6 git-format-patch - Prepare patches for e-mail submission
12 'git-format-patch' [<common diff options>] [-n | -k] [-o <dir> | --stdout]
13 [--attach] [--thread] [-s | --signoff] [--start-number <n>]
14 [--in-reply-to=Message-Id] [--suffix=.<sfx>]
15 [--ignore-if-in-upstream]
21 Prepare each commit between <since> and <until> with its patch in
22 one file per commit, formatted to resemble UNIX mailbox format.
23 If ..<until> is not specified, the head of the current working
24 tree is implied. For a more complete list of ways to spell
25 <since> and <until>, see "SPECIFYING REVISIONS" section in
26 gitlink:git-rev-parse[1].
28 The output of this command is convenient for e-mail submission or
29 for use with gitlink:git-am[1].
31 Each output file is numbered sequentially from 1, and uses the
32 first line of the commit message (massaged for pathname safety) as
33 the filename. The names of the output files are printed to standard
34 output, unless the --stdout option is specified.
36 If -o is specified, output files are created in <dir>. Otherwise
37 they are created in the current working directory.
39 If -n is specified, instead of "[PATCH] Subject", the first line
40 is formatted as "[PATCH n/m] Subject".
42 If given --thread, git-format-patch will generate In-Reply-To and
43 References headers to make the second and subsequent patch mails appear
44 as replies to the first mail; this also generates a Message-Id header to
49 include::diff-options.txt[]
51 -o|--output-directory <dir>::
52 Use <dir> to store the resulting files, instead of the
53 current working directory.
56 Name output in '[PATCH n/m]' format.
59 Start numbering the patches at <n> instead of 1.
62 Do not strip/add '[PATCH]' from the first line of the
66 Add `Signed-off-by:` line to the commit message, using
67 the committer identity of yourself.
70 Print all commits to the standard output in mbox format,
71 instead of creating a file for each one.
74 Create attachments instead of inlining patches.
77 Add In-Reply-To and References headers to make the second and
78 subsequent mails appear as replies to the first. Also generates
79 the Message-Id header to reference.
81 --in-reply-to=Message-Id::
82 Make the first mail (or all the mails with --no-thread) appear as a
83 reply to the given Message-Id, which avoids breaking threads to
84 provide a new patch series.
86 --ignore-if-in-upstream::
87 Do not include a patch that matches a commit in
88 <until>..<since>. This will examine all patches reachable
89 from <since> but not from <until> and compare them with the
90 patches being generated, and any patch that matches is
94 Instead of using `.patch` as the suffix for generated
95 filenames, use specifed suffix. A common alternative is
98 Note that you would need to include the leading dot `.` if you
99 want a filename like `0001-description-of-my-change.patch`, and
100 the first letter does not have to be a dot. Leaving it empty would
105 You can specify extra mail header lines to be added to each
106 message in the repository configuration. Also you can specify
107 the default suffix different from the built-in one:
111 headers = "Organization: git-foo\n"
119 git-format-patch -k --stdout R1..R2 | git-am -3 -k::
120 Extract commits between revisions R1 and R2, and apply
121 them on top of the current branch using `git-am` to
124 git-format-patch origin::
125 Extract all commits which are in the current branch but
126 not in the origin branch. For each commit a separate file
127 is created in the current directory.
129 git-format-patch -M -B origin::
130 The same as the previous one. Additionally, it detects
131 and handles renames and complete rewrites intelligently to
132 produce a renaming patch. A renaming patch reduces the
133 amount of text output, and generally makes it easier to
134 review it. Note that the "patch" program does not
135 understand renaming patches, so use it only when you know
136 the recipient uses git to apply your patch.
138 git-format-patch -3::
139 Extract three topmost commits from the current branch
140 and format them as e-mailable patches.
