diff does not show changes outside of the directory and show
           pathnames relative to the current directory.

       diff.orderFile
           File indicating how to order files within a diff. See the -O option to git-diff(1) for
           details. If diff.orderFile is a relative pathname, it is treated as relative to the
           top of the working tree.

       diff.renameLimit
           The number of files to consider in the exhaustive portion of copy/rename detection;
           equivalent to the git diff option -l. If not set, the default value is currently 1000.
           This setting has no effect if rename detection is turned off.

       diff.renames
           Whether and how Git detects renames. If set to "false", rename detection is disabled.
           If set to "true", basic rename detection is enabled. If set to "copies" or "copy", Git
           will detect copies, as well. Defaults to true. Note that this affects only git diff
           Porcelain like git-diff(1) and git-log(1), and not lower level commands such as git-
           diff-files(1).

       diff.suppressBlankEmpty
           A boolean to inhibit the standard behavior of printing a space before each empty
           output line. Defaults to false.

       diff.submodule
           Specify the format in which differences in submodules are shown. The "short" format
           just shows the names of the commits at the beginning and end of the range. The "log"
           format lists the commits in the range like git-submodule(1) summary does. The "diff"
           format shows an inline diff of the changed contents of the submodule. Defaults to
           "short".

       diff.wordRegex
           A POSIX Extended Regular Expression used to determine what is a "word" when performing
           word-by-word difference calculations. Character sequences that match the regular
           expression are "words", all other characters are ignorable whitespace.

       diff.<driver>.command
           The custom diff driver command. See gitattributes(5) for details.

       diff.<driver>.xfuncname
           The regular expression that the diff driver should use to recognize the hunk header. A
           built-in pattern may also be used. See gitattributes(5) for details.

       diff.<driver>.binary
           Set this option to true to make the diff driver treat files as binary. See
           gitattributes(5) for details.

       diff.<driver>.textconv
           The command that the diff driver should call to generate the text-converted version of
           a file. The result of the conversion is used to generate a human-readable diff. See
           gitattributes(5) for details.

       diff.<driver>.wordRegex
           The regular expression that the diff driver should use to split words in a line. See
           gitattributes(5) for details.

       diff.<driver>.cachetextconv
           Set this option to true to make the diff driver cache the text conversion outputs. See
           gitattributes(5) for details.

       diff.indentHeuristic
           Set this option to false to disable the default heuristics that shift diff hunk
           boundaries to make patches easier to read.

       diff.algorithm
           Choose a diff algorithm. The variants are as follows:

           default, myers
               The basic greedy diff algorithm. Currently, this is the default.

           minimal
               Spend extra time to make sure the smallest possible diff is produced.

           patience
               Use "patience diff" algorithm when generating patches.

           histogram
               This algorithm extends the patience algorithm to "support low-occurrence common
               elements".

       diff.wsErrorHighlight
           Highlight whitespace errors in the context, old or new lines of the diff. Multiple
           values are separated by comma, none resets previous values, default reset the list to
           new and all is a shorthand for old,new,context. The whitespace errors are colored with
           color.diff.whitespace. The command line option --ws-error-highlight=<kind> overrides
           this setting.

       diff.colorMoved
           If set to either a valid <mode> or a true value, moved lines in a diff are colored
           differently, for details of valid modes see --color-moved in git-diff(1). If simply
           set to true the default color mode will be used. When set to false, moved lines are
           not colored.

       diff.colorMovedWS
           When moved lines are colored using e.g. the diff.colorMoved setting, this option
           controls the <mode> how spaces are treated. For details of valid modes see
           --color-moved-ws in git-diff(1).

       diff.tool
           Controls which diff tool is used by git-difftool(1). This variable overrides the value
           configured in merge.tool. The list below shows the valid built-in values. Any other
           value is treated as a custom diff tool and requires that a corresponding
           difftool.<tool>.cmd variable is defined.

       diff.guitool
           Controls which diff tool is used by git-difftool(1) when the -g/--gui flag is
           specified. This variable overrides the value configured in merge.guitool. The list
           below shows the valid built-in values. Any other value is treated as a custom diff
           tool and requires that a corresponding difftool.<guitool>.cmd variable is defined.

       difftool.<tool>.cmd
           Specify the command to invoke the specified diff tool. The specified command is
           evaluated in shell with the following variables available: LOCAL is set to the name of
           the temporary file containing the contents of the diff pre-image and REMOTE is set to
           the name of the temporary file containing the contents of the diff post-image.

           See the --tool=<tool> option in git-difftool(1) for more details.

       difftool.<tool>.path
           Override the path for the given tool. This is useful in case your tool is not in the
           PATH.

       difftool.trustExitCode
           Exit difftool if the invoked diff tool returns a non-zero exit status.

           See the --trust-exit-code option in git-difftool(1) for more details.

       difftool.prompt
           Prompt before each invocation of the diff tool.

       difftool.guiDefault
           Set true to use the diff.guitool by default (equivalent to specifying the --gui
           argument), or auto to select diff.guitool or diff.tool depending on the presence of a
           DISPLAY environment variable value. The default is false, where the --gui argument
           must be provided explicitly for the diff.guitool to be used.

       extensions.objectFormat
           Specify the hash algorithm to use. The acceptable values are sha1 and sha256. If not
           specified, sha1 is assumed. It is an error to specify this key unless
           core.repositoryFormatVersion is 1.

           Note that this setting should only be set by git-init(1) or git-clone(1). Trying to
           change it after initialization will not work and will produce hard-to-diagnose issues.

       extensions.compatObjectFormat
           Specify a compatitbility hash algorithm to use. The acceptable values are sha1 and
           sha256. The value specified must be different from the value of
           extensions.objectFormat. This allows client level interoperability between git
           repositories whose objectFormat matches this compatObjectFormat. In particular when
           fully implemented the pushes and pulls from a repository in whose objectFormat matches
           compatObjectFormat. As well as being able to use oids encoded in compatObjectFormat in
           addition to oids encoded with objectFormat to locally specify objects.

       extensions.refStorage
           Specify the ref storage format to use. The acceptable values are:

           •   files for loose files with packed-refs. This is the default.

           •   reftable for the reftable format. This format is experimental and its internals
               are subject to change.

               It is an error to specify this key unless core.repositoryFormatVersion is 1.

               Note that this setting should only be set by git-init(1) or git-clone(1). Trying
               to change it after initialization will not work and will produce hard-to-diagnose
               issues.

       extensions.worktreeConfig
           If enabled, then worktrees will load config settings from the $GIT_DIR/config.worktree
           file in addition to the $GIT_COMMON_DIR/config file. Note that $GIT_COMMON_DIR and
           $GIT_DIR are the same for the main working tree, while other working trees have
           $GIT_DIR equal to $GIT_COMMON_DIR/worktrees/<id>/. The settings in the config.worktree
           file will override settings from any other config files.

           When enabling extensions.worktreeConfig, you must be careful to move certain values
           from the common config file to the main working tree’s config.worktree file, if
           present:

           •   core.worktree must be moved from $GIT_COMMON_DIR/config to
               $GIT_COMMON_DIR/config.worktree.

           •   If core.bare is true, then it must be moved from $GIT_COMMON_DIR/config to
               $GIT_COMMON_DIR/config.worktree.

               It may also be beneficial to adjust the locations of core.sparseCheckout and
               core.sparseCheckoutCone depending on your desire for customizable sparse-checkout
               settings for each worktree. By default, the git sparse-checkout builtin enables
               extensions.worktreeConfig, assigns these config values on a per-worktree basis,
               and uses the $GIT_DIR/info/sparse-checkout file to specify the sparsity for each
               worktree independently. See git-sparse-checkout(1) for more details.

               For historical reasons, extensions.worktreeConfig is respected regardless of the
               core.repositoryFormatVersion setting.

       fastimport.unpackLimit
           If the number of objects imported by git-fast-import(1) is below this limit, then the
           objects will be unpacked into loose object files. However, if the number of imported
           objects equals or exceeds this limit, then the pack will be stored as a pack. Storing
           the pack from a fast-import can make the import operation complete faster, especially
           on slow filesystems. If not set, the value of transfer.unpackLimit is used instead.

       feature.*
           The config settings that start with feature.  modify the defaults of a group of other
           config settings. These groups are created by the Git developer community as
           recommended defaults and are subject to change. In particular, new config options may
           be added with different defaults.

       feature.experimental
           Enable config options that are new to Git, and are being considered for future
           defaults. Config settings included here may be added or removed with each release,
           including minor version updates. These settings may have unintended interactions since
           they are so new. Please enable this setting if you are interested in providing
           feedback on experimental features. The new default values are:

           •   fetch.negotiationAlgorithm=skipping may improve fetch negotiation times by
               skipping more commits at a time, reducing the number of round trips.

           •   pack.useBitmapBoundaryTraversal=true may improve bitmap traversal times by walking
               fewer objects.

           •   pack.allowPackReuse=multi may improve the time it takes to create a pack by
               reusing objects from multiple packs instead of just one.

       feature.manyFiles
           Enable config options that optimize for repos with many files in the working
           directory. With many files, commands such as git status and git checkout may be slow
           and these new defaults improve performance:

           •   index.skipHash=true speeds up index writes by not computing a trailing checksum.
               Note that this will cause Git versions earlier than 2.13.0 to refuse to parse the
               index and Git versions earlier than 2.40.0 will report a corrupted index during
               git fsck.

           •   index.version=4 enables path-prefix compression in the index.

           •   core.untrackedCache=true enables the untracked cache. This setting assumes that
               mtime is working on your machine.

       fetch.recurseSubmodules
           This option controls whether git fetch (and the underlying fetch in git pull) will
           recursively fetch into populated submodules. This option can be set either to a
           boolean value or to on-demand. Setting it to a boolean changes the behavior of fetch
           and pull to recurse unconditionally into submodules when set to true or to not recurse
           at all when set to false. When set to on-demand, fetch and pull will only recurse into
           a populated submodule when its superproject retrieves a commit that updates the
           submodule’s reference. Defaults to on-demand, or to the value of submodule.recurse if
           set.

       fetch.fsckObjects
           If it is set to true, git-fetch-pack will check all fetched objects. See
           transfer.fsckObjects for what’s checked. Defaults to false. If not set, the value of
           transfer.fsckObjects is used instead.

       fetch.fsck.<msg-id>
           Acts like fsck.<msg-id>, but is used by git-fetch-pack(1) instead of git-fsck(1). See
           the fsck.<msg-id> documentation for details.

       fetch.fsck.skipList
           Acts like fsck.skipList, but is used by git-fetch-pack(1) instead of git-fsck(1). See
           the fsck.skipList documentation for details.

       fetch.unpackLimit
           If the number of objects fetched over the Git native transfer is below this limit,
           then the objects will be unpacked into loose object files. However if the number of
           received objects equals or exceeds this limit then the received pack will be stored as
           a pack, after adding any missing delta bases. Storing the pack from a push can make
           the push operation complete faster, especially on slow filesystems. If not set, the
           value of transfer.unpackLimit is used instead.

       fetch.prune
           If true, fetch will automatically behave as if the --prune option was given on the
           command line. See also remote.<name>.prune and the PRUNING section of git-fetch(1).

       fetch.pruneTags
           If true, fetch will automatically behave as if the refs/tags/*:refs/tags/* refspec was
           provided when pruning, if not set already. This allows for setting both this option
           and fetch.prune to maintain a 1=1 mapping to upstream refs. See also
           remote.<name>.pruneTags and the PRUNING section of git-fetch(1).

       fetch.all
           If true, fetch will attempt to update all available remotes. This behavior can be
           overridden by passing --no-all or by explicitly specifying one or more remote(s) to
           fetch from. Defaults to false.

       fetch.output
           Control how ref update status is printed. Valid values are full and compact. Default
           value is full. See the OUTPUT section in git-fetch(1) for details.

       fetch.negotiationAlgorithm
           Control how information about the commits in the local repository is sent when
           negotiating the contents of the packfile to be sent by the server. Set to
           "consecutive" to use an algorithm that walks over consecutive commits checking each
           one. Set to "skipping" to use an algorithm that skips commits in an effort to converge
           faster, but may result in a larger-than-necessary packfile; or set to "noop" to not
           send any information at all, which will almost certainly result in a
           larger-than-necessary packfile, but will skip the negotiation step. Set to "default"
           to override settings made previously and use the default behaviour. The default is
           normally "consecutive", but if feature.experimental is true, then the default is
           "skipping". Unknown values will cause git fetch to error out.

           See also the --negotiate-only and --negotiation-tip options to git-fetch(1).

       fetch.showForcedUpdates
           Set to false to enable --no-show-forced-updates in git-fetch(1) and git-pull(1)
           commands. Defaults to true.

       fetch.parallel
           Specifies the maximal number of fetch operations to be run in parallel at a time
           (submodules, or remotes when the --multiple option of git-fetch(1) is in effect).

           A value of 0 will give some reasonable default. If unset, it defaults to 1.

           For submodules, this setting can be overridden using the submodule.fetchJobs config
           setting.

       fetch.writeCommitGraph
           Set to true to write a commit-graph after every git fetch command that downloads a
           pack-file from a remote. Using the --split option, most executions will create a very
           small commit-graph file on top of the existing commit-graph file(s). Occasionally,
           these files will merge and the write may take longer. Having an updated commit-graph
           file helps performance of many Git commands, including git merge-base, git push -f,
           and git log --graph. Defaults to false.

       fetch.bundleURI
           This value stores a URI for downloading Git object data from a bundle URI before
           performing an incremental fetch from the origin Git server. This is similar to how the
           --bundle-uri option behaves in git-clone(1).  git clone --bundle-uri will set the
           fetch.bundleURI value if the supplied bundle URI contains a bundle list that is
           organized for incremental fetches.

           If you modify this value and your repository has a fetch.bundleCreationToken value,
           then remove that fetch.bundleCreationToken value before fetching from the new bundle
           URI.

       fetch.bundleCreationToken
           When using fetch.bundleURI to fetch incrementally from a bundle list that uses the
           "creationToken" heuristic, this config value stores the maximum creationToken value of
           the downloaded bundles. This value is used to prevent downloading bundles in the
           future if the advertised creationToken is not strictly larger than this value.

           The creation token values are chosen by the provider serving the specific bundle URI.
           If you modify the URI at fetch.bundleURI, then be sure to remove the value for the
           fetch.bundleCreationToken value before fetching.

       filter.<driver>.clean
           The command which is used to convert the content of a worktree file to a blob upon
           checkin. See gitattributes(5) for details.

       filter.<driver>.smudge
           The command which is used to convert the content of a blob object to a worktree file
           upon checkout. See gitattributes(5) for details.

       format.attach
           Enable multipart/mixed attachments as the default for format-patch. The value can also
           be a double quoted string which will enable attachments as the default and set the
           value as the boundary. See the --attach option in git-format-patch(1). To countermand
           an earlier value, set it to an empty string.

       format.from
           Provides the default value for the --from option to format-patch. Accepts a boolean
           value, or a name and email address. If false, format-patch defaults to --no-from,
           using commit authors directly in the "From:" field of patch mails. If true,
           format-patch defaults to --from, using your committer identity in the "From:" field of
           patch mails and including a "From:" field in the body of the patch mail if different.
           If set to a non-boolean value, format-patch uses that value instead of your committer
           identity. Defaults to false.

       format.forceInBodyFrom
           Provides the default value for the --[no-]force-in-body-from option to format-patch.
           Defaults to false.

       format.numbered
           A boolean which can enable or disable sequence numbers in patch subjects. It defaults
           to "auto" which enables it only if there is more than one patch. It can be enabled or
           disabled for all messages by setting it to "true" or "false". See --numbered option in
           git-format-patch(1).

       format.headers
           Additional email headers to include in a patch to be submitted by mail. See git-
           format-patch(1).

       format.to, format.cc
           Additional recipients to include in a patch to be submitted by mail. See the --to and
           --cc options in git-format-patch(1).

       format.subjectPrefix
           The default for format-patch is to output files with the [PATCH] subject prefix. Use
           this variable to change that prefix.

       format.coverFromDescription
           The default mode for format-patch to determine which parts of the cover letter will be
           populated using the branch’s description. See the --cover-from-description option in
           git-format-patch(1).

       format.signature
           The default for format-patch is to output a signature containing the Git version
           number. Use this variable to change that default. Set this variable to the empty
           string ("") to suppress signature generation.

       format.signatureFile
           Works just like format.signature except the contents of the file specified by this
           variable will be used as the signature.

       format.suffix
           The default for format-patch is to output files with the suffix .patch. Use this
           variable to change that suffix (make sure to include the dot if you want it).

       format.encodeEmailHeaders
           Encode email headers that have non-ASCII characters with "Q-encoding" (described in
           RFC 2047) for email transmission. Defaults to true.

       format.pretty
           The default pretty format for log/show/whatchanged command. See git-log(1), git-
           show(1), git-whatchanged(1).

       format.thread
           The default threading style for git format-patch. Can be a boolean value, or shallow
           or deep.  shallow threading makes every mail a reply to the head of the series, where
           the head is chosen from the cover letter, the --in-reply-to, and the first patch mail,
           in this order.  deep threading makes every mail a reply to the previous one. A true
           boolean value is the same as shallow, and a false value disables threading.

       format.signOff
           A boolean value which lets you enable the -s/--signoff option of format-patch by
           default.  Note: Adding the Signed-off-by trailer to a patch should be a conscious act
           and means that you certify you have the rights to submit this work under the same open
           source license. Please see the SubmittingPatches document for further discussion.

       format.coverLetter
           A boolean that controls whether to generate a cover-letter when format-patch is
           invoked, but in addition can be set to "auto", to generate a cover-letter only when
           there’s more than one patch. Default is false.

       format.outputDirectory
           Set a custom directory to store the resulting files instead of the current working
           directory. All directory components will be created.

       format.filenameMaxLength
           The maximum length of the output filenames generated by the format-patch command;
           defaults to 64. Can be overridden by the --filename-max-length=<n> command line
           option.

       format.useAutoBase
           A boolean value which lets you enable the --base=auto option of format-patch by
           default. Can also be set to "whenAble" to allow enabling --base=auto if a suitable
           base is available, but to skip adding base info otherwise without the format dying.

       format.notes
           Provides the default value for the --notes option to format-patch. Accepts a boolean
           value, or a ref which specifies where to get notes. If false, format-patch defaults to
           --no-notes. If true, format-patch defaults to --notes. If set to a non-boolean value,
           format-patch defaults to --notes=<ref>, where ref is the non-boolean value. Defaults
           to false.

