  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--allow-empty-message::
 135       Like --allow-empty this command is primarily for use by foreign
 136       scm interface scripts. It allows you to create a commit with an
 137       empty commit message without using plumbing commands like
 138       linkgit:git-commit-tree[1].
 139
 140--cleanup=<mode>::
 141        This option sets how the commit message is cleaned up.
 142        The  '<mode>' can be one of 'verbatim', 'whitespace', 'strip',
 143        and 'default'. The 'default' mode will strip leading and
 144        trailing empty lines and #commentary from the commit message
 145        only if the message is to be edited. Otherwise only whitespace
 146        removed. The 'verbatim' mode does not change message at all,
 147        'whitespace' removes just leading/trailing whitespace lines
 148        and 'strip' removes both whitespace and commentary.
 149
 150-e::
 151--edit::
 152        The message taken from file with `-F`, command line with
 153        `-m`, and from file with `-C` are usually used as the
 154        commit log message unmodified.  This option lets you
 155        further edit the message taken from these sources.
 156
 157--amend::
 158        Used to amend the tip of the current branch. Prepare the tree
 159        object you would want to replace the latest commit as usual
 160        (this includes the usual -i/-o and explicit paths), and the
 161        commit log editor is seeded with the commit message from the
 162        tip of the current branch. The commit you create replaces the
 163        current tip -- if it was a merge, it will have the parents of
 164        the current tip as parents -- so the current top commit is
 165        discarded.
 166+
 167--
 168It is a rough equivalent for:
 169------
 170        $ git reset --soft HEAD^
 171        $ ... do something else to come up with the right tree ...
 172        $ git commit -c ORIG_HEAD
 173
 174------
 175but can be used to amend a merge commit.
 176--
 177+
 178You should understand the implications of rewriting history if you
 179amend a commit that has already been published.  (See the "RECOVERING
 180FROM UPSTREAM REBASE" section in linkgit:git-rebase[1].)
 181
 182-i::
 183--include::
 184        Before making a commit out of staged contents so far,
 185        stage the contents of paths given on the command line
 186        as well.  This is usually not what you want unless you
 187        are concluding a conflicted merge.
 188
 189-o::
 190--only::
 191        Make a commit only from the paths specified on the
 192        command line, disregarding any contents that have been
 193        staged so far. This is the default mode of operation of
 194        'git commit' if any paths are given on the command line,
 195        in which case this option can be omitted.
 196        If this option is specified together with '--amend', then
 197        no paths need to be specified, which can be used to amend
 198        the last commit without committing changes that have
 199        already been staged.
 200
 201-u[<mode>]::
 202--untracked-files[=<mode>]::
 203        Show untracked files (Default: 'all').
 204+
 205The mode parameter is optional, and is used to specify
 206the handling of untracked files.
 207+
 208The possible options are:
 209+
 210        - 'no'     - Show no untracked files
 211        - 'normal' - Shows untracked files and directories
 212        - 'all'    - Also shows individual files in untracked directories.
 213+
 214See linkgit:git-config[1] for configuration variable
 215used to change the default for when the option is not
 216specified.
 217
 218-v::
 219--verbose::
 220        Show unified diff between the HEAD commit and what
 221        would be committed at the bottom of the commit message
 222        template.  Note that this diff output doesn't have its
 223        lines prefixed with '#'.
 224
 225-q::
 226--quiet::
 227        Suppress commit summary message.
 228
 229--dry-run::
 230        Do not create a commit, but show a list of paths that are
 231        to be committed, paths with local changes that will be left
 232        uncommitted and paths that are untracked.
 233
 234--status::
 235        Include the output of linkgit:git-status[1] in the commit
 236        message template when using an editor to prepare the commit
 237        message.  Defaults to on, but can be used to override
 238        configuration variable commit.status.
 239
 240--no-status::
 241        Do not include the output of linkgit:git-status[1] in the
 242        commit message template when using an editor to prepare the
 243        default commit message.
 244
 245\--::
 246        Do not interpret any more arguments as options.
 247
 248<file>...::
 249        When files are given on the command line, the command
 250        commits the contents of the named files, without
 251        recording the changes already staged.  The contents of
 252        these files are also staged for the next commit on top
 253        of what have been staged before.

