This command checks for the last web or Git access an application has had, then records it in the gear operations directory. Running this command regularly in a cron job allows automatic idling of stale gears.
Example 9.5. A Cron auto-idler Script
run the last-access compiler hourly run the auto-idler twice daily and idle anything stale for 24 hours
# run the last-access compiler hourly

# run the auto-idler twice daily and idle anything stale for 24 hours
