1git-send-email(1) 2================= 3 4NAME 5---- 6git-send-email - Send a collection of patches as emails 7 8 9SYNOPSIS 10-------- 11[verse] 12'git send-email' [options] <file|directory|rev-list options>... 13'git send-email' --dump-aliases 14 15 16DESCRIPTION 17----------- 18Takes the patches given on the command line and emails them out. 19Patches can be specified as files, directories (which will send all 20files in the directory), or directly as a revision list. In the 21last case, any format accepted by linkgit:git-format-patch[1] can 22be passed to git send-email. 23 24The header of the email is configurable via command-line options. If not 25specified on the command line, the user will be prompted with a ReadLine 26enabled interface to provide the necessary information. 27 28There are two formats accepted for patch files: 29 301. mbox format files 31+ 32This is what linkgit:git-format-patch[1] generates. Most headers and MIME 33formatting are ignored. 34 352. The original format used by Greg Kroah-Hartman's 'send_lots_of_email.pl' 36script 37+ 38This format expects the first line of the file to contain the "Cc:" value 39and the "Subject:" of the message as the second line. 40 41 42OPTIONS 43------- 44 45Composing 46~~~~~~~~~ 47 48--annotate:: 49 Review and edit each patch you're about to send. Default is the value 50 of 'sendemail.annotate'. See the CONFIGURATION section for 51 'sendemail.multiEdit'. 52 53--bcc=<address>,...:: 54 Specify a "Bcc:" value for each email. Default is the value of 55 'sendemail.bcc'. 56+ 57This option may be specified multiple times. 58 59--cc=<address>,...:: 60 Specify a starting "Cc:" value for each email. 61 Default is the value of 'sendemail.cc'. 62+ 63This option may be specified multiple times. 64 65--compose:: 66 Invoke a text editor (see GIT_EDITOR in linkgit:git-var[1]) 67 to edit an introductory message for the patch series. 68+ 69When '--compose' is used, git send-email will use the From, Subject, and 70In-Reply-To headers specified in the message. If the body of the message 71(what you type after the headers and a blank line) only contains blank 72(or Git: prefixed) lines, the summary won't be sent, but From, Subject, 73and In-Reply-To headers will be used unless they are removed. 74+ 75Missing From or In-Reply-To headers will be prompted for. 76+ 77See the CONFIGURATION section for 'sendemail.multiEdit'. 78 79--from=<address>:: 80 Specify the sender of the emails. If not specified on the command line, 81 the value of the 'sendemail.from' configuration option is used. If 82 neither the command-line option nor 'sendemail.from' are set, then the 83 user will be prompted for the value. The default for the prompt will be 84 the value of GIT_AUTHOR_IDENT, or GIT_COMMITTER_IDENT if that is not 85 set, as returned by "git var -l". 86 87--in-reply-to=<identifier>:: 88 Make the first mail (or all the mails with `--no-thread`) appear as a 89 reply to the given Message-Id, which avoids breaking threads to 90 provide a new patch series. 91 The second and subsequent emails will be sent as replies according to 92 the `--[no]-chain-reply-to` setting. 93+ 94So for example when `--thread` and `--no-chain-reply-to` are specified, the 95second and subsequent patches will be replies to the first one like in the 96illustration below where `[PATCH v2 0/3]` is in reply to `[PATCH 0/2]`: 97+ 98 [PATCH 0/2] Here is what I did... 99 [PATCH 1/2] Clean up and tests 100 [PATCH 2/2] Implementation 101 [PATCH v2 0/3] Here is a reroll 102 [PATCH v2 1/3] Clean up 103 [PATCH v2 2/3] New tests 104 [PATCH v2 3/3] Implementation 105+ 106Only necessary if --compose is also set. If --compose 107is not set, this will be prompted for. 108 109--subject=<string>:: 110 Specify the initial subject of the email thread. 111 Only necessary if --compose is also set. If --compose 112 is not set, this will be prompted for. 113 114--to=<address>,...:: 115 Specify the primary recipient of the emails generated. Generally, this 116 will be the upstream maintainer of the project involved. Default is the 117 value of the 'sendemail.to' configuration value; if that is unspecified, 118 and --to-cmd is not specified, this will be prompted for. 119+ 120This option may be specified multiple times. 121 122--8bit-encoding=<encoding>:: 123 When encountering a non-ASCII message or subject that does not 124 declare its encoding, add headers/quoting to indicate it is 125 encoded in <encoding>. Default is the value of the 126 'sendemail.assume8bitEncoding'; if that is unspecified, this 127 will be prompted for if any non-ASCII files are encountered. 128+ 129Note that no attempts whatsoever are made to validate the encoding. 