  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--long::
 113        When doing a dry-run, give the output in a the long-format.
 114        Implies `--dry-run`.
 115
 116-z::
 117--null::
 118        When showing `short` or `porcelain` status output, terminate
 119        entries in the status output with NUL, instead of LF. If no
 120        format is given, implies the `--porcelain` output format.
 121
 122-F <file>::
 123--file=<file>::
 124        Take the commit message from the given file.  Use '-' to
 125        read the message from the standard input.
 126
 127--author=<author>::
 128        Override the commit author. Specify an explicit author using the
 129        standard `A U Thor <author@example.com>` format. Otherwise <author>
 130        is assumed to be a pattern and is used to search for an existing
 131        commit by that author (i.e. rev-list --all -i --author=<author>);
 132        the commit author is then copied from the first such commit found.
 133
 134--date=<date>::
 135        Override the author date used in the commit.
 136
 137-m <msg>::
 138--message=<msg>::
 139        Use the given <msg> as the commit message.
 140
 141-t <file>::
 142--template=<file>::
 143        When editing the commit message, start the editor with the
 144        contents in the given file.  The `commit.template` configuration
 145        variable is often used to give this option implicitly to the
 146        command.  This mechanism can be used by projects that want to
 147        guide participants with some hints on what to write in the message
 148        in what order.  If the user exits the editor without editing the
 149        message, the commit is aborted.  This has no effect when a message
 150        is given by other means, e.g. with the `-m` or `-F` options.
 151
 152-s::
 153--signoff::
 154        Add Signed-off-by line by the committer at the end of the commit
 155        log message.
 156
 157-n::
 158--no-verify::
 159        This option bypasses the pre-commit and commit-msg hooks.
 160        See also linkgit:githooks[5].
 161
 162--allow-empty::
 163        Usually recording a commit that has the exact same tree as its
 164        sole parent commit is a mistake, and the command prevents you
 165        from making such a commit.  This option bypasses the safety, and
 166        is primarily for use by foreign SCM interface scripts.
 167
 168--allow-empty-message::
 169       Like --allow-empty this command is primarily for use by foreign
 170       SCM interface scripts. It allows you to create a commit with an
 171       empty commit message without using plumbing commands like
 172       linkgit:git-commit-tree[1].
 173
 174--cleanup=<mode>::
 175        This option sets how the commit message is cleaned up.
 176        The  '<mode>' can be one of 'verbatim', 'whitespace', 'strip',
 177        and 'default'. The 'default' mode will strip leading and
 178        trailing empty lines and #commentary from the commit message
 179        only if the message is to be edited. Otherwise only whitespace
 180        removed. The 'verbatim' mode does not change message at all,
 181        'whitespace' removes just leading/trailing whitespace lines
 182        and 'strip' removes both whitespace and commentary.
 183
 184-e::
 185--edit::
 186        The message taken from file with `-F`, command line with
 187        `-m`, and from file with `-C` are usually used as the
 188        commit log message unmodified.  This option lets you
 189        further edit the message taken from these sources.
 190
 191--no-edit::
 192        Use the selected commit message without launching an editor.
 193        For example, `git commit --amend --no-edit` amends a commit
 194        without changing its commit message.
 195
 196--amend::
 197        Used to amend the tip of the current branch. Prepare the tree
 198        object you would want to replace the latest commit as usual
 199        (this includes the usual -i/-o and explicit paths), and the
 200        commit log editor is seeded with the commit message from the
 201        tip of the current branch. The commit you create replaces the
 202        current tip -- if it was a merge, it will have the parents of
 203        the current tip as parents -- so the current top commit is
 204        discarded.
 205+
 206--
 207It is a rough equivalent for:
 208------
 209        $ git reset --soft HEAD^
 210        $ ... do something else to come up with the right tree ...
 211        $ git commit -c ORIG_HEAD
 212
 213------
 214but can be used to amend a merge commit.
 215--
 216+
 217You should understand the implications of rewriting history if you
 218amend a commit that has already been published.  (See the "RECOVERING
 219FROM UPSTREAM REBASE" section in linkgit:git-rebase[1].)
 220
 221--no-post-rewrite::
 222        Bypass the post-rewrite hook.
 223
 224-i::
 225--include::
 226        Before making a commit out of staged contents so far,
 227        stage the contents of paths given on the command line
 228        as well.  This is usually not what you want unless you
 229        are concluding a conflicted merge.
 230
 231-o::
 232--only::
 233        Make a commit only from the paths specified on the
 234        command line, disregarding any contents that have been
 235        staged so far. This is the default mode of operation of
 236        'git commit' if any paths are given on the command line,
 237        in which case this option can be omitted.
 238        If this option is specified together with '--amend', then
 239        no paths need to be specified, which can be used to amend
 240        the last commit without committing changes that have
 241        already been staged.
 242
 243-u[<mode>]::
 244--untracked-files[=<mode>]::
 245        Show untracked files.
 246+
 247The mode parameter is optional (defaults to 'all'), and is used to
 248specify the handling of untracked files; when -u is not used, the
 249default is 'normal', i.e. show untracked files and directories.
 250+
 251The possible options are:
 252+
 253        - 'no'     - Show no untracked files
 254        - 'normal' - Shows untracked files and directories
 255        - 'all'    - Also shows individual files in untracked directories.
 256+
 257The default can be changed using the status.showUntrackedFiles
 258configuration variable documented in linkgit:git-config[1].
 259
 260-v::
 261--verbose::
 262        Show unified diff between the HEAD commit and what
 263        would be committed at the bottom of the commit message
 264        template.  Note that this diff output doesn't have its
 265        lines prefixed with '#'.
 266
 267-q::
 268--quiet::
 269        Suppress commit summary message.
 270
 271--dry-run::
 272        Do not create a commit, but show a list of paths that are
 273        to be committed, paths with local changes that will be left
 274        uncommitted and paths that are untracked.
 275
 276--status::
 277        Include the output of linkgit:git-status[1] in the commit
 278        message template when using an editor to prepare the commit
 279        message.  Defaults to on, but can be used to override
 280        configuration variable commit.status.
 281
 282--no-status::
 283        Do not include the output of linkgit:git-status[1] in the
 284        commit message template when using an editor to prepare the
 285        default commit message.
 286
 287-S[<keyid>]::
 288--gpg-sign[=<keyid>]::
 289        GPG-sign commit.
 290
 291\--::
 292        Do not interpret any more arguments as options.
 293
 294<file>...::
 295        When files are given on the command line, the command
 296        commits the contents of the named files, without
 297        recording the changes already staged.  The contents of
 298        these files are also staged for the next commit on top
 299        of what have been staged before.

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