Using the Shell
Christopher Negus · 2015
This chapter is a guide to working with the Linux system commands, processes, and filesystem from the shell. It describes the shell environment and helps you tailor it to your needs. The chapter focuses primarily on the bash shell because the Linux distributions, Fedora and Red Hat Enterprise Linux, both use the bash shell by default. There are several ways to get to a shell interface in Linux. Three of the most common are the shell prompt, Terminal window, and virtual console. The chapter shows commands are structured and how many special features, such as variables, command completion, and aliases are used. It also describes how to do command-line editing, how to complete parts of command lines, and how to recall and work with the history list. Finally, the chapter talks about features for recalling commands, completing commands, using variables, and creating aliases.
