 The '''at''' scheduler is used to schedule a job for one-time-only running at a later date.  For comparison, the [[cron]] scheduler is used to schedule jobs for repeated execution at regular intervals.  One very handy use of the '''at''' scheduler is to schedule lengthy jobs to run in the background immediately - that way even if you need to (or are forced to) close your [[shell]] session, your job will continue running.
-The basic syntax of '''at''' is to type '''at''' followed by a time (specified in [[POSIX time format]]) you wish your new job to be executed.  Examples would be "at now" to run the job immediately, "at 0400" to run the job at 4 AM today, or "at 200410282300" to run the job at 11:00 PM on September 28th of 2004.  Once this is done, you enter interactive mode, and any further commands you type will be part of the '''at''' job scheduled.  Once you're done entering in commands to be scheduled, you press CTRL-D (aka the [[eof]] character) and the scheduler tells you what your job number is and what shell it will be executed with (typically /bin/sh by default).
