# 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.
