An Advanced Function Template (Version 2.1 -and -gt)

Version 2.1

Back in October 2017, I spoke at the Arizona PowerShell Saturday in Phoenix, Arizona. My topic, was introducing those that attended, to a Windows PowerShell Advanced Function Template. I found a flaw in it which I’ve since fixed in my 2.1 version linked below. For anyone after this template, this is the most current version. Newer versions, providing there are any will be included in this post and not in another, separate post around here. Therefore, 2.1 may not forever be the current version, but the current version will always be a part of this post.

The flaw that took us 2.1 was that all parameters and parameter values are logged. That’s a good thing, but it means that if someone supplied a password as a string, it would be logged (providing the Log parameter was used). Therefore, 2.1 looks for parameter’s with the word “password” in them, and then doesn’t include the parameter value. Instead, it would read like the below example. This isn’t fool proof, but I think it’s a helpful addition.

PS > Get-CPUCount -ComputerName server01 -Password 'test1' -MainPassword 'test2' -PasswordName 'test3' -xPasswordx 'test4' -Log ToScreen
