106Part I:Getting Your Feet Wet If you ve been using computers for many years, you may also be familiar with the command-line interface, which usually consists of a black screenwith white text. The initial release and early development of Linux was allcommand-line-oriented; GUIs then grew as the icing on the Linux cake, making it a lot more colorful to use and easier for people who would rather point and click than type. In choosing between the command-line and the GUI, you need to consider anumber of factors. For a lot of people, this decision is pretty much a no-brainerissue. They have no intention of leaving GUIs behind. That s fine, but at thevery least, you may want to become familiar with what s under the hood. Someday, your GUI might break and leave you at the ever-dreaded login prompt! Deciding Which Interface to UseOne important factor when choosing between the command-line interfaceand a GUI is speed. Keep in mind that if you re a programmer who needs tocompile programs or a scientist who needs to run software that does heavynumber crunching, the GUI slows down your system. You also need to typi- cally shut off the GUI when using Linux as a server, because it s mostly awaste of RAM and processing speed more often than not, a server justdoes its thing with no one sitting there watching over it. Readability can also be a big issue when choosing between the GUI and the command prompt. If you have a hard time reading text in those smallcommand-prompt windows from within the GUI (Chapters 14 and 20 covervarious ways to switch around), you can either make the windows and thefont bigger, or work directly with the command prompt outside of the GUI. However, on a desktop that you want to use for word-processing or editingimages, you ll want a point-and-click environment. This setup is the type Ifocus on, but I don t leave you without any clue about the command-line, just in case! You also can choose from two major GUI versions: GNOME and KDE. Somepeople prefer one, and some the other, and I m not here to tell you which touse. If you stuck with the defaults for your distribution, then you re using Fedora:GNOME Knoppix:KDE Linspire:KDE Mandrake:KDE SuSE:KDE Xandros:KDE10_
