NAME
       at, atrun - execute commands at a later time

SYNOPSIS
       at time [month day] [file]

EXAMPLES
       at 2315 Jan 31 myfile
			   # Myfile executed Jan 31 at 11:15 pm

       at 0900		   # Job input read from stdin

       at 0711 4 29	   # Read from stdin, exec on April 29

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.
