A single commit, <since>, specifies that the commits leading + to the tip of the current branch that are not in the history + that leads to the <since> to be output. + +2. Generic <revision range> expression (see "SPECIFYING + REVISIONS" section in linkgit:git-rev-parse[1]) means the + commits in the specified range. + +A single commit, when interpreted as a <revision range> +expression, means "everything that leads to that commit", but +if you write 'git format-patch <commit>', the previous rule +applies to that command line and you do not get "everything +since the beginning of the time". If you want to format +everything since project inception to one commit, say "git +format-patch \--root <commit>" to make it clear that it is the +latter case. + +By default, each output file is numbered sequentially from 1, and uses the +first line of the commit message (massaged for pathname safety) as +the filename. With the --numbered-files option, the output file names +will only be numbers, without the first line of the commit appended. +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 +------- +:git-format-patch: 1 +include::diff-options.txt[] + +-<n>:: + Limits the number of patches to prepare. + +-o|--output-directory <dir>:: + Use <dir> to store the resulting files, instead of the + current working directory. + +-n|--numbered:: + Name output in '[PATCH n/m]' format. + +-N|--no-numbered:: + Name output in '[PATCH]' format. + +--start-number <n>:: + Start numbering the patches at <n> instead of 1. + +--numbered-files:: + Output file names will be a simple number sequence + without the default first line of the commit appended. + Mutually exclusive with the --stdout option. + +-k|--keep-subject:: + Do not strip/add '[PATCH]' from the first line of the + commit log message. + +-s|--signoff:: + Add `Signed-off-by:` line to the commit message, using + the committer identity of yourself. + +--stdout:: + 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 specified 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, new defaults for the subject prefix +and file suffix, and number patches when outputting more than one. + +------------ +[format] + headers = "Organization: git-foo\n" + subjectprefix = CHANGE + suffix = .txt + numbered = auto +------------ + + +EXAMPLES +-------- + +git-format-patch -k --stdout R1..R2 | git-am -3 -k:: + Extract commits between revisions R1 and R2, and apply + them on top of the current branch using `git-am` to + cherry-pick them. + +git-format-patch origin:: + 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 \--root origin:: + Extract all commits that lead to 'origin' since the + inception of the project. + +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. + +See Also +-------- +linkgit:git-am[1], linkgit:git-send-email[1] + + +Author +------ +Written by Junio C Hamano <junkio@cox.net> + +Documentation +-------------- +Documentation by Junio C Hamano and the git-list <git@vger.kernel.org>. + +GIT +--- +Part of the linkgit:git[7] suite |
