git-commit(1) ============= NAME ---- git-commit - Record changes to the repository SYNOPSIS -------- [verse] 'git commit' [-a | --interactive | --patch] [-s] [-v] [-u<mode>] [--amend] [--dry-run] [(-c | -C | --fixup | --squash) <commit>] [-F <file> | -m <msg>] [--reset-author] [--allow-empty] [--allow-empty-message] [--no-verify] [-e] [--author=<author>] [--date=<date>] [--cleanup=<mode>] [--[no-]status] [-i | -o] [-S[<keyid>]] [--] [<file>...] DESCRIPTION ----------- Stores the current contents of the index in a new commit along with a log message from the user describing the changes. The content to be added can be specified in several ways: 1. by using 'git add' to incrementally "add" changes to the index before using the 'commit' command (Note: even modified files must be "added"); 2. by using 'git rm' to remove files from the working tree and the index, again before using the 'commit' command; 3. by listing files as arguments to the 'commit' command, in which case the commit will ignore changes staged in the index, and instead record the current content of the listed files (which must already be known to Git); 4. by using the -a switch with the 'commit' command to automatically "add" changes from all known files (i.e. all files that are already listed in the index) and to automatically "rm" files in the index that have been removed from the working tree, and then perform the actual commit; 5. by using the --interactive or --patch switches with the 'commit' command to decide one by one which files or hunks should be part of the commit, before finalizing the operation. See the ``Interactive Mode'' section of linkgit:git-add[1] to learn how to operate these modes. The `--dry-run` option can be used to obtain a summary of what is included by any of the above for the next commit by giving the same set of parameters (options and paths). If you make a commit and then find a mistake immediately after that, you can recover from it with 'git reset'. OPTIONS ------- -a:: --all:: Tell the command to automatically stage files that have been modified and deleted, but new files you have not told Git about are not affected. -p:: --patch:: Use the interactive patch selection interface to chose which changes to commit. See linkgit:git-add[1] for details. -C <commit>:: --reuse-message=<commit>:: Take an existing commit object, and reuse the log message and the authorship information (including the timestamp) when creating the commit. -c <commit>:: --reedit-message=<commit>:: Like '-C', but with '-c' the editor is invoked, so that the user can further edit the commit message. --fixup=<commit>:: Construct a commit message for use with `rebase --autosquash`. The commit message will be the subject line from the specified commit with a prefix of "fixup! ". See linkgit:git-rebase[1] for details. --squash=<commit>:: Construct a commit message for use with `rebase --autosquash`. The commit message subject line is taken from the specified commit with a prefix of "squash! ". Can be used with additional commit message options (`-m`/`-c`/`-C`/`-F`). See linkgit:git-rebase[1] for details. --reset-author:: When used with -C/-c/--amend options, or when committing after a a conflicting cherry-pick, declare that the authorship of the resulting commit now belongs of the committer. This also renews the author timestamp. --short:: When doing a dry-run, give the output in the short-format. See linkgit:git-status[1] for details. Implies `--dry-run`. --branch:: Show the branch and tracking info even in short-format. --porcelain:: When doing a dry-run, give the output in a porcelain-ready format. See linkgit:git-status[1] for details. Implies `--dry-run`. --long:: When doing a dry-run, give the output in a the long-format. Implies `--dry-run`. -z:: --null:: When showing `short` or `porcelain` status output, terminate entries in the status output with NUL, instead of LF. If no format is given, implies the `--porcelain` output format. -F <file>:: --file=<file>:: Take the commit message from the given file. Use '-' to read the message from the standard input. --author=<author>:: Override the commit author. Specify an explicit author using the standard `A U Thor <author@example.com>` format. Otherwise <author> is assumed to be a pattern and is used to search for an existing commit by that author (i.e. rev-list --all -i --author=<author>); the commit author is then copied from the first such commit found. --date=<date>:: Override the author date used in the commit. -m <msg>:: --message=<msg>:: Use the given <msg> as the commit message. If multiple `-m` options are given, their values are concatenated as separate paragraphs. -t <file>:: --template=<file>:: When editing the commit message, start the editor with the contents in the given file. The `commit.template` configuration variable is often used to give this option implicitly to the command. This mechanism can be used by projects that want