Chapter 5. Redirection, Pipe and Shell Scripts

Redirection is used for changing standard input, standard output or standard error, whose default settings are keyboard or terminal display. For example, with redirection, you can use a text file as an input or an output medium for commands.
Pipe is used for combining multiple commands.
A shell script is a text file that contains a sequence of commands. Using the shell script, you can run multiple commands as one operation without human intervention during the process.
In this chapter, you will learn these essential concepts in Linux operation along with some data-handling commands.
