By: Chris Dent

Overview of this book

PowerShell scripts offer a handy way to automate various chores, however working effectively with these scripts can be a difficult task. This comprehensive guide starts with the fundamentals before moving on to advanced-level topics to help you become a PowerShell Core 6.0 expert. The first module, PowerShell Core 6.0 Fundamentals, begins with the new features of PowerShell Core 6.0, installing it on Linux, and working with parameters, objects and .NET classes from within PowerShell Core 6.0. As you make your way through the chapters, you'll see how to efficiently manage large amounts of data and interact with other services using PowerShell Core 6.0. You'll be able to make the most of PowerShell Core 6.0's powerful automation feature, where you will have different methods available to parse data and manipulate regular expressions and Windows Management Instrumentation (WMI). After having explored automation, you will enter the extending PowerShell Core 6.0 module, covering asynchronous processing and desired state configuration. In the last module, you will learn to extend PowerShell Core 6.0 using advanced scripts and filters, and also debug issues along with working on error handling techniques. By the end of this book, you will be an expert in scripting with PowerShell Core 6.0.

Summary

In this chapter, we briefly explored the job commands built into PowerShell; since they are built in, they are a solid starting point for running asynchronous operations.

Event subscribers are used to reacting to events, or things of interest, that happen. The event commands are used to work with events on .NET objects.

Finally, we looked at how Runspaces and Runspace pools can be used in PowerShell as an efficient method of working asynchronously.

In the next chapter, we will explore the building blocks of larger scripts.
