name : commit-msg.sample #!/bin/sh # # 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 }
