👈 Exercises | TOC | Chapter 3 Working with Files in Go 👉

In this chapter, you explored a few ways to get input from your users. You used command-line arguments, environment variables, and standard input. More importantly, you got more comfortable producing your own command-line tools by using common standards and practices.

In the next chapter, you’ll build on these concepts by handling files, thus enabling you to create even more powerful and useful tools.