           If one wishes to use the ref refs/notes/true, please use that literal instead.

           This configuration can be specified multiple times in order to allow multiple notes
           refs to be included. In that case, it will behave similarly to multiple
           --[no-]notes[=] options passed in. That is, a value of true will show the default
           notes, a value of <ref> will also show notes from that notes ref and a value of false
           will negate previous configurations and not show notes.

           For example,

               [format]
                       notes = true
                       notes = foo
                       notes = false
                       notes = bar

           will only show notes from refs/notes/bar.

       format.mboxrd
           A boolean value which enables the robust "mboxrd" format when --stdout is in use to
           escape "^>+From " lines.

       format.noprefix
           If set, do not show any source or destination prefix in patches. This is equivalent to
           the diff.noprefix option used by git diff (but which is not respected by
           format-patch). Note that by setting this, the receiver of any patches you generate
           will have to apply them using the -p0 option.

       fsck.<msg-id>
           During fsck git may find issues with legacy data which wouldn’t be generated by
           current versions of git, and which wouldn’t be sent over the wire if
           transfer.fsckObjects was set. This feature is intended to support working with legacy
           repositories containing such data.

           Setting fsck.<msg-id> will be picked up by git-fsck(1), but to accept pushes of such
           data set receive.fsck.<msg-id> instead, or to clone or fetch it set
           fetch.fsck.<msg-id>.

           The rest of the documentation discusses fsck.*  for brevity, but the same applies for
           the corresponding receive.fsck.*  and fetch.fsck.*. variables.

           Unlike variables like color.ui and core.editor, the receive.fsck.<msg-id> and
           fetch.fsck.<msg-id> variables will not fall back on the fsck.<msg-id> configuration if
           they aren’t set. To uniformly configure the same fsck settings in different
           circumstances, all three of them must be set to the same values.

           When fsck.<msg-id> is set, errors can be switched to warnings and vice versa by
           configuring the fsck.<msg-id> setting where the <msg-id> is the fsck message ID and
           the value is one of error, warn or ignore. For convenience, fsck prefixes the
           error/warning with the message ID, e.g. "missingEmail: invalid author/committer line -
           missing email" means that setting fsck.missingEmail = ignore will hide that issue.

           In general, it is better to enumerate existing objects with problems with
           fsck.skipList, instead of listing the kind of breakages these problematic objects
           share to be ignored, as doing the latter will allow new instances of the same
           breakages go unnoticed.

           Setting an unknown fsck.<msg-id> value will cause fsck to die, but doing the same for
           receive.fsck.<msg-id> and fetch.fsck.<msg-id> will only cause git to warn.

           See the Fsck Messages section of git-fsck(1) for supported values of <msg-id>.

       fsck.skipList
           The path to a list of object names (i.e. one unabbreviated SHA-1 per line) that are
           known to be broken in a non-fatal way and should be ignored. On versions of Git 2.20
           and later, comments (#), empty lines, and any leading and trailing whitespace are
           ignored. Everything but a SHA-1 per line will error out on older versions.

           This feature is useful when an established project should be accepted despite early
           commits containing errors that can be safely ignored, such as invalid committer email
           addresses. Note: corrupt objects cannot be skipped with this setting.

           Like fsck.<msg-id> this variable has corresponding receive.fsck.skipList and
           fetch.fsck.skipList variants.

           Unlike variables like color.ui and core.editor the receive.fsck.skipList and
           fetch.fsck.skipList variables will not fall back on the fsck.skipList configuration if
           they aren’t set. To uniformly configure the same fsck settings in different
           circumstances, all three of them must be set to the same values.

           Older versions of Git (before 2.20) documented that the object names list should be
           sorted. This was never a requirement; the object names could appear in any order, but
           when reading the list we tracked whether the list was sorted for the purposes of an
           internal binary search implementation, which could save itself some work with an
           already sorted list. Unless you had a humongous list there was no reason to go out of
           your way to pre-sort the list. After Git version 2.20 a hash implementation is used
           instead, so there’s now no reason to pre-sort the list.

       fsmonitor.allowRemote
           By default, the fsmonitor daemon refuses to work with network-mounted repositories.
           Setting fsmonitor.allowRemote to true overrides this behavior. Only respected when
           core.fsmonitor is set to true.

       fsmonitor.socketDir
           This Mac OS-specific option, if set, specifies the directory in which to create the
           Unix domain socket used for communication between the fsmonitor daemon and various Git
           commands. The directory must reside on a native Mac OS filesystem. Only respected when
           core.fsmonitor is set to true.

       gc.aggressiveDepth
           The depth parameter used in the delta compression algorithm used by git gc
           --aggressive. This defaults to 50, which is the default for the --depth option when
           --aggressive isn’t in use.

           See the documentation for the --depth option in git-repack(1) for more details.

       gc.aggressiveWindow
           The window size parameter used in the delta compression algorithm used by git gc
           --aggressive. This defaults to 250, which is a much more aggressive window size than
           the default --window of 10.

           See the documentation for the --window option in git-repack(1) for more details.

       gc.auto
           When there are approximately more than this many loose objects in the repository, git
           gc --auto will pack them. Some Porcelain commands use this command to perform a
           light-weight garbage collection from time to time. The default value is 6700.

           Setting this to 0 disables not only automatic packing based on the number of loose
           objects, but also any other heuristic git gc --auto will otherwise use to determine if
           there’s work to do, such as gc.autoPackLimit.

       gc.autoPackLimit
           When there are more than this many packs that are not marked with *.keep file in the
           repository, git gc --auto consolidates them into one larger pack. The default value is
           50. Setting this to 0 disables it. Setting gc.auto to 0 will also disable this.

           See the gc.bigPackThreshold configuration variable below. When in use, it’ll affect
           how the auto pack limit works.

       gc.autoDetach
           Make git gc --auto return immediately and run in the background if the system supports
           it. Default is true.

       gc.bigPackThreshold
           If non-zero, all non-cruft packs larger than this limit are kept when git gc is run.
           This is very similar to --keep-largest-pack except that all non-cruft packs that meet
           the threshold are kept, not just the largest pack. Defaults to zero. Common unit
           suffixes of k, m, or g are supported.

           Note that if the number of kept packs is more than gc.autoPackLimit, this
           configuration variable is ignored, all packs except the base pack will be repacked.
           After this the number of packs should go below gc.autoPackLimit and
           gc.bigPackThreshold should be respected again.

           If the amount of memory estimated for git repack to run smoothly is not available and
           gc.bigPackThreshold is not set, the largest pack will also be excluded (this is the
           equivalent of running git gc with --keep-largest-pack).

       gc.writeCommitGraph
           If true, then gc will rewrite the commit-graph file when git-gc(1) is run. When using
           git gc --auto the commit-graph will be updated if housekeeping is required. Default is
           true. See git-commit-graph(1) for details.

       gc.logExpiry
           If the file gc.log exists, then git gc --auto will print its content and exit with
           status zero instead of running unless that file is more than gc.logExpiry old. Default
           is "1.day". See gc.pruneExpire for more ways to specify its value.

       gc.packRefs
           Running git pack-refs in a repository renders it unclonable by Git versions prior to
           1.5.1.2 over dumb transports such as HTTP. This variable determines whether git gc
           runs git pack-refs. This can be set to notbare to enable it within all non-bare repos
           or it can be set to a boolean value. The default is true.

       gc.cruftPacks
           Store unreachable objects in a cruft pack (see git-repack(1)) instead of as loose
           objects. The default is true.

       gc.maxCruftSize
           Limit the size of new cruft packs when repacking. When specified in addition to
           --max-cruft-size, the command line option takes priority. See the --max-cruft-size
           option of git-repack(1).

       gc.pruneExpire
           When git gc is run, it will call prune --expire 2.weeks.ago (and repack --cruft
           --cruft-expiration 2.weeks.ago if using cruft packs via gc.cruftPacks or --cruft).
           Override the grace period with this config variable. The value "now" may be used to
           disable this grace period and always prune unreachable objects immediately, or "never"
           may be used to suppress pruning. This feature helps prevent corruption when git gc
           runs concurrently with another process writing to the repository; see the "NOTES"
           section of git-gc(1).

       gc.worktreePruneExpire
           When git gc is run, it calls git worktree prune --expire 3.months.ago. This config
           variable can be used to set a different grace period. The value "now" may be used to
           disable the grace period and prune $GIT_DIR/worktrees immediately, or "never" may be
           used to suppress pruning.

       gc.reflogExpire, gc.<pattern>.reflogExpire
           git reflog expire removes reflog entries older than this time; defaults to 90 days.
           The value "now" expires all entries immediately, and "never" suppresses expiration
           altogether. With "<pattern>" (e.g. "refs/stash") in the middle the setting applies
           only to the refs that match the <pattern>.

       gc.reflogExpireUnreachable, gc.<pattern>.reflogExpireUnreachable
           git reflog expire removes reflog entries older than this time and are not reachable
           from the current tip; defaults to 30 days. The value "now" expires all entries
           immediately, and "never" suppresses expiration altogether. With "<pattern>" (e.g.
           "refs/stash") in the middle, the setting applies only to the refs that match the
           <pattern>.

           These types of entries are generally created as a result of using git commit --amend
           or git rebase and are the commits prior to the amend or rebase occurring. Since these
           changes are not part of the current project most users will want to expire them
           sooner, which is why the default is more aggressive than gc.reflogExpire.

       gc.recentObjectsHook
           When considering whether or not to remove an object (either when generating a cruft
           pack or storing unreachable objects as loose), use the shell to execute the specified
           command(s). Interpret their output as object IDs which Git will consider as "recent",
           regardless of their age. By treating their mtimes as "now", any objects (and their
           descendants) mentioned in the output will be kept regardless of their true age.

           Output must contain exactly one hex object ID per line, and nothing else. Objects
           which cannot be found in the repository are ignored. Multiple hooks are supported, but
           all must exit successfully, else the operation (either generating a cruft pack or
           unpacking unreachable objects) will be halted.

       gc.repackFilter
           When repacking, use the specified filter to move certain objects into a separate
           packfile. See the --filter=<filter-spec> option of git-repack(1).

       gc.repackFilterTo
           When repacking and using a filter, see gc.repackFilter, the specified location will be
           used to create the packfile containing the filtered out objects.  WARNING: The
           specified location should be accessible, using for example the Git alternates
           mechanism, otherwise the repo could be considered corrupt by Git as it migh not be
           able to access the objects in that packfile. See the --filter-to=<dir> option of git-
           repack(1) and the objects/info/alternates section of gitrepository-layout(5).

       gc.rerereResolved
           Records of conflicted merge you resolved earlier are kept for this many days when git
           rerere gc is run. You can also use more human-readable "1.month.ago", etc. The default
           is 60 days. See git-rerere(1).

       gc.rerereUnresolved
           Records of conflicted merge you have not resolved are kept for this many days when git
           rerere gc is run. You can also use more human-readable "1.month.ago", etc. The default
           is 15 days. See git-rerere(1).

       gitcvs.commitMsgAnnotation
           Append this string to each commit message. Set to empty string to disable this
           feature. Defaults to "via git-CVS emulator".

       gitcvs.enabled
           Whether the CVS server interface is enabled for this repository. See git-cvsserver(1).

       gitcvs.logFile
           Path to a log file where the CVS server interface well... logs various stuff. See git-
           cvsserver(1).

       gitcvs.usecrlfattr
           If true, the server will look up the end-of-line conversion attributes for files to
           determine the -k modes to use. If the attributes force Git to treat a file as text,
           the -k mode will be left blank so CVS clients will treat it as text. If they suppress
           text conversion, the file will be set with -kb mode, which suppresses any newline
           munging the client might otherwise do. If the attributes do not allow the file type to
           be determined, then gitcvs.allBinary is used. See gitattributes(5).

       gitcvs.allBinary
           This is used if gitcvs.usecrlfattr does not resolve the correct -kb mode to use. If
           true, all unresolved files are sent to the client in mode -kb. This causes the client
           to treat them as binary files, which suppresses any newline munging it otherwise might
           do. Alternatively, if it is set to "guess", then the contents of the file are examined
           to decide if it is binary, similar to core.autocrlf.

       gitcvs.dbName
           Database used by git-cvsserver to cache revision information derived from the Git
           repository. The exact meaning depends on the used database driver, for SQLite (which
           is the default driver) this is a filename. Supports variable substitution (see git-
           cvsserver(1) for details). May not contain semicolons (;). Default: %Ggitcvs.%m.sqlite

       gitcvs.dbDriver
           Used Perl DBI driver. You can specify any available driver for this here, but it might
           not work. git-cvsserver is tested with DBD::SQLite, reported to work with DBD::Pg, and
           reported not to work with DBD::mysql. Experimental feature. May not contain double
           colons (:). Default: SQLite. See git-cvsserver(1).

       gitcvs.dbUser, gitcvs.dbPass
           Database user and password. Only useful if setting gitcvs.dbDriver, since SQLite has
           no concept of database users and/or passwords.  gitcvs.dbUser supports variable
           substitution (see git-cvsserver(1) for details).

       gitcvs.dbTableNamePrefix
           Database table name prefix. Prepended to the names of any database tables used,
           allowing a single database to be used for several repositories. Supports variable
           substitution (see git-cvsserver(1) for details). Any non-alphabetic characters will be
           replaced with underscores.

       All gitcvs variables except for gitcvs.usecrlfattr and gitcvs.allBinary can also be
       specified as gitcvs.<access_method>.<varname> (where access_method is one of "ext" and
       "pserver") to make them apply only for the given access method.

       gitweb.category, gitweb.description, gitweb.owner, gitweb.url
           See gitweb(1) for description.

       gitweb.avatar, gitweb.blame, gitweb.grep, gitweb.highlight, gitweb.patches,
       gitweb.pickaxe, gitweb.remote_heads, gitweb.showSizes, gitweb.snapshot
           See gitweb.conf(5) for description.

       gpg.program
           Use this custom program instead of "gpg" found on $PATH when making or verifying a PGP
           signature. The program must support the same command-line interface as GPG, namely, to
           verify a detached signature, "gpg --verify $signature - <$file" is run, and the
           program is expected to signal a good signature by exiting with code 0. To generate an
           ASCII-armored detached signature, the standard input of "gpg -bsau $key" is fed with
           the contents to be signed, and the program is expected to send the result to its
           standard output.

       gpg.format
           Specifies which key format to use when signing with --gpg-sign. Default is "openpgp".
           Other possible values are "x509", "ssh".

           See gitformat-signature(5) for the signature format, which differs based on the
           selected gpg.format.

       gpg.<format>.program
           Use this to customize the program used for the signing format you chose. (see
           gpg.program and gpg.format) gpg.program can still be used as a legacy synonym for
           gpg.openpgp.program. The default value for gpg.x509.program is "gpgsm" and
           gpg.ssh.program is "ssh-keygen".

       gpg.minTrustLevel
           Specifies a minimum trust level for signature verification. If this option is unset,
           then signature verification for merge operations requires a key with at least marginal
           trust. Other operations that perform signature verification require a key with at
           least undefined trust. Setting this option overrides the required trust-level for all
           operations. Supported values, in increasing order of significance:

           •   undefinednevermarginalfullyultimate

       gpg.ssh.defaultKeyCommand
           This command will be run when user.signingkey is not set and a ssh signature is
           requested. On successful exit a valid ssh public key prefixed with key:: is expected
           in the first line of its output. This allows for a script doing a dynamic lookup of
           the correct public key when it is impractical to statically configure user.signingKey.
           For example when keys or SSH Certificates are rotated frequently or selection of the
           right key depends on external factors unknown to git.

       gpg.ssh.allowedSignersFile
           A file containing ssh public keys which you are willing to trust. The file consists of
           one or more lines of principals followed by an ssh public key. e.g.:
           user1@example.com,user2@example.com ssh-rsa AAAAX1...  See ssh-keygen(1) "ALLOWED
           SIGNERS" for details. The principal is only used to identify the key and is available
           when verifying a signature.

           SSH has no concept of trust levels like gpg does. To be able to differentiate between
           valid signatures and trusted signatures the trust level of a signature verification is
           set to fully when the public key is present in the allowedSignersFile. Otherwise the
           trust level is undefined and git verify-commit/tag will fail.

           This file can be set to a location outside of the repository and every developer
           maintains their own trust store. A central repository server could generate this file
           automatically from ssh keys with push access to verify the code against. In a
           corporate setting this file is probably generated at a global location from automation
           that already handles developer ssh keys.

