   1#!/bin/sh
   2#
   3# An example hook script to verify if you are on battery, in case you
   4# are running Linux or OS X. Called by git-gc --auto with no arguments.
   5# The hook should exit with non-zero status after issuing an appropriate
   6# message if it wants to stop the auto repacking.
   7#
   8# This hook is stored in the contrib/hooks directory. Your distribution
   9# may have put this somewhere else. If you want to use this hook, you
  10# should make this script executable then link to it in the repository
  11# you would like to use it in.
  12#
  13# For example, if the hook is stored in
  14# /usr/share/git-core/contrib/hooks/pre-auto-gc-battery:
  15#
  16# cd /path/to/your/repository.git
  17# ln -sf /usr/share/git-core/contrib/hooks/pre-auto-gc-battery \
  18#       hooks/pre-auto-gc
