ATD(8)                      System Manager's Manual                     ATD(8)

NAME
       atd - run jobs queued for later execution

SYNOPSIS
       atd [-l load_avg] [-b batch_interval] [-d] [-f] [-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 1.5.  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).  This option also implies -f.

       -f      Run atd in the foreground.

       -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.

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

FILES
       /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
       at(1), at.deny(5), at.allow(5), cron(8), crontab(1), syslog(3).

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