Pass custom Parameters for & call

Question

In Powershell I am calling a custom script:

 &  C:\test.ps1

I want to pass a custom parameter to that script. I am trying ArgumentList. But I think that only deals with predefined arguments.

 &  C:\test.ps1 -ArgumentList "Something"

I'm not sure how to pass my own custom variable to another script that I call...

You have two options in this scenario:

& C:\Test.ps1 -Switch1 -arg 'this is an arg'

Or the Start-Process cmdlet:

Start-Process -FilePath 'C:\Test.ps1' -ArgumentList @('-Switch1','-arg','this is an arg')

But this begs the question: why are you invoking a PowerShell script instead of modularizing it to a function or module to import to the script you intend to use it?

How would I call that inside the Test.ps1 script. Would it be $Switch1? – It's Just a Printer Driver Sep 18 '17 at 15:43
@TakafuKeyomama Could you clarify what you want to do? – Maximilian Burszley Sep 18 '17 at 15:43
@TakafuKeyomama In the first example you need to [declare the parameters](https://learn.microsoft.com/en-us/powershell/module/microsoft.powershell.core/about/about_functions_advanced_parameters) in `Test.ps1`. For the second, you can access them through `$args` – Mathias R. Jessen Sep 18 '17 at 16:02
