  16DESCRIPTION
  17-----------
  18Use 'git commit' when you want to record your changes into the repository
  19along with a log message describing what the commit is about. All changes
  20to be committed must be explicitly identified using one of the following
  21methods:
  22
  231. by using gitlink:git-add[1] to incrementally "add" changes to the
  24   next commit before using the 'commit' command (Note: even modified
  25   files must be "added");
  26
  272. by using gitlink:git-rm[1] to identify content removal for the next
  28   commit, again before using the 'commit' command;
  29
  303. by directly listing files containing changes to be committed as arguments
  31   to the 'commit' command, in which cases only those files alone will be
  32   considered for the commit;
  33
  344. by using the -a switch with the 'commit' command to automatically "add"
  35   changes from all known files i.e. files that have already been committed
  36   before, and to automatically "rm" files that have been
  37   removed from the working tree, and perform the actual commit.
  38
  395. by using the --interactive switch with the 'commit' command to decide one
  40   by one which files should be part of the commit, before finalizing the
  41   operation.  Currently, this is done by invoking `git-add --interactive`.
  42
  43The gitlink:git-status[1] command can be used to obtain a
  44summary of what is included by any of the above for the next
  45commit by giving the same set of parameters you would give to
  46this command.
  47
  48If you make a commit and then found a mistake immediately after
  49that, you can recover from it with gitlink:git-reset[1].

  52OPTIONS
  53-------
  54-a|--all::
  55        Tell the command to automatically stage files that have
  56        been modified and deleted, but new files you have not
  57        told git about are not affected.
  58
  59-c or -C <commit>::
  60        Take existing commit object, and reuse the log message
  61        and the authorship information (including the timestamp)
  62        when creating the commit.  With '-C', the editor is not
  63        invoked; with '-c' the user can further edit the commit
  64        message.
  65
  66-F <file>::
  67        Take the commit message from the given file.  Use '-' to
  68        read the message from the standard input.
  69
  70--author <author>::
  71        Override the author name used in the commit.  Use
  72        `A U Thor <author@example.com>` format.
  73
  74-m <msg>::
  75        Use the given <msg> as the commit message.
  76
  77-s|--signoff::
  78        Add Signed-off-by line at the end of the commit message.
  79
  80--no-verify::
  81        This option bypasses the pre-commit hook.
  82        See also link:hooks.html[hooks].
  83
  84-e|--edit::
  85        The message taken from file with `-F`, command line with
  86        `-m`, and from file with `-C` are usually used as the
  87        commit log message unmodified.  This option lets you
  88        further edit the message taken from these sources.
  89
  90--amend::
  91
  92        Used to amend the tip of the current branch. Prepare the tree
  93        object you would want to replace the latest commit as usual
  94        (this includes the usual -i/-o and explicit paths), and the
  95        commit log editor is seeded with the commit message from the
  96        tip of the current branch. The commit you create replaces the
  97        current tip -- if it was a merge, it will have the parents of
  98        the current tip as parents -- so the current top commit is
  99        discarded.

 101--
 102It is a rough equivalent for:
 103------
 104        $ git reset --soft HEAD^
 105        $ ... do something else to come up with the right tree ...
 106        $ git commit -c ORIG_HEAD
 107
 108------
 109but can be used to amend a merge commit.
 110--
 111
 112-i|--include::
 113        Before making a commit out of staged contents so far,
 114        stage the contents of paths given on the command line
 115        as well.  This is usually not what you want unless you
 116        are concluding a conflicted merge.
 117
 118-q|--quiet::
 119        Suppress commit summary message.
 120
 121\--::
 122        Do not interpret any more arguments as options.
 123
 124<file>...::
 125        When files are given on the command line, the command
 126        commits the contents of the named files, without
 127        recording the changes already staged.  The contents of
 128        these files are also staged for the next commit on top
 129        of what have been staged before.
 130
 131
 132EXAMPLES
 133--------
 134When recording your own work, the contents of modified files in
 135your working tree are temporarily stored to a staging area
 136called the "index" with gitlink:git-add[1].  Removal
 137of a file is staged with gitlink:git-rm[1].  After building the
 138state to be committed incrementally with these commands, `git
 139commit` (without any pathname parameter) is used to record what
 140has been staged so far.  This is the most basic form of the
 141command.  An example:
 142
 143------------
 144$ edit hello.c
 145$ git rm goodbye.c
 146$ git add hello.c
 147$ git commit
 148------------
 149
 150Instead of staging files after each individual change, you can
 151tell `git commit` to notice the changes to the files whose
 152contents are tracked in
 153your working tree and do corresponding `git add` and `git rm`
 154for you.  That is, this example does the same as the earlier
 155example if there is no other change in your working tree:
 156
 157------------
 158$ edit hello.c
 159$ rm goodbye.c
 160$ git commit -a
 161------------
 162
 163The command `git commit -a` first looks at your working tree,
 164notices that you have modified hello.c and removed goodbye.c,
 165and performs necessary `git add` and `git rm` for you.
 166
 167After staging changes to many files, you can alter the order the
 168changes are recorded in, by giving pathnames to `git commit`.
 169When pathnames are given, the command makes a commit that
 170only records the changes made to the named paths:
 171
 172------------
 173$ edit hello.c hello.h
 174$ git add hello.c hello.h
 175$ edit Makefile
 176$ git commit Makefile
 177------------
 178
 179This makes a commit that records the modification to `Makefile`.
 180The changes staged for `hello.c` and `hello.h` are not included
 181in the resulting commit.  However, their changes are not lost --
 182they are still staged and merely held back.  After the above
 183sequence, if you do:
 184
 185------------
 186$ git commit
 187------------
 188
 189this second commit would record the changes to `hello.c` and
 190`hello.h` as expected.
 191
 192After a merge (initiated by either gitlink:git-merge[1] or
 193gitlink:git-pull[1]) stops because of conflicts, cleanly merged
 194paths are already staged to be committed for you, and paths that
 195conflicted are left in unmerged state.  You would have to first
 196check which paths are conflicting with gitlink:git-status[1]
 197and after fixing them manually in your working tree, you would
 198stage the result as usual with gitlink:git-add[1]:
 199
 200------------
 201$ git status | grep unmerged
 202unmerged: hello.c
 203$ edit hello.c
 204$ git add hello.c
 205------------
 206
 207After resolving conflicts and staging the result, `git ls-files -u`
 208would stop mentioning the conflicted path.  When you are done,
 209run `git commit` to finally record the merge:
 210
 211------------
 212$ git commit
 213------------
 214
 215As with the case to record your own changes, you can use `-a`
 216option to save typing.  One difference is that during a merge
 217resolution, you cannot use `git commit` with pathnames to
 218alter the order the changes are committed, because the merge
 219should be recorded as a single commit.  In fact, the command
 220refuses to run when given pathnames (but see `-i` option).

 223DISCUSSION
 224----------
 225
 226Though not required, it's a good idea to begin the commit message
 227with a single short (less than 50 character) line summarizing the
 228change, followed by a blank line and then a more thorough description.
 229Tools that turn commits into email, for example, use the first line
 230on the Subject: line and the rest of the commit in the body.
