If you use a version of Linux that comes with Yum, you are more than likely familiar with it. For those of you who aren't, it's a program that can either be ran with or without a GUI and that is made to install, remove and update packages on a system.

Installing packages is easy. First, figure out what package you want to use. Issue a list command to see what packages are available for download. But first, make sure you are root.

yum list ruby

This lists all available packages for the language ruby. I'm going to download the main package, ruby. So, now that I know what I want to download, instead of issuing a yum list command, it's going to be a yum install command.
