Macs and file/folder (UNIX) permissions

Why doesn’t the mac client filesystemobject inspector return unix permissions? like “other write” or “other execute”?

It would be awesome to ask for: other write of file "/Library/"
This works in the filesysystemobject inspectors in all of the linux and unix flavors apparently, but not mac.

Does anyone know of a way of getting unix permissions of a file on a mac in relevance? Short of creating a task/analysis combo?
