CompTIA Linux+ XK0-004 Cert Guide (Certification Guide)

I bought this book because a different book (McGraw-Hill All-In-One Linux+) I had been using was full of errors, typos and generally appeared as though It never made it through a technical review.Now, I'm just on Chapter 7 of this book and am just flabbergasted... some things are just missed altogether:example:Chapter 7 pages 171 and 172 describe the 'cp' command (used for copying files on mounted file systems) and then the 'scp' command (used for copying files to remote servers through ssh).Then on Page 173, the book discusses 'rsync' and keeps comparing it to the 'copy' command (which doesn't exist).Also, it is as though there was a first draft, edits were submitted but perhaps only partially integrated and then the published product is a hybrid between the two -- but not coherent.example: Chapter 7 page 175 (discussing 'diff' command)"...To see what is different between the two directories today, you would use:# diff -rq /etc /backup/date-etcOnly 2 in etc2: host.confFiles etc/hosts and etc2/hosts differOnly in etc2: java-11-openjdk ...... The returned output lines from the earlier diff command tell you several things about the state of the two locations. The first line says that the hosts.conf file only resides in the date-etc backup directory,..."so at some point someone decided to change the directory from 'etc2' to 'date-etc', but only in the command (not in the output).I've owned this book for a while now, and haven't had a lot of time to dedicate to it. There have been several times I've contemplated writing a review but hadn't. What really gets me is that the publisher's website only has 2 corrections listed for this book -- none of which I've encountered so far. I bet I've encountered more than 30 errors/inconsistencies so far.In fairness, had I bought this book first and then bought the McGraw-Hill book, I'd probably be writing a similar review on that one.Truthfully, I don't know which book is more of a disappointment. I wish Darril Gibson and his team (who writes CompTIA Security+ Get Certified Get Ahead: SY0-501 Study Guide) published a Linux+ book. The quality of those books are on a different level.

Comprehensive and targeted specifically for CompTIA's XK-004 exam objectives. I really haven't found any major problems except for Pearson's Test Prep software. You need the Portable Command Guide by William Rothwell in order to properly answer the questions on the test prep. I have come across a couple of errors or typos with specific Q&As and reported it but Pearson is slow in responding and updating obvious typo or error q&a content; replying back with canned "We have forwarded this to the author but it may be a while..." and I'm just thinking "You can see the typo if you actually read the Q&A I reported."

I am just getting into Linux and got this book and found it to be a little more advance then what I was needing. Had to get another book for beginners to get my base knowledge started. I will return back to this book at a later date.

Preliminary review:I have not yet taken the test, (am about 1/3 of the way through the book) so I cannot really indicate how well it is preparing me. That said, I find it a comfortable read and I appreciate the quizzes at the start and end of each chapter. Taking away form the experience is the number of errors in these said quizzes, where the answer they give you is directly contradicted in the text you are reading. this has left me with real concerns about the accuracy of the information I am being given.After I have taken (and either passed or failed) the certification exam I will follow up my review, but at the moment I will give it a mixed "3*" review.

The book goes in depth of all things linux but has more emphasis on systemd as oppose to init. Traditional way of Unix is supposed to be linux way of following the model, do one job and do it right. Systemd is more parallel which can lead to feature creep and unorganized crap. Other than that, the book is excellent resource for exam and as a resource itself.

very comprehensive. Notes key topics. and it tells you exactly what will be on exam.

Really good book. It is like most of the official cert guides. Definitely in-depth knowledge but definitely beneficial.

The information is good, its Linux. The authors' lack logic flow and left many errors in multiple places. It is an obvious lack of caring about the content of the book. This gives me low confidence in this book as I am just starting into chapter 3. Sad book, waste of money.Your money is better spent on a different Linux+ book, seriously people. I can't recommend a different one, but this one isn't it!
