6 git-format-patch - Prepare patches for e-mail submission
12 'git-format-patch' [-n | -k] [-o <dir> | --stdout] [--thread]
13 [--attach[=<boundary>] | --inline[=<boundary>]]
14 [-s | --signoff] [<common diff options>]
15 [--start-number <n>] [--numbered-files]
16 [--in-reply-to=Message-Id] [--suffix=.<sfx>]
17 [--ignore-if-in-upstream]
18 [--subject-prefix=Subject-Prefix]
24 Prepare each commit between <since> and <until> with its patch in
25 one file per commit, formatted to resemble UNIX mailbox format.
26 If ..<until> is not specified, the head of the current working
27 tree is implied. For a more complete list of ways to spell
28 <since> and <until>, see "SPECIFYING REVISIONS" section in
29 gitlink:git-rev-parse[1].
31 The output of this command is convenient for e-mail submission or
32 for use with gitlink:git-am[1].
34 By default, each output file is numbered sequentially from 1, and uses the
35 first line of the commit message (massaged for pathname safety) as
36 the filename. With the --numbered-files option, the output file names
37 will only be numbers, without the first line of the commit appended.
38 The names of the output files are printed to standard
39 output, unless the --stdout option is specified.
41 If -o is specified, output files are created in <dir>. Otherwise
42 they are created in the current working directory.
44 If -n is specified, instead of "[PATCH] Subject", the first line
45 is formatted as "[PATCH n/m] Subject".
47 If given --thread, git-format-patch will generate In-Reply-To and
48 References headers to make the second and subsequent patch mails appear
49 as replies to the first mail; this also generates a Message-Id header to
54 include::diff-options.txt[]
57 Limits the number of patches to prepare.
59 -o|--output-directory <dir>::
60 Use <dir> to store the resulting files, instead of the
61 current working directory.
64 Name output in '[PATCH n/m]' format.
67 Start numbering the patches at <n> instead of 1.
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.
75 Do not strip/add '[PATCH]' from the first line of the
79 Add `Signed-off-by:` line to the commit message, using
80 the committer identity of yourself.
83 Print all commits to the standard output in mbox format,
84 instead of creating a file for each one.
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".
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".
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.
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.
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
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.
120 Instead of using `.patch` as the suffix for generated
121 filenames, use specifed suffix. A common alternative is
124 Note that you would need to include the leading dot `.` if you
125 want a filename like `0001-description-of-my-change.patch`, and
126 the first letter does not have to be a dot. Leaving it empty would
131 You can specify extra mail header lines to be added to each
132 message in the repository configuration. You can also specify
133 new defaults for the subject prefix and file suffix.
137 headers = "Organization: git-foo\n"
138 subjectprefix = CHANGE
146 git-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
151 git-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.
156 git-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.
165 git-format-patch -3::
166 Extract three topmost commits from the current branch
167 and format them as e-mailable patches.
