NAME

atd - run jobs queued for later execution

atd [-l load_avg] [-b batch_interval] [-d] [-s] [-n]

atd runs jobs queued by at(1) .

Tag	Description
-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	Specifiy 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) .
-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.
-n	Don’t fork option.

atd won’t work if its spool directory is mounted via NFS even if no_root_squash is set.

/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.