130 131--compose-encoding=<encoding>:: 132 Specify encoding of compose message. Default is the value of the 133 'sendemail.composeencoding'; if that is unspecified, UTF-8 is assumed. 134 135--transfer-encoding=(7bit|8bit|quoted-printable|base64):: 136 Specify the transfer encoding to be used to send the message over SMTP. 137 7bit will fail upon encountering a non-ASCII message. quoted-printable 138 can be useful when the repository contains files that contain carriage 139 returns, but makes the raw patch email file (as saved from a MUA) much 140 harder to inspect manually. base64 is even more fool proof, but also 141 even more opaque. Default is the value of the 'sendemail.transferEncoding' 142 configuration value; if that is unspecified, git will use 8bit and not 143 add a Content-Transfer-Encoding header. 144 145--xmailer:: 146--no-xmailer:: 147 Add (or prevent adding) the "X-Mailer:" header. By default, 148 the header is added, but it can be turned off by setting the 149 `sendemail.xmailer` configuration variable to `false`. 150 151Sending 152~~~~~~~ 153 154--envelope-sender=<address>:: 155 Specify the envelope sender used to send the emails. 156 This is useful if your default address is not the address that is 157 subscribed to a list. In order to use the 'From' address, set the 158 value to "auto". If you use the sendmail binary, you must have 159 suitable privileges for the -f parameter. Default is the value of the 160 'sendemail.envelopeSender' configuration variable; if that is 161 unspecified, choosing the envelope sender is left to your MTA. 162 163--smtp-encryption=<encryption>:: 164 Specify the encryption to use, either 'ssl' or 'tls'. Any other 165 value reverts to plain SMTP. Default is the value of 166 'sendemail.smtpEncryption'. 167 168--smtp-domain=<FQDN>:: 169 Specifies the Fully Qualified Domain Name (FQDN) used in the 170 HELO/EHLO command to the SMTP server. Some servers require the 171 FQDN to match your IP address. If not set, git send-email attempts 172 to determine your FQDN automatically. Default is the value of 173 'sendemail.smtpDomain'. 174 175--smtp-auth=<mechanisms>:: 176 Whitespace-separated list of allowed SMTP-AUTH mechanisms. This setting 177 forces using only the listed mechanisms. Example: 178+ 179------ 180$ git send-email --smtp-auth="PLAIN LOGIN GSSAPI" ... 181------ 182+ 183If at least one of the specified mechanisms matches the ones advertised by the 184SMTP server and if it is supported by the utilized SASL library, the mechanism 185is used for authentication. If neither 'sendemail.smtpAuth' nor '--smtp-auth' 186is specified, all mechanisms supported by the SASL library can be used. 187 188--smtp-pass[=<password>]:: 189 Password for SMTP-AUTH. The argument is optional: If no 190 argument is specified, then the empty string is used as 191 the password. Default is the value of 'sendemail.smtpPass', 192 however '--smtp-pass' always overrides this value. 193+ 194Furthermore, passwords need not be specified in configuration files 195or on the command line. If a username has been specified (with 196'--smtp-user' or a 'sendemail.smtpUser'), but no password has been 197specified (with '--smtp-pass' or 'sendemail.smtpPass'), then 198a password is obtained using 'git-credential'. 199 200--smtp-server=<host>:: 201 If set, specifies the outgoing SMTP server to use (e.g. 202 `smtp.example.com` or a raw IP address). Alternatively it can 203 specify a full pathname of a sendmail-like program instead; 204 the program must support the `-i` option. Default value can 205 be specified by the 'sendemail.smtpServer' configuration 206 option; the built-in default is `/usr/sbin/sendmail` or 207 `/usr/lib/sendmail` if such program is available, or 208 `localhost` otherwise. 209 210--smtp-server-port=<port>:: 211 Specifies a port different from the default port (SMTP 212 servers typically listen to smtp port 25, but may also listen to 213 submission port 587, or the common SSL smtp port 465); 214 symbolic port names (e.g. "submission" instead of 587) 215 are also accepted. The port can also be set with the 216 'sendemail.smtpServerPort' configuration variable. 217 218--smtp-server-option=<option>:: 219 If set, specifies the outgoing SMTP server option to use. 220 Default value can be specified by the 'sendemail.smtpServerOption' 221 configuration option. 222+ 223The --smtp-server-option option must be repeated for each option you want 224to pass to the server. Likewise, different lines in the configuration files 225must be used for each option. 226 227--smtp-ssl:: 228 Legacy alias for '--smtp-encryption ssl'. 