  17DESCRIPTION
  18-----------
  19Stores the current contents of the index in a new commit along
  20with a log message from the user describing the changes.
  21
  22The content to be added can be specified in several ways:
  23
  241. by using 'git add' to incrementally "add" changes to the
  25   index before using the 'commit' command (Note: even modified
  26   files must be "added");
  27
  282. by using 'git rm' to remove files from the working tree
  29   and the index, again before using the 'commit' command;
  30
  313. by listing files as arguments to the 'commit' command, in which
  32   case the commit will ignore changes staged in the index, and instead
  33   record the current content of the listed files (which must already
  34   be known to git);
  35
  364. by using the -a switch with the 'commit' command to automatically
  37   "add" changes from all known files (i.e. all files that are already
  38   listed in the index) and to automatically "rm" files in the index
  39   that have been removed from the working tree, and then perform the
  40   actual commit;
  41
  425. by using the --interactive switch with the 'commit' command to decide one
  43   by one which files should be part of the commit, before finalizing the
  44   operation.  Currently, this is done by invoking 'git add --interactive'.
  45
  46The `--dry-run` option can be used to obtain a
  47summary of what is included by any of the above for the next
  48commit by giving the same set of parameters (options and paths).
  49
  50If you make a commit and then find a mistake immediately after
  51that, you can recover from it with 'git reset'.
  52
  53
  54OPTIONS
  55-------
  56-a::
  57--all::
  58        Tell the command to automatically stage files that have
  59        been modified and deleted, but new files you have not
  60        told git about are not affected.
  61
  62-C <commit>::
  63--reuse-message=<commit>::
  64        Take an existing commit object, and reuse the log message
  65        and the authorship information (including the timestamp)
  66        when creating the commit.
  67
  68-c <commit>::
  69--reedit-message=<commit>::
  70        Like '-C', but with '-c' the editor is invoked, so that
  71        the user can further edit the commit message.
  72
  73--fixup=<commit>::
  74        Construct a commit message for use with `rebase --autosquash`.
  75        The commit message will be the subject line from the specified
  76        commit with a prefix of "fixup! ".  See linkgit:git-rebase[1]
  77        for details.
  78
  79--reset-author::
  80        When used with -C/-c/--amend options, declare that the
  81        authorship of the resulting commit now belongs of the committer.
  82        This also renews the author timestamp.
  83
  84--short::
  85        When doing a dry-run, give the output in the short-format. See
  86        linkgit:git-status[1] for details. Implies `--dry-run`.
  87
  88--porcelain::
  89        When doing a dry-run, give the output in a porcelain-ready
  90        format. See linkgit:git-status[1] for details. Implies
  91        `--dry-run`.
  92
  93-z::
  94        When showing `short` or `porcelain` status output, terminate
  95        entries in the status output with NUL, instead of LF. If no
  96        format is given, implies the `--porcelain` output format.
  97
  98-F <file>::
  99--file=<file>::
 100        Take the commit message from the given file.  Use '-' to
 101        read the message from the standard input.
 102
 103--author=<author>::
 104        Override the commit author. Specify an explicit author using the
 105        standard `A U Thor <author@example.com>` format. Otherwise <author>
 106        is assumed to be a pattern and is used to search for an existing
 107        commit by that author (i.e. rev-list --all -i --author=<author>);
 108        the commit author is then copied from the first such commit found.
 109
 110--date=<date>::
 111        Override the author date used in the commit.
 112
 113-m <msg>::
 114--message=<msg>::
 115        Use the given <msg> as the commit message.
 116
 117-t <file>::
 118--template=<file>::
 119        Use the contents of the given file as the initial version
 120        of the commit message. The editor is invoked and you can
 121        make subsequent changes. If a message is specified using
 122        the `-m` or `-F` options, this option has no effect. This
 123        overrides the `commit.template` configuration variable.
 124
 125-s::
 126--signoff::
 127        Add Signed-off-by line by the committer at the end of the commit
 128        log message.
 129
 130-n::
 131--no-verify::
 132        This option bypasses the pre-commit and commit-msg hooks.
 133        See also linkgit:githooks[5].
 134
 135--allow-empty::
 136        Usually recording a commit that has the exact same tree as its
 137        sole parent commit is a mistake, and the command prevents you
 138        from making such a commit.  This option bypasses the safety, and
 139        is primarily for use by foreign SCM interface scripts.
