Book Description
Mastering PowerShell Scripting, Sixth Edition is a comprehensive guide to automating administration and building dependable scripts with PowerShell 7.6. Starting with command discovery, modules, variables, objects, and operators, it develops the practical language skills needed to turn repetitive tasks into reusable automation. You'll learn to work with structured and unstructured data, including strings, regular expressions, XML, JSON, and HTML, and explore .NET types and classes. The book also covers file systems, the Windows registry, WMI/CIM, web services, and remote management, including remoting over SSH. As your skills grow, you'll use jobs, events, runspaces, and runspace pools for asynchronous processing; create advanced functions and parameter validation; and build and publish modules. You'll also explore PowerShell classes and desired state configuration, analyze and test scripts with PSScriptAnalyzer and Pester, and diagnose failures using error handling and debugging techniques. An online chapter introduces graphical user interfaces. By the end, you'll be equipped to write more maintainable, testable, and effective PowerShell automation.
