Garry Bargsley is a wild card:
Last week, we learned that quotes are not created equal. This week, we’re going deeper into the building blocks that make PowerShell scripts actually useful: variables.
If quotes are your lightsaber, variables are the Force itself. They carry information from one part of your script to another. They make the difference between a script that works on one server and a script that works on all of them. Get comfortable with variables, and you’ll look back at your pre-PowerShell DBA life the way Luke looked back at Tatooine – relieved to be moving on.
I can tell when Garry wrote this one.
