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 links to oneliners from Hugo Peeters, Alan Renouf, get-admin.com and Arne Fokkema
