- # 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.
