ATD(8)                              Linux Programmer's Manual                              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 1.5.  For an SMP system with n CPUs, you will proba-
               bly 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).

       -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.  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/cron/atjobs The directory for storing jobs; this should be mode 700, owner dae-
       mon.

       /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), 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).
