This book covers a lot about Linux and has some great information to help someone study for the Linux+ exam. As others have noticed, I too have found a few typos. The book clearly wants to cover a lot of critical information about Linux and the exam, so certain sections are definitely lighter than others. I have not viewed the included CD yet, so cannot comment on its quality. If someone is looking to learn about Linux and is looking for a study guide for the Linux+ exam, this is a good start. I would caution readers who are also looking to use this book as a Linux reference book.

Bought this book because it had a high content (1000+ pgs), practice exams, and a test CD. Halfway through the book and I am already purchasing another Linux+ study guide because this one is flawed. Several practice exam questions do not match the given answers, there are *many* typos, alot of focus on general knowledge and not enough in depth review on probable exam topics per chapter.

I went with this book because it was the latest Linux+ study guide published, however I am going to purchase the Linux+ Study guide from Sybex as I had previously with my A+/Network+/Inet+ exams.

Do not let the large volume of this book fool you, alot of it is composed of basic knowledge which prepares you for the exam content. This book seems to be more orientated to the Beginner level user, one who has never touched Linux. If you are a intermediate-experienced Linux user, this book is not for you. If you are a beginner, I would definitely recommend getting a supplementary study guide to this book.

I've gone through 3 chapters of this book, and will be switching to a different one. There are enough errors both in the text and in the practice questions that I find it hard to trust what I read.

Robb Tracy does an excellent -- and up-to-date -- job of covering lots of Linux real estate. Whether you're a beginner or someone with experience, this book is worth the money. Between its extensive exercises, lab tests, drills, and self-tests, you will know this subject! Tracy also makes each chapter digestible, i.e., there are no endless chapters that wander. Those who failed their tests did so because they made the rookie mistake of relying on one resource. Jeez, read a second book dudes!

The book is very good and I like the postage packaging. Delivery was quick I appreciate it very much. I have no problem with the item.

That's good business.

This book is a fairly good introduction to the principles of Linux system administration. Someone with little or no Linux experience should be able to use this book and learn quite a lot on the subject. There are numerous examples, and the practical labs included are good as well.

However, here are two serious caveats:

1. This book did not prepare me adequately for the actual CompTIA Linux+ certification exam. When I took the exam, I found questions on the exam covering concepts that were either not covered in this book, or were covered very briefly. The test is much more detailed and in-depth than this book goes, so I do not recommend that someone taking the Linux+ test rely solely on this book as a study aid for the test.

2. The book is filled with errors. They are mainly typographical errors, but there are a few errors where the author has simply misstated some of the information. I sent a 3-page errata sheet to the publisher. Hopefully they will publish an errata page for this book -- if so, it will be on the following Web page: http://www.mhprofessional.com/?page=/mhp/categories/computing/content/errata.html. You should check the site from time to time to see if they have published an errata sheet for this volume. Absent the errata sheet, keep your eyes open for numerous errors (file names spelled wrong, commands misprinted, etc.), especially in the self-test sections.

Overall, it is a book worth reading to learn about Linux, but due to the errors and due to the fact that it does not adequately meet its stated purpose as a Linux+ certification test prep guide, I gave it only 3 stars.

I bought this book, expecting that it would teach me for the cert. It does more that that. It teaches me the essentials of linux and things that you might have learnt over experience. Event small pieces of skills put together forms a mountain. In the same way, the author has put things together in such a way that you would not have your heart filled with a feeling that you learnt for yet another certification exam, but you would have the real feeling of learning and playing with linux. The thing about knowledge and skills is to go to the foundational level, the higher your knowledge level the deeper you go into foundations. This book will help you do that in linux and if you feel that this review is bad, please feel free to contact me at shyaam (at) gmail (dot) com.

I usually buy Sybex books, but they didn't have one when I bought this. My mistake, and today it cost me the price of this book plus the $230 exam fee. Ugh. I knew while I was reading it that it wasn't very well written, and told my peers the same. Still, I thought the material would be close enough for me to pass (it wasn't). Bad omen - check out the wording and answer on the very first self-study test question at the end of the very first chapter. I found many spots in the book that were just not accurate.

This book includes a CD with practice study questions too, and an offer to download more from the web. I did, and used all of them to study. After all that, I was sure that I knew the material well enough to at least pass. I'm a 4-yr college grad, work as a SysAdmin (including Linux), I'm a good test-taker, and have passed my MCSE and Network+ exams. Nope - I could tell as I took the test that I was not prepared, and I'm just sick about it (I hate to fail).

Robb Tracy, if you read this, you should send me a refund. I'm either going to go for the LPI certification, or switch to the Sybex book to continue study for Linux+.

The book is very well written. Bravo! Makes complex topics look simple. Clarity is genius. I thought DNS, DHCP and NIS was going to be tough to describe in a job interview. Whew.. luckily I read this book and nailed it. I'm not even sure which chapters sticks out the best because they're all written and laid out nicely. The boot process was written better than any that I've read. Broke it down into 3 phases with a nice flow diagram. RAID was explained so simply I wonder why other books didn't describe it like this. Sudo section.. light bulb turned on. Love this book!
