How do you unistall a program ?
Is it cool to go through and just delete it from all the directories or is there a better mehthod?

If you used a package to install it, such as apt-get or rpm, then you can use the packaging tools to uninstall it. If you compiled the program from source, then you must go through and delete the directories and binaries of the program. What distribution are you using, and how did you install the program you want to delete?

I am using RH7 and used the rpm .I tried to install a program (portsentry) and couldn't get it to work.So i tried to manually uninstall everything.I have since found the tutorial on this site and it will not let me install it again.Says it is already installed and won't overwrite.
