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]
19 [ <since> | <revision range> ]
24 Prepare each commit with its patch in
25 one file per commit, formatted to resemble UNIX mailbox format.
26 The output of this command is convenient for e-mail submission or
27 for use with gitlink:git-am[1].
29 There are two ways to specify which commits to operate on.
31 1. A single commit, <since>, specifies that the commits leading
32 to the tip of the current branch that are not in the history
33 that leads to the <since> to be output.
35 2. Generic <revision range> expression (see "SPECIFYING
36 REVISIONS" section in gitlink:git-rev-parse[1]) means the
37 commits in the specified range. A single commit, when
38 interpreted as a <revision range> expression, means
39 "everything that leads to that commit", but that is taken as
40 the special case above. If you want to format everything
41 since project inception to one commit, say "git format-patch
42 \--root <that-commit>", as showing the root commit as patch
43 requires \--root option anyway.
45 By default, each output file is numbered sequentially from 1, and uses the
46 first line of the commit message (massaged for pathname safety) as
47 the filename. With the --numbered-files option, the output file names
48 will only be numbers, without the first line of the commit appended.
49 The names of the output files are printed to standard
50 output, unless the --stdout option is specified.
52 If -o is specified, output files are created in <dir>. Otherwise
53 they are created in the current working directory.
55 If -n is specified, instead of "[PATCH] Subject", the first line
56 is formatted as "[PATCH n/m] Subject".
58 If given --thread, git-format-patch will generate In-Reply-To and
59 References headers to make the second and subsequent patch mails appear
60 as replies to the first mail; this also generates a Message-Id header to
65 include::diff-options.txt[]
68 Limits the number of patches to prepare.
70 -o|--output-directory <dir>::
71 Use <dir> to store the resulting files, instead of the
72 current working directory.
75 Name output in '[PATCH n/m]' format.
78 Start numbering the patches at <n> instead of 1.
81 Output file names will be a simple number sequence
82 without the default first line of the commit appended.
83 Mutually exclusive with the --stdout option.
86 Do not strip/add '[PATCH]' from the first line of the
90 Add `Signed-off-by:` line to the commit message, using
91 the committer identity of yourself.
94 Print all commits to the standard output in mbox format,
95 instead of creating a file for each one.
97 --attach[=<boundary>]::
98 Create multipart/mixed attachment, the first part of
99 which is the commit message and the patch itself in the
100 second part, with "Content-Disposition: attachment".
102 --inline[=<boundary>]::
103 Create multipart/mixed attachment, the first part of
104 which is the commit message and the patch itself in the
105 second part, with "Content-Disposition: inline".
108 Add In-Reply-To and References headers to make the second and
109 subsequent mails appear as replies to the first. Also generates
110 the Message-Id header to reference.
112 --in-reply-to=Message-Id::
113 Make the first mail (or all the mails with --no-thread) appear as a
114 reply to the given Message-Id, which avoids breaking threads to
115 provide a new patch series.
117 --ignore-if-in-upstream::
118 Do not include a patch that matches a commit in
119 <until>..<since>. This will examine all patches reachable
120 from <since> but not from <until> and compare them with the
121 patches being generated, and any patch that matches is
124 --subject-prefix=<Subject-Prefix>::
125 Instead of the standard '[PATCH]' prefix in the subject
126 line, instead use '[<Subject-Prefix>]'. This
127 allows for useful naming of a patch series, and can be
128 combined with the --numbered option.
131 Instead of using `.patch` as the suffix for generated
132 filenames, use specified suffix. A common alternative is
135 Note that you would need to include the leading dot `.` if you
136 want a filename like `0001-description-of-my-change.patch`, and
137 the first letter does not have to be a dot. Leaving it empty would
142 You can specify extra mail header lines to be added to each
143 message in the repository configuration. You can also specify
144 new defaults for the subject prefix and file suffix.
148 headers = "Organization: git-foo\n"
149 subjectprefix = CHANGE
157 git-format-patch -k --stdout R1..R2 | git-am -3 -k::
158 Extract commits between revisions R1 and R2, and apply
159 them on top of the current branch using `git-am` to
162 git-format-patch origin::
163 Extract all commits which are in the current branch but
164 not in the origin branch. For each commit a separate file
165 is created in the current directory.
167 git-format-patch \--root origin::
168 Extract all commits which that leads to 'origin' since the
169 inception of the project.
171 git-format-patch -M -B origin::
172 The same as the previous one. Additionally, it detects
173 and handles renames and complete rewrites intelligently to
174 produce a renaming patch. A renaming patch reduces the
175 amount of text output, and generally makes it easier to
176 review it. Note that the "patch" program does not
177 understand renaming patches, so use it only when you know
178 the recipient uses git to apply your patch.
180 git-format-patch -3::
181 Extract three topmost commits from the current branch
182 and format them as e-mailable patches.