229 230--smtp-ssl-cert-path:: 231 Path to a store of trusted CA certificates for SMTP SSL/TLS 232 certificate validation (either a directory that has been processed 233 by 'c_rehash', or a single file containing one or more PEM format 234 certificates concatenated together: see verify(1) -CAfile and 235 -CApath for more information on these). Set it to an empty string 236 to disable certificate verification. Defaults to the value of the 237 'sendemail.smtpsslcertpath' configuration variable, if set, or the 238 backing SSL library's compiled-in default otherwise (which should 239 be the best choice on most platforms). 240 241--smtp-user=<user>:: 242 Username for SMTP-AUTH. Default is the value of 'sendemail.smtpUser'; 243 if a username is not specified (with '--smtp-user' or 'sendemail.smtpUser'), 244 then authentication is not attempted. 245 246--smtp-debug=0|1:: 247 Enable (1) or disable (0) debug output. If enabled, SMTP 248 commands and replies will be printed. Useful to debug TLS 249 connection and authentication problems. 250 251Automating 252~~~~~~~~~~ 253 254--to-cmd=<command>:: 255 Specify a command to execute once per patch file which 256 should generate patch file specific "To:" entries. 257 Output of this command must be single email address per line. 258 Default is the value of 'sendemail.tocmd' configuration value. 259 260--cc-cmd=<command>:: 261 Specify a command to execute once per patch file which 262 should generate patch file specific "Cc:" entries. 263 Output of this command must be single email address per line. 264 Default is the value of 'sendemail.ccCmd' configuration value. 265 266--[no-]chain-reply-to:: 267 If this is set, each email will be sent as a reply to the previous 268 email sent. If disabled with "--no-chain-reply-to", all emails after 269 the first will be sent as replies to the first email sent. When using 270 this, it is recommended that the first file given be an overview of the 271 entire patch series. Disabled by default, but the 'sendemail.chainReplyTo' 272 configuration variable can be used to enable it. 273 274--identity=<identity>:: 275 A configuration identity. When given, causes values in the 276 'sendemail.<identity>' subsection to take precedence over 277 values in the 'sendemail' section. The default identity is 278 the value of 'sendemail.identity'. 279 280--[no-]signed-off-by-cc:: 281 If this is set, add emails found in Signed-off-by: or Cc: lines to the 282 cc list. Default is the value of 'sendemail.signedoffbycc' configuration 283 value; if that is unspecified, default to --signed-off-by-cc. 284 285--[no-]cc-cover:: 286 If this is set, emails found in Cc: headers in the first patch of 287 the series (typically the cover letter) are added to the cc list 288 for each email set. Default is the value of 'sendemail.cccover' 289 configuration value; if that is unspecified, default to --no-cc-cover. 290 291--[no-]to-cover:: 292 If this is set, emails found in To: headers in the first patch of 293 the series (typically the cover letter) are added to the to list 294 for each email set. Default is the value of 'sendemail.tocover' 295 configuration value; if that is unspecified, default to --no-to-cover. 296 297--suppress-cc=<category>:: 298 Specify an additional category of recipients to suppress the 299 auto-cc of: 300+ 301-- 302- 'author' will avoid including the patch author 303- 'self' will avoid including the sender 304- 'cc' will avoid including anyone mentioned in Cc lines in the patch header 305 except for self (use 'self' for that). 306- 'bodycc' will avoid including anyone mentioned in Cc lines in the 307 patch body (commit message) except for self (use 'self' for that). 308- 'sob' will avoid including anyone mentioned in Signed-off-by lines except 309 for self (use 'self' for that). 310- 'cccmd' will avoid running the --cc-cmd. 311- 'body' is equivalent to 'sob' + 'bodycc' 312- 'all' will suppress all auto cc values. 313-- 314+ 315Default is the value of 'sendemail.suppresscc' configuration value; if 316that is unspecified, default to 'self' if --suppress-from is 317specified, as well as 'body' if --no-signed-off-cc is specified. 318 319--[no-]suppress-from:: 320 If this is set, do not add the From: address to the cc: list. 321 Default is the value of 'sendemail.suppressFrom' configuration 322 value; if that is unspecified, default to --no-suppress-from. 323 324--[no-]thread:: 325 If this is set, the In-Reply-To and References headers will be 326 added to each email sent. Whether each mail refers to the 327 previous email (`deep` threading per 'git format-patch' 328 wording) or to the first email (`shallow` threading) is 329 governed by "--[no-]chain-reply-to". 330+ 331If disabled with "--no-thread", those headers will not be added 332(unless specified with --in-reply-to). Default is the value of the 333'sendemail.thread' configuration value; if that is unspecified, 334default to --thread. 