  21DESCRIPTION
  22-----------
  23
  24Prepare each commit between <since> and <until> with its patch in
  25one file per commit, formatted to resemble UNIX mailbox format.
  26If ..<until> is not specified, the head of the current working
  27tree is implied.  For a more complete list of ways to spell
  28<since> and <until>, see "SPECIFYING REVISIONS" section in
  29gitlink:git-rev-parse[1].
  30
  31The output of this command is convenient for e-mail submission or
  32for use with gitlink:git-am[1].
  33
  34By default, each output file is numbered sequentially from 1, and uses the
  35first line of the commit message (massaged for pathname safety) as
  36the filename. With the --numbered-files option, the output file names
  37will only be numbers, without the first line of the commit appended.
  38The names of the output files are printed to standard
  39output, unless the --stdout option is specified.
  40
  41If -o is specified, output files are created in <dir>.  Otherwise
  42they are created in the current working directory.
  43
  44If -n is specified, instead of "[PATCH] Subject", the first line
  45is formatted as "[PATCH n/m] Subject".
  46
  47If given --thread, git-format-patch will generate In-Reply-To and
  48References headers to make the second and subsequent patch mails appear
  49as replies to the first mail; this also generates a Message-Id header to
  50reference.
  51
  52OPTIONS
  53-------
  54include::diff-options.txt[]
  55
  56-<n>::
  57        Limits the number of patches to prepare.
  58
  59-o|--output-directory <dir>::
  60        Use <dir> to store the resulting files, instead of the
  61        current working directory.
  62
  63-n|--numbered::
  64        Name output in '[PATCH n/m]' format.
  65
  66--start-number <n>::
  67        Start numbering the patches at <n> instead of 1.
  68
  69--numbered-files::
  70        Output file names will be a simple number sequence
  71        without the default first line of the commit appended.
  72        Mutually exclusive with the --stdout option.
  73
  74-k|--keep-subject::
  75        Do not strip/add '[PATCH]' from the first line of the
  76        commit log message.
  77
  78-s|--signoff::
  79        Add `Signed-off-by:` line to the commit message, using
  80        the committer identity of yourself.
  81
  82--stdout::
  83        Print all commits to the standard output in mbox format,
  84        instead of creating a file for each one.
  85
  86--attach[=<boundary>]::
  87        Create multipart/mixed attachment, the first part of
  88        which is the commit message and the patch itself in the
  89        second part, with "Content-Disposition: attachment".
  90
  91--inline[=<boundary>]::
  92        Create multipart/mixed attachment, the first part of
  93        which is the commit message and the patch itself in the
  94        second part, with "Content-Disposition: inline".
  95
  96--thread::
  97        Add In-Reply-To and References headers to make the second and
  98        subsequent mails appear as replies to the first.  Also generates
  99        the Message-Id header to reference.
 100
 101--in-reply-to=Message-Id::
 102        Make the first mail (or all the mails with --no-thread) appear as a
 103        reply to the given Message-Id, which avoids breaking threads to
 104        provide a new patch series.
 105
 106--ignore-if-in-upstream::
 107        Do not include a patch that matches a commit in
 108        <until>..<since>.  This will examine all patches reachable
 109        from <since> but not from <until> and compare them with the
 110        patches being generated, and any patch that matches is
 111        ignored.
 112
 113--subject-prefix=<Subject-Prefix>::
 114        Instead of the standard '[PATCH]' prefix in the subject
 115        line, instead use '[<Subject-Prefix>]'. This
 116        allows for useful naming of a patch series, and can be
 117        combined with the --numbered option.
 118
 119--suffix=.<sfx>::
 120        Instead of using `.patch` as the suffix for generated
 121        filenames, use specifed suffix.  A common alternative is
 122        `--suffix=.txt`.
 123+
 124Note that you would need to include the leading dot `.` if you
 125want a filename like `0001-description-of-my-change.patch`, and
 126the first letter does not have to be a dot.  Leaving it empty would
 127not add any suffix.
 128
 129CONFIGURATION
 130-------------
 131You can specify extra mail header lines to be added to each
 132message in the repository configuration.  You can also specify
 133new defaults for the subject prefix and file suffix.
 134
 135------------
 136[format]
 137        headers = "Organization: git-foo\n"
 138        subjectprefix = CHANGE
 139        suffix = .txt

 143EXAMPLES
 144--------
 145
 146git-format-patch -k --stdout R1..R2 | git-am -3 -k::
 147        Extract commits between revisions R1 and R2, and apply
 148        them on top of the current branch using `git-am` to
 149        cherry-pick them.
 150
 151git-format-patch origin::
 152        Extract all commits which are in the current branch but
 153        not in the origin branch.  For each commit a separate file
 154        is created in the current directory.
 155
 156git-format-patch -M -B origin::
 157        The same as the previous one.  Additionally, it detects
 158        and handles renames and complete rewrites intelligently to
 159        produce a renaming patch.  A renaming patch reduces the
 160        amount of text output, and generally makes it easier to
 161        review it.  Note that the "patch" program does not
 162        understand renaming patches, so use it only when you know
 163        the recipient uses git to apply your patch.
 164
 165git-format-patch -3::
 166        Extract three topmost commits from the current branch
 167        and format them as e-mailable patches.
