-a, --all
    Tell the command to automatically stage files that have been modified and deleted, but new files you
    have not told git about are not affected.

-p, --patch
    Use the interactive patch selection interface to chose which changes to commit. See git-add(1) for
    details.

-C <commit>, --reuse-message=<commit>
    Take an existing commit object, and reuse the log message and the authorship information (including
    the timestamp) when creating the commit.

-c <commit>, --reedit-message=<commit>
    Like -C, but with -c the editor is invoked, so that the user can further edit the commit message.

--fixup=<commit>
    Construct a commit message for use with rebase --autosquash. The commit message will be the subject
    line from the specified commit with a prefix of "fixup! ". See git-rebase(1) for details.

--squash=<commit>
    Construct a commit message for use with rebase --autosquash. The commit message subject line is taken
    from the specified commit with a prefix of "squash! ". Can be used with additional commit message
    options (-m/-c/-C/-F). See git-rebase(1) for details.

--reset-author
    When used with -C/-c/--amend options, or when committing after a a conflicting cherry-pick, declare
    that the authorship of the resulting commit now belongs of the committer. This also renews the author
    timestamp.

--short
    When doing a dry-run, give the output in the short-format. See git-status(1) for details. Implies
    --dry-run.

--porcelain
    When doing a dry-run, give the output in a porcelain-ready format. See git-status(1) for details.
    Implies --dry-run.

-z
    When showing short or porcelain status output, terminate entries in the status output with NUL,
    instead of LF. If no format is given, implies the --porcelain output format.

-F <file>, --file=<file>
    Take the commit message from the given file. Use - to read the message from the standard input.

--author=<author>
    Override the commit author. Specify an explicit author using the standard A U Thor
    <author@example.com[1]> format. Otherwise <author> is assumed to be a pattern and is used to search
    for an existing commit by that author (i.e. rev-list --all -i --author=<author>); the commit author
    is then copied from the first such commit found.

--date=<date>
    Override the author date used in the commit.

-m <msg>, --message=<msg>
    Use the given <msg> as the commit message.

-t <file>, --template=<file>
    Use the contents of the given file as the initial version of the commit message. The editor is
    invoked and you can make subsequent changes. If a message is specified using the -m or -F options,
    this option has no effect. This overrides the commit.template configuration variable.

-s, --signoff
    Add Signed-off-by line by the committer at the end of the commit log message.

-n, --no-verify
    This option bypasses the pre-commit and commit-msg hooks. See also githooks(5).

--allow-empty
    Usually recording a commit that has the exact same tree as its sole parent commit is a mistake, and
    the command prevents you from making such a commit. This option bypasses the safety, and is primarily
    for use by foreign SCM interface scripts.

--allow-empty-message
    Like --allow-empty this command is primarily for use by foreign SCM interface scripts. It allows you
    to create a commit with an empty commit message without using plumbing commands like git-commit-
    tree(1).

--cleanup=<mode>
    This option sets how the commit message is cleaned up. The <mode> can be one of verbatim, whitespace,
    strip, and default. The default mode will strip leading and trailing empty lines and #commentary from
    the commit message only if the message is to be edited. Otherwise only whitespace removed. The
    verbatim mode does not change message at all, whitespace removes just leading/trailing whitespace
    lines and strip removes both whitespace and commentary.

-e, --edit
    The message taken from file with -F, command line with -m, and from file with -C are usually used as
    the commit log message unmodified. This option lets you further edit the message taken from these
    sources.

--amend
    Used to amend the tip of the current branch. Prepare the tree object you would want to replace the
    latest commit as usual (this includes the usual -i/-o and explicit paths), and the commit log editor
    is seeded with the commit message from the tip of the current branch. The commit you create replaces
    the current tip — if it was a merge, it will have the parents of the current tip as parents — so the
    current top commit is discarded.

    It is a rough equivalent for:

                       $ git reset --soft HEAD^
                       $ ... do something else to come up with the right tree ...
                       $ git commit -c ORIG_HEAD

           but can be used to amend a merge commit.

           You should understand the implications of rewriting history if you amend a commit that has already
           been published. (See the "RECOVERING FROM UPSTREAM REBASE" section in git-rebase(1).)

-i, --include
    Before making a commit out of staged contents so far, stage the contents of paths given on the
    command line as well. This is usually not what you want unless you are concluding a conflicted merge.

-o, --only
    Make a commit only from the paths specified on the command line, disregarding any contents that have
    been staged so far. This is the default mode of operation of git commit if any paths are given on the
    command line, in which case this option can be omitted. If this option is specified together with
    --amend, then no paths need to be specified, which can be used to amend the last commit without
    committing changes that have already been staged.

-u[<mode>], --untracked-files[=<mode>]
    Show untracked files.

    The mode parameter is optional (defaults to all), and is used to specify the handling of untracked
    files; when -u is not used, the default is normal, i.e. show untracked files and directories.

    The possible options are:

        no - Show no untracked files

        normal - Shows untracked files and directories

        all - Also shows individual files in untracked directories.

        The default can be changed using the status.showUntrackedFiles configuration variable documented
        in git-config(1).

-v, --verbose
    Show unified diff between the HEAD commit and what would be committed at the bottom of the commit
    message template. Note that this diff output doesn’t have its lines prefixed with #.

-q, --quiet
    Suppress commit summary message.

--dry-run
    Do not create a commit, but show a list of paths that are to be committed, paths with local changes
    that will be left uncommitted and paths that are untracked.

--status
    Include the output of git-status(1) in the commit message template when using an editor to prepare
    the commit message. Defaults to on, but can be used to override configuration variable commit.status.

--no-status
    Do not include the output of git-status(1) in the commit message template when using an editor to
    prepare the default commit message.

<file>...
    When files are given on the command line, the command commits the contents of the named files,
    without recording the changes already staged. The contents of these files are also staged for the
    next commit on top of what have been staged before.
