Working from a shell command-line interpreter within Red Hat Linux may not be as simple as using a GUI, but it offers many powerful and flexible features. This chapter describes how to log in to Red Hat Linux and use shell commands. Features for running commands include recalling commands from a history list, completing commands, and joining commands.
This chapter describes how shell environment variables can be used to store and recall important pieces of information. It also teaches you to modify shell configuration files to tailor the shell to suit your needs. Finally, the chapter describes how to use the Red Hat Linux file system to create files and directories, use permissions, and work with files (moving, copying, and removing them), and how to edit text files from the shell using the vi command.
