PowerTip: Use PowerShell to Look Up Variable Values

Summary: Look up variable values in the caller’s scope.

 I’m writing a Windows PowerShell advanced function in a script module. How can I look up the value of
          variables set in my caller’s scope?

 Use the $PSCmdlet.GetVariableValue() method:

[CmdletBinding()]

param ( )

$variableValue = $PSCmdlet.GetVariableValue(‘variableName’)
