Unix has a reputation for being cryptic and difficult to learn, but it doesn't need to be that way. Think Unix takes an analogous approach to that of a grammar book. Rather than teaching individual words or phrases like most books, Think Unix teaches the set of logical structures to be learned. Myriad examples help you learn individual commands, and practice problems at the end of difficult sections help you learn the practical side of Unix. Strong attention is paid to learning how to read "man pages," the standard documentation on all Unix systems, including Linux. While most books simply tell you that man pages exist and spend some time teaching how to use the man command, none spend any significant amount of space teaching how to use the content of the man pages. Even if you are lost at the Unix command prompt, you can learn subsystems that are specific to the Unix flavor.
