NAME
       queuedefs - Queue description file for at, batch, and cron commands

DESCRIPTION
       The  queuedefs file describes the characteristics of the queues managed
       by cron or specifies other characteristics for cron.   Each  noncomment
       line  in this file describes either one queue or a cron characteristic.
       Each uncommented line should be in one of the following formats.

       q.[njobj][nicen][nwaitw] max_jobs=mjobs log=lcode

       The fields in these lines are  as  follows:  The	 name  of  the	queue.
       Defined queues are as follows: The default queue for jobs started by at
       The default queue for jobs started by batch The default queue for  jobs
       run from a crontab file

	      Queues  d	 to  z	are also available for local use.  The maximum
	      number of jobs that can be run simultaneously in the  queue;  if
	      more  than  njob jobs are ready to run, only the first njob jobs
	      will be run.  The others will be initiated as currently  running
	      jobs  terminate.	 The  nice(1) value to give to all jobs in the
	      queue that are not run with a user ID of superuser.  The	number
	      of  seconds  to wait before rescheduling a job that was deferred
	      because more than njob jobs  were	 running  in  that  queue,  or
	      because  the  system-wide limit of jobs executing (max_jobs) has
	      been reached.  The maximum number of active jobs from all queues
	      that  may run at any one time.  The default is 25 jobs.  Logging
	      level of messages sent to a log file. The default is 4.  Defined
	      levels are as follows:

	      ────────────────────
	      level-code   level
	      ────────────────────
	      0		   None
	      1		   Low
	      2		   Medium
	      3		   High
	      4		   Full
	      ────────────────────

       Lines beginning with # are comments, and are ignored.

EXAMPLES
       The  following	file  specifies	 that the b queue, for batch jobs, can
       have up to 50 jobs running simultaneously; that those jobs will be  run
       with a nice value of 20.	 If a job cannot be run because too many other
       jobs are running, cron will wait 60 seconds before trying again to  run
       it.   All  other queues can have up to 100 jobs running simultaneously;
       they will be run with a nice value of  2.   If  a  job  cannot  be  run
       because	too  many  other  jobs	are  running cron will wait 60 seconds
       before trying again to run it.  b.50j20n60w

       The following file specifies that a total of 25	active	jobs  will  be
       allowed	by cron over all the queues at any one time, and cron will log
       all messages to the log file. The last two lines are comments that  are
       ignored.	 max_jobs=25 log=4 # This is a comment # And so is this
