ATD(8)

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.

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

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

BUGS
       The functionality of atd should be merged into cron(1).
