atrun

atrun

atrun Runs jobs queued by at.
	
atrun [-l <load_avg>] [d]

atrun runs commands queued by at. root's crontab (/etc/crontab) must contain this line:
*/10 * * * * root /usr/libexec/atrun

so that atrun is called every 10 minutes. By default, the atrun line is disabled to prevent disk access every 10 minutes. Enable the atrun line in order to use at.
At every invocation, every job whose start time has passed is started. A maximum of one batch job is started.
For atrun to work, a cron daemon must also be running.
-l <load_avg> Specifies a limiting load average, over which batch runs should not be run, instead of the default value of 1.5.
-d Debug mode. Prints error messages to standard error instead of using syslog.
