Is there a way to filter Get-ACL to see only explicit permissions and ignore files that do not have explicit permissions applied to them?

The basic goal I have is to view all ACLs applied to a file except for ACEs for BUILTIN/ADMINISTRATORS as this is a permissions inherited from the top-level folders.

This is the code I'm currently using:

get-childitem \\server\share -recruse | get-acl | where {$_.accesstostring -notlike "*admin*"}

However, this does indeed block the administrators from displaying, but since administrators is in every ACL, it also blocks everything else from applying.

Any ideas?

Does Admin always show up first? If so, try:

(get-childitem \\server\share -recurse | get-acl |%{$_.accesstostring}).substring(42)
