  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--porcelain::
 105        When doing a dry-run, give the output in a porcelain-ready
 106        format. See linkgit:git-status[1] for details. Implies
 107        `--dry-run`.
 108
 109-z::
 110        When showing `short` or `porcelain` status output, terminate
 111        entries in the status output with NUL, instead of LF. If no
 112        format is given, implies the `--porcelain` output format.
 113
 114-F <file>::
 115--file=<file>::
 116        Take the commit message from the given file.  Use '-' to
 117        read the message from the standard input.
 118
 119--author=<author>::
 120        Override the commit author. Specify an explicit author using the
 121        standard `A U Thor <author@example.com>` format. Otherwise <author>
 122        is assumed to be a pattern and is used to search for an existing
 123        commit by that author (i.e. rev-list --all -i --author=<author>);
 124        the commit author is then copied from the first such commit found.
 125
 126--date=<date>::
 127        Override the author date used in the commit.
 128
 129-m <msg>::
 130--message=<msg>::
 131        Use the given <msg> as the commit message.
 132
 133-t <file>::
 134--template=<file>::
 135        Use the contents of the given file as the initial version
 136        of the commit message. The editor is invoked and you can
 137        make subsequent changes. If a message is specified using
 138        the `-m` or `-F` options, this option has no effect. This
 139        overrides the `commit.template` configuration variable.
 140
 141-s::
 142--signoff::
 143        Add Signed-off-by line by the committer at the end of the commit
 144        log message.
 145
 146-n::
 147--no-verify::
 148        This option bypasses the pre-commit and commit-msg hooks.
 149        See also linkgit:githooks[5].
 150
 151--allow-empty::
 152        Usually recording a commit that has the exact same tree as its
 153        sole parent commit is a mistake, and the command prevents you
 154        from making such a commit.  This option bypasses the safety, and
 155        is primarily for use by foreign SCM interface scripts.
 156
 157--allow-empty-message::
 158       Like --allow-empty this command is primarily for use by foreign
 159       SCM interface scripts. It allows you to create a commit with an
 160       empty commit message without using plumbing commands like
 161       linkgit:git-commit-tree[1].
 162
 163--cleanup=<mode>::
 164        This option sets how the commit message is cleaned up.
 165        The  '<mode>' can be one of 'verbatim', 'whitespace', 'strip',
 166        and 'default'. The 'default' mode will strip leading and
 167        trailing empty lines and #commentary from the commit message
 168        only if the message is to be edited. Otherwise only whitespace
 169        removed. The 'verbatim' mode does not change message at all,
 170        'whitespace' removes just leading/trailing whitespace lines
 171        and 'strip' removes both whitespace and commentary.
 172
 173-e::
 174--edit::
 175        The message taken from file with `-F`, command line with
 176        `-m`, and from file with `-C` are usually used as the
 177        commit log message unmodified.  This option lets you
 178        further edit the message taken from these sources.
 179
 180--amend::
 181        Used to amend the tip of the current branch. Prepare the tree
 182        object you would want to replace the latest commit as usual
 183        (this includes the usual -i/-o and explicit paths), and the
 184        commit log editor is seeded with the commit message from the
 185        tip of the current branch. The commit you create replaces the
 186        current tip -- if it was a merge, it will have the parents of
 187        the current tip as parents -- so the current top commit is
 188        discarded.
 189+
 190--
 191It is a rough equivalent for:
 192------
 193        $ git reset --soft HEAD^
 194        $ ... do something else to come up with the right tree ...
 195        $ git commit -c ORIG_HEAD
 196
 197------
 198but can be used to amend a merge commit.
 199--
 200+
 201You should understand the implications of rewriting history if you
 202amend a commit that has already been published.  (See the "RECOVERING
 203FROM UPSTREAM REBASE" section in linkgit:git-rebase[1].)
 204
 205-i::
 206--include::
 207        Before making a commit out of staged contents so far,
 208        stage the contents of paths given on the command line
 209        as well.  This is usually not what you want unless you
 210        are concluding a conflicted merge.
 211
 212-o::
 213--only::
 214        Make a commit only from the paths specified on the
 215        command line, disregarding any contents that have been
 216        staged so far. This is the default mode of operation of
 217        'git commit' if any paths are given on the command line,
 218        in which case this option can be omitted.
 219        If this option is specified together with '--amend', then
 220        no paths need to be specified, which can be used to amend
 221        the last commit without committing changes that have
 222        already been staged.
 223
 224-u[<mode>]::
 225--untracked-files[=<mode>]::
 226        Show untracked files.
 227+
 228The mode parameter is optional (defaults to 'all'), and is used to
 229specify the handling of untracked files; when -u is not used, the
 230default is 'normal', i.e. show untracked files and directories.
 231+
 232The possible options are:
 233+
 234        - 'no'     - Show no untracked files
 235        - 'normal' - Shows untracked files and directories
 236        - 'all'    - Also shows individual files in untracked directories.
 237+
 238The default can be changed using the status.showUntrackedFiles
 239configuration variable documented in linkgit:git-config[1].
