Garry Bargsley continues a series on Powershell capabilities:
Welcome back to PowerShell Strikes Back. We’re three weeks in, and the training is paying off. In Week 1, we learned that quotes are not interchangeable. In Week 2, we put variables to work – storing server names, config values, service objects, and boolean results. If you’ve been following along and running the examples in your own environment, you’re already writing better PowerShell than you were a month ago.
This week, we tackle the concept that transforms a script from a one-time operation into an actual tool: the ForEach loop.
Garry also ties in error handling, which is important during loop iteration.
