atrun

ATRUN(8)						    BSD 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 unavail-
     able, 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).
