Great book, but needs updating for the newer CentOS versions
February 19, 2016
While this book is helpful in learning some Linux commands used by all distros, I found it was a bit outdated with regards to CentOS. I believe the book was geared towards a CentOS 6.5 version. This book is not helpful if you aren't running the specified version of CentOS. With CentOS version 7, many of the examples in this book are no longer valid or many warning messages are received due to the use of outdated commands.
Don't get me wrong, this is a very good book. It just will not be very helpful if you are using a newer version of CentOS. However, it is good information to know.