           A repository that only allows signed commits can store the file in the repository
           itself using a path relative to the top-level of the working tree. This way only
           committers with an already valid key can add or change keys in the keyring.

           Since OpensSSH 8.8 this file allows specifying a key lifetime using valid-after &
           valid-before options. Git will mark signatures as valid if the signing key was valid
           at the time of the signature’s creation. This allows users to change a signing key
           without invalidating all previously made signatures.

           Using a SSH CA key with the cert-authority option (see ssh-keygen(1) "CERTIFICATES")
           is also valid.

       gpg.ssh.revocationFile
           Either a SSH KRL or a list of revoked public keys (without the principal prefix). See
           ssh-keygen(1) for details. If a public key is found in this file then it will always
           be treated as having trust level "never" and signatures will show as invalid.

       grep.lineNumber
           If set to true, enable -n option by default.

       grep.column
           If set to true, enable the --column option by default.

       grep.patternType
           Set the default matching behavior. Using a value of basic, extended, fixed, or perl
           will enable the --basic-regexp, --extended-regexp, --fixed-strings, or --perl-regexp
           option accordingly, while the value default will use the grep.extendedRegexp option to
           choose between basic and extended.

       grep.extendedRegexp
           If set to true, enable --extended-regexp option by default. This option is ignored
           when the grep.patternType option is set to a value other than default.

       grep.threads
           Number of grep worker threads to use. If unset (or set to 0), Git will use as many
           threads as the number of logical cores available.

       grep.fullName
           If set to true, enable --full-name option by default.

       grep.fallbackToNoIndex
           If set to true, fall back to git grep --no-index if git grep is executed outside of a
           git repository. Defaults to false.

       gui.commitMsgWidth
           Defines how wide the commit message window is in the git-gui(1). "75" is the default.

       gui.diffContext
           Specifies how many context lines should be used in calls to diff made by the git-
           gui(1). The default is "5".

       gui.displayUntracked
           Determines if git-gui(1) shows untracked files in the file list. The default is
           "true".

       gui.encoding
           Specifies the default character encoding to use for displaying of file contents in
           git-gui(1) and gitk(1). It can be overridden by setting the encoding attribute for
           relevant files (see gitattributes(5)). If this option is not set, the tools default to
           the locale encoding.

       gui.matchTrackingBranch
           Determines if new branches created with git-gui(1) should default to tracking remote
           branches with matching names or not. Default: "false".

       gui.newBranchTemplate
           Is used as a suggested name when creating new branches using the git-gui(1).

       gui.pruneDuringFetch
           "true" if git-gui(1) should prune remote-tracking branches when performing a fetch.
           The default value is "false".

       gui.trustmtime
           Determines if git-gui(1) should trust the file modification timestamp or not. By
           default the timestamps are not trusted.

       gui.spellingDictionary
           Specifies the dictionary used for spell checking commit messages in the git-gui(1).
           When set to "none" spell checking is turned off.

       gui.fastCopyBlame
           If true, git gui blame uses -C instead of -C -C for original location detection. It
           makes blame significantly faster on huge repositories at the expense of less thorough
           copy detection.

       gui.copyBlameThreshold
           Specifies the threshold to use in git gui blame original location detection, measured
           in alphanumeric characters. See the git-blame(1) manual for more information on copy
           detection.

       gui.blamehistoryctx
           Specifies the radius of history context in days to show in gitk(1) for the selected
           commit, when the Show History Context menu item is invoked from git gui blame. If this
           variable is set to zero, the whole history is shown.

       guitool.<name>.cmd
           Specifies the shell command line to execute when the corresponding item of the git-
           gui(1) Tools menu is invoked. This option is mandatory for every tool. The command is
           executed from the root of the working directory, and in the environment it receives
           the name of the tool as GIT_GUITOOL, the name of the currently selected file as
           FILENAME, and the name of the current branch as CUR_BRANCH (if the head is detached,
           CUR_BRANCH is empty).

       guitool.<name>.needsFile
           Run the tool only if a diff is selected in the GUI. It guarantees that FILENAME is not
           empty.

       guitool.<name>.noConsole
           Run the command silently, without creating a window to display its output.

       guitool.<name>.noRescan
           Don’t rescan the working directory for changes after the tool finishes execution.

       guitool.<name>.confirm
           Show a confirmation dialog before actually running the tool.

       guitool.<name>.argPrompt
           Request a string argument from the user, and pass it to the tool through the ARGS
           environment variable. Since requesting an argument implies confirmation, the confirm
           option has no effect if this is enabled. If the option is set to true, yes, or 1, the
           dialog uses a built-in generic prompt; otherwise the exact value of the variable is
           used.

       guitool.<name>.revPrompt
           Request a single valid revision from the user, and set the REVISION environment
           variable. In other aspects this option is similar to argPrompt, and can be used
           together with it.

       guitool.<name>.revUnmerged
           Show only unmerged branches in the revPrompt subdialog. This is useful for tools
           similar to merge or rebase, but not for things like checkout or reset.

       guitool.<name>.title
           Specifies the title to use for the prompt dialog. The default is the tool name.

       guitool.<name>.prompt
           Specifies the general prompt string to display at the top of the dialog, before
           subsections for argPrompt and revPrompt. The default value includes the actual
           command.

       help.browser
           Specify the browser that will be used to display help in the web format. See git-
           help(1).

       help.format
           Override the default help format used by git-help(1). Values man, info, web and html
           are supported.  man is the default.  web and html are the same.

       help.autoCorrect
           If git detects typos and can identify exactly one valid command similar to the error,
           git will try to suggest the correct command or even run the suggestion automatically.
           Possible config values are:

           •   0 (default): show the suggested command.

           •   positive number: run the suggested command after specified deciseconds (0.1 sec).

           •   "immediate": run the suggested command immediately.

           •   "prompt": show the suggestion and prompt for confirmation to run the command.

           •   "never": don’t run or show any suggested command.

       help.htmlPath
           Specify the path where the HTML documentation resides. File system paths and URLs are
           supported. HTML pages will be prefixed with this path when help is displayed in the
           web format. This defaults to the documentation path of your Git installation.

       http.proxy
           Override the HTTP proxy, normally configured using the http_proxy, https_proxy, and
           all_proxy environment variables (see curl(1)). In addition to the syntax understood by
           curl, it is possible to specify a proxy string with a user name but no password, in
           which case git will attempt to acquire one in the same way it does for other
           credentials. See gitcredentials(7) for more information. The syntax thus is
           [protocol://][user[:password]@]proxyhost[:port]. This can be overridden on a
           per-remote basis; see remote.<name>.proxy

       http.proxyAuthMethod
           Set the method with which to authenticate against the HTTP proxy. This only takes
           effect if the configured proxy string contains a user name part (i.e. is of the form
           user@host or user@host:port). This can be overridden on a per-remote basis; see
           remote.<name>.proxyAuthMethod. Both can be overridden by the GIT_HTTP_PROXY_AUTHMETHOD
           environment variable. Possible values are:

           •   anyauth - Automatically pick a suitable authentication method. It is assumed that
               the proxy answers an unauthenticated request with a 407 status code and one or
               more Proxy-authenticate headers with supported authentication methods. This is the
               default.

           •   basic - HTTP Basic authentication

           •   digest - HTTP Digest authentication; this prevents the password from being
               transmitted to the proxy in clear text

           •   negotiate - GSS-Negotiate authentication (compare the --negotiate option of
               curl(1))

           •   ntlm - NTLM authentication (compare the --ntlm option of curl(1))

       http.proxySSLCert
           The pathname of a file that stores a client certificate to use to authenticate with an
           HTTPS proxy. Can be overridden by the GIT_PROXY_SSL_CERT environment variable.

       http.proxySSLKey
           The pathname of a file that stores a private key to use to authenticate with an HTTPS
           proxy. Can be overridden by the GIT_PROXY_SSL_KEY environment variable.

       http.proxySSLCertPasswordProtected
           Enable Git’s password prompt for the proxy SSL certificate. Otherwise OpenSSL will
           prompt the user, possibly many times, if the certificate or private key is encrypted.
           Can be overridden by the GIT_PROXY_SSL_CERT_PASSWORD_PROTECTED environment variable.

       http.proxySSLCAInfo
           Pathname to the file containing the certificate bundle that should be used to verify
           the proxy with when using an HTTPS proxy. Can be overridden by the
           GIT_PROXY_SSL_CAINFO environment variable.

       http.emptyAuth
           Attempt authentication without seeking a username or password. This can be used to
           attempt GSS-Negotiate authentication without specifying a username in the URL, as
           libcurl normally requires a username for authentication.

       http.delegation
           Control GSSAPI credential delegation. The delegation is disabled by default in libcurl
           since version 7.21.7. Set parameter to tell the server what it is allowed to delegate
           when it comes to user credentials. Used with GSS/kerberos. Possible values are:

           •   none - Don’t allow any delegation.

           •   policy - Delegates if and only if the OK-AS-DELEGATE flag is set in the Kerberos
               service ticket, which is a matter of realm policy.

           •   always - Unconditionally allow the server to delegate.

       http.extraHeader
           Pass an additional HTTP header when communicating with a server. If more than one such
           entry exists, all of them are added as extra headers. To allow overriding the settings
           inherited from the system config, an empty value will reset the extra headers to the
           empty list.

       http.cookieFile
           The pathname of a file containing previously stored cookie lines, which should be used
           in the Git http session, if they match the server. The file format of the file to read
           cookies from should be plain HTTP headers or the Netscape/Mozilla cookie file format
           (see curl(1)). NOTE that the file specified with http.cookieFile is used only as input
           unless http.saveCookies is set.

       http.saveCookies
           If set, store cookies received during requests to the file specified by
           http.cookieFile. Has no effect if http.cookieFile is unset.

       http.version
           Use the specified HTTP protocol version when communicating with a server. If you want
           to force the default. The available and default version depend on libcurl. Currently
           the possible values of this option are:

           •   HTTP/2

           •   HTTP/1.1

       http.curloptResolve
           Hostname resolution information that will be used first by libcurl when sending HTTP
           requests. This information should be in one of the following formats:

           •   [+]HOST:PORT:ADDRESS[,ADDRESS]

           •   -HOST:PORT

           The first format redirects all requests to the given HOST:PORT to the provided
           ADDRESS(s). The second format clears all previous config values for that HOST:PORT
           combination. To allow easy overriding of all the settings inherited from the system
           config, an empty value will reset all resolution information to the empty list.

       http.sslVersion
           The SSL version to use when negotiating an SSL connection, if you want to force the
           default. The available and default version depend on whether libcurl was built against
           NSS or OpenSSL and the particular configuration of the crypto library in use.
           Internally this sets the CURLOPT_SSL_VERSION option; see the libcurl documentation for
           more details on the format of this option and for the ssl version supported. Currently
           the possible values of this option are:

           •   sslv2

           •   sslv3

           •   tlsv1

           •   tlsv1.0

           •   tlsv1.1

           •   tlsv1.2

           •   tlsv1.3

           Can be overridden by the GIT_SSL_VERSION environment variable. To force git to use
           libcurl’s default ssl version and ignore any explicit http.sslversion option, set
           GIT_SSL_VERSION to the empty string.

       http.sslCipherList
           A list of SSL ciphers to use when negotiating an SSL connection. The available ciphers
           depend on whether libcurl was built against NSS or OpenSSL and the particular
           configuration of the crypto library in use. Internally this sets the
           CURLOPT_SSL_CIPHER_LIST option; see the libcurl documentation for more details on the
           format of this list.

           Can be overridden by the GIT_SSL_CIPHER_LIST environment variable. To force git to use
           libcurl’s default cipher list and ignore any explicit http.sslCipherList option, set
           GIT_SSL_CIPHER_LIST to the empty string.

       http.sslVerify
           Whether to verify the SSL certificate when fetching or pushing over HTTPS. Defaults to
           true. Can be overridden by the GIT_SSL_NO_VERIFY environment variable.

       http.sslCert
           File containing the SSL certificate when fetching or pushing over HTTPS. Can be
           overridden by the GIT_SSL_CERT environment variable.

       http.sslKey
           File containing the SSL private key when fetching or pushing over HTTPS. Can be
           overridden by the GIT_SSL_KEY environment variable.

       http.sslCertPasswordProtected
           Enable Git’s password prompt for the SSL certificate. Otherwise OpenSSL will prompt
           the user, possibly many times, if the certificate or private key is encrypted. Can be
           overridden by the GIT_SSL_CERT_PASSWORD_PROTECTED environment variable.

       http.sslCAInfo
           File containing the certificates to verify the peer with when fetching or pushing over
           HTTPS. Can be overridden by the GIT_SSL_CAINFO environment variable.

       http.sslCAPath
           Path containing files with the CA certificates to verify the peer with when fetching
           or pushing over HTTPS. Can be overridden by the GIT_SSL_CAPATH environment variable.

       http.sslBackend
           Name of the SSL backend to use (e.g. "openssl" or "schannel"). This option is ignored
           if cURL lacks support for choosing the SSL backend at runtime.

       http.schannelCheckRevoke
           Used to enforce or disable certificate revocation checks in cURL when http.sslBackend
           is set to "schannel". Defaults to true if unset. Only necessary to disable this if Git
           consistently errors and the message is about checking the revocation status of a
           certificate. This option is ignored if cURL lacks support for setting the relevant SSL
           option at runtime.

       http.schannelUseSSLCAInfo
           As of cURL v7.60.0, the Secure Channel backend can use the certificate bundle provided
           via http.sslCAInfo, but that would override the Windows Certificate Store. Since this
           is not desirable by default, Git will tell cURL not to use that bundle by default when
           the schannel backend was configured via http.sslBackend, unless
           http.schannelUseSSLCAInfo overrides this behavior.

       http.pinnedPubkey
           Public key of the https service. It may either be the filename of a PEM or DER encoded
           public key file or a string starting with sha256// followed by the base64 encoded
           sha256 hash of the public key. See also libcurl CURLOPT_PINNEDPUBLICKEY. git will exit
           with an error if this option is set but not supported by cURL.

       http.sslTry
           Attempt to use AUTH SSL/TLS and encrypted data transfers when connecting via regular
           FTP protocol. This might be needed if the FTP server requires it for security reasons
           or you wish to connect securely whenever remote FTP server supports it. Default is
           false since it might trigger certificate verification errors on misconfigured servers.

       http.maxRequests
           How many HTTP requests to launch in parallel. Can be overridden by the
           GIT_HTTP_MAX_REQUESTS environment variable. Default is 5.

       http.minSessions
           The number of curl sessions (counted across slots) to be kept across requests. They
           will not be ended with curl_easy_cleanup() until http_cleanup() is invoked. If
           USE_CURL_MULTI is not defined, this value will be capped at 1. Defaults to 1.

       http.postBuffer
           Maximum size in bytes of the buffer used by smart HTTP transports when POSTing data to
           the remote system. For requests larger than this buffer size, HTTP/1.1 and
           Transfer-Encoding: chunked is used to avoid creating a massive pack file locally.
           Default is 1 MiB, which is sufficient for most requests.

           Note that raising this limit is only effective for disabling chunked transfer encoding
           and therefore should be used only where the remote server or a proxy only supports
           HTTP/1.0 or is noncompliant with the HTTP standard. Raising this is not, in general,
           an effective solution for most push problems, but can increase memory consumption
           significantly since the entire buffer is allocated even for small pushes.

       http.lowSpeedLimit, http.lowSpeedTime
           If the HTTP transfer speed, in bytes per second, is less than http.lowSpeedLimit for
           longer than http.lowSpeedTime seconds, the transfer is aborted. Can be overridden by
           the GIT_HTTP_LOW_SPEED_LIMIT and GIT_HTTP_LOW_SPEED_TIME environment variables.

       http.noEPSV
           A boolean which disables using of EPSV ftp command by curl. This can be helpful with
           some "poor" ftp servers which don’t support EPSV mode. Can be overridden by the
           GIT_CURL_FTP_NO_EPSV environment variable. Default is false (curl will use EPSV).

       http.userAgent
           The HTTP USER_AGENT string presented to an HTTP server. The default value represents
           the version of the Git client such as git/1.7.1. This option allows you to override
           this value to a more common value such as Mozilla/4.0. This may be necessary, for
           instance, if connecting through a firewall that restricts HTTP connections to a set of
           common USER_AGENT strings (but not including those like git/1.7.1). Can be overridden
           by the GIT_HTTP_USER_AGENT environment variable.

       http.followRedirects
           Whether git should follow HTTP redirects. If set to true, git will transparently
           follow any redirect issued by a server it encounters. If set to false, git will treat
           all redirects as errors. If set to initial, git will follow redirects only for the
           initial request to a remote, but not for subsequent follow-up HTTP requests. Since git
           uses the redirected URL as the base for the follow-up requests, this is generally
           sufficient. The default is initial.

       http.<url>.*
           Any of the http.* options above can be applied selectively to some URLs. For a config
           key to match a URL, each element of the config key is compared to that of the URL, in
           the following order:

            1. Scheme (e.g., https in https://example.com/). This field must match exactly
               between the config key and the URL.

            2. Host/domain name (e.g., example.com in https://example.com/). This field must
               match between the config key and the URL. It is possible to specify a * as part of
               the host name to match all subdomains at this level.  https://*.example.com/ for
               example would match https://foo.example.com/, but not
               https://foo.bar.example.com/.

