I associated pdf with Okular using mimeopen. Then I became curious where it had saved the configuration. My first guess was:

$HOME/.config/mimeapps.list

but it didn't contain the right entry. So I searched:

updatedb && locate mime | xargs egrep -e "okular" 2> /dev/null

and found nothing. So which file is used mimeopen to save associations?

update

I started digging, following a clue from cas's comment, and I found a file:

$HOME/.local/share/okular-usercreated-1.desktop.

with the content:

[Desktop Entry]
Version=1.0
Encoding=UTF-8
Type=Application
Name=okular
NoDisplay=true
Exec=okular

Which strangely does not have a MimeType record

My guess: Since I use openbox, which doesn't set $DE environmental variable mimeopen had been forced to create a new .desktop file when I used it. Which is inconvenient.

I read it is possible to run openbox inside other desktop environments. I will give it a try.

  • possibly ~/.local/share/applications/mimeinfo.cache. BTW, see man pages for mimeopen,update-mime-database, and update-desktop-database. See also man pages for xdg-open and xdg-mime and related programs. The freedesktop.org people have been busy little beavers making things as confusing and complicated as possible. – cas Jul 3 '16 at 15:05

I found the records:

mimeopen when no desktop environment is specified saves the records in:

$HOME/.local/share/applications/defaults.list

  • This isn't the location that xdg-open uses though!! Symlink it to ~/.config/mimeapps.list for the win. – Tom Hale May 29 '17 at 6:56
