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 compat-
               ibility with old versions of at; atd -s is equivalent to the old atrun com-
               mand.  A script invoking atd -s is installed as /usr/sbin/atrun  for  back-
               ward 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).