            3. Port number (e.g., 8080 in http://example.com:8080/). This field must match
               exactly between the config key and the URL. Omitted port numbers are automatically
               converted to the correct default for the scheme before matching.

            4. Path (e.g., repo.git in https://example.com/repo.git). The path field of the
               config key must match the path field of the URL either exactly or as a prefix of
               slash-delimited path elements. This means a config key with path foo/ matches URL
               path foo/bar. A prefix can only match on a slash (/) boundary. Longer matches take
               precedence (so a config key with path foo/bar is a better match to URL path
               foo/bar than a config key with just path foo/).

            5. User name (e.g., user in https://user@example.com/repo.git). If the config key has
               a user name it must match the user name in the URL exactly. If the config key does
               not have a user name, that config key will match a URL with any user name
               (including none), but at a lower precedence than a config key with a user name.

           The list above is ordered by decreasing precedence; a URL that matches a config key’s
           path is preferred to one that matches its user name. For example, if the URL is
           https://user@example.com/foo/bar a config key match of https://example.com/foo will be
           preferred over a config key match of https://user@example.com.

           All URLs are normalized before attempting any matching (the password part, if embedded
           in the URL, is always ignored for matching purposes) so that equivalent URLs that are
           simply spelled differently will match properly. Environment variable settings always
           override any matches. The URLs that are matched against are those given directly to
           Git commands. This means any URLs visited as a result of a redirection do not
           participate in matching.

       i18n.commitEncoding
           Character encoding the commit messages are stored in; Git itself does not care per se,
           but this information is necessary e.g. when importing commits from emails or in the
           gitk graphical history browser (and possibly in other places in the future or in other
           porcelains). See e.g.  git-mailinfo(1). Defaults to utf-8.

       i18n.logOutputEncoding
           Character encoding the commit messages are converted to when running git log and
           friends.

       imap.folder
           The folder to drop the mails into, which is typically the Drafts folder. For example:
           "INBOX.Drafts", "INBOX/Drafts" or "[Gmail]/Drafts". Required.

       imap.tunnel
           Command used to set up a tunnel to the IMAP server through which commands will be
           piped instead of using a direct network connection to the server. Required when
           imap.host is not set.

       imap.host
           A URL identifying the server. Use an imap:// prefix for non-secure connections and an
           imaps:// prefix for secure connections. Ignored when imap.tunnel is set, but required
           otherwise.

       imap.user
           The username to use when logging in to the server.

       imap.pass
           The password to use when logging in to the server.

       imap.port
           An integer port number to connect to on the server. Defaults to 143 for imap:// hosts
           and 993 for imaps:// hosts. Ignored when imap.tunnel is set.

       imap.sslverify
           A boolean to enable/disable verification of the server certificate used by the SSL/TLS
           connection. Default is true. Ignored when imap.tunnel is set.

       imap.preformattedHTML
           A boolean to enable/disable the use of html encoding when sending a patch. An html
           encoded patch will be bracketed with <pre> and have a content type of text/html.
           Ironically, enabling this option causes Thunderbird to send the patch as a plain/text,
           format=fixed email. Default is false.

       imap.authMethod
           Specify the authentication method for authenticating with the IMAP server. If Git was
           built with the NO_CURL option, or if your curl version is older than 7.34.0, or if
           you’re running git-imap-send with the --no-curl option, the only supported method is
           CRAM-MD5. If this is not set then git imap-send uses the basic IMAP plaintext LOGIN
           command.

       include.path, includeIf.<condition>.path
           Special variables to include other configuration files. See the "CONFIGURATION FILE"
           section in the main git-config(1) documentation, specifically the "Includes" and
           "Conditional Includes" subsections.

       index.recordEndOfIndexEntries
           Specifies whether the index file should include an "End Of Index Entry" section. This
           reduces index load time on multiprocessor machines but produces a message "ignoring
           EOIE extension" when reading the index using Git versions before 2.20. Defaults to
           true if index.threads has been explicitly enabled, false otherwise.

       index.recordOffsetTable
           Specifies whether the index file should include an "Index Entry Offset Table" section.
           This reduces index load time on multiprocessor machines but produces a message
           "ignoring IEOT extension" when reading the index using Git versions before 2.20.
           Defaults to true if index.threads has been explicitly enabled, false otherwise.

       index.sparse
           When enabled, write the index using sparse-directory entries. This has no effect
           unless core.sparseCheckout and core.sparseCheckoutCone are both enabled. Defaults to
           false.

       index.threads
           Specifies the number of threads to spawn when loading the index. This is meant to
           reduce index load time on multiprocessor machines. Specifying 0 or true will cause Git
           to auto-detect the number of CPUs and set the number of threads accordingly.
           Specifying 1 or false will disable multithreading. Defaults to true.

       index.version
           Specify the version with which new index files should be initialized. This does not
           affect existing repositories. If feature.manyFiles is enabled, then the default is 4.

       index.skipHash
           When enabled, do not compute the trailing hash for the index file. This accelerates
           Git commands that manipulate the index, such as git add, git commit, or git status.
           Instead of storing the checksum, write a trailing set of bytes with value zero,
           indicating that the computation was skipped.

           If you enable index.skipHash, then Git clients older than 2.13.0 will refuse to parse
           the index and Git clients older than 2.40.0 will report an error during git fsck.

       init.templateDir
           Specify the directory from which templates will be copied. (See the "TEMPLATE
           DIRECTORY" section of git-init(1).)

       init.defaultBranch
           Allows overriding the default branch name e.g. when initializing a new repository.

       instaweb.browser
           Specify the program that will be used to browse your working repository in gitweb. See
           git-instaweb(1).

       instaweb.httpd
           The HTTP daemon command-line to start gitweb on your working repository. See git-
           instaweb(1).

       instaweb.local
           If true the web server started by git-instaweb(1) will be bound to the local IP
           (127.0.0.1).

       instaweb.modulePath
           The default module path for git-instaweb(1) to use instead of
           /usr/lib/apache2/modules. Only used if httpd is Apache.

       instaweb.port
           The port number to bind the gitweb httpd to. See git-instaweb(1).

       interactive.singleKey
           In interactive commands, allow the user to provide one-letter input with a single key
           (i.e., without hitting enter). Currently this is used by the --patch mode of git-
           add(1), git-checkout(1), git-restore(1), git-commit(1), git-reset(1), and git-
           stash(1).

       interactive.diffFilter
           When an interactive command (such as git add --patch) shows a colorized diff, git will
           pipe the diff through the shell command defined by this configuration variable. The
           command may mark up the diff further for human consumption, provided that it retains a
           one-to-one correspondence with the lines in the original diff. Defaults to disabled
           (no filtering).

       log.abbrevCommit
           If true, makes git-log(1), git-show(1), and git-whatchanged(1) assume --abbrev-commit.
           You may override this option with --no-abbrev-commit.

       log.date
           Set the default date-time mode for the log command. Setting a value for log.date is
           similar to using git log's --date option. See git-log(1) for details.

           If the format is set to "auto:foo" and the pager is in use, format "foo" will be used
           for the date format. Otherwise, "default" will be used.

       log.decorate
           Print out the ref names of any commits that are shown by the log command. If short is
           specified, the ref name prefixes refs/heads/, refs/tags/ and refs/remotes/ will not be
           printed. If full is specified, the full ref name (including prefix) will be printed.
           If auto is specified, then if the output is going to a terminal, the ref names are
           shown as if short were given, otherwise no ref names are shown. This is the same as
           the --decorate option of the git log.

       log.initialDecorationSet
           By default, git log only shows decorations for certain known ref namespaces. If all is
           specified, then show all refs as decorations.

       log.excludeDecoration
           Exclude the specified patterns from the log decorations. This is similar to the
           --decorate-refs-exclude command-line option, but the config option can be overridden
           by the --decorate-refs option.

       log.diffMerges
           Set diff format to be used when --diff-merges=on is specified, see --diff-merges in
           git-log(1) for details. Defaults to separate.

       log.follow
           If true, git log will act as if the --follow option was used when a single <path> is
           given. This has the same limitations as --follow, i.e. it cannot be used to follow
           multiple files and does not work well on non-linear history.

       log.graphColors
           A list of colors, separated by commas, that can be used to draw history lines in git
           log --graph.

       log.showRoot
           If true, the initial commit will be shown as a big creation event. This is equivalent
           to a diff against an empty tree. Tools like git-log(1) or git-whatchanged(1), which
           normally hide the root commit will now show it. True by default.

       log.showSignature
           If true, makes git-log(1), git-show(1), and git-whatchanged(1) assume
           --show-signature.

       log.mailmap
           If true, makes git-log(1), git-show(1), and git-whatchanged(1) assume --use-mailmap,
           otherwise assume --no-use-mailmap. True by default.

       lsrefs.unborn
           May be "advertise" (the default), "allow", or "ignore". If "advertise", the server
           will respond to the client sending "unborn" (as described in gitprotocol-v2(5)) and
           will advertise support for this feature during the protocol v2 capability
           advertisement. "allow" is the same as "advertise" except that the server will not
           advertise support for this feature; this is useful for load-balanced servers that
           cannot be updated atomically (for example), since the administrator could configure
           "allow", then after a delay, configure "advertise".

       mailinfo.scissors
           If true, makes git-mailinfo(1) (and therefore git-am(1)) act by default as if the
           --scissors option was provided on the command-line. When active, this feature removes
           everything from the message body before a scissors line (i.e. consisting mainly of
           ">8", "8<" and "-").

       mailmap.file
           The location of an augmenting mailmap file. The default mailmap, located in the root
           of the repository, is loaded first, then the mailmap file pointed to by this variable.
           The location of the mailmap file may be in a repository subdirectory, or somewhere
           outside of the repository itself. See git-shortlog(1) and git-blame(1).

       mailmap.blob
           Like mailmap.file, but consider the value as a reference to a blob in the repository.
           If both mailmap.file and mailmap.blob are given, both are parsed, with entries from
           mailmap.file taking precedence. In a bare repository, this defaults to HEAD:.mailmap.
           In a non-bare repository, it defaults to empty.

       maintenance.auto
           This boolean config option controls whether some commands run git maintenance run
           --auto after doing their normal work. Defaults to true.

       maintenance.strategy
           This string config option provides a way to specify one of a few recommended schedules
           for background maintenance. This only affects which tasks are run during git
           maintenance run --schedule=X commands, provided no --task=<task> arguments are
           provided. Further, if a maintenance.<task>.schedule config value is set, then that
           value is used instead of the one provided by maintenance.strategy. The possible
           strategy strings are:

           •   none: This default setting implies no tasks are run at any schedule.

           •   incremental: This setting optimizes for performing small maintenance activities
               that do not delete any data. This does not schedule the gc task, but runs the
               prefetch and commit-graph tasks hourly, the loose-objects and incremental-repack
               tasks daily, and the pack-refs task weekly.

       maintenance.<task>.enabled
           This boolean config option controls whether the maintenance task with name <task> is
           run when no --task option is specified to git maintenance run. These config values are
           ignored if a --task option exists. By default, only maintenance.gc.enabled is true.

       maintenance.<task>.schedule
           This config option controls whether or not the given <task> runs during a git
           maintenance run --schedule=<frequency> command. The value must be one of "hourly",
           "daily", or "weekly".

       maintenance.commit-graph.auto
           This integer config option controls how often the commit-graph task should be run as
           part of git maintenance run --auto. If zero, then the commit-graph task will not run
           with the --auto option. A negative value will force the task to run every time.
           Otherwise, a positive value implies the command should run when the number of
           reachable commits that are not in the commit-graph file is at least the value of
           maintenance.commit-graph.auto. The default value is 100.

       maintenance.loose-objects.auto
           This integer config option controls how often the loose-objects task should be run as
           part of git maintenance run --auto. If zero, then the loose-objects task will not run
           with the --auto option. A negative value will force the task to run every time.
           Otherwise, a positive value implies the command should run when the number of loose
           objects is at least the value of maintenance.loose-objects.auto. The default value is
           100.

       maintenance.incremental-repack.auto
           This integer config option controls how often the incremental-repack task should be
           run as part of git maintenance run --auto. If zero, then the incremental-repack task
           will not run with the --auto option. A negative value will force the task to run every
           time. Otherwise, a positive value implies the command should run when the number of
           pack-files not in the multi-pack-index is at least the value of
           maintenance.incremental-repack.auto. The default value is 10.

       man.viewer
           Specify the programs that may be used to display help in the man format. See git-
           help(1).

       man.<tool>.cmd
           Specify the command to invoke the specified man viewer. The specified command is
           evaluated in shell with the man page passed as an argument. (See git-help(1).)

       man.<tool>.path
           Override the path for the given tool that may be used to display help in the man
           format. See git-help(1).

       merge.conflictStyle
           Specify the style in which conflicted hunks are written out to working tree files upon
           merge. The default is "merge", which shows a <<<<<<< conflict marker, changes made by
           one side, a ======= marker, changes made by the other side, and then a >>>>>>> marker.
           An alternate style, "diff3", adds a ||||||| marker and the original text before the
           ======= marker. The "merge" style tends to produce smaller conflict regions than
           diff3, both because of the exclusion of the original text, and because when a subset
           of lines match on the two sides, they are just pulled out of the conflict region.
           Another alternate style, "zdiff3", is similar to diff3 but removes matching lines on
           the two sides from the conflict region when those matching lines appear near either
           the beginning or end of a conflict region.

       merge.defaultToUpstream
           If merge is called without any commit argument, merge the upstream branches configured
           for the current branch by using their last observed values stored in their
           remote-tracking branches. The values of the branch.<current branch>.merge that name
           the branches at the remote named by branch.<current branch>.remote are consulted, and
           then they are mapped via remote.<remote>.fetch to their corresponding remote-tracking
           branches, and the tips of these tracking branches are merged. Defaults to true.

       merge.ff
           By default, Git does not create an extra merge commit when merging a commit that is a
           descendant of the current commit. Instead, the tip of the current branch is
           fast-forwarded. When set to false, this variable tells Git to create an extra merge
           commit in such a case (equivalent to giving the --no-ff option from the command line).
           When set to only, only such fast-forward merges are allowed (equivalent to giving the
           --ff-only option from the command line).

       merge.verifySignatures
           If true, this is equivalent to the --verify-signatures command line option. See git-
           merge(1) for details.

       merge.branchdesc
           In addition to branch names, populate the log message with the branch description text
           associated with them. Defaults to false.

       merge.log
           In addition to branch names, populate the log message with at most the specified
           number of one-line descriptions from the actual commits that are being merged.
           Defaults to false, and true is a synonym for 20.

       merge.suppressDest
           By adding a glob that matches the names of integration branches to this multi-valued
           configuration variable, the default merge message computed for merges into these
           integration branches will omit "into <branch name>" from its title.

           An element with an empty value can be used to clear the list of globs accumulated from
           previous configuration entries. When there is no merge.suppressDest variable defined,
           the default value of master is used for backward compatibility.

       merge.renameLimit
           The number of files to consider in the exhaustive portion of rename detection during a
           merge. If not specified, defaults to the value of diff.renameLimit. If neither
           merge.renameLimit nor diff.renameLimit are specified, currently defaults to 7000. This
           setting has no effect if rename detection is turned off.

       merge.renames
           Whether Git detects renames. If set to "false", rename detection is disabled. If set
           to "true", basic rename detection is enabled. Defaults to the value of diff.renames.

       merge.directoryRenames
           Whether Git detects directory renames, affecting what happens at merge time to new
           files added to a directory on one side of history when that directory was renamed on
           the other side of history. If merge.directoryRenames is set to "false", directory
           rename detection is disabled, meaning that such new files will be left behind in the
           old directory. If set to "true", directory rename detection is enabled, meaning that
           such new files will be moved into the new directory. If set to "conflict", a conflict
           will be reported for such paths. If merge.renames is false, merge.directoryRenames is
           ignored and treated as false. Defaults to "conflict".

       merge.renormalize
           Tell Git that canonical representation of files in the repository has changed over
           time (e.g. earlier commits record text files with CRLF line endings, but recent ones
           use LF line endings). In such a repository, Git can convert the data recorded in
           commits to a canonical form before performing a merge to reduce unnecessary conflicts.
           For more information, see section "Merging branches with differing checkin/checkout
           attributes" in gitattributes(5).

       merge.stat
           Whether to print the diffstat between ORIG_HEAD and the merge result at the end of the
           merge. True by default.

       merge.autoStash
           When set to true, automatically create a temporary stash entry before the operation
           begins, and apply it after the operation ends. This means that you can run merge on a
           dirty worktree. However, use with care: the final stash application after a successful
           merge might result in non-trivial conflicts. This option can be overridden by the
           --no-autostash and --autostash options of git-merge(1). Defaults to false.

       merge.tool
           Controls which merge tool is used by git-mergetool(1). The list below shows the valid
           built-in values. Any other value is treated as a custom merge tool and requires that a
           corresponding mergetool.<tool>.cmd variable is defined.

       merge.guitool
           Controls which merge tool is used by git-mergetool(1) when the -g/--gui flag is
           specified. The list below shows the valid built-in values. Any other value is treated
           as a custom merge tool and requires that a corresponding mergetool.<guitool>.cmd
           variable is defined.

       merge.verbosity
           Controls the amount of output shown by the recursive merge strategy. Level 0 outputs
           nothing except a final error message if conflicts were detected. Level 1 outputs only
           conflicts, 2 outputs conflicts and file changes. Level 5 and above outputs debugging
           information. The default is level 2. Can be overridden by the GIT_MERGE_VERBOSITY
           environment variable.

