Desktops and servers tend to have no power sensor, thus on_ac_power returns
255 ("unknown"). Thus, let's take any answer other than 1 ("battery") as
no contraindication to run gc.
If that tool returns "unknown", there's no point in querying other sources
as it already queried them, and is smarter than us (can handle multiple
adapters).

# An example hook script to verify if you are on battery, in case you
|
|
# are running Linux or OS X. Called by git-gc --auto with no arguments.
|
|
# The hook should exit with non-zero status after issuing an appropriate
|
|
# message if it wants to stop the auto repacking.
|
|
#
|
|
# This hook is stored in the contrib/hooks directory. Your distribution
|
|
# may have put this somewhere else. If you want to use this hook, you
|
|
# should make this script executable then link to it in the repository
|
|
# you would like to use it in.
|
|
#
|
|
# For example, if the hook is stored in
|
|
# /usr/share/git-core/contrib/hooks/pre-auto-gc-battery:
|
|
#
|
|
# cd /path/to/your/repository.git
|
|
# ln -sf /usr/share/git-core/contrib/hooks/pre-auto-gc-battery \
|

# hooks/pre-auto-gc
