  18DESCRIPTION
  19-----------
  20Stores the current contents of the index in a new commit along
  21with a log message from the user describing the changes.
  22
  23The content to be added can be specified in several ways:
  24
  251. by using 'git add' to incrementally "add" changes to the
  26   index before using the 'commit' command (Note: even modified
  27   files must be "added");
  28
  292. by using 'git rm' to remove files from the working tree
  30   and the index, again before using the 'commit' command;
  31
  323. by listing files as arguments to the 'commit' command, in which
  33   case the commit will ignore changes staged in the index, and instead
  34   record the current content of the listed files (which must already
  35   be known to git);
  36
  374. by using the -a switch with the 'commit' command to automatically
  38   "add" changes from all known files (i.e. all files that are already
  39   listed in the index) and to automatically "rm" files in the index
  40   that have been removed from the working tree, and then perform the
  41   actual commit;
  42
  435. by using the --interactive or --patch switches with the 'commit' command
  44   to decide one by one which files or hunks should be part of the commit,
  45   before finalizing the operation. See the ``Interactive Mode'' section of
  46   linkgit:git-add[1] to learn how to operate these modes.
  47
  48The `--dry-run` option can be used to obtain a
  49summary of what is included by any of the above for the next
  50commit by giving the same set of parameters (options and paths).
  51
  52If you make a commit and then find a mistake immediately after
  53that, you can recover from it with 'git reset'.
  54
  55
  56OPTIONS
  57-------
  58-a::
  59--all::
  60        Tell the command to automatically stage files that have
  61        been modified and deleted, but new files you have not
  62        told git about are not affected.
  63
  64-p::
  65--patch::
  66        Use the interactive patch selection interface to chose
  67        which changes to commit. See linkgit:git-add[1] for
  68        details.
  69
  70-C <commit>::
  71--reuse-message=<commit>::
  72        Take an existing commit object, and reuse the log message
  73        and the authorship information (including the timestamp)
  74        when creating the commit.
  75
  76-c <commit>::
  77--reedit-message=<commit>::
  78        Like '-C', but with '-c' the editor is invoked, so that
  79        the user can further edit the commit message.
  80
  81--fixup=<commit>::
  82        Construct a commit message for use with `rebase --autosquash`.
  83        The commit message will be the subject line from the specified
  84        commit with a prefix of "fixup! ".  See linkgit:git-rebase[1]
  85        for details.
  86
  87--squash=<commit>::
  88        Construct a commit message for use with `rebase --autosquash`.
  89        The commit message subject line is taken from the specified
  90        commit with a prefix of "squash! ".  Can be used with additional
  91        commit message options (`-m`/`-c`/`-C`/`-F`). See
  92        linkgit:git-rebase[1] for details.
  93
  94--reset-author::
  95        When used with -C/-c/--amend options, or when committing after a
  96        a conflicting cherry-pick, declare that the authorship of the
  97        resulting commit now belongs of the committer. This also renews
  98        the author timestamp.
  99
 100--short::
 101        When doing a dry-run, give the output in the short-format. See
 102        linkgit:git-status[1] for details. Implies `--dry-run`.
 103
 104--branch::
 105        Show the branch and tracking info even in short-format.
 106
 107--porcelain::
 108        When doing a dry-run, give the output in a porcelain-ready
 109        format. See linkgit:git-status[1] for details. Implies
 110        `--dry-run`.
 111
 112-z::
 113--null::
 114        When showing `short` or `porcelain` status output, terminate
 115        entries in the status output with NUL, instead of LF. If no
 116        format is given, implies the `--porcelain` output format.
 117
 118-F <file>::
 119--file=<file>::
 120        Take the commit message from the given file.  Use '-' to
 121        read the message from the standard input.
 122
 123--author=<author>::
 124        Override the commit author. Specify an explicit author using the
 125        standard `A U Thor <author@example.com>` format. Otherwise <author>
 126        is assumed to be a pattern and is used to search for an existing
 127        commit by that author (i.e. rev-list --all -i --author=<author>);
 128        the commit author is then copied from the first such commit found.
 129
 130--date=<date>::
 131        Override the author date used in the commit.
 132
 133-m <msg>::
 134--message=<msg>::
 135        Use the given <msg> as the commit message.
 136
 137-t <file>::
 138--template=<file>::
 139        When editing the commit message, start the editor with the
 140        contents in the given file.  The `commit.template` configuration
 141        variable is often used to give this option implicitly to the
 142        command.  This mechanism can be used by projects that want to
 143        guide participants with some hints on what to write in the message
 144        in what order.  If the user exits the editor without editing the
 145        message, the commit is aborted.  This has no effect when a message
 146        is given by other means, e.g. with the `-m` or `-F` options.
 147
 148-s::
 149--signoff::
 150        Add Signed-off-by line by the committer at the end of the commit
 151        log message.
