  19DESCRIPTION
  20-----------
  21
  22Prepare each commit between <since> and <until> with its patch in
  23one file per commit, formatted to resemble UNIX mailbox format.
  24If ..<until> is not specified, the head of the current working
  25tree is implied.  For a more complete list of ways to spell
  26<since> and <until>, see "SPECIFYING REVISIONS" section in
  27gitlink:git-rev-parse[1].
  28
  29The output of this command is convenient for e-mail submission or
  30for use with gitlink:git-am[1].
  31
  32Each output file is numbered sequentially from 1, and uses the
  33first line of the commit message (massaged for pathname safety) as
  34the filename. The names of the output files are printed to standard
  35output, unless the --stdout option is specified.
  36
  37If -o is specified, output files are created in <dir>.  Otherwise
  38they are created in the current working directory.
  39
  40If -n is specified, instead of "[PATCH] Subject", the first line
  41is formatted as "[PATCH n/m] Subject".
  42
  43If given --thread, git-format-patch will generate In-Reply-To and
  44References headers to make the second and subsequent patch mails appear
  45as replies to the first mail; this also generates a Message-Id header to
  46reference.
  47
  48OPTIONS
  49-------
  50include::diff-options.txt[]
  51
  52-o|--output-directory <dir>::
  53        Use <dir> to store the resulting files, instead of the
  54        current working directory.
  55
  56-n|--numbered::
  57        Name output in '[PATCH n/m]' format.
  58
  59--start-number <n>::
  60        Start numbering the patches at <n> instead of 1.
  61
  62-k|--keep-subject::
  63        Do not strip/add '[PATCH]' from the first line of the
  64        commit log message.
  65
  66-s|--signoff::
  67        Add `Signed-off-by:` line to the commit message, using
  68        the committer identity of yourself.
  69
  70--stdout::
  71        Print all commits to the standard output in mbox format,
  72        instead of creating a file for each one.
  73
  74--attach[=<boundary>]::
  75        Create multipart/mixed attachment, the first part of
  76        which is the commit message and the patch itself in the
  77        second part, with "Content-Disposition: attachment".
  78
  79--inline[=<boundary>]::
  80        Create multipart/mixed attachment, the first part of
  81        which is the commit message and the patch itself in the
  82        second part, with "Content-Disposition: inline".
  83
  84--thread::
  85        Add In-Reply-To and References headers to make the second and
  86        subsequent mails appear as replies to the first.  Also generates
  87        the Message-Id header to reference.
  88
  89--in-reply-to=Message-Id::
  90        Make the first mail (or all the mails with --no-thread) appear as a
  91        reply to the given Message-Id, which avoids breaking threads to
  92        provide a new patch series.
  93
  94--ignore-if-in-upstream::
  95        Do not include a patch that matches a commit in
  96        <until>..<since>.  This will examine all patches reachable
  97        from <since> but not from <until> and compare them with the
  98        patches being generated, and any patch that matches is
  99        ignored.
 100
 101--suffix=.<sfx>::
 102        Instead of using `.patch` as the suffix for generated
 103        filenames, use specifed suffix.  A common alternative is
 104        `--suffix=.txt`.
 105+
 106Note that you would need to include the leading dot `.` if you
 107want a filename like `0001-description-of-my-change.patch`, and
 108the first letter does not have to be a dot.  Leaving it empty would
 109not add any suffix.
 110
 111CONFIGURATION
 112-------------
 113You can specify extra mail header lines to be added to each
 114message in the repository configuration.  Also you can specify
 115the default suffix different from the built-in one:
 116
 117------------
 118[format]
 119        headers = "Organization: git-foo\n"
 120        suffix = .txt
 121------------
 122
 123
 124EXAMPLES
 125--------
 126
 127git-format-patch -k --stdout R1..R2 | git-am -3 -k::
 128        Extract commits between revisions R1 and R2, and apply
 129        them on top of the current branch using `git-am` to
 130        cherry-pick them.
 131
 132git-format-patch origin::
 133        Extract all commits which are in the current branch but
 134        not in the origin branch.  For each commit a separate file
 135        is created in the current directory.
 136
 137git-format-patch -M -B origin::
 138        The same as the previous one.  Additionally, it detects
 139        and handles renames and complete rewrites intelligently to
 140        produce a renaming patch.  A renaming patch reduces the
 141        amount of text output, and generally makes it easier to
 142        review it.  Note that the "patch" program does not
 143        understand renaming patches, so use it only when you know
 144        the recipient uses git to apply your patch.
 145
 146git-format-patch -3::
 147        Extract three topmost commits from the current branch
 148        and format them as e-mailable patches.
