# An example hook script to check the commit log message.

# Called by "git commit" with one argument, the name of the file

# that has the commit message.  The hook should exit with non-zero

# status after issuing an appropriate message if it wants to stop the

# commit.  The hook is allowed to edit the commit message file.

#

# To enable this hook, rename this file to "commit-msg".

# Uncomment the below to add a Signed-off-by line to the message.

# Doing this in a hook is a bad idea in general, but the prepare-commit-msg

# hook is more suited to it.

#

# SOB=$(git var GIT_AUTHOR_IDENT | sed -n 's/^\(.*>\).*$/Signed-off-by: \1/p')

# grep -qs "^$SOB" "$1" || echo "$SOB" >> "$1"

# This example catches duplicate Signed-off-by lines.

test "" = "$(grep '^Signed-off-by: ' "$1" |

	 sort | uniq -c | sed -e '/^[ 	]*1[ 	]/d')" || {

	echo >&2 Duplicate Signed-off-by lines.

	exit 1
