6 git-format-patch - Prepare patches for e-mail submission
12 'git-format-patch' [-n | -k] [-o <dir> | --stdout] [--attach] [--thread]
13 [-s | --signoff] [--diff-options] [--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 -o|--output-directory <dir>::
50 Use <dir> to store the resulting files, instead of the
51 current working directory.
54 Name output in '[PATCH n/m]' format.
57 Start numbering the patches at <n> instead of 1.
60 Do not strip/add '[PATCH]' from the first line of the
64 Add `Signed-off-by:` line to the commit message, using
65 the committer identity of yourself.
68 Print all commits to the standard output in mbox format,
69 instead of creating a file for each one.
72 Create attachments instead of inlining patches.
75 Add In-Reply-To and References headers to make the second and
76 subsequent mails appear as replies to the first. Also generates
77 the Message-Id header to reference.
79 --in-reply-to=Message-Id::
80 Make the first mail (or all the mails with --no-thread) appear as a
81 reply to the given Message-Id, which avoids breaking threads to
82 provide a new patch series.
84 --ignore-if-in-upstream::
85 Do not include a patch that matches a commit in
86 <until>..<since>. This will examine all patches reachable
87 from <since> but not from <until> and compare them with the
88 patches being generated, and any patch that matches is
92 Instead of using `.patch` as the suffix for generated
93 filenames, use specifed suffix. A common alternative is
96 Note that you would need to include the leading dot `.` if you
97 want a filename like `0001-description-of-my-change.patch`, and
98 the first letter does not have to be a dot. Leaving it empty would
103 You can specify extra mail header lines to be added to each
104 message in the repository configuration. Also you can specify
105 the default suffix different from the built-in one:
109 headers = "Organization: git-foo\n"
117 git-format-patch -k --stdout R1..R2 | git-am -3 -k::
118 Extract commits between revisions R1 and R2, and apply
119 them on top of the current branch using `git-am` to
122 git-format-patch origin::
123 Extract all commits which are in the current branch but
124 not in the origin branch. For each commit a separate file
125 is created in the current directory.
127 git-format-patch -M -B origin::
128 The same as the previous one. Additionally, it detects
129 and handles renames and complete rewrites intelligently to
130 produce a renaming patch. A renaming patch reduces the
131 amount of text output, and generally makes it easier to
132 review it. Note that the "patch" program does not
133 understand renaming patches, so use it only when you know
134 the recipient uses git to apply your patch.
136 git-format-patch -3::
137 Extract three topmost commits from the current branch
138 and format them as e-mailable patches.
