Have you ever used Linux? I don't even need to do that on Gentoo, my main system. Right click, format, choose a format type, format. Exactly the same as Windows.
Ed: from your other comment in this thread, I think you haven't. I don't think anyone has ever been required to use the command line to install things in Ubuntu (that are in the package manager which contains most things most users care about), but my memory only goes back to Dapper.
You don't even need a command line to install random packages you've downloaded. Just double-click them, the system package manager will show you what's inside and ask if you want to install it.
