6 git-format-patch - Prepare patches for e-mail submission
12 'git-format-patch' [-k] [-o <dir> | --stdout] [--thread]
13 [--attach[=<boundary>] | --inline[=<boundary>]]
14 [-s | --signoff] [<common diff options>]
15 [-n | --numbered | -N | --no-numbered]
16 [--start-number <n>] [--numbered-files]
17 [--in-reply-to=Message-Id] [--suffix=.<sfx>]
18 [--ignore-if-in-upstream]
19 [--subject-prefix=Subject-Prefix]
21 [ <since> | <revision range> ]
26 Prepare each commit with its patch in
27 one file per commit, formatted to resemble UNIX mailbox format.
28 The output of this command is convenient for e-mail submission or
29 for use with linkgit:git-am[1].
31 There are two ways to specify which commits to operate on.
33 1. A single commit, <since>, specifies that the commits leading
34 to the tip of the current branch that are not in the history
35 that leads to the <since> to be output.
37 2. Generic <revision range> expression (see "SPECIFYING
38 REVISIONS" section in linkgit:git-rev-parse[1]) means the
39 commits in the specified range.
41 A single commit, when interpreted as a <revision range>
42 expression, means "everything that leads to that commit", but
43 if you write 'git format-patch <commit>', the previous rule
44 applies to that command line and you do not get "everything
45 since the beginning of the time". If you want to format
46 everything since project inception to one commit, say "git
47 format-patch \--root <commit>" to make it clear that it is the
50 By default, each output file is numbered sequentially from 1, and uses the
51 first line of the commit message (massaged for pathname safety) as
52 the filename. With the --numbered-files option, the output file names
53 will only be numbers, without the first line of the commit appended.
54 The names of the output files are printed to standard
55 output, unless the --stdout option is specified.
57 If -o is specified, output files are created in <dir>. Otherwise
58 they are created in the current working directory.
60 If -n is specified, instead of "[PATCH] Subject", the first line
61 is formatted as "[PATCH n/m] Subject".
63 If given --thread, git-format-patch will generate In-Reply-To and
64 References headers to make the second and subsequent patch mails appear
65 as replies to the first mail; this also generates a Message-Id header to
71 include::diff-options.txt[]
74 Limits the number of patches to prepare.
76 -o|--output-directory <dir>::
77 Use <dir> to store the resulting files, instead of the
78 current working directory.
81 Name output in '[PATCH n/m]' format.
84 Name output in '[PATCH]' format.
87 Start numbering the patches at <n> instead of 1.
90 Output file names will be a simple number sequence
91 without the default first line of the commit appended.
92 Mutually exclusive with the --stdout option.
95 Do not strip/add '[PATCH]' from the first line of the
99 Add `Signed-off-by:` line to the commit message, using
100 the committer identity of yourself.
103 Print all commits to the standard output in mbox format,
104 instead of creating a file for each one.
106 --attach[=<boundary>]::
107 Create multipart/mixed attachment, the first part of
108 which is the commit message and the patch itself in the
109 second part, with "Content-Disposition: attachment".
111 --inline[=<boundary>]::
112 Create multipart/mixed attachment, the first part of
113 which is the commit message and the patch itself in the
114 second part, with "Content-Disposition: inline".
117 Add In-Reply-To and References headers to make the second and
118 subsequent mails appear as replies to the first. Also generates
119 the Message-Id header to reference.
121 --in-reply-to=Message-Id::
122 Make the first mail (or all the mails with --no-thread) appear as a
123 reply to the given Message-Id, which avoids breaking threads to
124 provide a new patch series.
126 --ignore-if-in-upstream::
127 Do not include a patch that matches a commit in
128 <until>..<since>. This will examine all patches reachable
129 from <since> but not from <until> and compare them with the
130 patches being generated, and any patch that matches is
133 --subject-prefix=<Subject-Prefix>::
134 Instead of the standard '[PATCH]' prefix in the subject
135 line, instead use '[<Subject-Prefix>]'. This
136 allows for useful naming of a patch series, and can be
137 combined with the --numbered option.
140 Generate a cover letter template. You still have to fill in
141 a description, but the shortlog and the diffstat will be
145 Instead of using `.patch` as the suffix for generated
146 filenames, use specified suffix. A common alternative is
149 Note that you would need to include the leading dot `.` if you
150 want a filename like `0001-description-of-my-change.patch`, and
151 the first letter does not have to be a dot. Leaving it empty would
156 You can specify extra mail header lines to be added to each message
157 in the repository configuration, new defaults for the subject prefix
158 and file suffix, and number patches when outputting more than one.
162 headers = "Organization: git-foo\n"
163 subjectprefix = CHANGE
172 git-format-patch -k --stdout R1..R2 | git-am -3 -k::
173 Extract commits between revisions R1 and R2, and apply
174 them on top of the current branch using `git-am` to
177 git-format-patch origin::
178 Extract all commits which are in the current branch but
179 not in the origin branch. For each commit a separate file
180 is created in the current directory.
182 git-format-patch \--root origin::
183 Extract all commits that lead to 'origin' since the
184 inception of the project.
186 git-format-patch -M -B origin::
187 The same as the previous one. Additionally, it detects
188 and handles renames and complete rewrites intelligently to
189 produce a renaming patch. A renaming patch reduces the
190 amount of text output, and generally makes it easier to
191 review it. Note that the "patch" program does not
192 understand renaming patches, so use it only when you know
193 the recipient uses git to apply your patch.
195 git-format-patch -3::
196 Extract three topmost commits from the current branch
197 and format them as e-mailable patches.
