ATD(8)                    (2009-11-14)                     ATD(8)

     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 pri-
                  marily 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).
