Hooks are little scripts you can place in `$GIT_DIR/hooks`
directory to trigger action at certain points. When
-'git-init' is run, a handful example hooks are copied in the
+'git-init' is run, a handful of example hooks are copied into the
`hooks` directory of the new repository, but by default they are
all disabled. To enable a hook, rename it by removing its `.sample`
suffix.
This document describes the currently defined hooks.
+HOOKS
+-----
+
applypatch-msg
---------------
+~~~~~~~~~~~~~~
This hook is invoked by 'git-am' script. It takes a single
parameter, the name of the file that holds the proposed commit
'commit-msg' hook, if the latter is enabled.
pre-applypatch
---------------
+~~~~~~~~~~~~~~
This hook is invoked by 'git-am'. It takes no parameter, and is
invoked after the patch is applied, but before a commit is made.
'pre-commit' hook, if the latter is enabled.
post-applypatch
----------------
+~~~~~~~~~~~~~~~
This hook is invoked by 'git-am'. It takes no parameter,
and is invoked after the patch is applied and a commit is made.
the outcome of 'git-am'.
pre-commit
-----------
+~~~~~~~~~~
This hook is invoked by 'git-commit', and can be bypassed
with `\--no-verify` option. It takes no parameter, and is
to modify the commit message.
prepare-commit-msg
-------------------
+~~~~~~~~~~~~~~~~~~
This hook is invoked by 'git-commit' right after preparing the
default log message, and before the editor is started.
out the `Conflicts:` part of a merge's commit message.
commit-msg
-----------
+~~~~~~~~~~
This hook is invoked by 'git-commit', and can be bypassed
with `\--no-verify` option. It takes a single parameter, the
"Signed-off-by" lines, and aborts the commit if one is found.
post-commit
------------
+~~~~~~~~~~~
This hook is invoked by 'git-commit'. It takes no
parameter, and is invoked after a commit is made.
the outcome of 'git-commit'.
pre-rebase
-----------
+~~~~~~~~~~
This hook is called by 'git-rebase' and can be used to prevent a branch
from getting rebased.
post-checkout
------------
+~~~~~~~~~~~~~
This hook is invoked when a 'git-checkout' is run after having updated the
worktree. The hook is given three parameters: the ref of the previous HEAD,
flag=1) or a file checkout (retrieving a file from the index, flag=0).
This hook cannot affect the outcome of 'git-checkout'.
+It is also run after 'git-clone', unless the --no-checkout (-n) option is
+used. The first parameter given to the hook is the null-ref, the second the
+ref of the new HEAD and the flag is always 1.
+
This hook can be used to perform repository validity checks, auto-display
differences from the previous HEAD if different, or set working dir metadata
properties.
post-merge
------------
+~~~~~~~~~~
This hook is invoked by 'git-merge', which happens when a 'git-pull'
is done on a local repository. The hook takes a single parameter, a status

This hook is invoked by 'git-receive-pack' on the remote repository,
which happens when a 'git-push' is done on a local repository.

update
-------
+~~~~~~
This hook is invoked by 'git-receive-pack' on the remote repository,
which happens when a 'git-push' is done on a local repository.
This hook can be used to prevent 'forced' update on certain refs by
making sure that the object name is a commit object that is a
descendant of the commit object named by the old object name.

It could also be used to log the old..new status. However, it
does not know the entire set of branches, so it would end up
for the user.
