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, rename this file to "commit-msg".
11 # Uncomment the below to add a Signed-off-by line to the message.
12 # Doing this in a hook is a bad idea in general, but the prepare-commit-msg
13 # hook is more suited to it.
15 # SOB=$(git var GIT_AUTHOR_IDENT | sed -n 's/^\(.*>\).*$/Signed-off-by: \1/p')
16 # grep -qs "^$SOB" "$1" || echo "$SOB" >> "$1"
18 # This example catches duplicate Signed-off-by lines.
20 test "" = "$(grep '^Signed-off-by: ' "$1" |
21 sort | uniq -c | sed -e '/^[ ]*1[ ]/d')" || {
22 echo >&2 Duplicate Signed-off-by lines.
