PowerShell is part of nearly everything a Windows administrator touches, and the version 3 adds even more powerful features.
With PowerShell, almost every aspect of Windows systems and servers can be securely and efficiently automated. Designed to provide the knowhow needed to master PowerShell, this book goes beyond the basics and offers the deep knowledge and insight needed to tackle any task. »PowerShell in Depth« is a book that will be used again and again. Each of the 40 chapters is short, concise, to-the-point, and focused on a specific area of PowerShell. Written by three seasoned PowerShell experts, every technique has been thoroughly tested. With this book in hand, readers will save hours of time and effort while consistently and quickly creating production-quality, maintainable scripts.
This book was written as a reference for system administrators. You can read the book cover to cover, and we’ve tried to arrange the chapters in a logical progression, but, in the end, it works best as a reference, where you can explore a topic more deeply in the chapter that is devoted to a particular subject. Chapter 1 will tell you more about what you will learn in the book, and what you need to know before you start.
The 40 chapters in the book are arranged into four parts, as follows:
- Part 1 “Fundamentals” includes chapters 1 through 9 which cover the basics associated with using PowerShell. Although we didn’t write this book as a tutorial, there are a few basics you’ll need to explore before you can use PowerShell effectively: the pipeline, the concept of PowerShell hosts, the shell’s help system, and so forth. We’ll dive deeper into some of these topics than a tutorial normally would, so even if you’re already familiar with these foundational concepts, it’s worth a quick read-through of these chapters.
- Part 2 “PowerShell management” covers topics such as remote control, background jobs, regular expressions, and HTML and XML. These are just a few of the core technologies accessible within PowerShell that make server and client management easier, more scalable, and more effective. Chapters 10 through 18 tackle these technologies individually, and we dive as deeply as we can into them, so that you can master their intricacies and subtleties.
- Part 3 “PowerShell Scripting and Automation” includes chapters 19 through 33 which have a single goal: repeatability. Using PowerShell’s scripting language, along with associated technologies like workflow, you can begin to create reusable tools that automate key tasks and processes in your environment.
- Part 4 “Advanced PowerShell” consists of chapters 34 through 40. One of PowerShell’s greatest strengths is its ability to connect to other technologies, such as WMI, CIM, COM, .NET, and a host of other acronyms. The chapters in part 4 look at each of these and demonstrate how PowerShell can utilize them. We give you a starting place for doing this, and then we provide you with some direction for further independent exploration.
