PowerShell 101
PowerShell 101
The No-Nonsense Guide to Windows PowerShell
About the Book
Before PowerShell, I began my career as an IT Pro, pointing and clicking in the GUI. I wrote this book to save IT Pros from themselves by reducing the learning curve and helping them avoid being reluctant to learn PowerShell.
Instead of a book that covers topics with fictitious scenarios, this book is a condensed version targeting the specific topics I've found an IT Pro needs to know to succeed with PowerShell in a real-world production environment. It's a collection of what I wish someone would have told me when I started learning PowerShell, along with the tips, tricks, and best practices that I've learned while using PowerShell since 2007.
This book focuses on Windows PowerShell version 5.1 running on Windows 11 and Windows Server 2022 in a Microsoft Active Directory domain environment. However, the basic concepts apply to all versions of PowerShell running on any supported platform.
All (100%) of the royalties from the sales of this book beginning June 3rd, 2020, and later are donated to the OnRamp scholarship program to help bootstrap others into the industry.
