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