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.
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.
13 # For example, if the hook is stored in
14 # /usr/share/git-core/contrib/hooks/pre-auto-gc-battery:
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 \
