3 # An example hook script to check the commit log message.
4 # Called by git-commit with one argument, the name of the file
5 # that has the commit message. The hook should exit with non-zero
6 # status after issuing an appropriate message if it wants to stop the
7 # commit. The hook is allowed to edit the commit message file.
9 # To enable this hook, make this file executable.
11 # Uncomment the below to add a Signed-off-by line to the message.
12 # SOB=$(git var GIT_AUTHOR_IDENT | sed -n 's/^\(.*>\).*$/Signed-off-by: \1/p')
13 # grep -qs "^$SOB" "$1" || echo "$SOB" >> "$1"
15 # This example catches duplicate Signed-off-by lines.

18 sort | uniq -c | sed -e '/^[ ]*1[ ]/d')" || {
19 echo >&2 Duplicate Signed-off-by lines.
