     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.
     8  #
     9  # To enable this hook, rename this file to "commit-msg".
    10  
    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.
    14  #
    15  # SOB=$(git var GIT_AUTHOR_IDENT | sed -n 's/^\(.*>\).*$/Signed-off-by: \1/p')
    16  # grep -qs "^$SOB" "$1" || echo "$SOB" >> "$1"
    17  
    18  # This example catches duplicate Signed-off-by lines.
