Chapter 4Working with Files and Directories

You probably spend a lot of your time working with files and directories. You write programs, change configuration files, copy and move files around your projects, rename files, and maybe even back things up.

In the last chapter, you learned how to use the CLI to move around the filesystem. In this chapter, you’ll manipulate that filesystem. You’ll concatenate files, read larger files, and manage permissions. You’ll move, rename, and copy files and directories, all without ever using a graphical tool.
