gvfs-mime --query {MIMETYPE} gvfs-mime --set {MIMETYPE} {HANDLER}

gvfs-mime can query information about applications that are registered to handle a mime-type, or set the default handler for a mime-type.

Gvfs obtains this information from the shared-mime-info database. The default handler is stored per-user, in the file $XDG_DATA_HOME/applications/mimeapps.list.

MIMETYPE should be a mime-type such as text/plain or application/mbox. HANDLER should be the name of an existing desktop file such as gedit.desktop.

The following options are understood:

-h, --help

Prints a short help text and exits.

--version

Shows the version number and exits.

--query

Query the handler for MIMETYPE.

--set

Set the default handler for MIMETYPE to HANDLER.

On success 0 is returned, a non-zero failure code otherwise.
