I'm a noob with CentOS so I appreciate your valuable time and patience with my silly questions. Hopefully, I won't be a noob much longer :-) I'm using CentOS 4.4 and Plesk 8.1 on my Apache web server. I installed netPBM via yum: # yum install netpbm-devel.i386 # yum install netpbm-progs I saw no errors, and when I run "yum list installed" I see the packages. The problem is, my customers' programs can't find netPBM and neither can I. I've been looking for a file named "netpbm" or "netPBM" and I can't find it in /usr/bin or /usr/local/bin. I updated my "locate" database, then I ran "# locate netpbm" but still found nothing. I tried "which netpbm", "whereis netpbm", and everything I could think of but I still can't find it. I've tried restarting Apache to no avail. Can anyone tell me what's going on? What's frikken the path to netPBM? Is there something else I need to do, after running "yum install (pkg)"? Thanks again for your valuable time. Best wishes, -- David Black Oklahoma City, OK USA
