AT(1)

NAME
at, atrun - execute commands at a later time

SYNOPSIS
at time [month day] [file]

EXAMPLES

DESCRIPTION

At prepares a file to be executed later at the specified time by creating a special entry in /usr/spool/at. The program atrun should be started periodically, for example, every minute by cron. Atrun checks to see if any files in /usr/spool/at should now be run, and if so, it runs them and then puts them in /usr/spool/at/past. The name of the file created in /usr/spool/at by at is YY.DDD.HHMM.UU (where YY, DDD, HH, and MM give the time to execute and UU is a unique number). Note that when the command runs, it will not be able to use stdin or stdout unless specifically redirected. In the first example above, it might be necessary to put >/dev/log on some lines in the shell script myfile. The same holds for the commands typed directly to at.
