Commands revisited: pipes and redirection

Commands revisited: pipes and redirection

In this chapter, you will learn how to put the results of a command into a file, how to use a file as input to a command, and how to put commands together to form customized utilities. You will also learn how to join files together, how to write information onto the end of a file, and how to put commands in the background to use the computer to do more than one task at once.

Before you begin, you should know what files and directories are, and how to create a file using cat or vi.
