Noob Question - - How to call InvocationInfo.PSScriptRoot for a PowerShell Module

Question

I am teaching myself C# by building a PowerShell module. I want to retrieve the PSScriptRoot property from the InvocationInfo class but it appears to be something that is called indirectly. Does anyone have guidance on a) how to invoke it or b) how to use it to spit out the script root?

Answer 1

You can use the automatic variable $PSScriptRoot anytime a script is running.
If you want to see the output, just

Write-Host $PSScriptRoot

Or $MyInvocation.PSScriptRoot , that will have information about the calling script and not the current script

Additional information about all the automatic variables is available on Learn:
