SYNOPSIS

atrun [-l load_avg] [-d]

DESCRIPTION

Atrun runs jobs queued by at(1).

Root’s crontab(5) file /etc/crontab has to contain the line
*/5* * * * root /usr/libexec/atrun

so that atrun gets invoked every five minutes.

At every invocation, atrun will start all the jobs in the lowercase queues whose start time has elapsed. In addition, if the load average over the last minute was less than the specified limit then a maximum of one batch job (denoted by the uppercase queues) is started.

OPTIONS

-l load_avg
Specify a limiting load factor, over which batch jobs should not be run, instead of the compiled in default of 1.5.
-d Debug; print error messages to standard error instead of using syslog(3).

WARNINGS

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

FILES

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