After reading this book for awhile, I decided to post my review according to the word “NICE”. Why this? Well, let’s see.N – NeatThe structure of this book is being planned and categorized in a way that I personally feel is neat. Although this book is primarily for readers who are not a beginner in PowerShell Technologies, however the book just walked you through bits and pieces the basic in PowerShell so that it caters to beginners who are also fast-learners. (Of course if you required more in-depth learning of PowerShell or if you are fresh to PowerShell, there are tons of books and learning resources out there. Do not worry! Earmark this book for reading purposes when you are ready!)The book is being structured in a way that it walks you through different aspect of PowerShell such as there is dependency. For example, you need to know Cmdlets before you goes into Functions. You will need to know Functions before going to Scripts. Then go to the next level of meddling with Pipelines and Modules. So all in all, this is a progressive learning over and over again from chapter to chapter.I – Intuitive and/or InstructionalAdding on to the “Neat” that I have elaborate above, I feel that the content and knowledge that I have received after reading this book is as if I am doing Self-Learning which reminds of me of all the Microsoft Official Curriculum that I have read through while preparing for my Active Directory exam for Window Server 2008. Lots of screenshots have been placed in the book to provide better illustration of the coding that the author was trying to demonstrate. On top of that, do not forget that as a reader, you have access to the ZIP Archive which contains the PowerShell Script and Module used for the various chapter. So it simply save you time to type the command out instead. Although I really encourage PowerShell lovers to type out the command rather than copying because, while you are typing, you can to interface with the various Cmdlets and you may hit into errors when you are selecting the wrong Cmdlets to perform the right tasks.Reviewing the error messages will definitely help in getting yourself prepared in troubleshooting more complex PowerShell scripts in future.C – CorrectWell, what do I mean by Correct? Do I meant that the content is Correct or the way the content is structured is Correct?No, what I actually meant is. The Author have used the Correct way to target at PowerShell lovers. In everything that we do, there may be more than one way to get to the endpoint but usually there is only one way to nail things down and make sure things are done in the Correct manner.Why is being Correct important? Take for example, if one adopts a different way of writing PowerShell script, then when the scripts are being shared with other Scripters. Then it will take others a lot of time in order to put themselves in the shoes of the original scripter. Sometime it will be worst where one will take some time to refined the scripts to their own style. What could be worst is that, if the timeline is short and there is already a shortage of resources that are available to perform a set of tasks then you wouldn’t want to expense out a resource time to reinvent the whole wheel.So let’s all adopt to a single lingo and automate the world.E – EducationI know all books are for learning, but there are definitely books that I have personally read and felt that I have learned nothing much. I would highly recommend this book to all levels of PowerShell lovers so that for beginners will have a taste of PowerShell and for advance players out there, you will get to perfect your skills.

This Book has to offer so much more than just troubleshooting. Author starts with a PowerShell primer and focuses on the 3 cmdlets (Get-Help, Get-Command & Get-Member ) which often many people overlook.I liked the approach from the Author on Troubleshooting process first know the best practices and follow those once you do it the troubleshooting process comes in.That's why he explains the peculiarities in PowerShell in second chapter and then the adopted PowerShell practices in the third chapter ( Filter left, Format right ).The best chapter of the book is the chapter 4 on PowerShell professionalism as the Author covers 4 most important aspects of when you are writing Production grade Scripts:1. Naming Convention2. Modularization3. Version Control4. Unit testingUnit testing examples using Pester are really good as they give you a good peek into what Pester can do for you.Chapter 5 is all about how to use PowerShell proactively to improve our scripts.Chapter 6 talks about when you deploy PowerShell scripts targeting a version, what to check so that there are no surprises.Right now in process of reading chapter 7 , till now the book has been a good read and it brushes all the good practices I have picked by following the forums and going through the Scripts of others.This Book is for you if you have already grasped basics of PowerShell and write scripts for your environment and you want your scripts to follow all the adopted best practices as that will help you later on troubleshoot them.
