Sorry, I get different errors: The first way yields:
displayname: The term ‘displayname’ is not recognized as a name of a cmdlet, function, script file, or executable program.
The other way: Invalid filter clause
This script works fine!
clsforeach ($own in import-csv -path c:\Users\580616\DistinctOwners.csv) {(echo “$own.owner”)}
When you crosspost the same question at the same time to different forums you should at least post links to the other forums along with your question to avoid people willing to help you potentially wasting their time.
