Overview
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)
