We will describe the structure of the Linux file system and how under Linux, (almost) everything is a file. We will do this interactively, giving you the first closer look at some common Linux commands which will be used in scripting later on.

The following commands will be introduced in this chapter: pwd, cd, df, echo, type, cat, less.
