NAME

       git-send-email - Send a collection of patches as emails

SYNOPSIS

       git send-email [options] <file|directory|rev-list options>...
       git send-email --dump-aliases

DESCRIPTION

       Takes the patches given on the command line and emails them out. Patches can be specified as files,
       directories (which will send all files in the directory), or directly as a revision list. In the last
       case, any format accepted by git-format-patch(1) can be passed to git send-email.

       The header of the email is configurable via command-line options. If not specified on the command line,
       the user will be prompted with a ReadLine enabled interface to provide the necessary information.

       There are two formats accepted for patch files:

        1. mbox format files

           This is what git-format-patch(1) generates. Most headers and MIME formatting are ignored.

        2. The original format used by Greg Kroah-Hartman’s send_lots_of_email.pl script

           This format expects the first line of the file to contain the "Cc:" value and the "Subject:" of the
           message as the second line.

OPTIONS

   Composing
       --annotate
           Review and edit each patch you’re about to send. Default is the value of sendemail.annotate. See the
           CONFIGURATION section for sendemail.multiEdit.

       --bcc=<address>,...
           Specify a "Bcc:" value for each email. Default is the value of sendemail.bcc.

           This option may be specified multiple times.

       --cc=<address>,...
           Specify a starting "Cc:" value for each email. Default is the value of sendemail.cc.

           This option may be specified multiple times.

       --compose
           Invoke a text editor (see GIT_EDITOR in git-var(1)) to edit an introductory message for the patch
           series.

           When --compose is used, git send-email will use the From, Subject, and In-Reply-To headers specified
           in the message. If the body of the message (what you type after the headers and a blank line) only
           contains blank (or Git: prefixed) lines, the summary won’t be sent, but From, Subject, and
           In-Reply-To headers will be used unless they are removed.

           Missing From or In-Reply-To headers will be prompted for.

           See the CONFIGURATION section for sendemail.multiEdit.

       --from=<address>
           Specify the sender of the emails. If not specified on the command line, the value of the
           sendemail.from configuration option is used. If neither the command-line option nor sendemail.from
           are set, then the user will be prompted for the value. The default for the prompt will be the value
           of GIT_AUTHOR_IDENT, or GIT_COMMITTER_IDENT if that is not set, as returned by "git var -l".

       --reply-to=<address>
           Specify the address where replies from recipients should go to. Use this if replies to messages
           should go to another address than what is specified with the --from parameter.

       --in-reply-to=<identifier>
           Make the first mail (or all the mails with --no-thread) appear as a reply to the given Message-Id,
           which avoids breaking threads to provide a new patch series. The second and subsequent emails will be
           sent as replies according to the --[no-]chain-reply-to setting.

           So for example when --thread and --no-chain-reply-to are specified, the second and subsequent patches
           will be replies to the first one like in the illustration below where [PATCH v2 0/3] is in reply to
           [PATCH 0/2]:

               [PATCH 0/2] Here is what I did...
                 [PATCH 1/2] Clean up and tests
                 [PATCH 2/2] Implementation
                 [PATCH v2 0/3] Here is a reroll
                   [PATCH v2 1/3] Clean up
                   [PATCH v2 2/3] New tests
                   [PATCH v2 3/3] Implementation

           Only necessary if --compose is also set. If --compose is not set, this will be prompted for.

       --subject=<string>
           Specify the initial subject of the email thread. Only necessary if --compose is also set. If
           --compose is not set, this will be prompted for.

       --to=<address>,...
           Specify the primary recipient of the emails generated. Generally, this will be the upstream
           maintainer of the project involved. Default is the value of the sendemail.to configuration value; if
           that is unspecified, and --to-cmd is not specified, this will be prompted for.

           This option may be specified multiple times.

       --8bit-encoding=<encoding>
           When encountering a non-ASCII message or subject that does not declare its encoding, add
           headers/quoting to indicate it is encoded in <encoding>. Default is the value of the
           sendemail.assume8bitEncoding; if that is unspecified, this will be prompted for if any non-ASCII
           files are encountered.

           Note that no attempts whatsoever are made to validate the encoding.

       --compose-encoding=<encoding>
           Specify encoding of compose message. Default is the value of the sendemail.composeencoding; if that
           is unspecified, UTF-8 is assumed.

       --transfer-encoding=(7bit|8bit|quoted-printable|base64)
           Specify the transfer encoding to be used to send the message over SMTP. 7bit will fail upon
           encountering a non-ASCII message. quoted-printable can be useful when the repository contains files
           that contain carriage returns, but makes the raw patch email file (as saved from a MUA) much harder
           to inspect manually. base64 is even more fool proof, but also even more opaque. Default is the value
           of the sendemail.transferEncoding configuration value; if that is unspecified, git will use 8bit and
           not add a Content-Transfer-Encoding header.

       --xmailer, --no-xmailer
           Add (or prevent adding) the "X-Mailer:" header. By default, the header is added, but it can be turned
           off by setting the sendemail.xmailer configuration variable to false.

