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) must contain the line: */10 * * * * root /usr/libexec/atrun so that atrun(8) gets called every ten minutes. At every invocation, every job in lowercase queues whose starting time has passed is started. A maximum of one batch job (denoted by upper- case queues) is started each time atrun is invoked. OPTIONS
-l load_avg Specifies a limiting load factor, over which batch jobs should not be run, instead of the compiled-in value 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 SEE ALSO
at(1), crontab(1), syslog(3), crontab(5), cron(8) AUTHORS
Thomas Koenig <ig25@rz.uni-karlsruhe.de> BUGS
The functionality of atrun should be merged into cron(8). BSD

NAME
atd - run jobs queued for later execution SYNOPSIS
atd [-l load_avg] [-b batch_interval] [-d] [-f] [-s] DESCRIPTION
atd runs jobs queued by at(1). OPTIONS
-l Specifies a limiting load factor, over which batch jobs should not be run, instead of the compile-time choice of 0.8. For an SMP system with n CPUs, you will probably want to set this higher than n-1. -b Specify the minimum interval in seconds between the start of two batch jobs (60 default). -d Debug; print error messages to standard error instead of using syslog(3). This option also implies -f. -f Run atd in the foreground. -s Process the at/batch queue only once. This is primarily of use for compatibility with old versions of at; atd -s is equivalent to the old atrun command. WARNING
atd won't work if its spool directory is mounted via NFS even if no_root_squash is set. FILES
/var/spool/at The directory for storing jobs; this should be mode 700, owner root. /var/spool/at/spool The directory for storing output; this should be mode 700, owner root. /etc/at.allow, /etc/at.deny determine who can use the at system. SEE ALSO
at(1), at.deny(5), at.allow(5), cron(8), crontab(1), syslog(3). BUGS
The functionality of atd should be merged into cron(8). 2009-11-14 ATD(8)
