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

NAME
     atrun -- run jobs queued for later	execution

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.

     Before starting a job, atrun will check the status	of its owner's account
     with pam(3) and refuse to run the job if the account is unavailable,
     e.g., locked out or expired.

OPTIONS
     -l	load_avg
	     Specify a limiting	load factor, over which	batch jobs should not
	     be	run, instead of	the default of 1.5 * number of active CPUs.

     -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
     /etc/pam.d/atrun  pam.conf(5) configuration file for atrun
     /var/at/jobs      Directory containing job	files
     /var/at/spool     Directory containing output spool files

SEE ALSO
     at(1), crontab(1),	pam(3),	syslog(3), crontab(5), pam.conf(5), cron(8)

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