   Sending
       --envelope-sender=<address>
           Specify the envelope sender used to send the emails. This is useful if your default address is not
           the address that is subscribed to a list. In order to use the From address, set the value to "auto".
           If you use the sendmail binary, you must have suitable privileges for the -f parameter. Default is
           the value of the sendemail.envelopeSender configuration variable; if that is unspecified, choosing
           the envelope sender is left to your MTA.

       --smtp-encryption=<encryption>
           Specify the encryption to use, either ssl or tls. Any other value reverts to plain SMTP. Default is
           the value of sendemail.smtpEncryption.

       --smtp-domain=<FQDN>
           Specifies the Fully Qualified Domain Name (FQDN) used in the HELO/EHLO command to the SMTP server.
           Some servers require the FQDN to match your IP address. If not set, git send-email attempts to
           determine your FQDN automatically. Default is the value of sendemail.smtpDomain.

       --smtp-auth=<mechanisms>
           Whitespace-separated list of allowed SMTP-AUTH mechanisms. This setting forces using only the listed
           mechanisms. Example:

               $ git send-email --smtp-auth="PLAIN LOGIN GSSAPI" ...

           If at least one of the specified mechanisms matches the ones advertised by the SMTP server and if it
           is supported by the utilized SASL library, the mechanism is used for authentication. If neither
           sendemail.smtpAuth nor --smtp-auth is specified, all mechanisms supported by the SASL library can be
           used.

       --smtp-pass[=<password>]
           Password for SMTP-AUTH. The argument is optional: If no argument is specified, then the empty string
           is used as the password. Default is the value of sendemail.smtpPass, however --smtp-pass always
           overrides this value.

           Furthermore, passwords need not be specified in configuration files or on the command line. If a
           username has been specified (with --smtp-user or a sendemail.smtpUser), but no password has been
           specified (with --smtp-pass or sendemail.smtpPass), then a password is obtained using git-credential.

       --smtp-server=<host>
           If set, specifies the outgoing SMTP server to use (e.g.  smtp.example.com or a raw IP address).
           Alternatively it can specify a full pathname of a sendmail-like program instead; the program must
           support the -i option. Default value can be specified by the sendemail.smtpServer configuration
           option; the built-in default is to search for sendmail in /usr/sbin, /usr/lib and $PATH if such
           program is available, falling back to localhost otherwise.

       --smtp-server-port=<port>
           Specifies a port different from the default port (SMTP servers typically listen to smtp port 25, but
           may also listen to submission port 587, or the common SSL smtp port 465); symbolic port names (e.g.
           "submission" instead of 587) are also accepted. The port can also be set with the
           sendemail.smtpServerPort configuration variable.

       --smtp-server-option=<option>
           If set, specifies the outgoing SMTP server option to use. Default value can be specified by the
           sendemail.smtpServerOption configuration option.

           The --smtp-server-option option must be repeated for each option you want to pass to the server.
           Likewise, different lines in the configuration files must be used for each option.

       --smtp-ssl
           Legacy alias for --smtp-encryption ssl.

       --smtp-ssl-cert-path
           Path to a store of trusted CA certificates for SMTP SSL/TLS certificate validation (either a
           directory that has been processed by c_rehash, or a single file containing one or more PEM format
           certificates concatenated together: see verify(1) -CAfile and -CApath for more information on these).
           Set it to an empty string to disable certificate verification. Defaults to the value of the
           sendemail.smtpsslcertpath configuration variable, if set, or the backing SSL library’s compiled-in
           default otherwise (which should be the best choice on most platforms).

       --smtp-user=<user>
           Username for SMTP-AUTH. Default is the value of sendemail.smtpUser; if a username is not specified
           (with --smtp-user or sendemail.smtpUser), then authentication is not attempted.

       --smtp-debug=0|1
           Enable (1) or disable (0) debug output. If enabled, SMTP commands and replies will be printed. Useful
           to debug TLS connection and authentication problems.

       --batch-size=<num>
           Some email servers (e.g. smtp.163.com) limit the number emails to be sent per session (connection)
           and this will lead to a faliure when sending many messages. With this option, send-email will
           disconnect after sending $<num> messages and wait for a few seconds (see --relogin-delay) and
           reconnect, to work around such a limit. You may want to use some form of credential helper to avoid
           having to retype your password every time this happens. Defaults to the sendemail.smtpBatchSize
           configuration variable.

       --relogin-delay=<int>
           Waiting $<int> seconds before reconnecting to SMTP server. Used together with --batch-size option.
           Defaults to the sendemail.smtpReloginDelay configuration variable.

   Automating
       --to-cmd=<command>
           Specify a command to execute once per patch file which should generate patch file specific "To:"
           entries. Output of this command must be single email address per line. Default is the value of
           sendemail.tocmd configuration value.

       --cc-cmd=<command>
           Specify a command to execute once per patch file which should generate patch file specific "Cc:"
           entries. Output of this command must be single email address per line. Default is the value of
           sendemail.ccCmd configuration value.

       --[no-]chain-reply-to
           If this is set, each email will be sent as a reply to the previous email sent. If disabled with
           "--no-chain-reply-to", all emails after the first will be sent as replies to the first email sent.
           When using this, it is recommended that the first file given be an overview of the entire patch
           series. Disabled by default, but the sendemail.chainReplyTo configuration variable can be used to
           enable it.

