Classnotes | UNIX01 | RecentChanges | Preferences UNIX offers a very robust system by which programs and commands can be scheduled. The two main components of this system are the at suite of utilities and the cron system.
As with everything else, scheduled events must be run as a given user. The at suite is a scheduling system which will only run as the user which starts it. Cron, on the other hand, can be invoked both as individual users and system-wide.
