hi Everyone,
I have been through this a million times, but I never seem to remember, and have a hard time finding the answer online or in my archives.

On a Linux system, how should I set org-file-apps to allow org to open odt files in libreoffice, html files in Firefox, and pdf files in evince (especially in export-and-open commands)?

I have tried a couple of htings; this is what C-h v org-file-apps currently says:

Its value is ((remote . emacs) (system . mailcap) (t . mailcap))
Original value was
((auto-mode . emacs)
 ("\\.mm\\'" . default)
 ("\\.x?html?\\'" . default)
 ("\\.pdf\\'" . default))

There's no /etc/mailcap on my mahcine (?), and .mailcap reads:

*/*; xdg-open "%s"


Running `xdg-open file.odt` from a terminal will open the file in libreoffice, but exporting to odt and opening with C-c C-e o O opens the file in emacs.  What should I try next? Thank you!
