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).

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 1.5. 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. A script invoking atd -s is installed as /usr/sbin/atrun for backward compatibility.
WARNING
atd won't work if its spool directory is mounted via NFS even if no_root_squash is set.
FILES
/var/spool/cron/atjobs The directory for storing jobs; this should be mode 700, owner daemon.
/var/spool/cron/atspool The directory for storing output; this should be mode 700, owner daemon.
/etc/at.allow, /etc/at.deny determine who can use the at system.
SEE ALSO at(1), atrun(1), cron(8), crontab(1), syslog(3), at.deny(5), at.allow(5).
BUGS
The functionality of atd should be merged into cron(8).

Hello,
I have a bunch of cron jobs in the crontab. For some reason mail from the cron jobs started going to /var/spool/mqueue instead of being sent.
