   1 #!/bin/sh
   2 #
   3 # An example hook script to prepare the commit log message.
   4 # Called by "git commit" with the name of the file that has the
   5 # commit message, followed by the description of the commit
   6 # message's source.  The hook's purpose is to edit the commit
   7 # message file.  If the hook fails with a non-zero status,
   8 # the commit is aborted.
   9 #
  10 # To enable this hook, rename this file to "prepare-commit-msg".
  11
  12 # This hook includes three examples.  The first comments out the
  13 # "Conflicts:" part of a merge commit.
  14 #
  15 # The second includes the output of "git diff --name-status -r"
  16 # into the message, just before the "git status" output.  It is
  17 # commented because it doesn't cope with --amend or with squashed
  18 # commits.
  19 #
  20 # The third example adds a Signed-off-by line to the message, that can
  21 # still be edited.  This is rarely a good idea.
