#!/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 comments out the# "Conflicts:" part of a merge commit.## 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.case "$2,$3" inmerge,)/usr/bin/perl -i.bak -ne 's/^/# /, s/^# #/#/ if /^Conflicts/ .. /#/; print' "$1" ;;# ,|template,)# /usr/bin/perl -i.bak -pe '# print "\n" . `git diff --cached --name-status -r`# if /^#/ && $first++ == 0' "$1" ;;*) ;;esac# SOB=$(git var GIT_AUTHOR_IDENT | sed -n 's/^\(.*>\).*$/Signed-off-by: \1/p')# grep -qs "^$SOB" "$1" || echo "$SOB" >> "$1"
