atrun - run jobs queued for later execution

 

NAME

      atrun - run jobs queued for later execution
 

SYNOPSIS

      atrun [-l load_avg] [-d]
 

DESCRIPTION

      Atrun runs jobs queued by at(1).
 
      Root’s crontab(5) file /etc/crontab has to contain the line
 
      */5     *       *       *       *       root    /usr/libexec/atrun
 
      so that atrun(8) gets invoked every five minutes.
 
      At every invocation, atrun will start all the jobs in the lowercase
      queues whose start time has elapsed.  In addition, if the load average
      over the last minute was less than the specified limit then a maximum of
      one batch job (denoted by the uppercase queues) is started.
 

OPTIONS

      -l load_avg
              Specify a limiting load factor, over which batch jobs should not
              be run, instead of the compiled in default of 1.5.
 
      -d      Debug; print error messages to standard error instead of using
              syslog(3).
 

WARNINGS

      For atrun to work, you have to start up a cron(8) daemon.
 

FILES

      /var/at/spool  Directory containing output spool files
      /var/at/jobs   Directory containing job files
      at(1), crontab(1), syslog(3), crontab(5), cron(8)
 

BUGS

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