  16DESCRIPTION
  17-----------
  18Stores the current contents of the index in a new commit along
  19with a log message from the user describing the changes.
  20
  21The content to be added can be specified in several ways:
  22
  231. by using 'git-add' to incrementally "add" changes to the
  24   index before using the 'commit' command (Note: even modified
  25   files must be "added");
  26
  272. by using 'git-rm' to remove files from the working tree
  28   and the index, again before using the 'commit' command;
  29
  303. by listing files as arguments to the 'commit' command, in which
  31   case the commit will ignore changes staged in the index, and instead
  32   record the current content of the listed files (which must already
  33   be known to git);
  34
  354. by using the -a switch with the 'commit' command to automatically
  36   "add" changes from all known files (i.e. all files that are already
  37   listed in the index) and to automatically "rm" files in the index
  38   that have been removed from the working tree, and then perform the
  39   actual commit;
  40
  415. by using the --interactive switch with the 'commit' command to decide one
  42   by one which files should be part of the commit, before finalizing the
  43   operation.  Currently, this is done by invoking 'git-add --interactive'.
  44
  45The `--dry-run` option can be used to obtain a
  46summary of what is included by any of the above for the next
  47commit by giving the same set of parameters (options and paths).
  48
  49If you make a commit and then find a mistake immediately after
  50that, you can recover from it with 'git-reset'.
  51
  52
  53OPTIONS
  54-------
  55-a::
  56--all::
  57        Tell the command to automatically stage files that have
  58        been modified and deleted, but new files you have not
  59        told git about are not affected.
  60
  61-C <commit>::
  62--reuse-message=<commit>::
  63        Take an existing commit object, and reuse the log message
  64        and the authorship information (including the timestamp)
  65        when creating the commit.
  66
  67-c <commit>::
  68--reedit-message=<commit>::
  69        Like '-C', but with '-c' the editor is invoked, so that
  70        the user can further edit the commit message.
  71
  72--reset-author::
  73        When used with -C/-c/--amend options, declare that the
  74        authorship of the resulting commit now belongs of the committer.
  75        This also renews the author timestamp.
  76
  77-F <file>::
  78--file=<file>::
  79        Take the commit message from the given file.  Use '-' to
  80        read the message from the standard input.
  81
  82--author=<author>::
  83        Override the author name used in the commit.  You can use the
  84        standard `A U Thor <author@example.com>` format.  Otherwise,
  85        an existing commit that matches the given string and its author
  86        name is used.
  87
  88-m <msg>::
  89--message=<msg>::
  90        Use the given <msg> as the commit message.
  91
  92-t <file>::
  93--template=<file>::
  94        Use the contents of the given file as the initial version
  95        of the commit message. The editor is invoked and you can
  96        make subsequent changes. If a message is specified using
  97        the `-m` or `-F` options, this option has no effect. This
  98        overrides the `commit.template` configuration variable.
  99
 100-s::
 101--signoff::
 102        Add Signed-off-by line by the committer at the end of the commit
 103        log message.
 104
 105-n::
 106--no-verify::
 107        This option bypasses the pre-commit and commit-msg hooks.
 108        See also linkgit:githooks[5].
 109
 110--allow-empty::
 111        Usually recording a commit that has the exact same tree as its
 112        sole parent commit is a mistake, and the command prevents you
 113        from making such a commit.  This option bypasses the safety, and
 114        is primarily for use by foreign scm interface scripts.
 115
 116--cleanup=<mode>::
 117        This option sets how the commit message is cleaned up.
 118        The  '<mode>' can be one of 'verbatim', 'whitespace', 'strip',
 119        and 'default'. The 'default' mode will strip leading and
 120        trailing empty lines and #commentary from the commit message
 121        only if the message is to be edited. Otherwise only whitespace
 122        removed. The 'verbatim' mode does not change message at all,
 123        'whitespace' removes just leading/trailing whitespace lines
 124        and 'strip' removes both whitespace and commentary.
 125
 126-e::
 127--edit::
 128        The message taken from file with `-F`, command line with
 129        `-m`, and from file with `-C` are usually used as the
 130        commit log message unmodified.  This option lets you
 131        further edit the message taken from these sources.
 132
 133--amend::
 134        Used to amend the tip of the current branch. Prepare the tree
 135        object you would want to replace the latest commit as usual
 136        (this includes the usual -i/-o and explicit paths), and the
 137        commit log editor is seeded with the commit message from the
 138        tip of the current branch. The commit you create replaces the
 139        current tip -- if it was a merge, it will have the parents of
 140        the current tip as parents -- so the current top commit is
 141        discarded.
 142+
 143--
 144It is a rough equivalent for:
 145------
 146        $ git reset --soft HEAD^
 147        $ ... do something else to come up with the right tree ...
 148        $ git commit -c ORIG_HEAD
 149
 150------
 151but can be used to amend a merge commit.
 152--
 153+
 154You should understand the implications of rewriting history if you
 155amend a commit that has already been published.  (See the "RECOVERING
 156FROM UPSTREAM REBASE" section in linkgit:git-rebase[1].)
 157
 158-i::
 159--include::
 160        Before making a commit out of staged contents so far,
 161        stage the contents of paths given on the command line
 162        as well.  This is usually not what you want unless you
 163        are concluding a conflicted merge.
 164
 165-o::
 166--only::
 167        Make a commit only from the paths specified on the
 168        command line, disregarding any contents that have been
 169        staged so far. This is the default mode of operation of
 170        'git-commit' if any paths are given on the command line,
 171        in which case this option can be omitted.
