  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--reset-author::
  74        When used with -C/-c/--amend options, declare that the
  75        authorship of the resulting commit now belongs of the committer.
  76        This also renews the author timestamp.
  77
  78--short::
  79        When doing a dry-run, give the output in the short-format. See
  80        linkgit:git-status[1] for details. Implies `--dry-run`.
  81
  82--porcelain::
  83        When doing a dry-run, give the output in a porcelain-ready
  84        format. See linkgit:git-status[1] for details. Implies
  85        `--dry-run`.
  86
  87-z::
  88        When showing `short` or `porcelain` status output, terminate
  89        entries in the status output with NUL, instead of LF. If no
  90        format is given, implies the `--porcelain` output format.
  91
  92-F <file>::
  93--file=<file>::
  94        Take the commit message from the given file.  Use '-' to
  95        read the message from the standard input.
  96
  97--author=<author>::
  98        Override the author name used in the commit.  You can use the
  99        standard `A U Thor <author@example.com>` format.  Otherwise,
 100        an existing commit that matches the given string and its author
 101        name is used.
 102
 103--date=<date>::
 104        Override the author date used in the commit.
 105
 106-m <msg>::
 107--message=<msg>::
 108        Use the given <msg> as the commit message.
 109
 110-t <file>::
 111--template=<file>::
 112        Use the contents of the given file as the initial version
 113        of the commit message. The editor is invoked and you can
 114        make subsequent changes. If a message is specified using
 115        the `-m` or `-F` options, this option has no effect. This
 116        overrides the `commit.template` configuration variable.
 117
 118-s::
 119--signoff::
 120        Add Signed-off-by line by the committer at the end of the commit
 121        log message.
 122
 123-n::
 124--no-verify::
 125        This option bypasses the pre-commit and commit-msg hooks.
 126        See also linkgit:githooks[5].
 127
 128--allow-empty::
 129        Usually recording a commit that has the exact same tree as its
 130        sole parent commit is a mistake, and the command prevents you
 131        from making such a commit.  This option bypasses the safety, and
 132        is primarily for use by foreign scm interface scripts.
 133
 134--cleanup=<mode>::
 135        This option sets how the commit message is cleaned up.
 136        The  '<mode>' can be one of 'verbatim', 'whitespace', 'strip',
 137        and 'default'. The 'default' mode will strip leading and
 138        trailing empty lines and #commentary from the commit message
 139        only if the message is to be edited. Otherwise only whitespace
 140        removed. The 'verbatim' mode does not change message at all,
 141        'whitespace' removes just leading/trailing whitespace lines
 142        and 'strip' removes both whitespace and commentary.
 143
 144-e::
 145--edit::
 146        The message taken from file with `-F`, command line with
 147        `-m`, and from file with `-C` are usually used as the
 148        commit log message unmodified.  This option lets you
 149        further edit the message taken from these sources.
 150
 151--amend::
 152        Used to amend the tip of the current branch. Prepare the tree
 153        object you would want to replace the latest commit as usual
 154        (this includes the usual -i/-o and explicit paths), and the
 155        commit log editor is seeded with the commit message from the
 156        tip of the current branch. The commit you create replaces the
 157        current tip -- if it was a merge, it will have the parents of
 158        the current tip as parents -- so the current top commit is
 159        discarded.
 160+
 161--
 162It is a rough equivalent for:
 163------
 164        $ git reset --soft HEAD^
 165        $ ... do something else to come up with the right tree ...
 166        $ git commit -c ORIG_HEAD
 167
 168------
 169but can be used to amend a merge commit.
 170--
 171+
 172You should understand the implications of rewriting history if you
 173amend a commit that has already been published.  (See the "RECOVERING
 174FROM UPSTREAM REBASE" section in linkgit:git-rebase[1].)
 175
 176-i::
 177--include::
 178        Before making a commit out of staged contents so far,
 179        stage the contents of paths given on the command line
 180        as well.  This is usually not what you want unless you
 181        are concluding a conflicted merge.
 182
 183-o::
 184--only::
 185        Make a commit only from the paths specified on the
 186        command line, disregarding any contents that have been
 187        staged so far. This is the default mode of operation of
 188        'git commit' if any paths are given on the command line,
 189        in which case this option can be omitted.
 190        If this option is specified together with '--amend', then
 191        no paths need to be specified, which can be used to amend
 192        the last commit without committing changes that have
 193        already been staged.
 194
 195-u[<mode>]::
 196--untracked-files[=<mode>]::
 197        Show untracked files (Default: 'all').
 198+
 199The mode parameter is optional, and is used to specify
 200the handling of untracked files.
 201+
 202The possible options are:
 203+
 204        - 'no'     - Show no untracked files
 205        - 'normal' - Shows untracked files and directories
 206        - 'all'    - Also shows individual files in untracked directories.
 207+
 208See linkgit:git-config[1] for configuration variable
 209used to change the default for when the option is not
 210specified.
