There are a couple of things you can try. You can take a look at the
condor_wait command. This command blocks until all jobs in a cluster
have completed. Useful if you're scripting a post-cluster task.

If you're using Perl you can check out the Condor.pm module in
condor-6.8.x/lib/ directory. This module lets you register a callback
subroutine in your Perl script that gets called every time a job is
done. It accomplishes this goal by watching the job log file. If you
want to watch and react to the job log file in a language other than
Perl this is a good place to start learning about how to interpret all
the log messages you see in that file.

Finally you can combine the leave_in_queue=true submit setting
(http://www.cs.wisc.edu/condor/manual/v6.8/condor_submit.html#55407)
with liberal use of the condor_q command and it's -format option to
identify jobs in a cluster that are finished and act on them. To see a
list of jobs that have finished you use the JobStatus attribute
(http://www.cs.wisc.edu/condor/manual/v6.8/3_5Startd_Policy.html#18178):

condor_q -format "%d." ClusterId -f "%d " ProcId -const 'JobStatus == 4'

If you set leave_in_queue=true a completed job stays in the queue but
shows up with a status value of 4. So you can call condor_q with the
above options periodically from your watch program to get a list of jobs
that are done and when you do your post-job processing you simply call
condor_rm on the job to actually remove it from the queue so the next
time you generate the list it doesn't show up.

Hope that helps get you started.
