NAME    [Toc]    [Back]

       atd - run jobs queued for later execution

SYNOPSIS    [Toc]    [Back]

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

DESCRIPTION    [Toc]    [Back]

       atd runs jobs queued by at(1).

OPTIONS    [Toc]    [Back]

       -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      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    [Toc]    [Back]

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

FILES    [Toc]    [Back]

       /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    [Toc]    [Back]

       at(1),	atrun(1),   cron(8),   crontab(1),   syslog(3),    at.deny(5),

BUGS    [Toc]    [Back]

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