 211
 212-v::
 213--verbose::
 214        Show unified diff between the HEAD commit and what
 215        would be committed at the bottom of the commit message
 216        template.  Note that this diff output doesn't have its
 217        lines prefixed with '#'.
 218
 219-q::
 220--quiet::
 221        Suppress commit summary message.
 222
 223--dry-run::
 224        Do not create a commit, but show a list of paths that are
 225        to be committed, paths with local changes that will be left
 226        uncommitted and paths that are untracked.
 227
 228--status::
 229        Include the output of linkgit:git-status[1] in the commit
 230        message template when using an editor to prepare the commit
 231        message.  Defaults to on, but can be used to override
 232        configuration variable commit.status.
 233
 234--no-status::
 235        Do not include the output of linkgit:git-status[1] in the
 236        commit message template when using an editor to prepare the
 237        default commit message.
 238
 239\--::
 240        Do not interpret any more arguments as options.
 241
 242<file>...::
 243        When files are given on the command line, the command
 244        commits the contents of the named files, without
 245        recording the changes already staged.  The contents of
 246        these files are also staged for the next commit on top
 247        of what have been staged before.

 252EXAMPLES
 253--------
 254When recording your own work, the contents of modified files in
 255your working tree are temporarily stored to a staging area
 256called the "index" with 'git add'.  A file can be
 257reverted back, only in the index but not in the working tree,
 258to that of the last commit with `git reset HEAD -- <file>`,
 259which effectively reverts 'git add' and prevents the changes to
 260this file from participating in the next commit.  After building
 261the state to be committed incrementally with these commands,
 262`git commit` (without any pathname parameter) is used to record what
 263has been staged so far.  This is the most basic form of the
 264command.  An example:
 265
 266------------
 267$ edit hello.c
 268$ git rm goodbye.c
 269$ git add hello.c
 270$ git commit
 271------------
 272
 273Instead of staging files after each individual change, you can
 274tell `git commit` to notice the changes to the files whose
 275contents are tracked in
 276your working tree and do corresponding `git add` and `git rm`
 277for you.  That is, this example does the same as the earlier
 278example if there is no other change in your working tree:
 279
 280------------
 281$ edit hello.c
 282$ rm goodbye.c
 283$ git commit -a
 284------------
 285
 286The command `git commit -a` first looks at your working tree,
 287notices that you have modified hello.c and removed goodbye.c,
 288and performs necessary `git add` and `git rm` for you.
 289
 290After staging changes to many files, you can alter the order the
 291changes are recorded in, by giving pathnames to `git commit`.
 292When pathnames are given, the command makes a commit that
 293only records the changes made to the named paths:
 294
 295------------
 296$ edit hello.c hello.h
 297$ git add hello.c hello.h
 298$ edit Makefile
 299$ git commit Makefile
 300------------
 301
 302This makes a commit that records the modification to `Makefile`.
 303The changes staged for `hello.c` and `hello.h` are not included
 304in the resulting commit.  However, their changes are not lost --
 305they are still staged and merely held back.  After the above
 306sequence, if you do:
 307
 308------------
 309$ git commit
 310------------
 311
 312this second commit would record the changes to `hello.c` and
 313`hello.h` as expected.
 314
 315After a merge (initiated by 'git merge' or 'git pull') stops
 316because of conflicts, cleanly merged
 317paths are already staged to be committed for you, and paths that
 318conflicted are left in unmerged state.  You would have to first
 319check which paths are conflicting with 'git status'
 320and after fixing them manually in your working tree, you would
 321stage the result as usual with 'git add':
 322
 323------------
 324$ git status | grep unmerged
 325unmerged: hello.c
 326$ edit hello.c
 327$ git add hello.c
 328------------
 329
 330After resolving conflicts and staging the result, `git ls-files -u`
 331would stop mentioning the conflicted path.  When you are done,
 332run `git commit` to finally record the merge:
 333
 334------------
 335$ git commit
 336------------
 337
 338As with the case to record your own changes, you can use `-a`
 339option to save typing.  One difference is that during a merge
 340resolution, you cannot use `git commit` with pathnames to
 341alter the order the changes are committed, because the merge
 342should be recorded as a single commit.  In fact, the command
 343refuses to run when given pathnames (but see `-i` option).
 344
 345
 346DISCUSSION
 347----------
 348
 349Though not required, it's a good idea to begin the commit message
 350with a single short (less than 50 character) line summarizing the
 351change, followed by a blank line and then a more thorough description.
 352Tools that turn commits into email, for example, use the first line
 353on the Subject: line and the rest of the commit in the body.

 356
 357ENVIRONMENT AND CONFIGURATION VARIABLES
 358---------------------------------------
 359The editor used to edit the commit log message will be chosen from the
 360GIT_EDITOR environment variable, the core.editor configuration variable, the
 361VISUAL environment variable, or the EDITOR environment variable (in that
 362order).  See linkgit:git-var[1] for details.
 363
 364HOOKS
 365-----
 366This command can run `commit-msg`, `prepare-commit-msg`, `pre-commit`,
 367and `post-commit` hooks.  See linkgit:githooks[5] for more
 368information.
