  21DESCRIPTION
  22-----------
  23Splits mail messages in a mailbox into commit log message,
  24authorship information and patches, and applies them to the
  25current branch.
  26
  27OPTIONS
  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
  39-k::
  40--keep::
  41        Pass `-k` flag to 'git mailinfo' (see linkgit:git-mailinfo[1]).
  42
  43--keep-non-patch::
  44        Pass `-b` flag to 'git mailinfo' (see linkgit:git-mailinfo[1]).
  45
  46--[no-]keep-cr::
  47        With `--keep-cr`, call 'git mailsplit' (see linkgit:git-mailsplit[1])
  48        with the same option, to prevent it from stripping CR at the end of
  49        lines. `am.keepcr` configuration variable can be used to specify the
  50        default behaviour.  `--no-keep-cr` is useful to override `am.keepcr`.
  51
  52-c::
  53--scissors::
  54        Remove everything in body before a scissors line (see
  55        linkgit:git-mailinfo[1]).
  56
  57--no-scissors::
  58        Ignore scissors lines (see linkgit:git-mailinfo[1]).
  59
  60-m::
  61--message-id::
  62        Pass the `-m` flag to 'git mailinfo' (see linkgit:git-mailinfo[1]),
  63        so that the Message-ID header is added to the commit message.
  64        The `am.messageid` configuration variable can be used to specify
  65        the default behaviour.
  66
  67--no-message-id::
  68        Do not add the Message-ID header to the commit message.
  69        `no-message-id` is useful to override `am.messageid`.
  70
  71-q::
  72--quiet::
  73        Be quiet. Only print error messages.
  74
  75-u::
  76--utf8::
  77        Pass `-u` flag to 'git mailinfo' (see linkgit:git-mailinfo[1]).
  78        The proposed commit log message taken from the e-mail
  79        is re-coded into UTF-8 encoding (configuration variable
  80        `i18n.commitencoding` can be used to specify project's
  81        preferred encoding if it is not UTF-8).
  82+
  83This was optional in prior versions of git, but now it is the
  84default.   You can use `--no-utf8` to override this.
  85
  86--no-utf8::
  87        Pass `-n` flag to 'git mailinfo' (see
  88        linkgit:git-mailinfo[1]).
  89
  90-3::
  91--3way::
  92        When the patch does not apply cleanly, fall back on
  93        3-way merge if the patch records the identity of blobs
  94        it is supposed to apply to and we have those blobs
  95        available locally.
  96
  97--ignore-space-change::
  98--ignore-whitespace::
  99--whitespace=<option>::
 100-C<n>::
 101-p<n>::
 102--directory=<dir>::
 103--exclude=<path>::
 104--include=<path>::
 105--reject::
 106        These flags are passed to the 'git apply' (see linkgit:git-apply[1])
 107        program that applies
 108        the patch.
 109
 110--patch-format::
 111        By default the command will try to detect the patch format
 112        automatically. This option allows the user to bypass the automatic
 113        detection and specify the patch format that the patch(es) should be
 114        interpreted as. Valid formats are mbox, stgit, stgit-series and hg.
 115
 116-i::
 117--interactive::
 118        Run interactively.
 119
 120--committer-date-is-author-date::
 121        By default the command records the date from the e-mail
 122        message as the commit author date, and uses the time of
 123        commit creation as the committer date. This allows the
 124        user to lie about the committer date by using the same
 125        value as the author date.
 126
 127--ignore-date::
 128        By default the command records the date from the e-mail
 129        message as the commit author date, and uses the time of
 130        commit creation as the committer date. This allows the
 131        user to lie about the author date by using the same
 132        value as the committer date.
 133
 134--skip::
 135        Skip the current patch.  This is only meaningful when
 136        restarting an aborted patch.
 137
 138-S[<keyid>]::
 139--gpg-sign[=<keyid>]::
 140        GPG-sign commits.
 141
 142--continue::
 143-r::
 144--resolved::
 145        After a patch failure (e.g. attempting to apply
 146        conflicting patch), the user has applied it by hand and
 147        the index file stores the result of the application.
 148        Make a commit using the authorship and commit log
 149        extracted from the e-mail message and the current index
 150        file, and continue.
 151
 152--resolvemsg=<msg>::
 153        When a patch failure occurs, <msg> will be printed
 154        to the screen before exiting.  This overrides the
 155        standard message informing you to use `--continue`
 156        or `--skip` to handle the failure.  This is solely
 157        for internal use between 'git rebase' and 'git am'.
 158
 159--abort::
 160        Restore the original branch and abort the patching operation.
 161
 162DISCUSSION
 163----------
 164
 165The commit author name is taken from the "From: " line of the
 166message, and commit author date is taken from the "Date: " line
 167of the message.  The "Subject: " line is used as the title of
 168the commit, after stripping common prefix "[PATCH <anything>]".
 169The "Subject: " line is supposed to concisely describe what the
 170commit is about in one line of text.
 171
 172"From: " and "Subject: " lines starting the body override the respective
 173commit author name and title values taken from the headers.
 174
 175The commit message is formed by the title taken from the
 176"Subject: ", a blank line and the body of the message up to
 177where the patch begins.  Excess whitespace at the end of each
 178line is automatically stripped.
 179
 180The patch is expected to be inline, directly following the
 181message.  Any line that is of the form:
 182
 183* three-dashes and end-of-line, or
 184* a line that begins with "diff -", or
 185* a line that begins with "Index: "
 186
 187is taken as the beginning of a patch, and the commit log message
 188is terminated before the first occurrence of such a line.
 189
 190When initially invoking `git am`, you give it the names of the mailboxes
 191to process.  Upon seeing the first patch that does not apply, it
 192aborts in the middle.  You can recover from this in one of two ways:
 193
 194. skip the current patch by re-running the command with the '--skip'
 195  option.
 196
 197. hand resolve the conflict in the working directory, and update
 198  the index file to bring it into a state that the patch should
 199  have produced.  Then run the command with the '--continue' option.
 200
 201The command refuses to process new mailboxes until the current
 202operation is finished, so if you decide to start over from scratch,
 203run `git am --abort` before running the command with mailbox
 204names.
 205
 206Before any patches are applied, ORIG_HEAD is set to the tip of the
 207current branch.  This is useful if you have problems with multiple
 208commits, like running 'git am' on the wrong branch or an error in the
 209commits that is more easily fixed by changing the mailbox (e.g.
 210errors in the "From:" lines).

 212HOOKS
 213-----
 214This command can run `applypatch-msg`, `pre-applypatch`,
 215and `post-applypatch` hooks.  See linkgit:githooks[5] for more