to guide participants with some hints on what to write in the message in what order. If the user exits the editor without editing the message, the commit is aborted. This has no effect when a message is given by other means, e.g. with the `-m` or `-F` options. -s:: --signoff:: Add Signed-off-by line by the committer at the end of the commit log message. -n:: --no-verify:: This option bypasses the pre-commit and commit-msg hooks. See also linkgit:githooks[5]. --allow-empty:: Usually recording a commit that has the exact same tree as its sole parent commit is a mistake, and the command prevents you from making such a commit. This option bypasses the safety, and is primarily for use by foreign SCM interface scripts. --allow-empty-message:: Like --allow-empty this command is primarily for use by foreign SCM interface scripts. It allows you to create a commit with an empty commit message without using plumbing commands like linkgit:git-commit-tree[1]. --cleanup=<mode>:: This option determines how the supplied commit message should be cleaned up before committing. The '<mode>' can be `strip`, `whitespace`, `verbatim`, or `default`. + -- strip:: Strip leading and trailing empty lines, trailing whitespace, and #commentary and collapse consecutive empty lines. whitespace:: Same as `strip` except #commentary is not removed. verbatim:: Do not change the message at all. default:: Same as `strip` if the message is to be edited. Otherwise `whitespace`. -- + The default can be changed by the 'commit.cleanup' configuration variable (see linkgit:git-config[1]). -e:: --edit:: The message taken from file with `-F`, command line with `-m`, and from commit object with `-C` are usually used as the commit log message unmodified. This option lets you further edit the message taken from these sources. --no-edit:: Use the selected commit message without launching an editor. For example, `git commit --amend --no-edit` amends a commit without changing its commit message. --amend:: Replace the tip of the current branch by creating a new commit. The recorded tree is prepared as usual (including the effect of the `-i` and `-o` options and explicit pathspec), and the message from the original commit is used as the starting point, instead of an empty message, when no other message is specified from the command line via options such as `-m`, `-F`, `-c`, etc. The new commit has the same parents and author as the current one (the `--reset-author` option can countermand this). + -- It is a rough equivalent for: ------ $ git reset --soft HEAD^ $ ... do something else to come up with the right tree ... $ git commit -c ORIG_HEAD ------ but can be used to amend a merge commit. -- + You should understand the implications of rewriting history if you amend a commit that has already been published. (See the "RECOVERING FROM UPSTREAM REBASE" section in linkgit:git-rebase[1].) --no-post-rewrite:: Bypass the post-rewrite hook. -i:: --include:: Before making a commit out of staged contents so far, stage the contents of paths given on the command line as well. This is usually not what you want unless you are concluding a conflicted merge. -o:: --only:: Make a commit only from the paths specified on the command line, disregarding any contents that have been staged so far. This is the default mode of operation of 'git commit' if any paths are given on the command line, in which case this option can be omitted. If this option is specified together with '--amend', then no paths need to be specified, which can be used to amend the last commit without committing changes that have already been staged. -u[<mode>]:: --untracked-files[=<mode>]:: Show untracked files. + The mode parameter is optional (defaults to 'all'), and is used to specify the handling of untracked files; when -u is not used, the default is 'normal', i.e. show untracked files and directories. + The possible options are: + - 'no' - Show no untracked files - 'normal' - Shows untracked files and directories - 'all' - Also shows individual files in untracked directories. + The default can be changed using the status.showUntrackedFiles configuration variable documented in linkgit:git-config[1]. -v:: --verbose:: Show unified diff between the HEAD commit and what would be committed at the bottom of the commit message template. Note that this diff output doesn't have its lines prefixed with '#'. -q:: --quiet:: Suppress commit summary message. --dry-run:: Do not create a commit, but show a list of paths that are to be committed, paths with local changes that will be left uncommitted and paths that are untracked. --status:: Include the output of linkgit:git-status[1] in the commit message template when using an editor to prepare the commit message. Defaults to on, but can be used to override configuration variable commit.status. --no-status:: Do not include the output of linkgit:git-status[1] in the commit message template when using an editor