After the initial exploration in Chapter 2, we are ready to discuss the files and directories on a Linux system in more detail. Many users have difficulties with Linux because they lack an overview of what kind of data is kept in which locations. We will try to shine some light on the organization of files in the file system.
We will also list the most important files and directories and use different methods of viewing the content of those files, and learn how files and directories can be created, moved and deleted.
After completion of the exercises in this chapter, you will be able to:
Describe the layout of a Linux file system
Display and set paths
Describe the most important files, including kernel and shell
Find lost and hidden files
Create, move and delete files and directories
