Be a little careful how you schedule jobs with this concept, as only one job will run at a time and if another job is due and a long running job hasn't finished yet the other job will not be run. Also if the machine is restarted or you script is killed then the jobs will not be run.

Cron is still your preferred option hear, as all these sort of issues, and others we haven't thought of yet, are dealt with out of the box.

STANDARD OUTPUT

       Displaying Job Status

       If the -a, -i, -f, -r, -u, -n, -G, and -M options are not specified, the brief single-line display format is used. The following items are
       displayed on a single line, in the specified order, separated by white space:

       the job id
       the job name
       the job owner
       the cpu time used
       the job state
	   C -	Job is completed after having run E -  Job is exiting after having run.  H -  Job is held.  Q -  job is queued, eligible to run or
	   routed.  R -  job is running.  T -  job is being moved to new location.  W -  job is waiting for its execution time (-a option) to be
	   reached.  S -  job is suspended.

       the queue that the job is in

       If the -f option is specified, the multi-line display format is used. The output for each job consists of the header line: Job Id:  job
       identifier followed by one line per job attribute of the form: attribute_name = value

       If any of the options -a, -i, -r, -u, -n, -G or -M are specified, the normal single-line display format is used. The following items are
       displayed on a single line, in the specified order, separated by white space:

       the job id
       the job owner
       the queue the job is in
       the job name
       the session id (if the job is running)
       the number of nodes requested by the job
       the number of cpus or tasks requested by the job
       the amount of memory requested by the job
       either the cpu time, if specified, or wall time requested  by the job, (in hh:mm)
       the job state
       The amount of cpu time or wall time used by the job (in hh:mm)

EXIT STATUS

       On success, qstat will exit with a value of zero. On failure, qstat will exit with a value greater than zero.
