In the next line of the example you will see a personal initialization file called HOME .X11defaults. .X11defaults is nothing more than a profile file that s it. You can edit your HOME . profile file by hand. We will learn how to do this in Part III File System Utilities where we will discuss editing files in Unix.

Most like to use BASH instead of sh because there are no history features and no aliases in sh which can become annoying. History is important when you do not want to retype the same command 100 times a day. With BASH simply press the up arrow on your keyboard to recall commands already used and stored in your system s memory. If you press the up arrow and all that is reported back is gibberish and unreadable commands you may be using an older shell. Your next step is to launch any applications you may want to use. When viewing the example .xinitrc file again you can see that programs such as an xterm window and xscreensaver are both launched in the background. Think about what other programs you may want to start during the boot-up of your system. Helpful suggestions for what you may want to eventually add include a window manager and perhaps your e-mail client. No matter what you decide the important thing to understand and learn here is how and where to make this change once you know how to edit files you can find things you want to launch and add them later. In our example the controlling process is the xterm window. When you close something that is designated as a controlling process doing so will close you out of your entire X Window System session. Let s look at another sample .xinitrc script bin sh xrdb HOME .Xprofile xsetroot -solid gray xclock -g 60x50-0 0 -bw 0 xterm -g 60X24 0 0 xterm -g 60x24 0-0 You can see that
