SYNOPSIS

-'git-format-patch' [-n][-o <dir>|--stdout][-k][--mbox][--diff-options] <his> [<mine>]
+[verse]
+'git-format-patch' [-n | -k] [-o <dir> | --stdout] [--thread]
+ [--attach[=<boundary>] | --inline[=<boundary>]]
+ [-s | --signoff] [<common diff options>] [--start-number <n>]

+ [--ignore-if-in-upstream]
+ [--subject-prefix=Subject-Prefix]
+ <since>[..<until>]
DESCRIPTION
-----------
-Prepare each commit with its patch since <mine> head forked from
-<his> head, one file per patch, for e-mail submission. Each
-output file is numbered sequentially from 1, and uses the first
-line of the commit message (massaged for pathname safety) as the
-filename.
-When -o is specified, output files are created in that
-directory; otherwise in the current working directory.
+Prepare each commit between <since> and <until> with its patch in
+one file per commit, formatted to resemble UNIX mailbox format.
+If ..<until> is not specified, the head of the current working
+tree is implied. For a more complete list of ways to spell
+<since> and <until>, see "SPECIFYING REVISIONS" section in
+gitlink:git-rev-parse[1].
-When -n is specified, instead of "[PATCH] Subject", the first
-line is formatted as "[PATCH N/M] Subject", unless you have only
-one patch.
+The output of this command is convenient for e-mail submission or
+for use with gitlink:git-am[1].
-When --mbox is specified, the output is formatted to resemble
-UNIX mailbox format, and can be concatenated together for
-processing with applymbox.
+Each output file is numbered sequentially from 1, and uses the
+first line of the commit message (massaged for pathname safety) as
+the filename. The names of the output files are printed to standard
+output, unless the --stdout option is specified.
+If -o is specified, output files are created in <dir>. Otherwise
+they are created in the current working directory.
+
+If -n is specified, instead of "[PATCH] Subject", the first line
+is formatted as "[PATCH n/m] Subject".
+
+If given --thread, git-format-patch will generate In-Reply-To and
+References headers to make the second and subsequent patch mails appear
+as replies to the first mail; this also generates a Message-Id header to
+reference.
OPTIONS
-------
--o <dir>::
+include::diff-options.txt[]
+
+-o|--output-directory <dir>::
Use <dir> to store the resulting files, instead of the
current working directory.
--n::
+-n|--numbered::
Name output in '[PATCH n/m]' format.
--k::
+--start-number <n>::
+ Start numbering the patches at <n> instead of 1.
+
+-k|--keep-subject::
Do not strip/add '[PATCH]' from the first line of the
commit log message.
---author, --date::
- Output From: and Date: headers for commits made by
- yourself as well. Usually these are output only for
- commits made by people other than yourself.
-
---mbox::
- Format the output files for closer to mbox format by
- adding a phony Unix "From " line, so they can be
- concatenated together and fed to `git-applymbox`.
- Implies --author and --date.
+-s|--signoff::
+ Add `Signed-off-by:` line to the commit message, using
+ the committer identity of yourself.
--stdout::
- This flag generates the mbox formatted output to the
- standard output, instead of saving them into a file per
- patch and implies --mbox.
+ Print all commits to the standard output in mbox format,
+ instead of creating a file for each one.
+
+--attach[=<boundary>]::
+ Create multipart/mixed attachment, the first part of
+ which is the commit message and the patch itself in the
+ second part, with "Content-Disposition: attachment".
+
+--inline[=<boundary>]::
+ Create multipart/mixed attachment, the first part of
+ which is the commit message and the patch itself in the
+ second part, with "Content-Disposition: inline".
+
+--thread::
+ Add In-Reply-To and References headers to make the second and
+ subsequent mails appear as replies to the first. Also generates
+ the Message-Id header to reference.
+
+--in-reply-to=Message-Id::
+ Make the first mail (or all the mails with --no-thread) appear as a
+ reply to the given Message-Id, which avoids breaking threads to
+ provide a new patch series.
+
+--ignore-if-in-upstream::
+ Do not include a patch that matches a commit in
+ <until>..<since>. This will examine all patches reachable
+ from <since> but not from <until> and compare them with the
+ patches being generated, and any patch that matches is
+ ignored.
+
+--subject-prefix=<Subject-Prefix>::
+ Instead of the standard '[PATCH]' prefix in the subject
+ line, instead use '[<Subject-Prefix>]'. This
+ allows for useful naming of a patch series, and can be
+ combined with the --numbered option.
+
+--suffix=.<sfx>::
+ Instead of using `.patch` as the suffix for generated
+ filenames, use specifed suffix. A common alternative is
+ `--suffix=.txt`.
++
+Note that you would need to include the leading dot `.` if you
+want a filename like `0001-description-of-my-change.patch`, and
+the first letter does not have to be a dot. Leaving it empty would
+not add any suffix.
+
+CONFIGURATION
+-------------
+You can specify extra mail header lines to be added to each
+message in the repository configuration. Also you can specify
+the default suffix different from the built-in one:
+
+------------
+[format]
+ headers = "Organization: git-foo\n"
+ suffix = .txt
+------------
EXAMPLES
cherry-pick them.
git-format-patch origin::
- Extract commits the current branch accumulated since it
- pulled from origin the last time in a patch form for
- e-mail submission.
-
+ Extract all commits which are in the current branch but
+ not in the origin branch. For each commit a separate file
+ is created in the current directory.
+
+git-format-patch -M -B origin::
+ The same as the previous one. Additionally, it detects
+ and handles renames and complete rewrites intelligently to
+ produce a renaming patch. A renaming patch reduces the
+ amount of text output, and generally makes it easier to
+ review it. Note that the "patch" program does not
+ understand renaming patches, so use it only when you know
+ the recipient uses git to apply your patch.
+
+git-format-patch -3::
+ Extract three topmost commits from the current branch
+ and format them as e-mailable patches.