 258EXAMPLES
 259--------
 260When recording your own work, the contents of modified files in
 261your working tree are temporarily stored to a staging area
 262called the "index" with 'git add'.  A file can be
 263reverted back, only in the index but not in the working tree,
 264to that of the last commit with `git reset HEAD -- <file>`,
 265which effectively reverts 'git add' and prevents the changes to
 266this file from participating in the next commit.  After building
 267the state to be committed incrementally with these commands,
 268`git commit` (without any pathname parameter) is used to record what
 269has been staged so far.  This is the most basic form of the
 270command.  An example:
 271
 272------------
 273$ edit hello.c
 274$ git rm goodbye.c
 275$ git add hello.c
 276$ git commit
 277------------
 278
 279Instead of staging files after each individual change, you can
 280tell `git commit` to notice the changes to the files whose
 281contents are tracked in
 282your working tree and do corresponding `git add` and `git rm`
 283for you.  That is, this example does the same as the earlier
 284example if there is no other change in your working tree:
 285
 286------------
 287$ edit hello.c
 288$ rm goodbye.c
 289$ git commit -a
 290------------
 291
 292The command `git commit -a` first looks at your working tree,
 293notices that you have modified hello.c and removed goodbye.c,
 294and performs necessary `git add` and `git rm` for you.
 295
 296After staging changes to many files, you can alter the order the
 297changes are recorded in, by giving pathnames to `git commit`.
 298When pathnames are given, the command makes a commit that
 299only records the changes made to the named paths:
 300
 301------------
 302$ edit hello.c hello.h
 303$ git add hello.c hello.h
 304$ edit Makefile
 305$ git commit Makefile
 306------------
 307
 308This makes a commit that records the modification to `Makefile`.
 309The changes staged for `hello.c` and `hello.h` are not included
 310in the resulting commit.  However, their changes are not lost --
 311they are still staged and merely held back.  After the above
 312sequence, if you do:
 313
 314------------
 315$ git commit
 316------------
 317
 318this second commit would record the changes to `hello.c` and
 319`hello.h` as expected.
 320
 321After a merge (initiated by 'git merge' or 'git pull') stops
 322because of conflicts, cleanly merged
 323paths are already staged to be committed for you, and paths that
 324conflicted are left in unmerged state.  You would have to first
 325check which paths are conflicting with 'git status'
 326and after fixing them manually in your working tree, you would
 327stage the result as usual with 'git add':
 328
 329------------
 330$ git status | grep unmerged
 331unmerged: hello.c
 332$ edit hello.c
 333$ git add hello.c
 334------------
 335
 336After resolving conflicts and staging the result, `git ls-files -u`
 337would stop mentioning the conflicted path.  When you are done,
 338run `git commit` to finally record the merge:
 339
 340------------
 341$ git commit
 342------------
 343
 344As with the case to record your own changes, you can use `-a`
 345option to save typing.  One difference is that during a merge
 346resolution, you cannot use `git commit` with pathnames to
 347alter the order the changes are committed, because the merge
 348should be recorded as a single commit.  In fact, the command
 349refuses to run when given pathnames (but see `-i` option).
 350
 351
 352DISCUSSION
 353----------
 354
 355Though not required, it's a good idea to begin the commit message
 356with a single short (less than 50 character) line summarizing the
 357change, followed by a blank line and then a more thorough description.
 358Tools that turn commits into email, for example, use the first line
 359on the Subject: line and the rest of the commit in the body.

 362
 363ENVIRONMENT AND CONFIGURATION VARIABLES
 364---------------------------------------
 365The editor used to edit the commit log message will be chosen from the
 366GIT_EDITOR environment variable, the core.editor configuration variable, the
 367VISUAL environment variable, or the EDITOR environment variable (in that
 368order).  See linkgit:git-var[1] for details.
 369
 370HOOKS
 371-----
 372This command can run `commit-msg`, `prepare-commit-msg`, `pre-commit`,
 373and `post-commit` hooks.  See linkgit:githooks[5] for more
 374information.
