   9SYNOPSIS
  10--------
  11[verse]
  12'git send-email' [options] <file|directory|rev-list options>...
  13
  14
  15DESCRIPTION
  16-----------
  17Takes the patches given on the command line and emails them out.
  18Patches can be specified as files, directories (which will send all
  19files in the directory), or directly as a revision list.  In the
  20last case, any format accepted by linkgit:git-format-patch[1] can
  21be passed to git send-email.
  22
  23The header of the email is configurable by command line options.  If not
  24specified on the command line, the user will be prompted with a ReadLine
  25enabled interface to provide the necessary information.
  26
  27There are two formats accepted for patch files:
  28
  291. mbox format files
  30+
  31This is what linkgit:git-format-patch[1] generates.  Most headers and MIME
  32formatting are ignored.
  33
  342. The original format used by Greg Kroah-Hartman's 'send_lots_of_email.pl'
  35script
  36+
  37This format expects the first line of the file to contain the "Cc:" value
  38and the "Subject:" of the message as the second line.

  41OPTIONS
  42-------
  43
  44Composing
  45~~~~~~~~~
  46
  47--annotate::
  48        Review and edit each patch you're about to send. Default is the value
  49        of 'sendemail.annotate'. See the CONFIGURATION section for
  50        'sendemail.multiedit'.
  51
  52--bcc=<address>::
  53        Specify a "Bcc:" value for each email. Default is the value of
  54        'sendemail.bcc'.
  55+
  56The --bcc option must be repeated for each user you want on the bcc list.
  57
  58--cc=<address>::
  59        Specify a starting "Cc:" value for each email.
  60        Default is the value of 'sendemail.cc'.
  61+
  62The --cc option must be repeated for each user you want on the cc list.
  63
  64--compose::
  65        Invoke a text editor (see GIT_EDITOR in linkgit:git-var[1])
  66        to edit an introductory message for the patch series.
  67+
  68When '--compose' is used, git send-email will use the From, Subject, and
  69In-Reply-To headers specified in the message. If the body of the message
  70(what you type after the headers and a blank line) only contains blank
  71(or Git: prefixed) lines the summary won't be sent, but From, Subject,
  72and In-Reply-To headers will be used unless they are removed.
  73+
  74Missing From or In-Reply-To headers will be prompted for.
  75+
  76See the CONFIGURATION section for 'sendemail.multiedit'.
  77
  78--from=<address>::
  79        Specify the sender of the emails.  If not specified on the command line,
  80        the value of the 'sendemail.from' configuration option is used.  If
  81        neither the command line option nor 'sendemail.from' are set, then the
  82        user will be prompted for the value.  The default for the prompt will be
  83        the value of GIT_AUTHOR_IDENT, or GIT_COMMITTER_IDENT if that is not
  84        set, as returned by "git var -l".
  85
  86--in-reply-to=<identifier>::
  87        Make the first mail (or all the mails with `--no-thread`) appear as a
  88        reply to the given Message-Id, which avoids breaking threads to
  89        provide a new patch series.
  90        The second and subsequent emails will be sent as replies according to
  91        the `--[no]-chain-reply-to` setting.
  92+
  93So for example when `--thread` and `--no-chain-reply-to` are specified, the
  94second and subsequent patches will be replies to the first one like in the
  95illustration below where `[PATCH v2 0/3]` is in reply to `[PATCH 0/2]`:
  96+
  97  [PATCH 0/2] Here is what I did...
  98    [PATCH 1/2] Clean up and tests
  99    [PATCH 2/2] Implementation
 100    [PATCH v2 0/3] Here is a reroll
 101      [PATCH v2 1/3] Clean up
 102      [PATCH v2 2/3] New tests
 103      [PATCH v2 3/3] Implementation
 104+
 105Only necessary if --compose is also set.  If --compose
 106is not set, this will be prompted for.
 107
 108--subject=<string>::
 109        Specify the initial subject of the email thread.
 110        Only necessary if --compose is also set.  If --compose
 111        is not set, this will be prompted for.
