Hi I have a powershell script that uses some variables, and they get passed to different functions etc. When I run the script multiple times I notice some of the variables have values from previous run? Is there a way to clear all variables before I start the run each time?
Thanks

Hello,
Which tool are you using? E.g. in PowerShell you can do this with menu "Debug" => "Reset runspace".
Anyway, you should initialize your variable with a proper value, then you don't have this problem.

I would say, it depends on the data type; objects with $null, numeric e.g. with 0, string with [String]::Empty and so on.
