NAME
       atd - run jobs queued for later execution

SYNOPSIS
       atd [-l load_avg] [-b batch_interval] [-d] [-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 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.

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

FILES
       /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.

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).