       merge.<driver>.name
           Defines a human-readable name for a custom low-level merge driver. See
           gitattributes(5) for details.

       merge.<driver>.driver
           Defines the command that implements a custom low-level merge driver. See
           gitattributes(5) for details.

       merge.<driver>.recursive
           Names a low-level merge driver to be used when performing an internal merge between
           common ancestors. See gitattributes(5) for details.

       mergetool.<tool>.path
           Override the path for the given tool. This is useful in case your tool is not in the
           PATH.

       mergetool.<tool>.cmd
           Specify the command to invoke the specified merge tool. The specified command is
           evaluated in shell with the following variables available: BASE is the name of a
           temporary file containing the common base of the files to be merged, if available;
           LOCAL is the name of a temporary file containing the contents of the file on the
           current branch; REMOTE is the name of a temporary file containing the contents of the
           file from the branch being merged; MERGED contains the name of the file to which the
           merge tool should write the results of a successful merge.

       mergetool.<tool>.hideResolved
           Allows the user to override the global mergetool.hideResolved value for a specific
           tool. See mergetool.hideResolved for the full description.

       mergetool.<tool>.trustExitCode
           For a custom merge command, specify whether the exit code of the merge command can be
           used to determine whether the merge was successful. If this is not set to true then
           the merge target file timestamp is checked, and the merge is assumed to have been
           successful if the file has been updated; otherwise, the user is prompted to indicate
           the success of the merge.

       mergetool.meld.hasOutput
           Older versions of meld do not support the --output option. Git will attempt to detect
           whether meld supports --output by inspecting the output of meld --help. Configuring
           mergetool.meld.hasOutput will make Git skip these checks and use the configured value
           instead. Setting mergetool.meld.hasOutput to true tells Git to unconditionally use the
           --output option, and false avoids using --output.

       mergetool.meld.useAutoMerge
           When the --auto-merge is given, meld will merge all non-conflicting parts
           automatically, highlight the conflicting parts, and wait for user decision. Setting
           mergetool.meld.useAutoMerge to true tells Git to unconditionally use the --auto-merge
           option with meld. Setting this value to auto makes git detect whether --auto-merge is
           supported and will only use --auto-merge when available. A value of false avoids using
           --auto-merge altogether, and is the default value.

       mergetool.<vimdiff variant>.layout
           Configure the split window layout for vimdiff’s <variant>, which is any of vimdiff,
           nvimdiff, gvimdiff. Upon launching git mergetool with --tool=<variant> (or without
           --tool if merge.tool is configured as <variant>), Git will consult
           mergetool.<variant>.layout to determine the tool’s layout. If the variant-specific
           configuration is not available, vimdiff's is used as fallback. If that too is not
           available, a default layout with 4 windows will be used. To configure the layout, see
           the BACKEND SPECIFIC HINTS section in git-mergetool(1).

       mergetool.hideResolved
           During a merge, Git will automatically resolve as many conflicts as possible and write
           the MERGED file containing conflict markers around any conflicts that it cannot
           resolve; LOCAL and REMOTE normally represent the versions of the file from before
           Git’s conflict resolution. This flag causes LOCAL and REMOTE to be overwritten so that
           only the unresolved conflicts are presented to the merge tool. Can be configured
           per-tool via the mergetool.<tool>.hideResolved configuration variable. Defaults to
           false.

       mergetool.keepBackup
           After performing a merge, the original file with conflict markers can be saved as a
           file with a .orig extension. If this variable is set to false then this file is not
           preserved. Defaults to true (i.e. keep the backup files).

       mergetool.keepTemporaries
           When invoking a custom merge tool, Git uses a set of temporary files to pass to the
           tool. If the tool returns an error and this variable is set to true, then these
           temporary files will be preserved; otherwise, they will be removed after the tool has
           exited. Defaults to false.

       mergetool.writeToTemp
           Git writes temporary BASE, LOCAL, and REMOTE versions of conflicting files in the
           worktree by default. Git will attempt to use a temporary directory for these files
           when set true. Defaults to false.

       mergetool.prompt
           Prompt before each invocation of the merge resolution program.

       mergetool.guiDefault
           Set true to use the merge.guitool by default (equivalent to specifying the --gui
           argument), or auto to select merge.guitool or merge.tool depending on the presence of
           a DISPLAY environment variable value. The default is false, where the --gui argument
           must be provided explicitly for the merge.guitool to be used.

       notes.mergeStrategy
           Which merge strategy to choose by default when resolving notes conflicts. Must be one
           of manual, ours, theirs, union, or cat_sort_uniq. Defaults to manual. See the "NOTES
           MERGE STRATEGIES" section of git-notes(1) for more information on each strategy.

           This setting can be overridden by passing the --strategy option to git-notes(1).

       notes.<name>.mergeStrategy
           Which merge strategy to choose when doing a notes merge into refs/notes/<name>. This
           overrides the more general "notes.mergeStrategy". See the "NOTES MERGE STRATEGIES"
           section in git-notes(1) for more information on the available strategies.

       notes.displayRef
           Which ref (or refs, if a glob or specified more than once), in addition to the default
           set by core.notesRef or GIT_NOTES_REF, to read notes from when showing commit messages
           with the git log family of commands.

           This setting can be overridden with the GIT_NOTES_DISPLAY_REF environment variable,
           which must be a colon separated list of refs or globs.

           A warning will be issued for refs that do not exist, but a glob that does not match
           any refs is silently ignored.

           This setting can be disabled by the --no-notes option to the git log family of
           commands, or by the --notes=<ref> option accepted by those commands.

           The effective value of "core.notesRef" (possibly overridden by GIT_NOTES_REF) is also
           implicitly added to the list of refs to be displayed.

       notes.rewrite.<command>
           When rewriting commits with <command> (currently amend or rebase), if this variable is
           false, git will not copy notes from the original to the rewritten commit. Defaults to
           true. See also "notes.rewriteRef" below.

           This setting can be overridden with the GIT_NOTES_REWRITE_REF environment variable,
           which must be a colon separated list of refs or globs.

       notes.rewriteMode
           When copying notes during a rewrite (see the "notes.rewrite.<command>" option),
           determines what to do if the target commit already has a note. Must be one of
           overwrite, concatenate, cat_sort_uniq, or ignore. Defaults to concatenate.

           This setting can be overridden with the GIT_NOTES_REWRITE_MODE environment variable.

       notes.rewriteRef
           When copying notes during a rewrite, specifies the (fully qualified) ref whose notes
           should be copied. May be a glob, in which case notes in all matching refs will be
           copied. You may also specify this configuration several times.

           Does not have a default value; you must configure this variable to enable note
           rewriting. Set it to refs/notes/commits to enable rewriting for the default commit
           notes.

           Can be overridden with the GIT_NOTES_REWRITE_REF environment variable. See
           notes.rewrite.<command> above for a further description of its format.

       pack.window
           The size of the window used by git-pack-objects(1) when no window size is given on the
           command line. Defaults to 10.

       pack.depth
           The maximum delta depth used by git-pack-objects(1) when no maximum depth is given on
           the command line. Defaults to 50. Maximum value is 4095.

       pack.windowMemory
           The maximum size of memory that is consumed by each thread in git-pack-objects(1) for
           pack window memory when no limit is given on the command line. The value can be
           suffixed with "k", "m", or "g". When left unconfigured (or set explicitly to 0), there
           will be no limit.

       pack.compression
           An integer -1..9, indicating the compression level for objects in a pack file. -1 is
           the zlib default. 0 means no compression, and 1..9 are various speed/size tradeoffs, 9
           being slowest. If not set, defaults to core.compression. If that is not set, defaults
           to -1, the zlib default, which is "a default compromise between speed and compression
           (currently equivalent to level 6)."

           Note that changing the compression level will not automatically recompress all
           existing objects. You can force recompression by passing the -F option to git-
           repack(1).

       pack.allowPackReuse
           When true or "single", and when reachability bitmaps are enabled, pack-objects will
           try to send parts of the bitmapped packfile verbatim. When "multi", and when a
           multi-pack reachability bitmap is available, pack-objects will try to send parts of
           all packs in the MIDX.

           If only a single pack bitmap is available, and pack.allowPackReuse is set to "multi",
           reuse parts of just the bitmapped packfile. This can reduce memory and CPU usage to
           serve fetches, but might result in sending a slightly larger pack. Defaults to true.

       pack.island
           An extended regular expression configuring a set of delta islands. See "DELTA ISLANDS"
           in git-pack-objects(1) for details.

       pack.islandCore
           Specify an island name which gets to have its objects be packed first. This creates a
           kind of pseudo-pack at the front of one pack, so that the objects from the specified
           island are hopefully faster to copy into any pack that should be served to a user
           requesting these objects. In practice this means that the island specified should
           likely correspond to what is the most commonly cloned in the repo. See also "DELTA
           ISLANDS" in git-pack-objects(1).

       pack.deltaCacheSize
           The maximum memory in bytes used for caching deltas in git-pack-objects(1) before
           writing them out to a pack. This cache is used to speed up the writing object phase by
           not having to recompute the final delta result once the best match for all objects is
           found. Repacking large repositories on machines which are tight with memory might be
           badly impacted by this though, especially if this cache pushes the system into
           swapping. A value of 0 means no limit. The smallest size of 1 byte may be used to
           virtually disable this cache. Defaults to 256 MiB.

       pack.deltaCacheLimit
           The maximum size of a delta, that is cached in git-pack-objects(1). This cache is used
           to speed up the writing object phase by not having to recompute the final delta result
           once the best match for all objects is found. Defaults to 1000. Maximum value is
           65535.

       pack.threads
           Specifies the number of threads to spawn when searching for best delta matches. This
           requires that git-pack-objects(1) be compiled with pthreads otherwise this option is
           ignored with a warning. This is meant to reduce packing time on multiprocessor
           machines. The required amount of memory for the delta search window is however
           multiplied by the number of threads. Specifying 0 will cause Git to auto-detect the
           number of CPUs and set the number of threads accordingly.

       pack.indexVersion
           Specify the default pack index version. Valid values are 1 for legacy pack index used
           by Git versions prior to 1.5.2, and 2 for the new pack index with capabilities for
           packs larger than 4 GB as well as proper protection against the repacking of corrupted
           packs. Version 2 is the default. Note that version 2 is enforced and this config
           option is ignored whenever the corresponding pack is larger than 2 GB.

           If you have an old Git that does not understand the version 2 *.idx file, cloning or
           fetching over a non-native protocol (e.g. "http") that will copy both *.pack file and
           corresponding *.idx file from the other side may give you a repository that cannot be
           accessed with your older version of Git. If the *.pack file is smaller than 2 GB,
           however, you can use git-index-pack(1) on the *.pack file to regenerate the *.idx
           file.

       pack.packSizeLimit
           The maximum size of a pack. This setting only affects packing to a file when
           repacking, i.e. the git:// protocol is unaffected. It can be overridden by the
           --max-pack-size option of git-repack(1). Reaching this limit results in the creation
           of multiple packfiles.

           Note that this option is rarely useful, and may result in a larger total on-disk size
           (because Git will not store deltas between packs) and worse runtime performance
           (object lookup within multiple packs is slower than a single pack, and optimizations
           like reachability bitmaps cannot cope with multiple packs).

           If you need to actively run Git using smaller packfiles (e.g., because your filesystem
           does not support large files), this option may help. But if your goal is to transmit a
           packfile over a medium that supports limited sizes (e.g., removable media that cannot
           store the whole repository), you are likely better off creating a single large
           packfile and splitting it using a generic multi-volume archive tool (e.g., Unix
           split).

           The minimum size allowed is limited to 1 MiB. The default is unlimited. Common unit
           suffixes of k, m, or g are supported.

       pack.useBitmaps
           When true, git will use pack bitmaps (if available) when packing to stdout (e.g.,
           during the server side of a fetch). Defaults to true. You should not generally need to
           turn this off unless you are debugging pack bitmaps.

       pack.useBitmapBoundaryTraversal
           When true, Git will use an experimental algorithm for computing reachability queries
           with bitmaps. Instead of building up complete bitmaps for all of the negated tips and
           then OR-ing them together, consider negated tips with existing bitmaps as additive
           (i.e. OR-ing them into the result if they exist, ignoring them otherwise), and build
           up a bitmap at the boundary instead.

           When using this algorithm, Git may include too many objects as a result of not opening
           up trees belonging to certain UNINTERESTING commits. This inexactness matches the
           non-bitmap traversal algorithm.

           In many cases, this can provide a speed-up over the exact algorithm, particularly when
           there is poor bitmap coverage of the negated side of the query.

       pack.useSparse
           When true, git will default to using the --sparse option in git pack-objects when the
           --revs option is present. This algorithm only walks trees that appear in paths that
           introduce new objects. This can have significant performance benefits when computing a
           pack to send a small change. However, it is possible that extra objects are added to
           the pack-file if the included commits contain certain types of direct renames. Default
           is true.

       pack.preferBitmapTips
           When selecting which commits will receive bitmaps, prefer a commit at the tip of any
           reference that is a suffix of any value of this configuration over any other commits
           in the "selection window".

           Note that setting this configuration to refs/foo does not mean that the commits at the
           tips of refs/foo/bar and refs/foo/baz will necessarily be selected. This is because
           commits are selected for bitmaps from within a series of windows of variable length.

           If a commit at the tip of any reference which is a suffix of any value of this
           configuration is seen in a window, it is immediately given preference over any other
           commit in that window.

       pack.writeBitmaps (deprecated)
           This is a deprecated synonym for repack.writeBitmaps.

       pack.writeBitmapHashCache
           When true, git will include a "hash cache" section in the bitmap index (if one is
           written). This cache can be used to feed git’s delta heuristics, potentially leading
           to better deltas between bitmapped and non-bitmapped objects (e.g., when serving a
           fetch between an older, bitmapped pack and objects that have been pushed since the
           last gc). The downside is that it consumes 4 bytes per object of disk space. Defaults
           to true.

           When writing a multi-pack reachability bitmap, no new namehashes are computed;
           instead, any namehashes stored in an existing bitmap are permuted into their
           appropriate location when writing a new bitmap.

       pack.writeBitmapLookupTable
           When true, Git will include a "lookup table" section in the bitmap index (if one is
           written). This table is used to defer loading individual bitmaps as late as possible.
           This can be beneficial in repositories that have relatively large bitmap indexes.
           Defaults to false.

       pack.readReverseIndex
           When true, git will read any .rev file(s) that may be available (see: gitformat-
           pack(5)). When false, the reverse index will be generated from scratch and stored in
           memory. Defaults to true.

       pack.writeReverseIndex
           When true, git will write a corresponding .rev file (see: gitformat-pack(5)) for each
           new packfile that it writes in all places except for git-fast-import(1) and in the
           bulk checkin mechanism. Defaults to true.

       pager.<cmd>
           If the value is boolean, turns on or off pagination of the output of a particular Git
           subcommand when writing to a tty. Otherwise, turns on pagination for the subcommand
           using the pager specified by the value of pager.<cmd>. If --paginate or --no-pager is
           specified on the command line, it takes precedence over this option. To disable
           pagination for all commands, set core.pager or GIT_PAGER to cat.

       pretty.<name>
           Alias for a --pretty= format string, as specified in git-log(1). Any aliases defined
           here can be used just as the built-in pretty formats could. For example, running git
           config pretty.changelog "format:* %H %s" would cause the invocation git log
           --pretty=changelog to be equivalent to running git log "--pretty=format:* %H %s". Note
           that an alias with the same name as a built-in format will be silently ignored.

       protocol.allow
           If set, provide a user defined default policy for all protocols which don’t explicitly
           have a policy (protocol.<name>.allow). By default, if unset, known-safe protocols
           (http, https, git, ssh) have a default policy of always, known-dangerous protocols
           (ext) have a default policy of never, and all other protocols (including file) have a
           default policy of user. Supported policies:

           •   always - protocol is always able to be used.

           •   never - protocol is never able to be used.

           •   user - protocol is only able to be used when GIT_PROTOCOL_FROM_USER is either
               unset or has a value of 1. This policy should be used when you want a protocol to
               be directly usable by the user but don’t want it used by commands which execute
               clone/fetch/push commands without user input, e.g. recursive submodule
               initialization.

       protocol.<name>.allow
           Set a policy to be used by protocol <name> with clone/fetch/push commands. See
           protocol.allow above for the available policies.

           The protocol names currently used by git are:

           •   file: any local file-based path (including file:// URLs, or local paths)

           •   git: the anonymous git protocol over a direct TCP connection (or proxy, if
               configured)

           •   ssh: git over ssh (including host:path syntax, ssh://, etc).

           •   http: git over http, both "smart http" and "dumb http". Note that this does not
               include https; if you want to configure both, you must do so individually.

           •   any external helpers are named by their protocol (e.g., use hg to allow the
               git-remote-hg helper)

       protocol.version
           If set, clients will attempt to communicate with a server using the specified protocol
           version. If the server does not support it, communication falls back to version 0. If
           unset, the default is 2. Supported versions:

           •   0 - the original wire protocol.

           •   1 - the original wire protocol with the addition of a version string in the
               initial response from the server.

