  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, mboxrd,
 120        stgit, stgit-series and hg.
 121
 122-i::
 123--interactive::
 124        Run interactively.
 125
 126--committer-date-is-author-date::
 127        By default the command records the date from the e-mail
 128        message as the commit author date, and uses the time of
 129        commit creation as the committer date. This allows the
 130        user to lie about the committer date by using the same
 131        value as the author date.
 132
 133--ignore-date::
 134        By default the command records the date from the e-mail
 135        message as the commit author date, and uses the time of
 136        commit creation as the committer date. This allows the
 137        user to lie about the author date by using the same
 138        value as the committer date.
 139
 140--skip::
 141        Skip the current patch.  This is only meaningful when
 142        restarting an aborted patch.
 143
 144-S[<keyid>]::
 145--gpg-sign[=<keyid>]::
 146        GPG-sign commits. The `keyid` argument is optional and
 147        defaults to the committer identity; if specified, it must be
 148        stuck to the option without a space.
 149
 150--continue::
 151-r::
 152--resolved::
 153        After a patch failure (e.g. attempting to apply
 154        conflicting patch), the user has applied it by hand and
 155        the index file stores the result of the application.
 156        Make a commit using the authorship and commit log
 157        extracted from the e-mail message and the current index
 158        file, and continue.
 159
 160--resolvemsg=<msg>::
 161        When a patch failure occurs, <msg> will be printed
 162        to the screen before exiting.  This overrides the
 163        standard message informing you to use `--continue`
 164        or `--skip` to handle the failure.  This is solely
 165        for internal use between 'git rebase' and 'git am'.
 166
 167--abort::
 168        Restore the original branch and abort the patching operation.
 169
 170--quit::
 171        Abort the patching operation but keep HEAD and the index
 172        untouched.
 173
 174--show-current-patch::
 175        Show the patch being applied when "git am" is stopped because
 176        of conflicts.
 177
 178DISCUSSION
 179----------
 180
 181The commit author name is taken from the "From: " line of the
 182message, and commit author date is taken from the "Date: " line
 183of the message.  The "Subject: " line is used as the title of
 184the commit, after stripping common prefix "[PATCH <anything>]".
 185The "Subject: " line is supposed to concisely describe what the
 186commit is about in one line of text.
 187
 188"From: " and "Subject: " lines starting the body override the respective
 189commit author name and title values taken from the headers.
 190
 191The commit message is formed by the title taken from the
 192"Subject: ", a blank line and the body of the message up to
 193where the patch begins.  Excess whitespace at the end of each
 194line is automatically stripped.
 195
 196The patch is expected to be inline, directly following the
 197message.  Any line that is of the form:
 198
 199* three-dashes and end-of-line, or
 200* a line that begins with "diff -", or
 201* a line that begins with "Index: "
 202
 203is taken as the beginning of a patch, and the commit log message
 204is terminated before the first occurrence of such a line.
 205
 206When initially invoking `git am`, you give it the names of the mailboxes
 207to process.  Upon seeing the first patch that does not apply, it
 208aborts in the middle.  You can recover from this in one of two ways:
 209
 210. skip the current patch by re-running the command with the `--skip`
 211  option.
 212
 213. hand resolve the conflict in the working directory, and update
 214  the index file to bring it into a state that the patch should
 215  have produced.  Then run the command with the `--continue` option.
 216
 217The command refuses to process new mailboxes until the current
 218operation is finished, so if you decide to start over from scratch,
 219run `git am --abort` before running the command with mailbox
 220names.
 221
 222Before any patches are applied, ORIG_HEAD is set to the tip of the
 223current branch.  This is useful if you have problems with multiple
 224commits, like running 'git am' on the wrong branch or an error in the
 225commits that is more easily fixed by changing the mailbox (e.g.
 226errors in the "From:" lines).

 228HOOKS
 229-----
 230This command can run `applypatch-msg`, `pre-applypatch`,
