  21 DESCRIPTION
  22 -----------
  23 Splits mail messages in a mailbox into commit log message,
  24 authorship information and patches, and applies them to the
  25 current branch.
  26
  27 OPTIONS
  28 -------
  29 (<mbox>|<Maildir>)...::
  30         The list of mailbox files to read patches from. If you do not
  31         supply this argument, the command reads from the standard input.
  32         If you supply directories, they will be treated as Maildirs.
  33
  34 -s::
  35 --signoff::
  36         Add a `Signed-off-by:` line to the commit message, using
  37         the committer identity of yourself.
  38         See the signoff option in linkgit:git-commit[1] for more information.
  39
  40 -k::
  41 --keep::
  42         Pass `-k` flag to 'git mailinfo' (see linkgit:git-mailinfo[1]).
  43
  44 --keep-non-patch::
  45         Pass `-b` flag to 'git mailinfo' (see linkgit:git-mailinfo[1]).
  46
  47 --[no-]keep-cr::
  48         With `--keep-cr`, call 'git mailsplit' (see linkgit:git-mailsplit[1])
  49         with the same option, to prevent it from stripping CR at the end of
  50         lines. `am.keepcr` configuration variable can be used to specify the
  51         default behaviour.  `--no-keep-cr` is useful to override `am.keepcr`.
  52
  53 -c::
  54 --scissors::
  55         Remove everything in body before a scissors line (see
  56         linkgit:git-mailinfo[1]). Can be activated by default using
  57         the `mailinfo.scissors` configuration variable.
  58
  59 --no-scissors::
  60         Ignore scissors lines (see linkgit:git-mailinfo[1]).
  61
  62 -m::
  63 --message-id::
  64         Pass the `-m` flag to 'git mailinfo' (see linkgit:git-mailinfo[1]),
  65         so that the Message-ID header is added to the commit message.
  66         The `am.messageid` configuration variable can be used to specify
  67         the default behaviour.
  68
  69 --no-message-id::
  70         Do not add the Message-ID header to the commit message.
  71         `no-message-id` is useful to override `am.messageid`.
  72
  73 -q::
  74 --quiet::
  75         Be quiet. Only print error messages.
  76
  77 -u::
  78 --utf8::
  79         Pass `-u` flag to 'git mailinfo' (see linkgit:git-mailinfo[1]).
  80         The proposed commit log message taken from the e-mail
  81         is re-coded into UTF-8 encoding (configuration variable
  82         `i18n.commitencoding` can be used to specify project's
  83         preferred encoding if it is not UTF-8).
  84 +
  85 This was optional in prior versions of git, but now it is the
  86 default.   You can use `--no-utf8` to override this.
  87
  88 --no-utf8::
  89         Pass `-n` flag to 'git mailinfo' (see
  90         linkgit:git-mailinfo[1]).
  91
  92 -3::
  93 --3way::
  94 --no-3way::
  95         When the patch does not apply cleanly, fall back on
  96         3-way merge if the patch records the identity of blobs
  97         it is supposed to apply to and we have those blobs
  98         available locally. `--no-3way` can be used to override
  99         am.threeWay configuration variable. For more information,
 100         see am.threeWay in linkgit:git-config[1].
 101
 102 --rerere-autoupdate::
 103 --no-rerere-autoupdate::
 104         Allow the rerere mechanism to update the index with the
 105         result of auto-conflict resolution if possible.
 106
 107 --ignore-space-change::
 108 --ignore-whitespace::
 109 --whitespace=<option>::
 110 -C<n>::
 111 -p<n>::
 112 --directory=<dir>::
 113 --exclude=<path>::
 114 --include=<path>::
 115 --reject::
 116         These flags are passed to the 'git apply' (see linkgit:git-apply[1])
 117         program that applies
 118         the patch.
 119
 120 --patch-format::
 121         By default the command will try to detect the patch format
 122         automatically. This option allows the user to bypass the automatic
 123         detection and specify the patch format that the patch(es) should be
 124         interpreted as. Valid formats are mbox, mboxrd,
 125         stgit, stgit-series and hg.
