PowerCLI: Oneliners

This page could be dedicated to Hugo Peeters as he's been supplying the community with very useful powershell oneliners for a while. But he's not the only supplier anymore as more links are getting added from other great powershell scripters. This page now contains oneliners from Hugo Peeters, Alan Renouf, get-admin.com and Arne Fokkema
