How do I set the default file association in Ubuntu Nautilus to something that is not listed in the Open With tab?

Question

There used to be an option for adding unlisted commands, but it seems to be gone in Unity. Does anyone know how to do that now?

Switching to XFCE fixed the problem... :P – Andrea Nov 02 '13 at 14:10 — Andrea, Nov 02 '13 at 14:10

one can use mimeopen -d file to use a custom application on the cli. Afterwards it will be the default application [even from the Nautilus].

$ mimeopen -d file.txt

Please choose a default application for files of type text/plain

      1) notepad  (wine-extension-txt)
      2) gedit  (gedit)
      3) GNU Emacs 23  (emacs23)
      4) Other...

use application # 4

use command: nano

Opening "useful.txt" with nano (text/plain)

There are other ways you can find here
