The dollar sign represents the terminal prompt. It’s there to tell you that you should type the code in your terminal, but you should just type whatever comes after the dollar sign, without the dollar sign itself.

If you read the electronic version of the book, clicking the file name above the code lets you see the full source for that file on the Pragmatic Bookshelf web site.
