Well the if condition is not the problem I think, because when I execute it on command line I get exactly the result I was expecting. For e.g. this is one of the outputs: <tt>OK: 12 Users Online | UsersOnline=12;0;0;</tt> Where in fact there were only 12 users users using that system at that point. As far as permissions are concerned, I checked them and they all seem to be fine - owned by nagios and 755. --Turi <tt>Lynne.G.Lawrence@uscg.mil wrote on 09/09/2005 08:35:36 AM: > Perhaps your initial if statement is failing?
