File lists

[Bob Sneidar]

Hi Jacque. 

I wonder if the ls command lists folders with a trailing slash, while documents and apps do not have a trailing slash?

What I need is a list of both regular files and files that happen to be bundles, but does not include apps, system things, or user folders. In other words, a list of any file the user can double-click that would launch an app.

The .rtfd folders just contain a bunch of regular files (and no Content folder,) which makes those bundles indistinguishable from a user folder if you're just looking at file paths.
