atd - run jobs queued for later execution

       The functionality of atd should be merged into cron(8).

atd runs jobs queued by at(1).

/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.

       atd - run jobs queued for later execution

-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.

at(1), at.deny(5), at.allow(5), cron(8), crontab(1), syslog(3).

atd [-lload_avg] [-bbatch_interval] [-d] [-f] [-s]

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