 152
 153-n::
 154--no-verify::
 155        This option bypasses the pre-commit and commit-msg hooks.
 156        See also linkgit:githooks[5].
 157
 158--allow-empty::
 159        Usually recording a commit that has the exact same tree as its
 160        sole parent commit is a mistake, and the command prevents you
 161        from making such a commit.  This option bypasses the safety, and
 162        is primarily for use by foreign SCM interface scripts.
 163
 164--allow-empty-message::
 165       Like --allow-empty this command is primarily for use by foreign
 166       SCM interface scripts. It allows you to create a commit with an
 167       empty commit message without using plumbing commands like
 168       linkgit:git-commit-tree[1].
 169
 170--cleanup=<mode>::
 171        This option sets how the commit message is cleaned up.
 172        The  '<mode>' can be one of 'verbatim', 'whitespace', 'strip',
 173        and 'default'. The 'default' mode will strip leading and
 174        trailing empty lines and #commentary from the commit message
 175        only if the message is to be edited. Otherwise only whitespace
 176        removed. The 'verbatim' mode does not change message at all,
 177        'whitespace' removes just leading/trailing whitespace lines
 178        and 'strip' removes both whitespace and commentary.
 179
 180-e::
 181--edit::
 182        The message taken from file with `-F`, command line with
 183        `-m`, and from file with `-C` are usually used as the
 184        commit log message unmodified.  This option lets you
 185        further edit the message taken from these sources.
 186
 187--no-edit::
 188        Use the selected commit message without launching an editor.
 189        For example, `git commit --amend --no-edit` amends a commit
 190        without changing its commit message.
 191
 192--amend::
 193        Used to amend the tip of the current branch. Prepare the tree
 194        object you would want to replace the latest commit as usual
 195        (this includes the usual -i/-o and explicit paths), and the
 196        commit log editor is seeded with the commit message from the
 197        tip of the current branch. The commit you create replaces the
 198        current tip -- if it was a merge, it will have the parents of
 199        the current tip as parents -- so the current top commit is
 200        discarded.
 201+
 202--
 203It is a rough equivalent for:
 204------
 205        $ git reset --soft HEAD^
 206        $ ... do something else to come up with the right tree ...
 207        $ git commit -c ORIG_HEAD
 208
 209------
 210but can be used to amend a merge commit.
 211--
 212+
 213You should understand the implications of rewriting history if you
 214amend a commit that has already been published.  (See the "RECOVERING
 215FROM UPSTREAM REBASE" section in linkgit:git-rebase[1].)
 216
 217--no-post-rewrite::
 218        Bypass the post-rewrite hook.
 219
 220-i::
 221--include::
 222        Before making a commit out of staged contents so far,
 223        stage the contents of paths given on the command line
 224        as well.  This is usually not what you want unless you
 225        are concluding a conflicted merge.
 226
 227-o::
 228--only::
 229        Make a commit only from the paths specified on the
 230        command line, disregarding any contents that have been
 231        staged so far. This is the default mode of operation of
 232        'git commit' if any paths are given on the command line,
 233        in which case this option can be omitted.
 234        If this option is specified together with '--amend', then
 235        no paths need to be specified, which can be used to amend
 236        the last commit without committing changes that have
 237        already been staged.
 238
 239-u[<mode>]::
 240--untracked-files[=<mode>]::
 241        Show untracked files.
 242+
 243The mode parameter is optional (defaults to 'all'), and is used to
 244specify the handling of untracked files; when -u is not used, the
 245default is 'normal', i.e. show untracked files and directories.
 246+
 247The possible options are:
 248+
 249        - 'no'     - Show no untracked files
 250        - 'normal' - Shows untracked files and directories
 251        - 'all'    - Also shows individual files in untracked directories.
 252+
 253The default can be changed using the status.showUntrackedFiles
 254configuration variable documented in linkgit:git-config[1].
 255
 256-v::
 257--verbose::
 258        Show unified diff between the HEAD commit and what
 259        would be committed at the bottom of the commit message
 260        template.  Note that this diff output doesn't have its
 261        lines prefixed with '#'.
 262
 263-q::
 264--quiet::
 265        Suppress commit summary message.
 266
 267--dry-run::
 268        Do not create a commit, but show a list of paths that are
 269        to be committed, paths with local changes that will be left
 270        uncommitted and paths that are untracked.
 271
 272--status::
 273        Include the output of linkgit:git-status[1] in the commit
 274        message template when using an editor to prepare the commit
 275        message.  Defaults to on, but can be used to override
 276        configuration variable commit.status.
 277
 278--no-status::
 279        Do not include the output of linkgit:git-status[1] in the
 280        commit message template when using an editor to prepare the
 281        default commit message.