 172        If this option is specified together with '--amend', then
 173        no paths need to be specified, which can be used to amend
 174        the last commit without committing changes that have
 175        already been staged.
 176
 177-u[<mode>]::
 178--untracked-files[=<mode>]::
 179        Show untracked files (Default: 'all').
 180+
 181The mode parameter is optional, and is used to specify
 182the handling of untracked files. The possible options are:
 183+
 184--
 185        - 'no'     - Show no untracked files
 186        - 'normal' - Shows untracked files and directories
 187        - 'all'    - Also shows individual files in untracked directories.
 188--
 189+
 190See linkgit:git-config[1] for configuration variable
 191used to change the default for when the option is not
 192specified.
 193
 194-v::
 195--verbose::
 196        Show unified diff between the HEAD commit and what
 197        would be committed at the bottom of the commit message
 198        template.  Note that this diff output doesn't have its
 199        lines prefixed with '#'.
 200
 201-q::
 202--quiet::
 203        Suppress commit summary message.
 204
 205--dry-run::
 206        Do not create a commit, but show a list of paths that are
 207        to be committed, paths with local changes that will be left
 208        uncommitted and paths that are untracked.
 209
 210\--::
 211        Do not interpret any more arguments as options.
 212
 213<file>...::
 214        When files are given on the command line, the command
 215        commits the contents of the named files, without
 216        recording the changes already staged.  The contents of
 217        these files are also staged for the next commit on top
 218        of what have been staged before.
 219
 220
 221EXAMPLES
 222--------
 223When recording your own work, the contents of modified files in
 224your working tree are temporarily stored to a staging area
 225called the "index" with 'git-add'.  A file can be
 226reverted back, only in the index but not in the working tree,
 227to that of the last commit with `git reset HEAD -- <file>`,
 228which effectively reverts 'git-add' and prevents the changes to
 229this file from participating in the next commit.  After building
 230the state to be committed incrementally with these commands,
 231`git commit` (without any pathname parameter) is used to record what
 232has been staged so far.  This is the most basic form of the
 233command.  An example:
 234
 235------------
 236$ edit hello.c
 237$ git rm goodbye.c
 238$ git add hello.c
 239$ git commit
 240------------
 241
 242Instead of staging files after each individual change, you can
 243tell `git commit` to notice the changes to the files whose
 244contents are tracked in
 245your working tree and do corresponding `git add` and `git rm`
 246for you.  That is, this example does the same as the earlier
 247example if there is no other change in your working tree:
 248
 249------------
 250$ edit hello.c
 251$ rm goodbye.c
 252$ git commit -a
 253------------
 254
 255The command `git commit -a` first looks at your working tree,
 256notices that you have modified hello.c and removed goodbye.c,
 257and performs necessary `git add` and `git rm` for you.
 258
 259After staging changes to many files, you can alter the order the
 260changes are recorded in, by giving pathnames to `git commit`.
 261When pathnames are given, the command makes a commit that
 262only records the changes made to the named paths:
 263
 264------------
 265$ edit hello.c hello.h
 266$ git add hello.c hello.h
 267$ edit Makefile
 268$ git commit Makefile
 269------------
 270
 271This makes a commit that records the modification to `Makefile`.
 272The changes staged for `hello.c` and `hello.h` are not included
 273in the resulting commit.  However, their changes are not lost --
 274they are still staged and merely held back.  After the above
 275sequence, if you do:
 276
 277------------
 278$ git commit
 279------------
 280
 281this second commit would record the changes to `hello.c` and
 282`hello.h` as expected.
 283
 284After a merge (initiated by 'git-merge' or 'git-pull') stops
 285because of conflicts, cleanly merged
 286paths are already staged to be committed for you, and paths that
 287conflicted are left in unmerged state.  You would have to first
 288check which paths are conflicting with 'git-status'
 289and after fixing them manually in your working tree, you would
 290stage the result as usual with 'git-add':
 291
 292------------
 293$ git status | grep unmerged
 294unmerged: hello.c
 295$ edit hello.c
 296$ git add hello.c
 297------------
 298
 299After resolving conflicts and staging the result, `git ls-files -u`
 300would stop mentioning the conflicted path.  When you are done,
 301run `git commit` to finally record the merge:
 302
 303------------
 304$ git commit
 305------------
 306
 307As with the case to record your own changes, you can use `-a`
 308option to save typing.  One difference is that during a merge
 309resolution, you cannot use `git commit` with pathnames to
 310alter the order the changes are committed, because the merge
 311should be recorded as a single commit.  In fact, the command
 312refuses to run when given pathnames (but see `-i` option).
 313
 314
 315DISCUSSION
 316----------
 317
 318Though not required, it's a good idea to begin the commit message
 319with a single short (less than 50 character) line summarizing the
 320change, followed by a blank line and then a more thorough description.
 321Tools that turn commits into email, for example, use the first line
 322on the Subject: line and the rest of the commit in the body.

 325
 326ENVIRONMENT AND CONFIGURATION VARIABLES
 327---------------------------------------
 328The editor used to edit the commit log message will be chosen from the
 329GIT_EDITOR environment variable, the core.editor configuration variable, the
 330VISUAL environment variable, or the EDITOR environment variable (in that
 331order).  See linkgit:git-var[1] for details.
 332
 333HOOKS
 334-----
 335This command can run `commit-msg`, `prepare-commit-msg`, `pre-commit`,
 336and `post-commit` hooks.  See linkgit:githooks[5] for more
 337information.