           •   2 - Wire protocol version 2, see gitprotocol-v2(5).

       pull.ff
           By default, Git does not create an extra merge commit when merging a commit that is a
           descendant of the current commit. Instead, the tip of the current branch is
           fast-forwarded. When set to false, this variable tells Git to create an extra merge
           commit in such a case (equivalent to giving the --no-ff option from the command line).
           When set to only, only such fast-forward merges are allowed (equivalent to giving the
           --ff-only option from the command line). This setting overrides merge.ff when pulling.

       pull.rebase
           When true, rebase branches on top of the fetched branch, instead of merging the
           default branch from the default remote when "git pull" is run. See
           "branch.<name>.rebase" for setting this on a per-branch basis.

           When merges (or just m), pass the --rebase-merges option to git rebase so that the
           local merge commits are included in the rebase (see git-rebase(1) for details).

           When the value is interactive (or just i), the rebase is run in interactive mode.

           NOTE: this is a possibly dangerous operation; do not use it unless you understand the
           implications (see git-rebase(1) for details).

       pull.octopus
           The default merge strategy to use when pulling multiple branches at once.

       pull.twohead
           The default merge strategy to use when pulling a single branch.

       push.autoSetupRemote
           If set to "true" assume --set-upstream on default push when no upstream tracking
           exists for the current branch; this option takes effect with push.default options
           simple, upstream, and current. It is useful if by default you want new branches to be
           pushed to the default remote (like the behavior of push.default=current) and you also
           want the upstream tracking to be set. Workflows most likely to benefit from this
           option are simple central workflows where all branches are expected to have the same
           name on the remote.

       push.default
           Defines the action git push should take if no refspec is given (whether from the
           command-line, config, or elsewhere). Different values are well-suited for specific
           workflows; for instance, in a purely central workflow (i.e. the fetch source is equal
           to the push destination), upstream is probably what you want. Possible values are:

           •   nothing - do not push anything (error out) unless a refspec is given. This is
               primarily meant for people who want to avoid mistakes by always being explicit.

           •   current - push the current branch to update a branch with the same name on the
               receiving end. Works in both central and non-central workflows.

           •   upstream - push the current branch back to the branch whose changes are usually
               integrated into the current branch (which is called @{upstream}). This mode only
               makes sense if you are pushing to the same repository you would normally pull from
               (i.e. central workflow).

           •   tracking - This is a deprecated synonym for upstream.

           •   simple - push the current branch with the same name on the remote.

               If you are working on a centralized workflow (pushing to the same repository you
               pull from, which is typically origin), then you need to configure an upstream
               branch with the same name.

               This mode is the default since Git 2.0, and is the safest option suited for
               beginners.

           •   matching - push all branches having the same name on both ends. This makes the
               repository you are pushing to remember the set of branches that will be pushed out
               (e.g. if you always push maint and master there and no other branches, the
               repository you push to will have these two branches, and your local maint and
               master will be pushed there).

               To use this mode effectively, you have to make sure all the branches you would
               push out are ready to be pushed out before running git push, as the whole point of
               this mode is to allow you to push all of the branches in one go. If you usually
               finish work on only one branch and push out the result, while other branches are
               unfinished, this mode is not for you. Also this mode is not suitable for pushing
               into a shared central repository, as other people may add new branches there, or
               update the tip of existing branches outside your control.

               This used to be the default, but not since Git 2.0 (simple is the new default).

       push.followTags
           If set to true, enable --follow-tags option by default. You may override this
           configuration at time of push by specifying --no-follow-tags.

       push.gpgSign
           May be set to a boolean value, or the string if-asked. A true value causes all pushes
           to be GPG signed, as if --signed is passed to git-push(1). The string if-asked causes
           pushes to be signed if the server supports it, as if --signed=if-asked is passed to
           git push. A false value may override a value from a lower-priority config file. An
           explicit command-line flag always overrides this config option.

       push.pushOption
           When no --push-option=<option> argument is given from the command line, git push
           behaves as if each <value> of this variable is given as --push-option=<value>.

           This is a multi-valued variable, and an empty value can be used in a higher priority
           configuration file (e.g.  .git/config in a repository) to clear the values inherited
           from a lower priority configuration files (e.g.  $HOME/.gitconfig).

               Example:

               /etc/gitconfig
                 push.pushoption = a
                 push.pushoption = b

               ~/.gitconfig
                 push.pushoption = c

               repo/.git/config
                 push.pushoption =
                 push.pushoption = b

               This will result in only b (a and c are cleared).

       push.recurseSubmodules
           May be "check", "on-demand", "only", or "no", with the same behavior as that of "push
           --recurse-submodules". If not set, no is used by default, unless submodule.recurse is
           set (in which case a true value means on-demand).

       push.useForceIfIncludes
           If set to "true", it is equivalent to specifying --force-if-includes as an option to
           git-push(1) in the command line. Adding --no-force-if-includes at the time of push
           overrides this configuration setting.

       push.negotiate
           If set to "true", attempt to reduce the size of the packfile sent by rounds of
           negotiation in which the client and the server attempt to find commits in common. If
           "false", Git will rely solely on the server’s ref advertisement to find commits in
           common.

       push.useBitmaps
           If set to "false", disable use of bitmaps for "git push" even if pack.useBitmaps is
           "true", without preventing other git operations from using bitmaps. Default is true.

       rebase.backend
           Default backend to use for rebasing. Possible choices are apply or merge. In the
           future, if the merge backend gains all remaining capabilities of the apply backend,
           this setting may become unused.

       rebase.stat
           Whether to show a diffstat of what changed upstream since the last rebase. False by
           default.

       rebase.autoSquash
           If set to true, enable the --autosquash option of git-rebase(1) by default for
           interactive mode. This can be overridden with the --no-autosquash option.

       rebase.autoStash
           When set to true, automatically create a temporary stash entry before the operation
           begins, and apply it after the operation ends. This means that you can run rebase on a
           dirty worktree. However, use with care: the final stash application after a successful
           rebase might result in non-trivial conflicts. This option can be overridden by the
           --no-autostash and --autostash options of git-rebase(1). Defaults to false.

       rebase.updateRefs
           If set to true enable --update-refs option by default.

       rebase.missingCommitsCheck
           If set to "warn", git rebase -i will print a warning if some commits are removed (e.g.
           a line was deleted), however the rebase will still proceed. If set to "error", it will
           print the previous warning and stop the rebase, git rebase --edit-todo can then be
           used to correct the error. If set to "ignore", no checking is done. To drop a commit
           without warning or error, use the drop command in the todo list. Defaults to "ignore".

       rebase.instructionFormat
           A format string, as specified in git-log(1), to be used for the todo list during an
           interactive rebase. The format will automatically have the commit hash prepended to
           the format.

       rebase.abbreviateCommands
           If set to true, git rebase will use abbreviated command names in the todo list
           resulting in something like this:

                       p deadbee The oneline of the commit
                       p fa1afe1 The oneline of the next commit
                       ...

           instead of:

                       pick deadbee The oneline of the commit
                       pick fa1afe1 The oneline of the next commit
                       ...

           Defaults to false.

       rebase.rescheduleFailedExec
           Automatically reschedule exec commands that failed. This only makes sense in
           interactive mode (or when an --exec option was provided). This is the same as
           specifying the --reschedule-failed-exec option.

       rebase.forkPoint
           If set to false set --no-fork-point option by default.

       rebase.rebaseMerges
           Whether and how to set the --rebase-merges option by default. Can be rebase-cousins,
           no-rebase-cousins, or a boolean. Setting to true or to no-rebase-cousins is equivalent
           to --rebase-merges=no-rebase-cousins, setting to rebase-cousins is equivalent to
           --rebase-merges=rebase-cousins, and setting to false is equivalent to
           --no-rebase-merges. Passing --rebase-merges on the command line, with or without an
           argument, overrides any rebase.rebaseMerges configuration.

       rebase.maxLabelLength
           When generating label names from commit subjects, truncate the names to this length.
           By default, the names are truncated to a little less than NAME_MAX (to allow e.g.
           .lock files to be written for the corresponding loose refs).

       receive.advertiseAtomic
           By default, git-receive-pack will advertise the atomic push capability to its clients.
           If you don’t want to advertise this capability, set this variable to false.

       receive.advertisePushOptions
           When set to true, git-receive-pack will advertise the push options capability to its
           clients. False by default.

       receive.autogc
           By default, git-receive-pack will run "git maintenance run --auto" after receiving
           data from git-push and updating refs. You can stop it by setting this variable to
           false.

       receive.certNonceSeed
           By setting this variable to a string, git receive-pack will accept a git push --signed
           and verify it by using a "nonce" protected by HMAC using this string as a secret key.

       receive.certNonceSlop
           When a git push --signed sends a push certificate with a "nonce" that was issued by a
           receive-pack serving the same repository within this many seconds, export the "nonce"
           found in the certificate to GIT_PUSH_CERT_NONCE to the hooks (instead of what the
           receive-pack asked the sending side to include). This may allow writing checks in
           pre-receive and post-receive a bit easier. Instead of checking
           GIT_PUSH_CERT_NONCE_SLOP environment variable that records by how many seconds the
           nonce is stale to decide if they want to accept the certificate, they only can check
           GIT_PUSH_CERT_NONCE_STATUS is OK.

       receive.fsckObjects
           If it is set to true, git-receive-pack will check all received objects. See
           transfer.fsckObjects for what’s checked. Defaults to false. If not set, the value of
           transfer.fsckObjects is used instead.

       receive.fsck.<msg-id>
           Acts like fsck.<msg-id>, but is used by git-receive-pack(1) instead of git-fsck(1).
           See the fsck.<msg-id> documentation for details.

       receive.fsck.skipList
           Acts like fsck.skipList, but is used by git-receive-pack(1) instead of git-fsck(1).
           See the fsck.skipList documentation for details.

       receive.keepAlive
           After receiving the pack from the client, receive-pack may produce no output (if
           --quiet was specified) while processing the pack, causing some networks to drop the
           TCP connection. With this option set, if receive-pack does not transmit any data in
           this phase for receive.keepAlive seconds, it will send a short keepalive packet. The
           default is 5 seconds; set to 0 to disable keepalives entirely.

       receive.unpackLimit
           If the number of objects received in a push is below this limit then the objects will
           be unpacked into loose object files. However if the number of received objects equals
           or exceeds this limit then the received pack will be stored as a pack, after adding
           any missing delta bases. Storing the pack from a push can make the push operation
           complete faster, especially on slow filesystems. If not set, the value of
           transfer.unpackLimit is used instead.

       receive.maxInputSize
           If the size of the incoming pack stream is larger than this limit, then
           git-receive-pack will error out, instead of accepting the pack file. If not set or set
           to 0, then the size is unlimited.

       receive.denyDeletes
           If set to true, git-receive-pack will deny a ref update that deletes the ref. Use this
           to prevent such a ref deletion via a push.

       receive.denyDeleteCurrent
           If set to true, git-receive-pack will deny a ref update that deletes the currently
           checked out branch of a non-bare repository.

       receive.denyCurrentBranch
           If set to true or "refuse", git-receive-pack will deny a ref update to the currently
           checked out branch of a non-bare repository. Such a push is potentially dangerous
           because it brings the HEAD out of sync with the index and working tree. If set to
           "warn", print a warning of such a push to stderr, but allow the push to proceed. If
           set to false or "ignore", allow such pushes with no message. Defaults to "refuse".

           Another option is "updateInstead" which will update the working tree if pushing into
           the current branch. This option is intended for synchronizing working directories when
           one side is not easily accessible via interactive ssh (e.g. a live web site, hence the
           requirement that the working directory be clean). This mode also comes in handy when
           developing inside a VM to test and fix code on different Operating Systems.

           By default, "updateInstead" will refuse the push if the working tree or the index have
           any difference from the HEAD, but the push-to-checkout hook can be used to customize
           this. See githooks(5).

       receive.denyNonFastForwards
           If set to true, git-receive-pack will deny a ref update which is not a fast-forward.
           Use this to prevent such an update via a push, even if that push is forced. This
           configuration variable is set when initializing a shared repository.

       receive.hideRefs
           This variable is the same as transfer.hideRefs, but applies only to receive-pack (and
           so affects pushes, but not fetches). An attempt to update or delete a hidden ref by
           git push is rejected.

       receive.procReceiveRefs
           This is a multi-valued variable that defines reference prefixes to match the commands
           in receive-pack. Commands matching the prefixes will be executed by an external hook
           "proc-receive", instead of the internal execute_commands function. If this variable is
           not defined, the "proc-receive" hook will never be used, and all commands will be
           executed by the internal execute_commands function.

           For example, if this variable is set to "refs/for", pushing to reference such as
           "refs/for/master" will not create or update a reference named "refs/for/master", but
           may create or update a pull request directly by running the hook "proc-receive".

           Optional modifiers can be provided in the beginning of the value to filter commands
           for specific actions: create (a), modify (m), delete (d). A !  can be included in the
           modifiers to negate the reference prefix entry. E.g.:

               git config --system --add receive.procReceiveRefs ad:refs/heads
               git config --system --add receive.procReceiveRefs !:refs/heads

       receive.updateServerInfo
           If set to true, git-receive-pack will run git-update-server-info after receiving data
           from git-push and updating refs.

       receive.shallowUpdate
           If set to true, .git/shallow can be updated when new refs require new shallow roots.
           Otherwise those refs are rejected.

       remote.pushDefault
           The remote to push to by default. Overrides branch.<name>.remote for all branches, and
           is overridden by branch.<name>.pushRemote for specific branches.

       remote.<name>.url
           The URL of a remote repository. See git-fetch(1) or git-push(1).

       remote.<name>.pushurl
           The push URL of a remote repository. See git-push(1).

       remote.<name>.proxy
           For remotes that require curl (http, https and ftp), the URL to the proxy to use for
           that remote. Set to the empty string to disable proxying for that remote.

       remote.<name>.proxyAuthMethod
           For remotes that require curl (http, https and ftp), the method to use for
           authenticating against the proxy in use (probably set in remote.<name>.proxy). See
           http.proxyAuthMethod.

       remote.<name>.fetch
           The default set of "refspec" for git-fetch(1). See git-fetch(1).

       remote.<name>.push
           The default set of "refspec" for git-push(1). See git-push(1).

       remote.<name>.mirror
           If true, pushing to this remote will automatically behave as if the --mirror option
           was given on the command line.

       remote.<name>.skipDefaultUpdate
           If true, this remote will be skipped by default when updating using git-fetch(1) or
           the update subcommand of git-remote(1).

       remote.<name>.skipFetchAll
           If true, this remote will be skipped by default when updating using git-fetch(1) or
           the update subcommand of git-remote(1).

       remote.<name>.receivepack
           The default program to execute on the remote side when pushing. See option
           --receive-pack of git-push(1).

       remote.<name>.uploadpack
           The default program to execute on the remote side when fetching. See option
           --upload-pack of git-fetch-pack(1).

       remote.<name>.tagOpt
           Setting this value to --no-tags disables automatic tag following when fetching from
           remote <name>. Setting it to --tags will fetch every tag from remote <name>, even if
           they are not reachable from remote branch heads. Passing these flags directly to git-
           fetch(1) can override this setting. See options --tags and --no-tags of git-fetch(1).

       remote.<name>.vcs
           Setting this to a value <vcs> will cause Git to interact with the remote with the
           git-remote-<vcs> helper.

       remote.<name>.prune
           When set to true, fetching from this remote by default will also remove any
           remote-tracking references that no longer exist on the remote (as if the --prune
           option was given on the command line). Overrides fetch.prune settings, if any.

       remote.<name>.pruneTags
           When set to true, fetching from this remote by default will also remove any local tags
           that no longer exist on the remote if pruning is activated in general via
           remote.<name>.prune, fetch.prune or --prune. Overrides fetch.pruneTags settings, if
           any.

           See also remote.<name>.prune and the PRUNING section of git-fetch(1).

       remote.<name>.promisor
           When set to true, this remote will be used to fetch promisor objects.

       remote.<name>.partialclonefilter
           The filter that will be applied when fetching from this promisor remote. Changing or
           clearing this value will only affect fetches for new commits. To fetch associated
           objects for commits already present in the local object database, use the --refetch
           option of git-fetch(1).

       remotes.<group>
           The list of remotes which are fetched by "git remote update <group>". See git-
           remote(1).

       repack.useDeltaBaseOffset
           By default, git-repack(1) creates packs that use delta-base offset. If you need to
           share your repository with Git older than version 1.4.4, either directly or via a dumb
           protocol such as http, then you need to set this option to "false" and repack. Access
           from old Git versions over the native protocol are unaffected by this option.

       repack.packKeptObjects
           If set to true, makes git repack act as if --pack-kept-objects was passed. See git-
           repack(1) for details. Defaults to false normally, but true if a bitmap index is being
           written (either via --write-bitmap-index or repack.writeBitmaps).

       repack.useDeltaIslands
           If set to true, makes git repack act as if --delta-islands was passed. Defaults to
           false.

       repack.writeBitmaps
           When true, git will write a bitmap index when packing all objects to disk (e.g., when
           git repack -a is run). This index can speed up the "counting objects" phase of
           subsequent packs created for clones and fetches, at the cost of some disk space and
           extra time spent on the initial repack. This has no effect if multiple packfiles are
           created. Defaults to true on bare repos, false otherwise.

       repack.updateServerInfo
           If set to false, git-repack(1) will not run git-update-server-info(1). Defaults to
           true. Can be overridden when true by the -n option of git-repack(1).

       repack.cruftWindow, repack.cruftWindowMemory, repack.cruftDepth, repack.cruftThreads
           Parameters used by git-pack-objects(1) when generating a cruft pack and the respective
           parameters are not given over the command line. See similarly named pack.*
           configuration variables for defaults and meaning.

       rerere.autoUpdate
           When set to true, git-rerere updates the index with the resulting contents after it
           cleanly resolves conflicts using previously recorded resolutions. Defaults to false.

       rerere.enabled
           Activate recording of resolved conflicts, so that identical conflict hunks can be
           resolved automatically, should they be encountered again. By default, git-rerere(1) is
           enabled if there is an rr-cache directory under the $GIT_DIR, e.g. if "rerere" was
           previously used in the repository.

       revert.reference
           Setting this variable to true makes git revert behave as if the --reference option is
           given.

       safe.bareRepository
           Specifies which bare repositories Git will work with. The currently supported values
           are:

           •   all: Git works with all bare repositories. This is the default.

