contrib/hooks/pre-auto-gc-battery

   1 #!/bin/sh
   2 #
   3 # An example hook script to verify if you are on battery, in case you
   4 # are running Linux. Called by git-gc --auto with no arguments. The hook
   5 # should exit with non-zero status after issuing an appropriate message
   6 # 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 # chmod a+x pre-auto-gc-battery
  17 # cd /path/to/your/repository.git
  18 # ln -sf /usr/share/git-core/contrib/hooks/pre-auto-gc-battery \
  19 #       hooks/pre-auto-gc
