ATRUN(8)                OpenBSD System Manager's Manual               ATRUN(8)

     atrun - run jobs queued for later execution

     atrun [-l load_avg] [-d]

     Atrun runs jobs queued by at(1).  Root's crontab(5) must contain the

     */10     *       *       *       *       root    /usr/libexec/atrun

     so that atrun(8) gets called every ten minutes.

     At every invocation, every job in lowercase queues whose starting time
     has passed is started.  A maximum of one batch job (denoted by uppercase
     queues) is started each time atrun is invoked.

     -l load_avg
             Specifies a limiting load factor, over which batch jobs should
             not be run, instead of the compiled-in value of 1.5.

     -d      Debug; print error messages to standard error instead of using

     For atrun to work, you have to start up a cron(8) daemon.

     /var/at/spool  Directory containing output spool files
     /var/at/jobs   Directory containing job files

     cron(8),  crontab(1),  crontab(5),  at(1),  syslog(3).

     The functionality of atrun should be merged into cron(8).
