sync-community-history.sh

#!/bin/bash -xve

# This is a utility script that I run in a cron job, locally. It syncs the live
# community taskcluster entities with the community-history git repository.
# This allows us to crudely track changes to taskcluster entity definitions
# (clients, hooks, roles, worker pools).

# My cron job looks like this:
#  02,07,12,17,22,27,32,37,42,47,52,57 * * * * /Users/pmoore/git/mozilla/sync-community-history.sh > ~/sync-community-history.log 2>&1

# Note, the 'say' command is part of macOS. I prefer my computer to audibly say
# what it is doing, and if there is a problem, so that I do not need to
# routinely check logs. I just hear about problems (literally) if they occur.
