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