Hour 8. Filters and Piping

If you've ever learned a foreign language, you know that the most common approach is to start by building your vocabulary (almost always including the names of the months, for some reason), and then you learn about sentence-construction rules. The UNIX command line is a lot like a language. Now you've learned a lot of UNIX words, so it's time to learn how to put them together as sentences using file redirection, filters, and pipes.

Commands to be added to your vocabulary this hour include wc, sort, and uniq.