 282
 283-S[<keyid>]::
 284--gpg-sign[=<keyid>]::
 285        GPG-sign commit.
 286
 287\--::
 288        Do not interpret any more arguments as options.
 289
 290<file>...::
 291        When files are given on the command line, the command
 292        commits the contents of the named files, without
 293        recording the changes already staged.  The contents of
 294        these files are also staged for the next commit on top
 295        of what have been staged before.

 300EXAMPLES
 301--------
 302When recording your own work, the contents of modified files in
 303your working tree are temporarily stored to a staging area
 304called the "index" with 'git add'.  A file can be
 305reverted back, only in the index but not in the working tree,
 306to that of the last commit with `git reset HEAD -- <file>`,
 307which effectively reverts 'git add' and prevents the changes to
 308this file from participating in the next commit.  After building
 309the state to be committed incrementally with these commands,
 310`git commit` (without any pathname parameter) is used to record what
 311has been staged so far.  This is the most basic form of the
 312command.  An example:
 313
 314------------
 315$ edit hello.c
 316$ git rm goodbye.c
 317$ git add hello.c
 318$ git commit
 319------------
 320
 321Instead of staging files after each individual change, you can
 322tell `git commit` to notice the changes to the files whose
 323contents are tracked in
 324your working tree and do corresponding `git add` and `git rm`
 325for you.  That is, this example does the same as the earlier
 326example if there is no other change in your working tree:
 327
 328------------
 329$ edit hello.c
 330$ rm goodbye.c
 331$ git commit -a
 332------------
 333
 334The command `git commit -a` first looks at your working tree,
 335notices that you have modified hello.c and removed goodbye.c,
 336and performs necessary `git add` and `git rm` for you.
 337
 338After staging changes to many files, you can alter the order the
 339changes are recorded in, by giving pathnames to `git commit`.
 340When pathnames are given, the command makes a commit that
 341only records the changes made to the named paths:
 342
 343------------
 344$ edit hello.c hello.h
 345$ git add hello.c hello.h
 346$ edit Makefile
 347$ git commit Makefile
 348------------
 349
 350This makes a commit that records the modification to `Makefile`.
 351The changes staged for `hello.c` and `hello.h` are not included
 352in the resulting commit.  However, their changes are not lost --
 353they are still staged and merely held back.  After the above
 354sequence, if you do:
 355
 356------------
 357$ git commit
 358------------
 359
 360this second commit would record the changes to `hello.c` and
 361`hello.h` as expected.
 362
 363After a merge (initiated by 'git merge' or 'git pull') stops
 364because of conflicts, cleanly merged
 365paths are already staged to be committed for you, and paths that
 366conflicted are left in unmerged state.  You would have to first
 367check which paths are conflicting with 'git status'
 368and after fixing them manually in your working tree, you would
 369stage the result as usual with 'git add':
 370
 371------------
 372$ git status | grep unmerged
 373unmerged: hello.c
 374$ edit hello.c
 375$ git add hello.c
 376------------
 377
 378After resolving conflicts and staging the result, `git ls-files -u`
 379would stop mentioning the conflicted path.  When you are done,
 380run `git commit` to finally record the merge:
 381
 382------------
 383$ git commit
 384------------
 385
 386As with the case to record your own changes, you can use `-a`
 387option to save typing.  One difference is that during a merge
 388resolution, you cannot use `git commit` with pathnames to
 389alter the order the changes are committed, because the merge
 390should be recorded as a single commit.  In fact, the command
 391refuses to run when given pathnames (but see `-i` option).
 392
 393
 394DISCUSSION
 395----------
 396
 397Though not required, it's a good idea to begin the commit message
 398with a single short (less than 50 character) line summarizing the
 399change, followed by a blank line and then a more thorough description.
 400The text up to the first blank line in a commit message is treated
 401as the commit title, and that title is used throughout git.
 402For example, linkgit:git-format-patch[1] turns a commit into email, and it uses
 403the title on the Subject line and the rest of the commit in the body.
 404
 405include::i18n.txt[]
 406
 407ENVIRONMENT AND CONFIGURATION VARIABLES
 408---------------------------------------
 409The editor used to edit the commit log message will be chosen from the
 410GIT_EDITOR environment variable, the core.editor configuration variable, the
 411VISUAL environment variable, or the EDITOR environment variable (in that
 412order).  See linkgit:git-var[1] for details.
 413
 414HOOKS
 415-----
 416This command can run `commit-msg`, `prepare-commit-msg`, `pre-commit`,
 417and `post-commit` hooks.  See linkgit:githooks[5] for more
 418information.
 419
 420FILES
 421-----
 422
 423`$GIT_DIR/COMMIT_EDITMSG`::
 424        This file contains the commit message of a commit in progress.
 425        If `git commit` exits due to an error before creating a commit,
 426        any commit message that has been provided by the user (e.g., in
 427        an editor session) will be available in this file, but will be
 428        overwritten by the next invocation of `git commit`.
