In a terminal (or xterm, or emacs) window, the command: open dirname (where dirname is . or /tmp or /home/fred) doesn't open the the specified directory in Finder. However:
- Opening a non-directory file works fine, for all sorts of file types.
- "open dirname" used to work. Alas I can't identify what had changed, but AFAIR there was no OS upgrade or bash upgrade.
- It doesn't work as root or as normal user.
