#!/bin/sh## An example hook script to prepare the commit log message.# Called by "git commit" with the name of the file that has the# commit message, followed by the description of the commit# message's source. The hook's purpose is to edit the commit# message file. If the hook fails with a non-zero status,# the commit is aborted.## To enable this hook, rename this file to "prepare-commit-msg".# This hook includes three examples. The first one removes the# "# Please enter the commit message..." help message.## The second includes the output of "git diff --name-status -r"# into the message, just before the "git status" output. It is# commented because it doesn't cope with --amend or with squashed# commits.## The third example adds a Signed-off-by line to the message, that can# still be edited. This is rarely a good idea.COMMIT_MSG_FILE=$1COMMIT_SOURCE=$2SHA1=$3/usr/bin/perl -i.bak -ne 'print unless(m/^.
