Think UNIX (Que-Consumer-Other) (Paperback)

by Jon Lasser (Author)

Editorial Reviews

Amazon.com 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.

Product 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.

5.0 out of 5 stars The way to teach a windows user how to "Think Unix", August 15, 2000

By A Customer

This book is a "One Horse" book, that horse being to teach UNIX to those who have used Windows or Macintosh OS's their whole life. Although I have been learning UNIX for over a year, and would like to think I know a little bit about it, it tends to be hard to remember how to tell someone else how to "do this" or "that". This book is great for that. This takes a user who knows how to use a mouse and keyboard, and knows how to navigate under a "windowed" operating system into the world of command prompts and even the X-Windows system. Don't expect this to make you a system administrator, it doesn't even touch many of the things a user doesn't need to know, but it does fulfill its purpose. If you would like to learn UNIX so you can install LINUX on your machine at home, this can be a great start. While a UNIX's are different in some way's, Jon tends to stick to common themes, and points out when a command just has a different name. If you would like to "remember" what your users don't know, this is also great for you. It's a great book to recommend for a user to learn on their own.

5.0 out of 5 stars not a life-saver, but surely a life-improver, October 23, 2000

By	Edward J. Hyer (Baltimore, Maryland USA) - See all my reviews

The reason I cannot call Mr. Lasser's book a "life-saver" is because I would not have perished from the Earth without it. Indeed, I probably would have figured almost all of the stuff in this book out, given six or seven years. But you gotta ask yourself, "at what cost?" In hair torn out (it's leaving fast enough, isn't it?), in hyperventilation (save that for the gym), in premature aging.

This book is not for Dummies. This book works best with people, as I may have indicated above, who Would Have Figured It Out by themselves. But while you may pretend to enjoy a rugged hike through the steeper parts of the learning curve, Mr. Lasser's book is like strapping on a jet-pack.

The book is conversational, sometimes funny (though it helps if you spend a lot of your time in front of computers), and extremely direct. If you are just curious about what this Unix thing might be good for, read the book slowly, learn a lot, and gain a solid foundation for becoming the captain of your computing destiny. If you have something you need to get done, read it quickly, learn-- well, a lot, and get where you're going in a hurry.

One caution: this book does expect that you will read it. It is not a ready reference, it is not designed for index-backward utilization. It is a short course in the skeletal framework of Unix, and not a hypertext instruction manual. If you are unaccustomed to reading as it was practiced before computer self-help books arrived to chaff the bookstores of our nation, you will not derive the maximum benefit from this book.

I recommend this book to (prospective) users of unix systems who take pleasure in reading, and need to learn a great deal very quickly.

4.0 out of 5 stars Where was this when I needed it?, October 24, 2000

By	Timothy Walker (Orlando, Florida USA) - See all my reviews (REAL NAME)

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.
