What does the “@” symbol do in Powershell?

PowerShell will actually treat any comma-separated list as an array:

“server1″,”server2”

So the @ is optional in those cases. However, for associative arrays, the @ is required:

@{“Key”=”Value”;”Key2″=”Value2″}

Officially, @ is the “array operator.” You can read more about it in the documentation that installed along with PowerShell, or in a book like “Windows PowerShell: TFM,” which I co-authored :). –  Don Jones
