qevent - subscribe and respond to Grid Engine events

       Needs tidying up and extending.

                                                   2012-01-09                                          qevent(1)

qevent  subscribes to "events" generated by the Grid Engine system and loops after writing its pid to the
       file qevent.pid.  It is used by the Grid Engine test suite, and otherwise can be used to wait for  a  job
       or task to finish more efficiently than running qstat in a loop.  See the example below.

       This is an example of waiting for a job which could be used if  the  -sync,  -hold_jid,  or  -hold_jid_ad
       options of qsub aren't sufficient.

           $ cat wait-for-job
           #!/bin/sh
           if [ "$2" = $JOBID ]; then
               echo Job $JOBID finished
               kill $(cat qevent.pid)
               exit 0
           fi
           $ export JOBID=`qsub -b y -terse sleep 30`
           $ qevent -trigger JB_END ./wait-for-job
           Job 122837 finished
           $

qevent.pid
              Id of the qevent process.

              end.