 240
 241-v::
 242--verbose::
 243        Show unified diff between the HEAD commit and what
 244        would be committed at the bottom of the commit message
 245        template.  Note that this diff output doesn't have its
 246        lines prefixed with '#'.
 247
 248-q::
 249--quiet::
 250        Suppress commit summary message.
 251
 252--dry-run::
 253        Do not create a commit, but show a list of paths that are
 254        to be committed, paths with local changes that will be left
 255        uncommitted and paths that are untracked.
 256
 257--status::
 258        Include the output of linkgit:git-status[1] in the commit
 259        message template when using an editor to prepare the commit
 260        message.  Defaults to on, but can be used to override
 261        configuration variable commit.status.
 262
 263--no-status::
 264        Do not include the output of linkgit:git-status[1] in the
 265        commit message template when using an editor to prepare the
 266        default commit message.
 267
 268\--::
 269        Do not interpret any more arguments as options.
 270
 271<file>...::
 272        When files are given on the command line, the command
 273        commits the contents of the named files, without
 274        recording the changes already staged.  The contents of
 275        these files are also staged for the next commit on top
 276        of what have been staged before.

 281EXAMPLES
 282--------
 283When recording your own work, the contents of modified files in
 284your working tree are temporarily stored to a staging area
 285called the "index" with 'git add'.  A file can be
 286reverted back, only in the index but not in the working tree,
 287to that of the last commit with `git reset HEAD \-- <file>`,
 288which effectively reverts 'git add' and prevents the changes to
 289this file from participating in the next commit.  After building
 290the state to be committed incrementally with these commands,
 291`git commit` (without any pathname parameter) is used to record what
 292has been staged so far.  This is the most basic form of the
 293command.  An example:
 294
 295------------
 296$ edit hello.c
 297$ git rm goodbye.c
 298$ git add hello.c
 299$ git commit
 300------------
 301
 302Instead of staging files after each individual change, you can
 303tell `git commit` to notice the changes to the files whose
 304contents are tracked in
 305your working tree and do corresponding `git add` and `git rm`
 306for you.  That is, this example does the same as the earlier
 307example if there is no other change in your working tree:
 308
 309------------
 310$ edit hello.c
 311$ rm goodbye.c
 312$ git commit -a
 313------------
 314
 315The command `git commit -a` first looks at your working tree,
 316notices that you have modified hello.c and removed goodbye.c,
 317and performs necessary `git add` and `git rm` for you.
 318
 319After staging changes to many files, you can alter the order the
 320changes are recorded in, by giving pathnames to `git commit`.
 321When pathnames are given, the command makes a commit that
 322only records the changes made to the named paths:
 323
 324------------
 325$ edit hello.c hello.h
 326$ git add hello.c hello.h
 327$ edit Makefile
 328$ git commit Makefile
 329------------
 330
 331This makes a commit that records the modification to `Makefile`.
 332The changes staged for `hello.c` and `hello.h` are not included
 333in the resulting commit.  However, their changes are not lost --
 334they are still staged and merely held back.  After the above
 335sequence, if you do:
 336
 337------------
 338$ git commit
 339------------
 340
 341this second commit would record the changes to `hello.c` and
 342`hello.h` as expected.
 343
 344After a merge (initiated by 'git merge' or 'git pull') stops
 345because of conflicts, cleanly merged
 346paths are already staged to be committed for you, and paths that
 347conflicted are left in unmerged state.  You would have to first
 348check which paths are conflicting with 'git status'
 349and after fixing them manually in your working tree, you would
 350stage the result as usual with 'git add':
 351
 352------------
 353$ git status | grep unmerged
 354unmerged: hello.c
 355$ edit hello.c
 356$ git add hello.c
 357------------
 358
 359After resolving conflicts and staging the result, `git ls-files -u`
 360would stop mentioning the conflicted path.  When you are done,
 361run `git commit` to finally record the merge:
 362
 363------------
 364$ git commit
 365------------
 366
 367As with the case to record your own changes, you can use `-a`
 368option to save typing.  One difference is that during a merge
 369resolution, you cannot use `git commit` with pathnames to
 370alter the order the changes are committed, because the merge
 371should be recorded as a single commit.  In fact, the command
 372refuses to run when given pathnames (but see `-i` option).
 373
 374
 375DISCUSSION
 376----------
 377
 378Though not required, it's a good idea to begin the commit message
 379with a single short (less than 50 character) line summarizing the
 380change, followed by a blank line and then a more thorough description.
 381Tools that turn commits into email, for example, use the first line
 382on the Subject: line and the rest of the commit in the body.
 383
 384include::i18n.txt[]
 385
 386ENVIRONMENT AND CONFIGURATION VARIABLES
 387---------------------------------------
 388The editor used to edit the commit log message will be chosen from the
 389GIT_EDITOR environment variable, the core.editor configuration variable, the
 390VISUAL environment variable, or the EDITOR environment variable (in that
 391order).  See linkgit:git-var[1] for details.
 392
 393HOOKS
 394-----
 395This command can run `commit-msg`, `prepare-commit-msg`, `pre-commit`,
 396and `post-commit` hooks.  See linkgit:githooks[5] for more
 397information.
