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 compatibility with  old  ver­
               sions 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

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

FILES

       /var/spool/atjobs The directory  for  storing  jobs;  this
       should be mode 700, owner at.

       /var/spool/atspool  The direcotry for storing output; this
       should be mode 700, owner at.

       /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).
