Scheduling tasks with launchd

You can use launchd instead of cron to schedule tasks. With launchd, if a task is

skipped because the computer is shut o or asleep, the task is added to the queue

when the computer comes back online. To use launchd to schedule timer-based jobs,

use the StartCalendarInterval or StartInterval key.

For more information about launchd, see the launchd man page.
