Fernando -

Our apologies.

The example given in the condor_hold man page is completely bogus.  The 
rest of the man page looks ok, however.

If you do
   "condor_hold <username>"
that means to hold all of the jobs belonging to that user.

If you do
   "condor_hold <username> -constraint <some-expression>"
that means to hold all of the jobs belonging to that user, AND all of the 
jobs matching the constraint.  So multiple "selections" on the same command 
line are ANDed together.

Another crazy thing w/ the example on the man page is the reference to the 
Activity attribute.  This is an attribute of the machine ad, not the job 
ad.  The constraint expression given to condor_hold may only refer to 
attributes in the job ad.

So to hold all jobs that are not running owned by user Mary, as a queue 
super user you could do:
   condor_hold -constraint "JobStatus!=2 && Owner==\"Mary\""

Or, if you were logged in as Mary (and Mary is not a queue super user), you 
could just do
   condor_hold -constraint "JobStatus!=2"
because Condor will not let you hold jobs you do not own....

Sorry about the documentation error, we will fix that for the next manual 
release.

regards,
Todd
