2.0 out of 5 stars Good information, way too many errors. November 18, 2013
Format:Paperback
I'm on Chapter 5 right now and have been performing all of the exercises.

Overall, the book is easy to understand and follow, and the information is very helpful and complete.

However, the large number of errors is inexcusable. I have found no less than 4 errors in commands executed in the exercises in the first 100 pages.

They are major, as well. I've found
- Package name written in the wrong order in a step
- Completely wrong tar switches for a step
- Saying "run man -k as password" instead of "run man -k password" or something like that
- Screenshots not matching inputted information and partition sizes during setup.

I'm sure I'll find many, many more errors as I complete this book.

With a group full of system administrators doing this training, It's so far easy to figure out these errors, especially if you have a good eye for error messages and use the book's information to learn how to read linux man pages and things like that. However, a real, true novice will be thrown off and may get frustrated, and there's no reason for these mistakes to be there.

Also, it's often unclear where the commands end. There was a command where the author was excited and was using an exclamation point in the sentence, but was doing so after a command! There needs to be better separation of commands and sentence punctuation. This will completely screw over novice users.

This book is clearly very new, and should have gone through more proofreading before publishing.

There must be many other good Linux system administration books out there, and I would recommend looking for them.

5.0 out of 5 stars Excellent Book January 11, 2014
Format:Paperback
I have just completed this book (bar the hands on labs at the end).
I used my wife's laptop to carry out the exercises in the book :)

I found the book to be excellent, taking you from complete beginnings - intro to Unix, how to get the evaluation copy of RedHat and guide you through installation.
Unix/Linux can be overwhelming to the novice with having to master the command line and learning about all the commands and then all the various switches and how to use the commands.
This book does an excellent job at dissecting Linux and the reader being able to digest each topic a byte :) at a time. Each chapter being modular and you quickly find your skills building up and confidence improving.

The book does a good job at covering a wide array of topics including high availability clustering, which was quite cool to watch services being switch to another node as you pull the plug on the active node.

Ok, the typos, command line errors and a couple exercises that don't work as is (some easily rectified), yes there are a fair number of typos, but in the main these are very easily spotted. There are a number of command line errors which can be spotted or require a quick google. I found this helps aid learning, as having to solve problems and fix bugs is part of being a sys admin. If you just did everything in the exercises and it just worked, you would probably learn less then by fixing things that didn't work. So yes some exercises did cause me a bit of pain and quite some time trying to get things to work, but in the end I learn't a lot from it and it sticks in your head more.

After the first 100 pages, given the number of typos/mistakes I had already come across, I started writing my own errata.

1.0 out of 5 stars Got to page 45 and returned it. June 16, 2014
Format:Paperback|Verified Purchase
This bulleted point made me return the book.
"First you can manage the file .bash_history (note that the name of this file starts with a dot), which stores all of the commands you have used before. Every user has such a file which is stored in the home directory of the user. If, for example, you want to delete this file for the user joyce, just remove it with the command rm /home/joyce/.bash_history. Notice that you must be at the root to do this. Since the name of the file begins with a dot, it is a hidden file, and normal users cannot see hidden files."

Let's go over what exactly is wrong with this statement for those not familiar with linux.
1. "...which stores all of the commands..." No, it stores 1000 commands by default and this amount can be changed by the user.
2. "if...you want to delete this file...you must be at the root to do this..." No, you need to BE the user root, or the user joyce, or any other user that has read/write access to that particular directory. You do not need to be at the root of the directory / to do anything to a file with a complete path.
3. "...and normal users cannot see hidden files..." Again, no. Any user can see any file in any directory they have read access to. Any user can use the command ' ls -al ' to see any and ALL hidden files.

I'm sorry, but if there are this many errors in one bullet on page 45 of this book, covering such a simple topic as "look at the files in a directory using the command line" what on EARTH else is wrong in the rest of this book!?!? Do not waste your time or money on this, unless you'd like something to prop up a table. It's a nice thick book and would do nicely under a table or chair leg.

More About the Author

I'm the author of several books, most of which are about Linux in professional environments. These include "Beginning the Linux Command Line", "Beginning Ubuntu Server Administration" and "Pro Ubuntu Server Administration". Being a Linux user since 1992, the motivation to write books came early. Much of the documentation that you'll find on line (especially in the early days of Linux) was hard to read, so I wanted to translate that information into something that's understandable. I'm like the guy between the developer and the end user. Writing books is not the only way I accomplish this goal. Apart from being an author, I'm a technical trainer as well, delivering Linux courses all over the planet. And if a customer has something interesting, I might be willing to do some consultancy projects as well. In the past few years, most of these have included Linux High Availability and Virtualization. Recently I have developed my skills in SELinux as well and I have helped customers implementing their own custom policies.

Apart from all that, I have a personal life as well. I live in the Netherlands (that's a small country in Europe in case you've never heard of it). I like to travel, and my work allows me to do that often and I like running and photography. I've ran 4 Marathons while writing this and I'm preparing for the Washington Marathon this fall.
