One of the beauties of Unix is that you can be very productive with surprisingly little knowledge. Even better, each new trick you learn can shave minutes off of your day. We've arranged the chapters in this book by subject area, not by any suggested order of learning. Skip around to what interests you most or solves your current problem. If the current hack depends on information in another hack, we'll include a link for you to follow.
Furthermore, the "See Also" sections at the end of individual hacks often include references such as man fortune. These refer to the manual pages installed on your machine. If you're not familiar with these manpages, start with [Hack #89] .
