I'm new to linux my self, I also have redhat 9, and I strongly recommend you to install apt for redhat. Apt is the packet-manger in debian, but it also have a version for redhat. Apt will download and configure packages for you.
After you have installed the rpm package you can:
apt-get update # this will update the package list
apt-get install <name> # this will download and install a package, and other
packages needed for it to work.
apt-cache search <string> # this will search for a package
/etc/apt/sources.list <- apt mirrors
* man apt *
(sometimes it is better to compile the packages from source, since apt packages can be very old)
grep is a very useful command, you should learn that
* man grep *
In gnome you can press alt+ctrl F1-F6 and put down the GUI if you have to. alt+ctrl F7 gets it up again.
Remember to read files named (with big letters) README and INSTALL when you compile from source, it isn't always the same way.
**** Important: As I said, I'm just a newbie. Some of this things can be all wrong. If you find any errors, don't flame me, but do tell med
Remember to try, and struggle