 112
 113--to=<address>::
 114        Specify the primary recipient of the emails generated. Generally, this
 115        will be the upstream maintainer of the project involved. Default is the
 116        value of the 'sendemail.to' configuration value; if that is unspecified,
 117        and --to-cmd is not specified, this will be prompted for.
 118+
 119The --to option must be repeated for each user you want on the to list.
 120
 121--8bit-encoding=<encoding>::
 122        When encountering a non-ASCII message or subject that does not
 123        declare its encoding, add headers/quoting to indicate it is
 124        encoded in <encoding>.  Default is the value of the
 125        'sendemail.assume8bitEncoding'; if that is unspecified, this
 126        will be prompted for if any non-ASCII files are encountered.
 127+
 128Note that no attempts whatsoever are made to validate the encoding.
 129
 130--compose-encoding=<encoding>::
 131        Specify encoding of compose message. Default is the value of the
 132        'sendemail.composeencoding'; if that is unspecified, UTF-8 is assumed.
 133
 134
 135Sending
 136~~~~~~~
 137
 138--envelope-sender=<address>::
 139        Specify the envelope sender used to send the emails.
 140        This is useful if your default address is not the address that is
 141        subscribed to a list. In order to use the 'From' address, set the
 142        value to "auto". If you use the sendmail binary, you must have
 143        suitable privileges for the -f parameter.  Default is the value of the
 144        'sendemail.envelopesender' configuration variable; if that is
 145        unspecified, choosing the envelope sender is left to your MTA.
 146
 147--smtp-encryption=<encryption>::
 148        Specify the encryption to use, either 'ssl' or 'tls'.  Any other
 149        value reverts to plain SMTP.  Default is the value of
 150        'sendemail.smtpencryption'.
 151
 152--smtp-domain=<FQDN>::
 153        Specifies the Fully Qualified Domain Name (FQDN) used in the
 154        HELO/EHLO command to the SMTP server.  Some servers require the
 155        FQDN to match your IP address.  If not set, git send-email attempts
 156        to determine your FQDN automatically.  Default is the value of
 157        'sendemail.smtpdomain'.
 158
 159--smtp-pass[=<password>]::
 160        Password for SMTP-AUTH. The argument is optional: If no
 161        argument is specified, then the empty string is used as
 162        the password. Default is the value of 'sendemail.smtppass',
 163        however '--smtp-pass' always overrides this value.
 164+
 165Furthermore, passwords need not be specified in configuration files
 166or on the command line. If a username has been specified (with
 167'--smtp-user' or a 'sendemail.smtpuser'), but no password has been
 168specified (with '--smtp-pass' or 'sendemail.smtppass'), then
 169a password is obtained using 'git-credential'.
 170
 171--smtp-server=<host>::
 172        If set, specifies the outgoing SMTP server to use (e.g.
 173        `smtp.example.com` or a raw IP address).  Alternatively it can
 174        specify a full pathname of a sendmail-like program instead;
 175        the program must support the `-i` option.  Default value can
 176        be specified by the 'sendemail.smtpserver' configuration
 177        option; the built-in default is `/usr/sbin/sendmail` or
 178        `/usr/lib/sendmail` if such program is available, or
 179        `localhost` otherwise.
 180
 181--smtp-server-port=<port>::
 182        Specifies a port different from the default port (SMTP
 183        servers typically listen to smtp port 25, but may also listen to
 184        submission port 587, or the common SSL smtp port 465);
 185        symbolic port names (e.g. "submission" instead of 587)
 186        are also accepted. The port can also be set with the
 187        'sendemail.smtpserverport' configuration variable.
 188
 189--smtp-server-option=<option>::
 190        If set, specifies the outgoing SMTP server option to use.
 191        Default value can be specified by the 'sendemail.smtpserveroption'
 192        configuration option.
