AT(1)                       General Commands Manual                      AT(1)

NAME
       at - 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 cron daemon takes  care
       of   executing   these  jobs.   It  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  standard  input  unless
       specifically  redirected.   Standard output will be mailed to the owner
       of the job.