335+ 336It is up to the user to ensure that no In-Reply-To header already 337exists when 'git send-email' is asked to add it (especially note that 338'git format-patch' can be configured to do the threading itself). 339Failure to do so may not produce the expected result in the 340recipient's MUA. 341 342 343Administering 344~~~~~~~~~~~~~ 345 346--confirm=<mode>:: 347 Confirm just before sending: 348+ 349-- 350- 'always' will always confirm before sending 351- 'never' will never confirm before sending 352- 'cc' will confirm before sending when send-email has automatically 353 added addresses from the patch to the Cc list 354- 'compose' will confirm before sending the first message when using --compose. 355- 'auto' is equivalent to 'cc' + 'compose' 356-- 357+ 358Default is the value of 'sendemail.confirm' configuration value; if that 359is unspecified, default to 'auto' unless any of the suppress options 360have been specified, in which case default to 'compose'. 361 362--dry-run:: 363 Do everything except actually send the emails. 364 365--[no-]format-patch:: 366 When an argument may be understood either as a reference or as a file name, 367 choose to understand it as a format-patch argument ('--format-patch') 368 or as a file name ('--no-format-patch'). By default, when such a conflict 369 occurs, git send-email will fail. 370 371--quiet:: 372 Make git-send-email less verbose. One line per email should be 373 all that is output. 374 375--[no-]validate:: 376 Perform sanity checks on patches. 377 Currently, validation means the following: 378+ 379-- 380 * Warn of patches that contain lines longer than 998 characters; this 381 is due to SMTP limits as described by http://www.ietf.org/rfc/rfc2821.txt. 382-- 383+ 384Default is the value of 'sendemail.validate'; if this is not set, 385default to '--validate'. 386 387--force:: 388 Send emails even if safety checks would prevent it. 389 390 391Information 392~~~~~~~~~~~ 393 394--dump-aliases:: 395 Instead of the normal operation, dump the shorthand alias names from 396 the configured alias file(s), one per line in alphabetical order. Note, 397 this only includes the alias name and not its expanded email addresses. 398 See 'sendemail.aliasesfile' for more information about aliases. 399 400 401CONFIGURATION 402------------- 403 404sendemail.aliasesFile:: 405 To avoid typing long email addresses, point this to one or more 406 email aliases files. You must also supply 'sendemail.aliasFileType'. 407 408sendemail.aliasFileType:: 409 Format of the file(s) specified in sendemail.aliasesFile. Must be 410 one of 'mutt', 'mailrc', 'pine', 'elm', or 'gnus', or 'sendmail'. 411+ 412What an alias file in each format looks like can be found in 413the documentation of the email program of the same name. The 414differences and limitations from the standard formats are 415described below: 416+ 417-- 418sendmail;; 419* Quoted aliases and quoted addresses are not supported: lines that 420 contain a `"` symbol are ignored. 421* Redirection to a file (`/path/name`) or pipe (`|command`) is not 422 supported. 423* File inclusion (`:include: /path/name`) is not supported. 424* Warnings are printed on the standard error output for any 425 explicitly unsupported constructs, and any other lines that are not 426 recognized by the parser. 427-- 428 429sendemail.multiEdit:: 430 If true (default), a single editor instance will be spawned to edit 431 files you have to edit (patches when '--annotate' is used, and the 432 summary when '--compose' is used). If false, files will be edited one 433 after the other, spawning a new editor each time. 434 435sendemail.confirm:: 436 Sets the default for whether to confirm before sending. Must be 437 one of 'always', 'never', 'cc', 'compose', or 'auto'. See '--confirm' 438 in the previous section for the meaning of these values. 439 440EXAMPLE 441------- 442Use gmail as the smtp server 443~~~~~~~~~~~~~~~~~~~~~~~~~~~~ 444To use 'git send-email' to send your patches through the GMail SMTP server, 445edit ~/.gitconfig to specify your account settings: 446 447 [sendemail] 448 smtpEncryption = tls 449 smtpServer = smtp.gmail.com 450 smtpUser = yourname@gmail.com 451 smtpServerPort = 587 452 453Once your commits are ready to be sent to the mailing list, run the 454following commands: 455 456 $ git format-patch --cover-letter -M origin/master -o outgoing/ 457 $ edit outgoing/0000-* 458 $ git send-email outgoing/* 459 460Note: the following perl modules are required 461 Net::SMTP::SSL, MIME::Base64 and Authen::SASL 462 463SEE ALSO 464-------- 465linkgit:git-format-patch[1], linkgit:git-imap-send[1], mbox(5) 466 467GIT 468--- 469Part of the linkgit:git[1] suite
