Learn Essential Bash Commands

Bash and shell script programming is central to using Linux, but it has many peculiar properties that are hard to understand and unfamiliar to many developers, with a lot of misleading and even risky information online.

In Chapter 3 of Bash Quick Start Guide, Tom Ryder shows you the commands essential for good Bash scripting. Bash programming, and shell script programming in general, is different from most other programming languages because it is designed to run other programs, mixing the commands it provides with commands installed on the local system. In this chapter, you'll discover how to use built-in commands, such as those for navigating the file system, as well as the essential system commands that are not actually included with bash, but almost certainly installed on your system.

You'll discover how to copy and move files; how to use grep to matchregular expression patterns against lines of input data; how to use wc to count lines, words, and bytes; and much more!