       --identity=<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.

       --[no-]signed-off-by-cc
           If this is set, add emails found in Signed-off-by: or Cc: lines to the cc list. Default is the value
           of sendemail.signedoffbycc configuration value; if that is unspecified, default to
           --signed-off-by-cc.

       --[no-]cc-cover
           If this is set, emails found in Cc: headers in the first patch of the series (typically the cover
           letter) are added to the cc list for each email set. Default is the value of sendemail.cccover
           configuration value; if that is unspecified, default to --no-cc-cover.

       --[no-]to-cover
           If this is set, emails found in To: headers in the first patch of the series (typically the cover
           letter) are added to the to list for each email set. Default is the value of sendemail.tocover
           configuration value; if that is unspecified, default to --no-to-cover.

       --suppress-cc=<category>
           Specify an additional category of recipients to suppress the auto-cc of:

           •   author will avoid including the patch author

           •   self will avoid including the sender

           •   cc will avoid including anyone mentioned in Cc lines in the patch header except for self (use
               self for that).

           •   bodycc will avoid including anyone mentioned in Cc lines in the patch body (commit message)
               except for self (use self for that).

           •   sob will avoid including anyone mentioned in Signed-off-by lines except for self (use self for
               that).

           •   cccmd will avoid running the --cc-cmd.

           •   body is equivalent to sob + bodyccall will suppress all auto cc values.

           Default is the value of sendemail.suppresscc configuration value; if that is unspecified, default to
           self if --suppress-from is specified, as well as body if --no-signed-off-cc is specified.

       --[no-]suppress-from
           If this is set, do not add the From: address to the cc: list. Default is the value of
           sendemail.suppressFrom configuration value; if that is unspecified, default to --no-suppress-from.

       --[no-]thread
           If this is set, the In-Reply-To and References headers will be added to each email sent. Whether each
           mail refers to the previous email (deep threading per git format-patch wording) or to the first email
           (shallow threading) is governed by "--[no-]chain-reply-to".

           If disabled with "--no-thread", those headers will not be added (unless specified with
           --in-reply-to). Default is the value of the sendemail.thread configuration value; if that is
           unspecified, default to --thread.

           It is up to the user to ensure that no In-Reply-To header already exists when git send-email is asked
           to add it (especially note that git format-patch can be configured to do the threading itself).
           Failure to do so may not produce the expected result in the recipient’s MUA.

   Administering
       --confirm=<mode>
           Confirm just before sending:

           •   always will always confirm before sending

           •   never will never confirm before sending

           •   cc will confirm before sending when send-email has automatically added addresses from the patch
               to the Cc list

           •   compose will confirm before sending the first message when using --compose.

           •   auto is equivalent to cc + compose

           Default is the value of sendemail.confirm configuration value; if that is unspecified, default to
           auto unless any of the suppress options have been specified, in which case default to compose.

       --dry-run
           Do everything except actually send the emails.

       --[no-]format-patch
           When an argument may be understood either as a reference or as a file name, choose to understand it
           as a format-patch argument (--format-patch) or as a file name (--no-format-patch). By default, when
           such a conflict occurs, git send-email will fail.

       --quiet
           Make git-send-email less verbose. One line per email should be all that is output.

       --[no-]validate
           Perform sanity checks on patches. Currently, validation means the following:

           •   Invoke the sendemail-validate hook if present (see githooks(5)).

           •   Warn of patches that contain lines longer than 998 characters; this is due to SMTP limits as
               described by http://www.ietf.org/rfc/rfc2821.txt.

           Default is the value of sendemail.validate; if this is not set, default to --validate.

       --force
           Send emails even if safety checks would prevent it.

   Information
       --dump-aliases
           Instead of the normal operation, dump the shorthand alias names from the configured alias file(s),
           one per line in alphabetical order. Note, this only includes the alias name and not its expanded
           email addresses. See sendemail.aliasesfile for more information about aliases.

CONFIGURATION

       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, or
           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.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 previous section for the meaning of these values.

EXAMPLE

   Use gmail as the smtp server
       To use git send-email to send your patches through the GMail SMTP server, edit ~/.gitconfig to specify
       your account settings:

           [sendemail]
                   smtpEncryption = tls
                   smtpServer = smtp.gmail.com
                   smtpUser = yourname@gmail.com
                   smtpServerPort = 587

       If you have multifactor authentication setup on your gmail account, you will need to generate an
       app-specific password for use with git send-email. Visit
       https://security.google.com/settings/security/apppasswords to setup an app-specific password. Once setup,
       you can store it with the credentials helper:

           $ git credential fill
           protocol=smtp
           host=smtp.gmail.com
           username=youname@gmail.com
           password=app-password

       Once your commits are ready to be sent to the mailing list, run the following commands:

           $ git format-patch --cover-letter -M origin/master -o outgoing/
           $ edit outgoing/0000-*
           $ git send-email outgoing/*

       Note: the following perl modules are required Net::SMTP::SSL, MIME::Base64 and Authen::SASL
