       git-grep - Print lines matching a pattern


       git grep [-a | --text] [-I] [--textconv] [-i | --ignore-case] [-w | --word-regexp]
                  [-v | --invert-match] [-h|-H] [--full-name]
                  [-E | --extended-regexp] [-G | --basic-regexp]
                  [-P | --perl-regexp]
                  [-F | --fixed-strings] [-n | --line-number]
                  [-l | --files-with-matches] [-L | --files-without-match]
                  [(-O | --open-files-in-pager) [<pager>]]
                  [-z | --null]
                  [-c | --count] [--all-match] [-q | --quiet]
                  [--max-depth <depth>]
                  [--color[=<when>] | --no-color]
                  [--break] [--heading] [-p | --show-function]
                  [-A <post-context>] [-B <pre-context>] [-C <context>]
                  [-W | --function-context]
                  [--threads <num>]
                  [-f <file>] [-e] <pattern>
                  [--and|--or|--not|(|)|-e <pattern>...]
                  [--recurse-submodules] [--parent-basename <basename>]
                  [ [--[no-]exclude-standard] [--cached | --no-index | --untracked] | <tree>...]
                  [--] [<pathspec>...]


       Look for specified patterns in the tracked files in the work tree, blobs registered in the
       index file, or blobs in given tree objects. Patterns are lists of one or more search
       expressions separated by newline characters. An empty string as search expression matches
       all lines.


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

           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 return to the default matching

           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.

           Number of grep worker threads to use. If unset (or set to 0), 8 threads are used by
           default (for now).

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

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


           Instead of searching tracked files in the working tree, search blobs registered in the
           index file.

           Search files in the current directory that is not managed by Git.

           In addition to searching in the tracked files in the working tree, search also in
           untracked files.

           Also search in ignored files by not honoring the .gitignore mechanism. Only useful
           with --untracked.

           Do not pay attention to ignored files specified via the .gitignore mechanism. Only
           useful when searching files in the current directory with --no-index.

           Recursively search in each submodule that has been initialized and checked out in the
           repository. When used in combination with the <tree> option the prefix of all
           submodule output will be the name of the parent project’s <tree> object.

       -a, --text
           Process binary files as if they were text.

           Honor textconv filter settings.

           Do not honor textconv filter settings. This is the default.

       -i, --ignore-case
           Ignore case differences between the patterns and the files.

           Don’t match the pattern in binary files.

       --max-depth <depth>
           For each <pathspec> given on command line, descend at most <depth> levels of
           directories. A negative value means no limit. This option is ignored if <pathspec>
           contains active wildcards. In other words if "a*" matches a directory named "a*", "*"
           is matched literally so --max-depth is still effective.

       -w, --word-regexp
           Match the pattern only at word boundary (either begin at the beginning of a line, or
           preceded by a non-word character; end at the end of a line or followed by a non-word

       -v, --invert-match
           Select non-matching lines.

       -h, -H
           By default, the command shows the filename for each match.  -h option is used to
           suppress this output.  -H is there for completeness and does not do anything except it
           overrides -h given earlier on the command line.

           When run from a subdirectory, the command usually outputs paths relative to the
           current directory. This option forces paths to be output relative to the project top

       -E, --extended-regexp, -G, --basic-regexp
           Use POSIX extended/basic regexp for patterns. Default is to use basic regexp.

       -P, --perl-regexp
           Use Perl-compatible regular expressions for patterns.

           Support for these types of regular expressions is an optional compile-time dependency.
           If Git wasn’t compiled with support for them providing this option will cause it to

       -F, --fixed-strings
           Use fixed strings for patterns (don’t interpret pattern as a regex).

       -n, --line-number
           Prefix the line number to matching lines.

       -l, --files-with-matches, --name-only, -L, --files-without-match
           Instead of showing every matched line, show only the names of files that contain (or
           do not contain) matches. For better compatibility with git diff, --name-only is a
           synonym for --files-with-matches.

       -O[<pager>], --open-files-in-pager[=<pager>]
           Open the matching files in the pager (not the output of grep). If the pager happens to
           be "less" or "vi", and the user specified only one pattern, the first file is
           positioned at the first match automatically. The pager argument is optional; if
           specified, it must be stuck to the option without a space. If pager is unspecified,
           the default pager will be used (see core.pager in git-config(1)).

       -z, --null
           Output \0 instead of the character that normally follows a file name.

       -c, --count
           Instead of showing every matched line, show the number of lines that match.

           Show colored matches. The value must be always (the default), never, or auto.

           Turn off match highlighting, even when the configuration file gives the default to
           color output. Same as --color=never.

           Print an empty line between matches from different files.

           Show the filename above the matches in that file instead of at the start of each shown

       -p, --show-function
           Show the preceding line that contains the function name of the match, unless the
           matching line is a function name itself. The name is determined in the same way as git
           diff works out patch hunk headers (see Defining a custom hunk-header in

       -<num>, -C <num>, --context <num>
           Show <num> leading and trailing lines, and place a line containing -- between
           contiguous groups of matches.

       -A <num>, --after-context <num>
           Show <num> trailing lines, and place a line containing -- between contiguous groups of

       -B <num>, --before-context <num>
           Show <num> leading lines, and place a line containing -- between contiguous groups of

       -W, --function-context
           Show the surrounding text from the previous line containing a function name up to the
           one before the next function name, effectively showing the whole function in which the
           match was found.

       --threads <num>
           Number of grep worker threads to use. See grep.threads in CONFIGURATION for more

       -f <file>
           Read patterns from <file>, one per line.

           The next parameter is the pattern. This option has to be used for patterns starting
           with - and should be used in scripts passing user input to grep. Multiple patterns are
           combined by or.

       --and, --or, --not, ( ... )
           Specify how multiple patterns are combined using Boolean expressions.  --or is the
           default operator.  --and has higher precedence than --or.  -e has to be used for all

           When giving multiple pattern expressions combined with --or, this flag is specified to
           limit the match to files that have lines to match all of them.

       -q, --quiet
           Do not output matched lines; instead, exit with status 0 when there is a match and
           with non-zero status when there isn’t.

           Instead of searching tracked files in the working tree, search blobs in the given

           Signals the end of options; the rest of the parameters are <pathspec> limiters.

           If given, limit the search to paths matching at least one pattern. Both leading paths
           match and glob(7) patterns are supported.

           For more details about the <pathspec> syntax, see the pathspec entry in


       git grep 'time_t' -- '*.[ch]'
           Looks for time_t in all tracked .c and .h files in the working directory and its

       git grep -e '#define' --and \( -e MAX_PATH -e PATH_MAX \)
           Looks for a line that has #define and either MAX_PATH or PATH_MAX.

       git grep --all-match -e NODE -e Unexpected
           Looks for a line that has NODE or Unexpected in files that have lines that match both.

       git grep solution -- :^Documentation
           Looks for solution, excluding files in Documentation.
