ATRUN(8)               DragonFly 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 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

     /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).
