Q. How do I access an attribute of a variable in PowerShell using Write-Output?
A. If you have an object that you want to output a parameter from it using Write-Output it does not behave as you would expect. For example:
Write-Output "Name of VM is $VM.VMName"
This would actually output the VM object then .VMName as text. What is actually required is a subexpression and this is used as follows:
Write-Output "Name of VM is $($VM.VMName)"
Note the subexpression is performed using $(<to be evaluated>).