           •   explicit: Git only works with bare repositories specified via the top-level
               --git-dir command-line option, or the GIT_DIR environment variable (see git(1)).

               If you do not use bare repositories in your workflow, then it may be beneficial to
               set safe.bareRepository to explicit in your global config. This will protect you
               from attacks that involve cloning a repository that contains a bare repository and
               running a Git command within that directory.

               This config setting is only respected in protected configuration (see the section
               called “SCOPES”). This prevents untrusted repositories from tampering with this
               value.

       safe.directory
           These config entries specify Git-tracked directories that are considered safe even if
           they are owned by someone other than the current user. By default, Git will refuse to
           even parse a Git config of a repository owned by someone else, let alone run its
           hooks, and this config setting allows users to specify exceptions, e.g. for
           intentionally shared repositories (see the --shared option in git-init(1)).

           This is a multi-valued setting, i.e. you can add more than one directory via git
           config --add. To reset the list of safe directories (e.g. to override any such
           directories specified in the system config), add a safe.directory entry with an empty
           value.

           This config setting is only respected in protected configuration (see the section
           called “SCOPES”). This prevents untrusted repositories from tampering with this value.

           The value of this setting is interpolated, i.e.  ~/<path> expands to a path relative
           to the home directory and %(prefix)/<path> expands to a path relative to Git’s
           (runtime) prefix.

           To completely opt-out of this security check, set safe.directory to the string *. This
           will allow all repositories to be treated as if their directory was listed in the
           safe.directory list. If safe.directory=* is set in system config and you want to
           re-enable this protection, then initialize your list with an empty value before
           listing the repositories that you deem safe.

           As explained, Git only allows you to access repositories owned by yourself, i.e. the
           user who is running Git, by default. When Git is running as root in a non Windows
           platform that provides sudo, however, git checks the SUDO_UID environment variable
           that sudo creates and will allow access to the uid recorded as its value in addition
           to the id from root. This is to make it easy to perform a common sequence during
           installation "make && sudo make install". A git process running under sudo runs as
           root but the sudo command exports the environment variable to record which id the
           original user has. If that is not what you would prefer and want git to only trust
           repositories that are owned by root instead, then you can remove the SUDO_UID variable
           from root’s environment before invoking git.

       sendemail.identity
           A configuration identity. When given, causes values in the sendemail.<identity>
           subsection to take precedence over values in the sendemail section. The default
           identity is the value of sendemail.identity.

       sendemail.smtpEncryption
           See git-send-email(1) for description. Note that this setting is not subject to the
           identity mechanism.

       sendemail.smtpSSLCertPath
           Path to ca-certificates (either a directory or a single file). Set it to an empty
           string to disable certificate verification.

       sendemail.<identity>.*
           Identity-specific versions of the sendemail.*  parameters found below, taking
           precedence over those when this identity is selected, through either the command-line
           or sendemail.identity.

       sendemail.multiEdit
           If true (default), a single editor instance will be spawned to edit files you have to
           edit (patches when --annotate is used, and the summary when --compose is used). If
           false, files will be edited one after the other, spawning a new editor each time.

       sendemail.confirm
           Sets the default for whether to confirm before sending. Must be one of always, never,
           cc, compose, or auto. See --confirm in the git-send-email(1) documentation for the
           meaning of these values.

       sendemail.aliasesFile
           To avoid typing long email addresses, point this to one or more email aliases files.
           You must also supply sendemail.aliasFileType.

       sendemail.aliasFileType
           Format of the file(s) specified in sendemail.aliasesFile. Must be one of mutt, mailrc,
           pine, elm, gnus, or sendmail.

           What an alias file in each format looks like can be found in the documentation of the
           email program of the same name. The differences and limitations from the standard
           formats are described below:

           sendmail

               •   Quoted aliases and quoted addresses are not supported: lines that contain a "
                   symbol are ignored.

               •   Redirection to a file (/path/name) or pipe (|command) is not supported.

               •   File inclusion (:include: /path/name) is not supported.

               •   Warnings are printed on the standard error output for any explicitly
                   unsupported constructs, and any other lines that are not recognized by the
                   parser.

       sendemail.annotate, sendemail.bcc, sendemail.cc, sendemail.ccCmd, sendemail.chainReplyTo,
       sendemail.envelopeSender, sendemail.from, sendemail.headerCmd, sendemail.signedOffByCc,
       sendemail.smtpPass, sendemail.suppressCc, sendemail.suppressFrom, sendemail.to,
       sendemail.toCmd, sendemail.smtpDomain, sendemail.smtpServer, sendemail.smtpServerPort,
       sendemail.smtpServerOption, sendemail.smtpUser, sendemail.thread,
       sendemail.transferEncoding, sendemail.validate, sendemail.xmailer
           These configuration variables all provide a default for git-send-email(1) command-line
           options. See its documentation for details.

       sendemail.signedOffCc (deprecated)
           Deprecated alias for sendemail.signedOffByCc.

       sendemail.smtpBatchSize
           Number of messages to be sent per connection, after that a relogin will happen. If the
           value is 0 or undefined, send all messages in one connection. See also the
           --batch-size option of git-send-email(1).

       sendemail.smtpReloginDelay
           Seconds to wait before reconnecting to the smtp server. See also the --relogin-delay
           option of git-send-email(1).

       sendemail.forbidSendmailVariables
           To avoid common misconfiguration mistakes, git-send-email(1) will abort with a warning
           if any configuration options for "sendmail" exist. Set this variable to bypass the
           check.

       sequence.editor
           Text editor used by git rebase -i for editing the rebase instruction file. The value
           is meant to be interpreted by the shell when it is used. It can be overridden by the
           GIT_SEQUENCE_EDITOR environment variable. When not configured, the default commit
           message editor is used instead.

       showBranch.default
           The default set of branches for git-show-branch(1). See git-show-branch(1).

       sparse.expectFilesOutsideOfPatterns
           Typically with sparse checkouts, files not matching any sparsity patterns are marked
           with a SKIP_WORKTREE bit in the index and are missing from the working tree.
           Accordingly, Git will ordinarily check whether files with the SKIP_WORKTREE bit are in
           fact present in the working tree contrary to expectations. If Git finds any, it marks
           those paths as present by clearing the relevant SKIP_WORKTREE bits. This option can be
           used to tell Git that such present-despite-skipped files are expected and to stop
           checking for them.

           The default is false, which allows Git to automatically recover from the list of files
           in the index and working tree falling out of sync.

           Set this to true if you are in a setup where some external factor relieves Git of the
           responsibility for maintaining the consistency between the presence of working tree
           files and sparsity patterns. For example, if you have a Git-aware virtual file system
           that has a robust mechanism for keeping the working tree and the sparsity patterns up
           to date based on access patterns.

           Regardless of this setting, Git does not check for present-despite-skipped files
           unless sparse checkout is enabled, so this config option has no effect unless
           core.sparseCheckout is true.

       splitIndex.maxPercentChange
           When the split index feature is used, this specifies the percent of entries the split
           index can contain compared to the total number of entries in both the split index and
           the shared index before a new shared index is written. The value should be between 0
           and 100. If the value is 0, then a new shared index is always written; if it is 100, a
           new shared index is never written. By default, the value is 20, so a new shared index
           is written if the number of entries in the split index would be greater than 20
           percent of the total number of entries. See git-update-index(1).

       splitIndex.sharedIndexExpire
           When the split index feature is used, shared index files that were not modified since
           the time this variable specifies will be removed when a new shared index file is
           created. The value "now" expires all entries immediately, and "never" suppresses
           expiration altogether. The default value is "2.weeks.ago". Note that a shared index
           file is considered modified (for the purpose of expiration) each time a new
           split-index file is either created based on it or read from it. See git-update-
           index(1).

       ssh.variant
           By default, Git determines the command line arguments to use based on the basename of
           the configured SSH command (configured using the environment variable GIT_SSH or
           GIT_SSH_COMMAND or the config setting core.sshCommand). If the basename is
           unrecognized, Git will attempt to detect support of OpenSSH options by first invoking
           the configured SSH command with the -G (print configuration) option and will
           subsequently use OpenSSH options (if that is successful) or no options besides the
           host and remote command (if it fails).

           The config variable ssh.variant can be set to override this detection. Valid values
           are ssh (to use OpenSSH options), plink, putty, tortoiseplink, simple (no options
           except the host and remote command). The default auto-detection can be explicitly
           requested using the value auto. Any other value is treated as ssh. This setting can
           also be overridden via the environment variable GIT_SSH_VARIANT.

           The current command-line parameters used for each variant are as follows:

           •   ssh - [-p port] [-4] [-6] [-o option] [username@]host command

           •   simple - [username@]host command

           •   plink or putty - [-P port] [-4] [-6] [username@]host command

           •   tortoiseplink - [-P port] [-4] [-6] -batch [username@]host command

           Except for the simple variant, command-line parameters are likely to change as git
           gains new features.

       stash.showIncludeUntracked
           If this is set to true, the git stash show command will show the untracked files of a
           stash entry. Defaults to false. See the description of the show command in git-
           stash(1).

       stash.showPatch
           If this is set to true, the git stash show command without an option will show the
           stash entry in patch form. Defaults to false. See the description of the show command
           in git-stash(1).

       stash.showStat
           If this is set to true, the git stash show command without an option will show a
           diffstat of the stash entry. Defaults to true. See the description of the show command
           in git-stash(1).

       status.relativePaths
           By default, git-status(1) shows paths relative to the current directory. Setting this
           variable to false shows paths relative to the repository root (this was the default
           for Git prior to v1.5.4).

       status.short
           Set to true to enable --short by default in git-status(1). The option --no-short takes
           precedence over this variable.

       status.branch
           Set to true to enable --branch by default in git-status(1). The option --no-branch
           takes precedence over this variable.

       status.aheadBehind
           Set to true to enable --ahead-behind and false to enable --no-ahead-behind by default
           in git-status(1) for non-porcelain status formats. Defaults to true.

       status.displayCommentPrefix
           If set to true, git-status(1) will insert a comment prefix before each output line
           (starting with core.commentChar, i.e.  # by default). This was the behavior of git-
           status(1) in Git 1.8.4 and previous. Defaults to false.

       status.renameLimit
           The number of files to consider when performing rename detection in git-status(1) and
           git-commit(1). Defaults to the value of diff.renameLimit.

       status.renames
           Whether and how Git detects renames in git-status(1) and git-commit(1) . If set to
           "false", rename detection is disabled. If set to "true", basic rename detection is
           enabled. If set to "copies" or "copy", Git will detect copies, as well. Defaults to
           the value of diff.renames.

       status.showStash
           If set to true, git-status(1) will display the number of entries currently stashed
           away. Defaults to false.

       status.showUntrackedFiles
           By default, git-status(1) and git-commit(1) show files which are not currently tracked
           by Git. Directories which contain only untracked files, are shown with the directory
           name only. Showing untracked files means that Git needs to lstat() all the files in
           the whole repository, which might be slow on some systems. So, this variable controls
           how the commands display the untracked files. Possible values are:

           •   no - Show no untracked files.

           •   normal - Show untracked files and directories.

           •   all - Show also individual files in untracked directories.

           If this variable is not specified, it defaults to normal. All usual spellings for
           Boolean value true are taken as normal and false as no. This variable can be
           overridden with the -u|--untracked-files option of git-status(1) and git-commit(1).

       status.submoduleSummary
           Defaults to false. If this is set to a non-zero number or true (identical to -1 or an
           unlimited number), the submodule summary will be enabled and a summary of commits for
           modified submodules will be shown (see --summary-limit option of git-submodule(1)).
           Please note that the summary output command will be suppressed for all submodules when
           diff.ignoreSubmodules is set to all or only for those submodules where
           submodule.<name>.ignore=all. The only exception to that rule is that status and commit
           will show staged submodule changes. To also view the summary for ignored submodules
           you can either use the --ignore-submodules=dirty command-line option or the git
           submodule summary command, which shows a similar output but does not honor these
           settings.

       submodule.<name>.url
           The URL for a submodule. This variable is copied from the .gitmodules file to the git
           config via git submodule init. The user can change the configured URL before obtaining
           the submodule via git submodule update. If neither submodule.<name>.active nor
           submodule.active are set, the presence of this variable is used as a fallback to
           indicate whether the submodule is of interest to git commands. See git-submodule(1)
           and gitmodules(5) for details.

       submodule.<name>.update
           The method by which a submodule is updated by git submodule update, which is the only
           affected command, others such as git checkout --recurse-submodules are unaffected. It
           exists for historical reasons, when git submodule was the only command to interact
           with submodules; settings like submodule.active and pull.rebase are more specific. It
           is populated by git submodule init from the gitmodules(5) file. See description of
           update command in git-submodule(1).

       submodule.<name>.branch
           The remote branch name for a submodule, used by git submodule update --remote. Set
           this option to override the value found in the .gitmodules file. See git-submodule(1)
           and gitmodules(5) for details.

       submodule.<name>.fetchRecurseSubmodules
           This option can be used to control recursive fetching of this submodule. It can be
           overridden by using the --[no-]recurse-submodules command-line option to "git fetch"
           and "git pull". This setting will override that from in the gitmodules(5) file.

       submodule.<name>.ignore
           Defines under what circumstances "git status" and the diff family show a submodule as
           modified. When set to "all", it will never be considered modified (but it will
           nonetheless show up in the output of status and commit when it has been staged),
           "dirty" will ignore all changes to the submodule’s work tree and takes only
           differences between the HEAD of the submodule and the commit recorded in the
           superproject into account. "untracked" will additionally let submodules with modified
           tracked files in their work tree show up. Using "none" (the default when this option
           is not set) also shows submodules that have untracked files in their work tree as
           changed. This setting overrides any setting made in .gitmodules for this submodule,
           both settings can be overridden on the command line by using the "--ignore-submodules"
           option. The git submodule commands are not affected by this setting.

       submodule.<name>.active
           Boolean value indicating if the submodule is of interest to git commands. This config
           option takes precedence over the submodule.active config option. See gitsubmodules(7)
           for details.

       submodule.active
           A repeated field which contains a pathspec used to match against a submodule’s path to
           determine if the submodule is of interest to git commands. See gitsubmodules(7) for
           details.

       submodule.recurse
           A boolean indicating if commands should enable the --recurse-submodules option by
           default. Defaults to false.

           When set to true, it can be deactivated via the --no-recurse-submodules option. Note
           that some Git commands lacking this option may call some of the above commands
           affected by submodule.recurse; for instance git remote update will call git fetch but
           does not have a --no-recurse-submodules option. For these commands a workaround is to
           temporarily change the configuration value by using git -c submodule.recurse=0.

           The following list shows the commands that accept --recurse-submodules and whether
           they are supported by this setting.

           •   checkout, fetch, grep, pull, push, read-tree, reset, restore and switch are always
               supported.

           •   clone and ls-files are not supported.

           •   branch is supported only if submodule.propagateBranches is enabled

       submodule.propagateBranches
           [EXPERIMENTAL] A boolean that enables branching support when using
           --recurse-submodules or submodule.recurse=true. Enabling this will allow certain
           commands to accept --recurse-submodules and certain commands that already accept
           --recurse-submodules will now consider branches. Defaults to false.

       submodule.fetchJobs
           Specifies how many submodules are fetched/cloned at the same time. A positive integer
           allows up to that number of submodules fetched in parallel. A value of 0 will give
           some reasonable default. If unset, it defaults to 1.

       submodule.alternateLocation
           Specifies how the submodules obtain alternates when submodules are cloned. Possible
           values are no, superproject. By default no is assumed, which doesn’t add references.
           When the value is set to superproject the submodule to be cloned computes its
           alternates location relative to the superprojects alternate.

       submodule.alternateErrorStrategy
           Specifies how to treat errors with the alternates for a submodule as computed via
           submodule.alternateLocation. Possible values are ignore, info, die. Default is die.
           Note that if set to ignore or info, and if there is an error with the computed
           alternate, the clone proceeds as if no alternate was specified.

       tag.forceSignAnnotated
           A boolean to specify whether annotated tags created should be GPG signed. If
           --annotate is specified on the command line, it takes precedence over this option.

       tag.sort
           This variable controls the sort ordering of tags when displayed by git-tag(1). Without
           the "--sort=<value>" option provided, the value of this variable will be used as the
           default.

       tag.gpgSign
           A boolean to specify whether all tags should be GPG signed. Use of this option when
           running in an automated script can result in a large number of tags being signed. It
           is therefore convenient to use an agent to avoid typing your gpg passphrase several
           times. Note that this option doesn’t affect tag signing behavior enabled by "-u
           <keyid>" or "--local-user=<keyid>" options.

       tar.umask
           This variable can be used to restrict the permission bits of tar archive entries. The
           default is 0002, which turns off the world write bit. The special value "user"
           indicates that the archiving user’s umask will be used instead. See umask(2) and git-
           archive(1).

