Just Enough Ruby

There’s no need to save the file lib/example.rb file we created to learn
Ruby.

You can simply delete the file:

$ rm lib/example.rb

Check the Git status to make sure the file is gone:

$ git status
nothing to commit, working directory clean

We’ve cleaned up after our Ruby exercise.

From here on, we’re done with silly code examples. No more fooling
around. With the next chapter, we start building a real-world Rails
website.
