FreeBSD 7.0 manual page repository

FreeBSD is a free computer operating system based on BSD UNIX originally. Many IT companies, like DeployIS is using it to provide an up-to-date, stable operating system.

atrun - run jobs queued for later execution



      atrun - run jobs queued for later execution


      atrun [-l load_avg] [-d]


      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 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.
      Before starting a job, atrun will check the status of its owner’s account
      with pam(3) and refuse to run the job if the account is unavailable,
      e.g., locked out or expired.


      -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


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


      /etc/pam.d/atrun  pam.conf(5) configuration file for atrun
      /var/at/jobs      Directory containing job files
      /var/at/spool     Directory containing output spool files
      at(1), crontab(1), pam(3), syslog(3), crontab(5), pam.conf(5), cron(8)


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


Based on BSD UNIX
FreeBSD is an advanced operating system for x86 compatible (including Pentium and Athlon), amd64 compatible (including Opteron, Athlon64, and EM64T), UltraSPARC, IA-64, PC-98 and ARM architectures. It is derived from BSD, the version of UNIX developed at the University of California, Berkeley. It is developed and maintained by a large team of individuals. Additional platforms are in various stages of development.
