Description

PowerShell has become the automation language of modern IT. It treats every value as a structured .NET object, chains commands through an object-aware pipeline, and runs identically on Windows, Linux, and macOS. For anyone working with infrastructure, cloud services, or reporting, fluency in PowerShell is now a real competitive advantage.

This book is a complete, sequential journey from your first command to publishing a module on the PowerShell Gallery. Across twelve chapters you install and tour the shell, master types, operators, and expressions, then handle data with variables, credentials, and serialization. You control flow and errors, build reusable functions with validation, and grow them into packaged modules and manifests. Later chapters cover metaprogramming, remoting, jobs, and parallel execution, then debugging, logging, and Pester testing, before a breadth tour of providers, CIM, .NET interop, classes, and Desired State Configuration.

By the end, you will write PowerShell that runs reliably, scales gracefully, and reads clearly enough for colleagues to build on, with the confidence to automate real workflows and ship professional, reusable tooling.

What you will learn
● Navigate the object pipeline that sets PowerShell apart.
● Work with types, operators, variables, and rich collections.
● Control flow, handle errors, and build reusable functions.
● Package modules, then scale with remoting and parallelism.
● Debug, log, and test automation using Pester tests.

Who this book is for
This book is for system administrators, DevOps engineers, cloud operators, and support professionals who want a coherent, guided path to PowerShell fluency. It is equally useful for developers coming from Bash, Python, or CMD who want to add reliable automation to their toolkit.
