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).
