atrun
—
run jobs queued for later execution
atrun
runs jobs queued by
at(1). Root's
crontab(5) must contain the
line:
*/10 * * * * /usr/libexec/atrun
so that atrun
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 uppercase
queues) is started each time atrun
is invoked.
-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).
For atrun
to work, a
cron(8) daemon needs to be
running.
- /var/at/spool
- Directory containing output spool files
- /var/at/jobs
- Directory containing job files
The functionality of atrun
should be merged into
cron(8).