 193+
 194The --smtp-server-option option must be repeated for each option you want
 195to pass to the server. Likewise, different lines in the configuration files
 196must be used for each option.
 197
 198--smtp-ssl::
 199        Legacy alias for '--smtp-encryption ssl'.
 200
 201--smtp-ssl-cert-path::
 202        Path to ca-certificates (either a directory or a single file).
 203        Set it to an empty string to disable certificate verification.
 204        Defaults to the value set to the 'sendemail.smtpsslcertpath'
 205        configuration variable, if set, or `/etc/ssl/certs` otherwise.
 206
 207--smtp-user=<user>::
 208        Username for SMTP-AUTH. Default is the value of 'sendemail.smtpuser';
 209        if a username is not specified (with '--smtp-user' or 'sendemail.smtpuser'),
 210        then authentication is not attempted.
 211
 212--smtp-debug=0|1::
 213        Enable (1) or disable (0) debug output. If enabled, SMTP
 214        commands and replies will be printed. Useful to debug TLS
 215        connection and authentication problems.
 216
 217Automating
 218~~~~~~~~~~
 219
 220--to-cmd=<command>::
 221        Specify a command to execute once per patch file which
 222        should generate patch file specific "To:" entries.
 223        Output of this command must be single email address per line.
 224        Default is the value of 'sendemail.tocmd' configuration value.
 225
 226--cc-cmd=<command>::
 227        Specify a command to execute once per patch file which
 228        should generate patch file specific "Cc:" entries.
 229        Output of this command must be single email address per line.
 230        Default is the value of 'sendemail.cccmd' configuration value.
 231
 232--[no-]chain-reply-to::
 233        If this is set, each email will be sent as a reply to the previous
 234        email sent.  If disabled with "--no-chain-reply-to", all emails after
 235        the first will be sent as replies to the first email sent.  When using
 236        this, it is recommended that the first file given be an overview of the
 237        entire patch series. Disabled by default, but the 'sendemail.chainreplyto'
 238        configuration variable can be used to enable it.
 239
 240--identity=<identity>::
 241        A configuration identity. When given, causes values in the
 242        'sendemail.<identity>' subsection to take precedence over
 243        values in the 'sendemail' section. The default identity is
 244        the value of 'sendemail.identity'.
 245
 246--[no-]signed-off-by-cc::
 247        If this is set, add emails found in Signed-off-by: or Cc: lines to the
 248        cc list. Default is the value of 'sendemail.signedoffbycc' configuration
 249        value; if that is unspecified, default to --signed-off-by-cc.
 250
 251--suppress-cc=<category>::
 252        Specify an additional category of recipients to suppress the
 253        auto-cc of:
 254+
 255--
 256- 'author' will avoid including the patch author
 257- 'self' will avoid including the sender
 258- 'cc' will avoid including anyone mentioned in Cc lines in the patch header
 259  except for self (use 'self' for that).
 260- 'bodycc' will avoid including anyone mentioned in Cc lines in the
 261  patch body (commit message) except for self (use 'self' for that).
 262- 'sob' will avoid including anyone mentioned in Signed-off-by lines except
 263   for self (use 'self' for that).
 264- 'cccmd' will avoid running the --cc-cmd.
 265- 'body' is equivalent to 'sob' + 'bodycc'
 266- 'all' will suppress all auto cc values.
 267--
 268+
 269Default is the value of 'sendemail.suppresscc' configuration value; if
 270that is unspecified, default to 'self' if --suppress-from is
 271specified, as well as 'body' if --no-signed-off-cc is specified.
 272
 273--[no-]suppress-from::
 274        If this is set, do not add the From: address to the cc: list.
 275        Default is the value of 'sendemail.suppressfrom' configuration
 276        value; if that is unspecified, default to --no-suppress-from.
 277
 278--[no-]thread::
 279        If this is set, the In-Reply-To and References headers will be
 280        added to each email sent.  Whether each mail refers to the
 281        previous email (`deep` threading per 'git format-patch'
 282        wording) or to the first email (`shallow` threading) is
 283        governed by "--[no-]chain-reply-to".