       Trace2 config settings are only read from the system and global config files; repository
       local and worktree config files and -c command line arguments are not respected.

       trace2.normalTarget
           This variable controls the normal target destination. It may be overridden by the
           GIT_TRACE2 environment variable. The following table shows possible values.

       trace2.perfTarget
           This variable controls the performance target destination. It may be overridden by the
           GIT_TRACE2_PERF environment variable. The following table shows possible values.

       trace2.eventTarget
           This variable controls the event target destination. It may be overridden by the
           GIT_TRACE2_EVENT environment variable. The following table shows possible values.

           •   0 or false - Disables the target.

           •   1 or true - Writes to STDERR.

           •   [2-9] - Writes to the already opened file descriptor.

           •   <absolute-pathname> - Writes to the file in append mode. If the target already
               exists and is a directory, the traces will be written to files (one per process)
               underneath the given directory.

           •   af_unix:[<socket-type>:]<absolute-pathname> - Write to a Unix DomainSocket (on
               platforms that support them). Socket type can be either stream or dgram; if
               omitted Git will try both.

       trace2.normalBrief
           Boolean. When true time, filename, and line fields are omitted from normal output. May
           be overridden by the GIT_TRACE2_BRIEF environment variable. Defaults to false.

       trace2.perfBrief
           Boolean. When true time, filename, and line fields are omitted from PERF output. May
           be overridden by the GIT_TRACE2_PERF_BRIEF environment variable. Defaults to false.

       trace2.eventBrief
           Boolean. When true time, filename, and line fields are omitted from event output. May
           be overridden by the GIT_TRACE2_EVENT_BRIEF environment variable. Defaults to false.

       trace2.eventNesting
           Integer. Specifies desired depth of nested regions in the event output. Regions deeper
           than this value will be omitted. May be overridden by the GIT_TRACE2_EVENT_NESTING
           environment variable. Defaults to 2.

       trace2.configParams
           A comma-separated list of patterns of "important" config settings that should be
           recorded in the trace2 output. For example, core.*,remote.*.url would cause the trace2
           output to contain events listing each configured remote. May be overridden by the
           GIT_TRACE2_CONFIG_PARAMS environment variable. Unset by default.

       trace2.envVars
           A comma-separated list of "important" environment variables that should be recorded in
           the trace2 output. For example, GIT_HTTP_USER_AGENT,GIT_CONFIG would cause the trace2
           output to contain events listing the overrides for HTTP user agent and the location of
           the Git configuration file (assuming any are set). May be overridden by the
           GIT_TRACE2_ENV_VARS environment variable. Unset by default.

       trace2.destinationDebug
           Boolean. When true Git will print error messages when a trace target destination
           cannot be opened for writing. By default, these errors are suppressed and tracing is
           silently disabled. May be overridden by the GIT_TRACE2_DST_DEBUG environment variable.

       trace2.maxFiles
           Integer. When writing trace files to a target directory, do not write additional
           traces if doing so would exceed this many files. Instead, write a sentinel file that
           will block further tracing to this directory. Defaults to 0, which disables this
           check.

       transfer.credentialsInUrl
           A configured URL can contain plaintext credentials in the form
           <protocol>://<user>:<password>@<domain>/<path>. You may want to warn or forbid the use
           of such configuration (in favor of using git-credential(1)). This will be used on git-
           clone(1), git-fetch(1), git-push(1), and any other direct use of the configured URL.

           Note that this is currently limited to detecting credentials in remote.<name>.url
           configuration; it won’t detect credentials in remote.<name>.pushurl configuration.

           You might want to enable this to prevent inadvertent credentials exposure, e.g.
           because:

           •   The OS or system where you’re running git may not provide a way or otherwise allow
               you to configure the permissions of the configuration file where the username
               and/or password are stored.

           •   Even if it does, having such data stored "at rest" might expose you in other ways,
               e.g. a backup process might copy the data to another system.

           •   The git programs will pass the full URL to one another as arguments on the
               command-line, meaning the credentials will be exposed to other unprivileged users
               on systems that allow them to see the full process list of other users. On linux
               the "hidepid" setting documented in procfs(5) allows for configuring this
               behavior.

               If such concerns don’t apply to you then you probably don’t need to be concerned
               about credentials exposure due to storing sensitive data in git’s configuration
               files. If you do want to use this, set transfer.credentialsInUrl to one of these
               values:

           •   allow (default): Git will proceed with its activity without warning.

           •   warn: Git will write a warning message to stderr when parsing a URL with a
               plaintext credential.

           •   die: Git will write a failure message to stderr when parsing a URL with a
               plaintext credential.

       transfer.fsckObjects
           When fetch.fsckObjects or receive.fsckObjects are not set, the value of this variable
           is used instead. Defaults to false.

           When set, the fetch or receive will abort in the case of a malformed object or a link
           to a nonexistent object. In addition, various other issues are checked for, including
           legacy issues (see fsck.<msg-id>), and potential security issues like the existence of
           a .GIT directory or a malicious .gitmodules file (see the release notes for v2.2.1 and
           v2.17.1 for details). Other sanity and security checks may be added in future
           releases.

           On the receiving side, failing fsckObjects will make those objects unreachable, see
           "QUARANTINE ENVIRONMENT" in git-receive-pack(1). On the fetch side, malformed objects
           will instead be left unreferenced in the repository.

           Due to the non-quarantine nature of the fetch.fsckObjects implementation it cannot be
           relied upon to leave the object store clean like receive.fsckObjects can.

           As objects are unpacked they’re written to the object store, so there can be cases
           where malicious objects get introduced even though the "fetch" failed, only to have a
           subsequent "fetch" succeed because only new incoming objects are checked, not those
           that have already been written to the object store. That difference in behavior should
           not be relied upon. In the future, such objects may be quarantined for "fetch" as
           well.

           For now, the paranoid need to find some way to emulate the quarantine environment if
           they’d like the same protection as "push". E.g. in the case of an internal mirror do
           the mirroring in two steps, one to fetch the untrusted objects, and then do a second
           "push" (which will use the quarantine) to another internal repo, and have internal
           clients consume this pushed-to repository, or embargo internal fetches and only allow
           them once a full "fsck" has run (and no new fetches have happened in the meantime).

       transfer.hideRefs
           String(s) receive-pack and upload-pack use to decide which refs to omit from their
           initial advertisements. Use more than one definition to specify multiple prefix
           strings. A ref that is under the hierarchies listed in the value of this variable is
           excluded, and is hidden when responding to git push or git fetch. See receive.hideRefs
           and uploadpack.hideRefs for program-specific versions of this config.

           You may also include a !  in front of the ref name to negate the entry, explicitly
           exposing it, even if an earlier entry marked it as hidden. If you have multiple
           hideRefs values, later entries override earlier ones (and entries in more-specific
           config files override less-specific ones).

           If a namespace is in use, the namespace prefix is stripped from each reference before
           it is matched against transfer.hiderefs patterns. In order to match refs before
           stripping, add a ^ in front of the ref name. If you combine !  and ^, !  must be
           specified first.

           For example, if refs/heads/master is specified in transfer.hideRefs and the current
           namespace is foo, then refs/namespaces/foo/refs/heads/master is omitted from the
           advertisements. If uploadpack.allowRefInWant is set, upload-pack will treat want-ref
           refs/heads/master in a protocol v2 fetch command as if
           refs/namespaces/foo/refs/heads/master did not exist.  receive-pack, on the other hand,
           will still advertise the object id the ref is pointing to without mentioning its name
           (a so-called ".have" line).

           Even if you hide refs, a client may still be able to steal the target objects via the
           techniques described in the "SECURITY" section of the gitnamespaces(7) man page; it’s
           best to keep private data in a separate repository.

       transfer.unpackLimit
           When fetch.unpackLimit or receive.unpackLimit are not set, the value of this variable
           is used instead. The default value is 100.

       transfer.advertiseSID
           Boolean. When true, client and server processes will advertise their unique session
           IDs to their remote counterpart. Defaults to false.

       transfer.bundleURI
           When true, local git clone commands will request bundle information from the remote
           server (if advertised) and download bundles before continuing the clone through the
           Git protocol. Defaults to false.

       transfer.advertiseObjectInfo
           When true, the object-info capability is advertised by servers. Defaults to false.

       uploadarchive.allowUnreachable
           If true, allow clients to use git archive --remote to request any tree, whether
           reachable from the ref tips or not. See the discussion in the "SECURITY" section of
           git-upload-archive(1) for more details. Defaults to false.

       uploadpack.hideRefs
           This variable is the same as transfer.hideRefs, but applies only to upload-pack (and
           so affects only fetches, not pushes). An attempt to fetch a hidden ref by git fetch
           will fail. See also uploadpack.allowTipSHA1InWant.

       uploadpack.allowTipSHA1InWant
           When uploadpack.hideRefs is in effect, allow upload-pack to accept a fetch request
           that asks for an object at the tip of a hidden ref (by default, such a request is
           rejected). See also uploadpack.hideRefs. Even if this is false, a client may be able
           to steal objects via the techniques described in the "SECURITY" section of the
           gitnamespaces(7) man page; it’s best to keep private data in a separate repository.

       uploadpack.allowReachableSHA1InWant
           Allow upload-pack to accept a fetch request that asks for an object that is reachable
           from any ref tip. However, note that calculating object reachability is
           computationally expensive. Defaults to false. Even if this is false, a client may be
           able to steal objects via the techniques described in the "SECURITY" section of the
           gitnamespaces(7) man page; it’s best to keep private data in a separate repository.

       uploadpack.allowAnySHA1InWant
           Allow upload-pack to accept a fetch request that asks for any object at all. Defaults
           to false.

       uploadpack.keepAlive
           When upload-pack has started pack-objects, there may be a quiet period while
           pack-objects prepares the pack. Normally it would output progress information, but if
           --quiet was used for the fetch, pack-objects will output nothing at all until the pack
           data begins. Some clients and networks may consider the server to be hung and give up.
           Setting this option instructs upload-pack to send an empty keepalive packet every
           uploadpack.keepAlive seconds. Setting this option to 0 disables keepalive packets
           entirely. The default is 5 seconds.

       uploadpack.packObjectsHook
           If this option is set, when upload-pack would run git pack-objects to create a
           packfile for a client, it will run this shell command instead. The pack-objects
           command and arguments it would have run (including the git pack-objects at the
           beginning) are appended to the shell command. The stdin and stdout of the hook are
           treated as if pack-objects itself was run. I.e., upload-pack will feed input intended
           for pack-objects to the hook, and expects a completed packfile on stdout.

           Note that this configuration variable is only respected when it is specified in
           protected configuration (see the section called “SCOPES”). This is a safety measure
           against fetching from untrusted repositories.

       uploadpack.allowFilter
           If this option is set, upload-pack will support partial clone and partial fetch object
           filtering.

       uploadpackfilter.allow
           Provides a default value for unspecified object filters (see: the below configuration
           variable). If set to true, this will also enable all filters which get added in the
           future. Defaults to true.

       uploadpackfilter.<filter>.allow
           Explicitly allow or ban the object filter corresponding to <filter>, where <filter>
           may be one of: blob:none, blob:limit, object:type, tree, sparse:oid, or combine. If
           using combined filters, both combine and all of the nested filter kinds must be
           allowed. Defaults to uploadpackfilter.allow.

       uploadpackfilter.tree.maxDepth
           Only allow --filter=tree:<n> when <n> is no more than the value of
           uploadpackfilter.tree.maxDepth. If set, this also implies
           uploadpackfilter.tree.allow=true, unless this configuration variable had already been
           set. Has no effect if unset.

       uploadpack.allowRefInWant
           If this option is set, upload-pack will support the ref-in-want feature of the
           protocol version 2 fetch command. This feature is intended for the benefit of
           load-balanced servers which may not have the same view of what OIDs their refs point
           to due to replication delay.

       url.<base>.insteadOf
           Any URL that starts with this value will be rewritten to start, instead, with <base>.
           In cases where some site serves a large number of repositories, and serves them with
           multiple access methods, and some users need to use different access methods, this
           feature allows people to specify any of the equivalent URLs and have Git automatically
           rewrite the URL to the best alternative for the particular user, even for a
           never-before-seen repository on the site. When more than one insteadOf strings match a
           given URL, the longest match is used.

           Note that any protocol restrictions will be applied to the rewritten URL. If the
           rewrite changes the URL to use a custom protocol or remote helper, you may need to
           adjust the protocol.*.allow config to permit the request. In particular, protocols you
           expect to use for submodules must be set to always rather than the default of user.
           See the description of protocol.allow above.

       url.<base>.pushInsteadOf
           Any URL that starts with this value will not be pushed to; instead, it will be
           rewritten to start with <base>, and the resulting URL will be pushed to. In cases
           where some site serves a large number of repositories, and serves them with multiple
           access methods, some of which do not allow push, this feature allows people to specify
           a pull-only URL and have Git automatically use an appropriate URL to push, even for a
           never-before-seen repository on the site. When more than one pushInsteadOf strings
           match a given URL, the longest match is used. If a remote has an explicit pushurl, Git
           will ignore this setting for that remote.

       user.name, user.email, author.name, author.email, committer.name, committer.email
           The user.name and user.email variables determine what ends up in the author and
           committer fields of commit objects. If you need the author or committer to be
           different, the author.name, author.email, committer.name, or committer.email variables
           can be set. All of these can be overridden by the GIT_AUTHOR_NAME, GIT_AUTHOR_EMAIL,
           GIT_COMMITTER_NAME, GIT_COMMITTER_EMAIL, and EMAIL environment variables.

           Note that the name forms of these variables conventionally refer to some form of a
           personal name. See git-commit(1) and the environment variables section of git(1) for
           more information on these settings and the credential.username option if you’re
           looking for authentication credentials instead.

       user.useConfigOnly
           Instruct Git to avoid trying to guess defaults for user.email and user.name, and
           instead retrieve the values only from the configuration. For example, if you have
           multiple email addresses and would like to use a different one for each repository,
           then with this configuration option set to true in the global config along with a
           name, Git will prompt you to set up an email before making new commits in a newly
           cloned repository. Defaults to false.

       user.signingKey
           If git-tag(1) or git-commit(1) is not selecting the key you want it to automatically
           when creating a signed tag or commit, you can override the default selection with this
           variable. This option is passed unchanged to gpg’s --local-user parameter, so you may
           specify a key using any method that gpg supports. If gpg.format is set to ssh this can
           contain the path to either your private ssh key or the public key when ssh-agent is
           used. Alternatively it can contain a public key prefixed with key:: directly (e.g.:
           "key::ssh-rsa XXXXXX identifier"). The private key needs to be available via
           ssh-agent. If not set Git will call gpg.ssh.defaultKeyCommand (e.g.: "ssh-add -L") and
           try to use the first key available. For backward compatibility, a raw key which begins
           with "ssh-", such as "ssh-rsa XXXXXX identifier", is treated as "key::ssh-rsa XXXXXX
           identifier", but this form is deprecated; use the key:: form instead.

       versionsort.prereleaseSuffix (deprecated)
           Deprecated alias for versionsort.suffix. Ignored if versionsort.suffix is set.

       versionsort.suffix
           Even when version sort is used in git-tag(1), tagnames with the same base version but
           different suffixes are still sorted lexicographically, resulting e.g. in prerelease
           tags appearing after the main release (e.g. "1.0-rc1" after "1.0"). This variable can
           be specified to determine the sorting order of tags with different suffixes.

           By specifying a single suffix in this variable, any tagname containing that suffix
           will appear before the corresponding main release. E.g. if the variable is set to
           "-rc", then all "1.0-rcX" tags will appear before "1.0". If specified multiple times,
           once per suffix, then the order of suffixes in the configuration will determine the
           sorting order of tagnames with those suffixes. E.g. if "-pre" appears before "-rc" in
           the configuration, then all "1.0-preX" tags will be listed before any "1.0-rcX" tags.
           The placement of the main release tag relative to tags with various suffixes can be
           determined by specifying the empty suffix among those other suffixes. E.g. if the
           suffixes "-rc", "", "-ck", and "-bfs" appear in the configuration in this order, then
           all "v4.8-rcX" tags are listed first, followed by "v4.8", then "v4.8-ckX" and finally
           "v4.8-bfsX".

           If more than one suffix matches the same tagname, then that tagname will be sorted
           according to the suffix which starts at the earliest position in the tagname. If more
           than one different matching suffix starts at that earliest position, then that tagname
           will be sorted according to the longest of those suffixes. The sorting order between
           different suffixes is undefined if they are in multiple config files.

       web.browser
           Specify a web browser that may be used by some commands. Currently only git-
           instaweb(1) and git-help(1) may use it.

       worktree.guessRemote
           If no branch is specified and neither -b nor -B nor --detach is used, then git
           worktree add defaults to creating a new branch from HEAD. If worktree.guessRemote is
           set to true, worktree add tries to find a remote-tracking branch whose name uniquely
           matches the new branch name. If such a branch exists, it is checked out and set as
           "upstream" for the new branch. If no such match can be found, it falls back to
           creating a new branch from the current HEAD.

BUGS

       When using the deprecated [section.subsection] syntax, changing a value will result in
       adding a multi-line key instead of a change, if the subsection is given with at least one
       uppercase character. For example when the config looks like

             [section.subsection]
               key = value1

       and running git config section.Subsection.key value2 will result in

             [section.subsection]
               key = value1
               key = value2
