NAME
       atd - run jobs queued for later execution

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

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      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).

       -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.

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).