to prepare the default commit message. -S[<keyid>]:: --gpg-sign[=<keyid>]:: GPG-sign commit. \--:: Do not interpret any more arguments as options. <file>...:: When files are given on the command line, the command commits the contents of the named files, without recording the changes already staged. The contents of these files are also staged for the next commit on top of what have been staged before. :git-commit: 1 include::date-formats.txt[] EXAMPLES -------- When recording your own work, the contents of modified files in your working tree are temporarily stored to a staging area called the "index" with 'git add'. A file can be reverted back, only in the index but not in the working tree, to that of the last commit with `git reset HEAD -- <file>`, which effectively reverts 'git add' and prevents the changes to this file from participating in the next commit. After building the state to be committed incrementally with these commands, `git commit` (without any pathname parameter) is used to record what has been staged so far. This is the most basic form of the command. An example: ------------ $ edit hello.c $ git rm goodbye.c $ git add hello.c $ git commit ------------ Instead of staging files after each individual change, you can tell `git commit` to notice the changes to the files whose contents are tracked in your working tree and do corresponding `git add` and `git rm` for you. That is, this example does the same as the earlier example if there is no other change in your working tree: ------------ $ edit hello.c $ rm goodbye.c $ git commit -a ------------ The command `git commit -a` first looks at your working tree, notices that you have modified hello.c and removed goodbye.c, and performs necessary `git add` and `git rm` for you. After staging changes to many files, you can alter the order the changes are recorded in, by giving pathnames to `git commit`. When pathnames are given, the command makes a commit that only records the changes made to the named paths: ------------ $ edit hello.c hello.h $ git add hello.c hello.h $ edit Makefile $ git commit Makefile ------------ This makes a commit that records the modification to `Makefile`. The changes staged for `hello.c` and `hello.h` are not included in the resulting commit. However, their changes are not lost -- they are still staged and merely held back. After the above sequence, if you do: ------------ $ git commit ------------ this second commit would record the changes to `hello.c` and `hello.h` as expected. After a merge (initiated by 'git merge' or 'git pull') stops because of conflicts, cleanly merged paths are already staged to be committed for you, and paths that conflicted are left in unmerged state. You would have to first check which paths are conflicting with 'git status' and after fixing them manually in your working tree, you would stage the result as usual with 'git add': ------------ $ git status | grep unmerged unmerged: hello.c $ edit hello.c $ git add hello.c ------------ After resolving conflicts and staging the result, `git ls-files -u` would stop mentioning the conflicted path. When you are done, run `git commit` to finally record the merge: ------------ $ git commit ------------ As with the case to record your own changes, you can use `-a` option to save typing. One difference is that during a merge resolution, you cannot use `git commit` with pathnames to alter the order the changes are committed, because the merge should be recorded as a single commit. In fact, the command refuses to run when given pathnames (but see `-i` option). DISCUSSION ---------- Though not required, it's a good idea to begin the commit message with a single short (less than 50 character) line summarizing the change, followed by a blank line and then a more thorough description. The text up to the first blank line in a commit message is treated as the commit title, and that title is used throughout Git. For example, linkgit:git-format-patch[1] turns a commit into email, and it uses the title on the Subject line and the rest of the commit in the body. include::i18n.txt[] ENVIRONMENT AND CONFIGURATION VARIABLES --------------------------------------- The editor used to edit the commit log message will be chosen from the GIT_EDITOR environment variable, the core.editor configuration variable, the VISUAL environment variable, or the EDITOR environment variable (in that order). See linkgit:git-var[1] for details. HOOKS ----- This command can run `commit-msg`, `prepare-commit-msg`, `pre-commit`, and `post-commit` hooks. See linkgit:githooks[5] for more information. FILES ----- `$GIT_DIR/COMMIT_EDITMSG`:: This file contains the commit message of a commit in progress. If `git commit` exits due to an error before creating a commit, any commit message that has been provided by the user (e.g., in an editor session) will be available in this file, but will be overwritten by the next invocation of `git commit`.
