Okay, if I do a (dir *.dll).count in a folder (say system32). I get the number of dll files in that folder. But if I do a (dir *.dll) | gm
Well, I don't see count listed in the output. So where does it come from, and what other ones are there?
(add: Never mind, I found it in the about_properties file, under PROPERTIES OF SCALAR OBJECTS AND COLLECTIONS.)
The commands produce a collection of objects. Get-Member normally shows you the members of what's _inside_ the collection, rather than the collection itself, which is where the Count property comes from.