 284+
 285If disabled with "--no-thread", those headers will not be added
 286(unless specified with --in-reply-to).  Default is the value of the
 287'sendemail.thread' configuration value; if that is unspecified,
 288default to --thread.
 289+
 290It is up to the user to ensure that no In-Reply-To header already
 291exists when 'git send-email' is asked to add it (especially note that
 292'git format-patch' can be configured to do the threading itself).
 293Failure to do so may not produce the expected result in the
 294recipient's MUA.
 295

 297Administering
 298~~~~~~~~~~~~~
 299
 300--confirm=<mode>::
 301        Confirm just before sending:
 302+
 303--
 304- 'always' will always confirm before sending
 305- 'never' will never confirm before sending
 306- 'cc' will confirm before sending when send-email has automatically
 307  added addresses from the patch to the Cc list
 308- 'compose' will confirm before sending the first message when using --compose.
 309- 'auto' is equivalent to 'cc' + 'compose'
 310--
 311+
 312Default is the value of 'sendemail.confirm' configuration value; if that
 313is unspecified, default to 'auto' unless any of the suppress options
 314have been specified, in which case default to 'compose'.
 315
 316--dry-run::
 317        Do everything except actually send the emails.
 318
 319--[no-]format-patch::
 320        When an argument may be understood either as a reference or as a file name,
 321        choose to understand it as a format-patch argument ('--format-patch')
 322        or as a file name ('--no-format-patch'). By default, when such a conflict
 323        occurs, git send-email will fail.
 324
 325--quiet::
 326        Make git-send-email less verbose.  One line per email should be
 327        all that is output.
 328
 329--[no-]validate::
 330        Perform sanity checks on patches.
 331        Currently, validation means the following:
 332+
 333--
 334                *       Warn of patches that contain lines longer than 998 characters; this
 335                        is due to SMTP limits as described by http://www.ietf.org/rfc/rfc2821.txt.
 336--
 337+
 338Default is the value of 'sendemail.validate'; if this is not set,
 339default to '--validate'.
 340
 341--force::
 342        Send emails even if safety checks would prevent it.
 343
 344
 345CONFIGURATION
 346-------------
 347
 348sendemail.aliasesfile::
 349        To avoid typing long email addresses, point this to one or more
 350        email aliases files.  You must also supply 'sendemail.aliasfiletype'.
 351
 352sendemail.aliasfiletype::
 353        Format of the file(s) specified in sendemail.aliasesfile. Must be
 354        one of 'mutt', 'mailrc', 'pine', 'elm', or 'gnus'.
 355
 356sendemail.multiedit::
 357        If true (default), a single editor instance will be spawned to edit
 358        files you have to edit (patches when '--annotate' is used, and the
 359        summary when '--compose' is used). If false, files will be edited one
 360        after the other, spawning a new editor each time.
 361
 362sendemail.confirm::
 363        Sets the default for whether to confirm before sending. Must be
 364        one of 'always', 'never', 'cc', 'compose', or 'auto'. See '--confirm'
 365        in the previous section for the meaning of these values.
 366
 367EXAMPLE
 368-------
 369Use gmail as the smtp server
 370~~~~~~~~~~~~~~~~~~~~~~~~~~~~
 371To use 'git send-email' to send your patches through the GMail SMTP server,
 372edit ~/.gitconfig to specify your account settings:
 373
 374        [sendemail]
 375                smtpencryption = tls
 376                smtpserver = smtp.gmail.com
 377                smtpuser = yourname@gmail.com
 378                smtpserverport = 587
 379
 380Once your commits are ready to be sent to the mailing list, run the
 381following commands:
 382
 383        $ git format-patch --cover-letter -M origin/master -o outgoing/
 384        $ edit outgoing/0000-*
 385        $ git send-email outgoing/*
 386
 387Note: the following perl modules are required
