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
-lload_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

BUGS
The functionality of atrun should be
merged into cron(8).
