for everyone writing scripts, java programs, etc, to parse
condor_status or condor_q output, you should *always* invoke
these tools using "-format" options.
a) you can get condor_status or condor_q to give you whatever
information you want in whatever format is easiest for you to parse.
b) the attributes that are sometimes chopped short to fit on a single
80 column screen (like the resource name in condor_status) can be
printed out in full.
and most importantly:
c) you *never* have to worry about us changing the formatting of the
default output and breaking your script, since -format will always
work and will always print out whatever you told it to print.
for more details, see the condor_q command reference page:
(-format also works with condor_status, it's just that the condor_q
reference page has more details and some examples).