 140
 141--allow-empty-message::
 142       Like --allow-empty this command is primarily for use by foreign
 143       SCM interface scripts. It allows you to create a commit with an
 144       empty commit message without using plumbing commands like
 145       linkgit:git-commit-tree[1].
 146
 147--cleanup=<mode>::
 148        This option sets how the commit message is cleaned up.
 149        The  '<mode>' can be one of 'verbatim', 'whitespace', 'strip',
 150        and 'default'. The 'default' mode will strip leading and
 151        trailing empty lines and #commentary from the commit message
 152        only if the message is to be edited. Otherwise only whitespace
 153        removed. The 'verbatim' mode does not change message at all,
 154        'whitespace' removes just leading/trailing whitespace lines
 155        and 'strip' removes both whitespace and commentary.
 156
 157-e::
 158--edit::
 159        The message taken from file with `-F`, command line with
 160        `-m`, and from file with `-C` are usually used as the
 161        commit log message unmodified.  This option lets you
 162        further edit the message taken from these sources.
 163
 164--amend::
 165        Used to amend the tip of the current branch. Prepare the tree
 166        object you would want to replace the latest commit as usual
 167        (this includes the usual -i/-o and explicit paths), and the
 168        commit log editor is seeded with the commit message from the
 169        tip of the current branch. The commit you create replaces the
 170        current tip -- if it was a merge, it will have the parents of
 171        the current tip as parents -- so the current top commit is
 172        discarded.
 173+
 174--
 175It is a rough equivalent for:
 176------
 177        $ git reset --soft HEAD^
 178        $ ... do something else to come up with the right tree ...
 179        $ git commit -c ORIG_HEAD
 180
 181------
 182but can be used to amend a merge commit.
 183--
 184+
 185You should understand the implications of rewriting history if you
 186amend a commit that has already been published.  (See the "RECOVERING
 187FROM UPSTREAM REBASE" section in linkgit:git-rebase[1].)
 188
 189-i::
 190--include::
 191        Before making a commit out of staged contents so far,
 192        stage the contents of paths given on the command line
 193        as well.  This is usually not what you want unless you
 194        are concluding a conflicted merge.
 195
 196-o::
 197--only::
 198        Make a commit only from the paths specified on the
 199        command line, disregarding any contents that have been
 200        staged so far. This is the default mode of operation of
 201        'git commit' if any paths are given on the command line,
 202        in which case this option can be omitted.
 203        If this option is specified together with '--amend', then
 204        no paths need to be specified, which can be used to amend
 205        the last commit without committing changes that have
 206        already been staged.
 207
 208-u[<mode>]::
 209--untracked-files[=<mode>]::
 210        Show untracked files (Default: 'all').
 211+
 212The mode parameter is optional, and is used to specify
 213the handling of untracked files.
 214+
 215The possible options are:
 216+
 217        - 'no'     - Show no untracked files
 218        - 'normal' - Shows untracked files and directories
 219        - 'all'    - Also shows individual files in untracked directories.
 220+
 221See linkgit:git-config[1] for configuration variable
 222used to change the default for when the option is not
 223specified.
 224
 225-v::
 226--verbose::
 227        Show unified diff between the HEAD commit and what
 228        would be committed at the bottom of the commit message
 229        template.  Note that this diff output doesn't have its
 230        lines prefixed with '#'.
 231
 232-q::
 233--quiet::
 234        Suppress commit summary message.
 235
 236--dry-run::
 237        Do not create a commit, but show a list of paths that are
 238        to be committed, paths with local changes that will be left
 239        uncommitted and paths that are untracked.
 240
 241--status::
 242        Include the output of linkgit:git-status[1] in the commit
 243        message template when using an editor to prepare the commit
 244        message.  Defaults to on, but can be used to override
 245        configuration variable commit.status.
 246
 247--no-status::
 248        Do not include the output of linkgit:git-status[1] in the
 249        commit message template when using an editor to prepare the
 250        default commit message.
