Product Review
The many variants of the Unix operating system require use of a mode of thought that's significantly different from the one that's required by simpler operating systems.
Think Unix introduces readers to important fundamental and intermediate Unix commands and, in the process, inculcates them in the Unix way of thinking. It's a worthy goal in a world with more Linux users than ever, and author Jon Lasser accomplishes it. He's both a capable writer and a knowledgeable user of Unix shell commands. Lasser uses bash under Red Hat Linux in most examples--which usually apply equally well to other Unix variants--and makes asides about other shells and environments, as needed.
Like Unix itself, this book is highly literate, and rewards those who are willing to read through explanations of the command strings that pepper the paragraphs. The best strategy is to read this book from cover to cover, imagining that you're sitting through a seminar. You might know about some of the topics that are presented, but it's likely that something in every chapter will improve the depth of your Unix knowledge. A helpful pedagogical trick: Lasser has included practice problems here and there. A typical one: "Display the string 'Today's date is:,' followed by today's date." You should be able to solve these by reading the examples carefully, but you'll find solutions in the back of the book, in case you need them. This is a great book for Unix beginners.
--David Wall Topics covered: The Unix operating system and its peculiar way of allowing users to string commands together in powerful, flexible sequences. Commands and techniques are explored that have to do with files, processes, piping, shell commands, shell scripting, and the essentials of the X windowing system.
Book Description
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.
Reader Reviews
This is one of the finest elementary Unix primers ever written. Rather than focusing on specific flavors or specific results, this book teaches Unix at the conceptual level, giving you the skills needed to get at least a little work done on any system (like how to read man pages, how to navigate X windows, and how to use the editor of the gods, vi). Additionally, the material on shell scripting and networking was exceptional. While this book would serve well as a textbook (it is well-indexed and includes review questions), it is also a prime choice for new Linux users of the "I got it installed, now what?" variety. The only things holding back my fifth star are the minor but unfortunately frequent errors (but it is a first printing and, to the author's credit, errata is available online). All in all, a great book, certain to get better with time.
