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).

     The system	crontab(5) file	/etc/crontab must contain the line

     */5     *	     *	     *	     *	     root    /usr/libexec/atrun

     so	atrun is invoked every five minutes.

     At	every invocation, atrun	starts 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 checks the status of its owner's account
     with pam(3) and refuses 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,	a cron(8) daemon must be running atrun periodically.

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).