 251
 252\--::
 253        Do not interpret any more arguments as options.
 254
 255<file>...::
 256        When files are given on the command line, the command
 257        commits the contents of the named files, without
 258        recording the changes already staged.  The contents of
 259        these files are also staged for the next commit on top
 260        of what have been staged before.

 265EXAMPLES
 266--------
 267When recording your own work, the contents of modified files in
 268your working tree are temporarily stored to a staging area
 269called the "index" with 'git add'.  A file can be
 270reverted back, only in the index but not in the working tree,
 271to that of the last commit with `git reset HEAD -- <file>`,
 272which effectively reverts 'git add' and prevents the changes to
 273this file from participating in the next commit.  After building
 274the state to be committed incrementally with these commands,
 275`git commit` (without any pathname parameter) is used to record what
 276has been staged so far.  This is the most basic form of the
 277command.  An example:
 278
 279------------
 280$ edit hello.c
 281$ git rm goodbye.c
 282$ git add hello.c
 283$ git commit
 284------------
 285
 286Instead of staging files after each individual change, you can
 287tell `git commit` to notice the changes to the files whose
 288contents are tracked in
 289your working tree and do corresponding `git add` and `git rm`
 290for you.  That is, this example does the same as the earlier
 291example if there is no other change in your working tree:
 292
 293------------
 294$ edit hello.c
 295$ rm goodbye.c
 296$ git commit -a
 297------------
 298
 299The command `git commit -a` first looks at your working tree,
 300notices that you have modified hello.c and removed goodbye.c,
 301and performs necessary `git add` and `git rm` for you.
 302
 303After staging changes to many files, you can alter the order the
 304changes are recorded in, by giving pathnames to `git commit`.
 305When pathnames are given, the command makes a commit that
 306only records the changes made to the named paths:
 307
 308------------
 309$ edit hello.c hello.h
 310$ git add hello.c hello.h
 311$ edit Makefile
 312$ git commit Makefile
 313------------
 314
 315This makes a commit that records the modification to `Makefile`.
 316The changes staged for `hello.c` and `hello.h` are not included
 317in the resulting commit.  However, their changes are not lost --
 318they are still staged and merely held back.  After the above
 319sequence, if you do:
 320
 321------------
 322$ git commit
 323------------
 324
 325this second commit would record the changes to `hello.c` and
 326`hello.h` as expected.
 327
 328After a merge (initiated by 'git merge' or 'git pull') stops
 329because of conflicts, cleanly merged
 330paths are already staged to be committed for you, and paths that
 331conflicted are left in unmerged state.  You would have to first
 332check which paths are conflicting with 'git status'
 333and after fixing them manually in your working tree, you would
 334stage the result as usual with 'git add':
 335
 336------------
 337$ git status | grep unmerged
 338unmerged: hello.c
 339$ edit hello.c
 340$ git add hello.c
 341------------
 342
 343After resolving conflicts and staging the result, `git ls-files -u`
 344would stop mentioning the conflicted path.  When you are done,
 345run `git commit` to finally record the merge:
 346
 347------------
 348$ git commit
 349------------
 350
 351As with the case to record your own changes, you can use `-a`
 352option to save typing.  One difference is that during a merge
 353resolution, you cannot use `git commit` with pathnames to
 354alter the order the changes are committed, because the merge
 355should be recorded as a single commit.  In fact, the command
 356refuses to run when given pathnames (but see `-i` option).
 357
 358
 359DISCUSSION
 360----------
 361
 362Though not required, it's a good idea to begin the commit message
 363with a single short (less than 50 character) line summarizing the
 364change, followed by a blank line and then a more thorough description.
 365Tools that turn commits into email, for example, use the first line
 366on the Subject: line and the rest of the commit in the body.

 369
 370ENVIRONMENT AND CONFIGURATION VARIABLES
 371---------------------------------------
 372The editor used to edit the commit log message will be chosen from the
 373GIT_EDITOR environment variable, the core.editor configuration variable, the
 374VISUAL environment variable, or the EDITOR environment variable (in that
 375order).  See linkgit:git-var[1] for details.
 376
 377HOOKS
 378-----
 379This command can run `commit-msg`, `prepare-commit-msg`, `pre-commit`,
 380and `post-commit` hooks.  See linkgit:githooks[5] for more
 381information.
