This edition of the All in One can be used for certification prep on the newest exam. We just use it to study Linux, and to aid in using Linux on laptops with an Ubuntu CD, or by creating Ubuntu flash drives to boot students Windows laptops into Linux.
I find the book to be surprisingly readable, given that it has an exam-prep aspect. Command line and GUI, primary emphasis on command line.
The book offers fairly comprehensive coverage of important Linux concepts, commands, and files. The included VMs and eBook are a nice touch. I could even see myself using this as a real-life reference, provided I was in somehow in a situation where I had access to the book, but not the man pages or Google. In any case, close study of the book will increase your practical Linux knowledge.
The exam isn't practical (nor do I think it's intended to be). It's pedantic as all get out. There are hundreds of great Linux administration books out there (and even better support in the online community), but one doesn't buy this book as an admin guide. You buy it to prepare for the CompTIA Linux+ exam. The book falls short.
I've taken industry exams previously (IT and finance), and the material in this book was further divorced from the real exam than anything I've sat for previously. About 20% of the questions I saw on the exam were not addressed in the book whatsoever (e.g. 'noclobber,' 'batch'). About the same number were covered in a totally different syntax than what the exam tested (e.g. chown and creating bash functions). In fairness, the author cautions that no one knows for sure what CompTIA will put on the test, but I found better analogs to the real test for free online (not in sufficient quantities, mind you). With this in mind, I have a hard time believing that CompTIA is such a bastion of secrecy that the author, who holds this certification himself, can't get any closer to the real thing (with apologies to Mr. Tracy if that's the case).
This edition contains editorial oversights that could negatively impact study: it confuses the 'type' and 'file' commands in the Chapter 4 review, the chapter 12 review says “epmod” instead of “depmod,” and one of the exam tips references the LILO bootloader as something you need to study, likely left over from the first edition (LILO has been removed from the 103/4 exams).
The author demonstrates an over-reliance on OpenSUSE specific examples; for example, Chapter 9's section on group membership includes options that only work on (older!) versions of OpenSUSE... they don't even work on the included OpenSUSE VM. The book doesn't disclaim this. Conversely, Debian-like distributions are treated as an afterthought. So of course, the test included 3-4 Debian specific questions and 0 on OpenSUSE.
Heavy focus is given to configuration file directives; again, good to know in practice but disproportionately represented compared to the test (I think 2 questions dealt with config directives).
Finally, there's some sloppy oversight on the included test prep software: e.g. “choose two” questions that only let you select one answer, a reference to gedit that's supposed to say gdisk, and most seriously, about 5 questions where -i and -l are impossible to tell apart due to font choices.
I feel it bears repeating that I generally do not believe in “teaching to the test,” and value practical applications of learned concepts. But, the book's intended audience is IT professionals hoping to get a specific certification, and dropping money up front to do it. With that in mind, I expect better.
To end on some hopefully constructive advice to others seeking this Cert:
- start by reading the CompTIA objectives (all 150-ish of them)... I foolishly put that off till near the end. Prioritize your study accordingly.
- set up either an OpenSUSE or CentOS machine AND a Debian/Ubuntu machine, and take it upon yourself to learn the differences between them, especially in /etc and environment variables.
- Having not purchased any other books for this exam, I can't recommend an alternative, but I would start by using the “Look Inside” feature to compare other books' chapter review questions to the (limited) preview questions on CompTIA's (and other) sites; hopefully that will point you in a better direction.
The best advice I could give is to look at his exam excercises, but to have an image of Ubuntu running along side. Translate his OpenSuse examples into the Ubuntu system . I also noticed his snapshots are missing a few of them, and some are improperly configured, or the steps he gives have incorrect syntax. Buyer beware.
For one you have to "Run snapshots 6-1 for the correctly configured environment" Problem is the snapshots aren't named 6-1 or anything similar. And they also don't work when you try to restore the snapshots. So basically the exercises/examples in the book are pretty much worthless to try w/ the VM included.
For those wondering, I am not new to virtual software vmware/virtualbox or to snapshots. Theses just don't work. The VM wouldn't work in VMware, which I expected. But only the VM loads in virtualbox, there isn't going to be any restoring snapshots. The author missed the mark w/ the VM. Should of just made an .ova which would work, and not include all the silly snapshot stuff he attempted.
I'm going with another study guide, as I don't have time to trouble shoot the author's VM fail.
Attached is a picture of what the snapshots are named. I tried extracting the zip w/ different tools and still the same naming scheme, and still no loading of snapshots.
To top it off all the software included is for Windows (.exe)
UPDATE: This book keeps getting worse and worse. If I could give 0 stars, that is what this book would be entitled to.
I'd be willing to bet that all of the 5 start reviews, either didn't read the book, or totally failed their exam if they relied on this book alone to pass.
There were so many errors/typos I couldn't even keep count. The bad part is that the errors would appear multiple times throughout the book (as if the author copy/pasted the errors made), and the correct version of the error only would appear once. It would totally contradict itself through the book.
Also this book is focused on the older exam course ware. For example, there is "init" and "systemd" , with "init" being legacy and barely found now days, and "systemd" being the current. Can you guess which of the 2 the book focuses on? If you picked the older (almost never found) "init" you'd be correct.
And it doesn't stop there. The author does it with everything throughout the book. For instance, grub and grub2. The author heavily focuses on grub (legacy) and glazes right over grub2 (currently dominant).
This book focuses on all things init, and leaves systemd as an exercise for the reader to figure out or research themselves. When systemd is the focus on the current Linux+ exam. It just doesn't make any sense.
The author is clearly a legacy linux software guy. Any situation in the book where there would be a choice of old and outdated Vs new and current, the author choose to only focus on the old and outdated, and barely even mention the new and current.
Linux+ books are clearly lacking in editing and current material.
Your only chance with this book is if you take the LX0-101 and LX0-102, which are both no longer available. Because they are no longer prevalent.
