3 # An example hook script to prepare the commit log message.
4 # Called by "git commit" with the name of the file that has the
5 # commit message, followed by the description of the commit
6 # message's source. The hook's purpose is to edit the commit
7 # message file. If the hook fails with a non-zero status,
8 # the commit is aborted.
10 # To enable this hook, rename this file to "prepare-commit-msg".
12 # This hook includes three examples. The first one removes the
13 # "# Please enter the commit message..." help message.
15 # The second includes the output of "git diff --name-status -r"
16 # into the message, just before the "git status" output. It is
17 # commented because it doesn't cope with --amend or with squashed
18 # commits.
20 # The third example adds a Signed-off-by line to the message, that can
21 # still be edited. This is rarely a good idea.
