I have a MIME definition file which is installed as part of a package:
$ rpm -ql virt-viewer | grep mime /usr/share/mime/packages/virt-viewer-mime.xml $ cat /usr/share/mime/packages/virt-viewer-mime.xml <?xml version="1.0" encoding="UTF-8"?> <mime-info xmlns="http://www.freedesktop.org/standards/shared-mime-info"> <mime-type type="application/x-virt-viewer"> <sub-class-of type="text/plain"/> <comment>Virt-Viewer connection file</comment> <magic priority="50"> <match value="[virt-viewer]" type="string" offset="0"/> </magic> <glob pattern="*.vv"/> </mime-type> </mime-info> But when I query the MIME database, it identifies it as text/plain
$ xdg-mime query filetype console.vv text/plain I cannot use xdg-open to open the file with remote-viewer, which is a pain (Google Chrome also does not work here). I tried to force reindexing MIME system cache without any luck:
$ sudo update-mime-database /usr/share/mime/ My local mime database is empty. What's interesting is Thunar opens the vv file correctly, it's xdg-open which does not work well. Looks like it must be using a different approach. I don't have GNOME or Nautilus installed at all on my system.
This is Fedora 23 with i3wm.
