Questions tagged [at-job]

"at" is a classic Unix command that read commands from standard input (or a specified file) which are to be executed at a later time, using /bin/sh. Use this tag for questions related to programmatic use of "at"; trouble shooting and general usage questions might be better suited for Super User or Unix & Linux.

at is used to schedule commands for one-time execution, as opposed to jobs, which are run at regular intervals.
