The command qsub can be used to submit a PBS job. Continuing with the example script psort.pbs from the previous subsection, we can submit it for execution as follows.
cd lab/MPI/parallel-sum qsub sum.pbs
The status of a job can be checked with the qstat -a command. Using qstat -n also shows the nodes that were allocated to your job.
[amit@onyx parallel-sum]$ qstat -a

You can delete jobs with the qdel command.
The standard output and standard error streams are redirected into the files psort.pbs.oxxx and psort.pbs.exxx, where xxx is the job number assigned by PBS.
In case of an error in running the job after it has been accepted in the queue, PBS sends an email to the user.
