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).