 126
 127 -i::
 128 --interactive::
 129         Run interactively.
 130
 131 --committer-date-is-author-date::
 132         By default the command records the date from the e-mail
 133         message as the commit author date, and uses the time of
 134         commit creation as the committer date. This allows the
 135         user to lie about the committer date by using the same
 136         value as the author date.
 137
 138 --ignore-date::
 139         By default the command records the date from the e-mail
 140         message as the commit author date, and uses the time of
 141         commit creation as the committer date. This allows the
 142         user to lie about the author date by using the same
 143         value as the committer date.
 144
 145 --skip::
 146         Skip the current patch.  This is only meaningful when
 147         restarting an aborted patch.
 148
 149 -S[<keyid>]::
 150 --gpg-sign[=<keyid>]::
 151         GPG-sign commits. The `keyid` argument is optional and
 152         defaults to the committer identity; if specified, it must be
 153         stuck to the option without a space.
 154
 155 --continue::
 156 -r::
 157 --resolved::
 158         After a patch failure (e.g. attempting to apply
 159         conflicting patch), the user has applied it by hand and
 160         the index file stores the result of the application.
 161         Make a commit using the authorship and commit log
 162         extracted from the e-mail message and the current index
 163         file, and continue.
 164
 165 --resolvemsg=<msg>::
 166         When a patch failure occurs, <msg> will be printed
 167         to the screen before exiting.  This overrides the
 168         standard message informing you to use `--continue`
 169         or `--skip` to handle the failure.  This is solely
 170         for internal use between 'git rebase' and 'git am'.
 171
 172 --abort::
 173         Restore the original branch and abort the patching operation.
 174
 175 --quit::
 176         Abort the patching operation but keep HEAD and the index
 177         untouched.
 178
 179 --show-current-patch::
 180         Show the entire e-mail message "git am" has stopped at, because
 181         of conflicts.
 182
 183 DISCUSSION
 184 ----------
 185
 186 The commit author name is taken from the "From: " line of the
 187 message, and commit author date is taken from the "Date: " line
 188 of the message.  The "Subject: " line is used as the title of
 189 the commit, after stripping common prefix "[PATCH <anything>]".
 190 The "Subject: " line is supposed to concisely describe what the
 191 commit is about in one line of text.
 192
 193 "From: " and "Subject: " lines starting the body override the respective
 194 commit author name and title values taken from the headers.
 195
 196 The commit message is formed by the title taken from the
 197 "Subject: ", a blank line and the body of the message up to
 198 where the patch begins.  Excess whitespace at the end of each
 199 line is automatically stripped.
 200
 201 The patch is expected to be inline, directly following the
 202 message.  Any line that is of the form:
 203
 204 * three-dashes and end-of-line, or
 205 * a line that begins with "diff -", or
 206 * a line that begins with "Index: "
 207
 208 is taken as the beginning of a patch, and the commit log message
 209 is terminated before the first occurrence of such a line.
 210
 211 When initially invoking `git am`, you give it the names of the mailboxes
 212 to process.  Upon seeing the first patch that does not apply, it
 213 aborts in the middle.  You can recover from this in one of two ways:
 214
 215 . skip the current patch by re-running the command with the `--skip`
 216   option.
 217
 218 . hand resolve the conflict in the working directory, and update
 219   the index file to bring it into a state that the patch should
 220   have produced.  Then run the command with the `--continue` option.
 221
 222 The command refuses to process new mailboxes until the current
 223 operation is finished, so if you decide to start over from scratch,
 224 run `git am --abort` before running the command with mailbox
 225 names.
 226
 227 Before any patches are applied, ORIG_HEAD is set to the tip of the
 228 current branch.  This is useful if you have problems with multiple
 229 commits, like running 'git am' on the wrong branch or an error in the
 230 commits that is more easily fixed by changing the mailbox (e.g.
 231 errors in the "From:" lines).
