title: remove exited job from qstat list
body: <p>I'm working on a PBS server and when I type qstat -u username -t I get the following output:</p>
  
  <pre><code>                                                                         Req'd  Req'd   Elap
  Job ID               Username Queue    Jobname          SessID NDS   TSK Memory Time  S Time
  -------------------- -------- -------- ---------------- ------ ----- --- ------ ----- - -----
  13631484[2648].p     username long     pre_scan_pdf-264   6824     1  --    4gb 167:5 R 46:20
  13631484[2662].p     username long     pre_scan_pdf-266  28333     1  --    4gb 167:5 R 76:10
  13631506[3732].p     username short    ew_scan-3732      13625   --   --    4gb 01:29 E 00:14
  </code></pre>
  
  <p>So my problem is, that as you can see there is a job which has exited. </p>
  
  <p>I want to remove this job from the list, because I have a script running which checks if the expression "short " occurs in the qstat -u username -t output. If this occures then no jobs are submitted.</p>
  
  <p>Therefore i tried something like qdel 13631506[] to remove the exited job from the list, but that did not work.</p>
