  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        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+
  85This was optional in prior versions of git, but now it is the
  86default.   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--ignore-space-change::
 103--ignore-whitespace::
 104--whitespace=<option>::
 105-C<n>::
 106-p<n>::
 107--directory=<dir>::
 108--exclude=<path>::
 109--include=<path>::
 110--reject::
 111        These flags are passed to the 'git apply' (see linkgit:git-apply[1])
 112        program that applies
 113        the patch.
 114
 115--patch-format::
 116        By default the command will try to detect the patch format
 117        automatically. This option allows the user to bypass the automatic
 118        detection and specify the patch format that the patch(es) should be
 119        interpreted as. Valid formats are mbox, stgit, stgit-series and hg.
 120
 121-i::
 122--interactive::
 123        Run interactively.
 124
 125--committer-date-is-author-date::
 126        By default the command records the date from the e-mail
 127        message as the commit author date, and uses the time of
 128        commit creation as the committer date. This allows the
 129        user to lie about the committer date by using the same
 130        value as the author date.
 131
 132--ignore-date::
 133        By default the command records the date from the e-mail
 134        message as the commit author date, and uses the time of
 135        commit creation as the committer date. This allows the
 136        user to lie about the author date by using the same
 137        value as the committer date.
 138
 139--skip::
 140        Skip the current patch.  This is only meaningful when
 141        restarting an aborted patch.
 142
 143-S[<keyid>]::
 144--gpg-sign[=<keyid>]::
 145        GPG-sign commits. The `keyid` argument is optional and
 146        defaults to the committer identity; if specified, it must be
 147        stuck to the option without a space.
 148
 149--continue::
 150-r::
 151--resolved::
 152        After a patch failure (e.g. attempting to apply
 153        conflicting patch), the user has applied it by hand and
 154        the index file stores the result of the application.
 155        Make a commit using the authorship and commit log
 156        extracted from the e-mail message and the current index
 157        file, and continue.
 158
 159--resolvemsg=<msg>::
 160        When a patch failure occurs, <msg> will be printed
 161        to the screen before exiting.  This overrides the
 162        standard message informing you to use `--continue`
 163        or `--skip` to handle the failure.  This is solely
 164        for internal use between 'git rebase' and 'git am'.
 165
 166--abort::
 167        Restore the original branch and abort the patching operation.
 168
 169DISCUSSION
 170----------
 171
 172The commit author name is taken from the "From: " line of the
 173message, and commit author date is taken from the "Date: " line
 174of the message.  The "Subject: " line is used as the title of
 175the commit, after stripping common prefix "[PATCH <anything>]".
 176The "Subject: " line is supposed to concisely describe what the
 177commit is about in one line of text.
 178
 179"From: " and "Subject: " lines starting the body override the respective
 180commit author name and title values taken from the headers.
 181
 182The commit message is formed by the title taken from the
 183"Subject: ", a blank line and the body of the message up to
 184where the patch begins.  Excess whitespace at the end of each
 185line is automatically stripped.
 186
 187The patch is expected to be inline, directly following the
 188message.  Any line that is of the form:
 189
 190* three-dashes and end-of-line, or
 191* a line that begins with "diff -", or
 192* a line that begins with "Index: "
 193
 194is taken as the beginning of a patch, and the commit log message
 195is terminated before the first occurrence of such a line.
 196
 197When initially invoking `git am`, you give it the names of the mailboxes
 198to process.  Upon seeing the first patch that does not apply, it
 199aborts in the middle.  You can recover from this in one of two ways:
 200
 201. skip the current patch by re-running the command with the '--skip'
 202  option.
 203
 204. hand resolve the conflict in the working directory, and update
 205  the index file to bring it into a state that the patch should
 206  have produced.  Then run the command with the '--continue' option.
 207
 208The command refuses to process new mailboxes until the current
 209operation is finished, so if you decide to start over from scratch,
 210run `git am --abort` before running the command with mailbox
 211names.
 212
 213Before any patches are applied, ORIG_HEAD is set to the tip of the
 214current branch.  This is useful if you have problems with multiple
 215commits, like running 'git am' on the wrong branch or an error in the
 216commits that is more easily fixed by changing the mailbox (e.g.
 217errors in the "From:" lines).
 218
 219HOOKS
 220-----
 221This command can run `applypatch-msg`, `pre-applypatch`,
