👈 Exercises | TOC | Chapter 4 Navigating the File System 👉

In this chapter, you used several packages and functions to work with files. You opened files for reading and writing, used temporary files, worked with templates, and used the defer statement to ensure resources are cleaned up. These skills allow you to create powerful CLIs tools.

To complement these concepts, in the next chapter, you’ll work with directories and file system objects.
