   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, make this file executable.
  10
  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"
  14
  15 # This example catches duplicate Signed-off-by lines.
