Mime Type

Install the package xdg-utils.

In general, type these commands with bash-completion, and you'll see the right option.

Ask

Ask what type of application opens an mkv file:

xdg-mime query default video/mkv

Same with pdf:

xdg-mime query default application/pdf

Ask what file-type book.pdf uses.

xdg-mime query filetype book.pdf

Set

Set the mime type of mp4 videos to mpv.

xdg-mime default mpv.desktop video/mp4

You'll need to use the tab key a lot here, and remember many items start with org.

You can use an asterisk for everything in a category.

xdg-mime default org.gnome.font-viewer.desktop font/*

This often won't work as expected, because some fonts will have the type application rather than font.
