Overview of this book

PowerShell scripts offer a handy way to automate various chores. Working with these scripts effectively can be a difficult task. This comprehensive guide starts from scratch and covers advanced-level topics to make you a PowerShell expert. The first module, PowerShell Fundamentals, begins with new features, installing PowerShell on Linux, working with parameters and objects, and also how you can work with .NET classes from within PowerShell. In the next module, you’ll see how to efficiently manage large amounts of data and interact with other services using PowerShell. You’ll be able to make the most of PowerShell’s powerful automation feature, where you will have different methods to parse and manipulate data, regular expressions, and WMI. After automation, you will enter the Extending PowerShell module, which covers topics such as asynchronous processing and, creating modules. The final step is to secure your PowerShell, so you will land in the last module, Securing and Debugging PowerShell, which covers PowerShell execution policies, error handling techniques, and testing. By the end of the book, you will be an expert in using the PowerShell language.

Preface

Classes


A class is a set of instructions that dictate how a specific instance of an object is to be created. A class is, in a sense, a recipe.

In the case of this book, a class includes details of authoring, editorial processes, and publication steps. These steps are, hopefully, invisible to anyone reading this book; they are part of the internal implementation of the class. Following these steps will produce an instance of the PowerShellBook object.

It is often necessary to look up the instructions for using a class in the .NET class library on MSDN:

The starting point for creating an instance of an object is often what is known as a Constructor.
