Chapter 3: Getting to Know Red Hat Linux This chapter presents a view of Red Hat Linux from the shell. The shell is a command-line interpreter that lets you access some of the most critical Red Hat Linux tools. The shell is powerful, complex, and almost completely unintuitive. Although, at first, it isn t obvious how to use the shell, with the right help you can quickly learn many of the most important shell features. This chapter is your guide to logging in and working with the Linux system commands, processes, and file system from the shell. After describing the simple process of logging in to Red Hat Linux, this chapter describes the shell environment and helps you tailor it to your needs. It also describes how to use and move around the file system. Logging in to Red Hat Linux Because Red Hat Linux was created as a multiuser computer system, even if you are the only person using the computer, you start by logging in. Logging in identifies you as a particular user. With that identity, Red Hat Linux can start up your configuration and give you appropriate permissions to files and programs. After the computer has been turned on and the operating system has started, you see either a graphical login screen (default) or a text-based login prompt. The text-based prompt should look similar to this: Red Hat Linux release 7.2 Kernel 2.4.7-2 on an i686 localhost login: The graphical login is typically your entry into the X Window System graphical user interface (GUI). Figure 3-1 is an example of the login window you see if you are using the Gnome desktop environment. Figure 3-1: A graphical login can access the Red Hat Linux GUI. Notice the several menu buttons on the login screen. You can ignore them and simply log in. Or you can use these buttons as follows: Session Usually when you log in, your graphical desktop starts up (either Gnome or KDE desktops). Click Session to choose a different desktop (if available) or to select Failsafe. If you can’t remember which desktop to use, you can choose Last (to use the desktop you used most recently) or Default (to use the desktop set as your default). You use Failsafe if you want only a shell interface (the shell is described later in this chapter). Note The failsafe session is used primarily to correct problems when, for some reason, your desktop session won’t start properly. For example, graphics settings may be wrong, resulting in a garbled screen. The
