- AT(1) Minix Programmer's Manual AT(1)
- 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.
- SEE ALSO
- cron(8).
