   2#
   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# 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.
