$ gvfs-mount smb://192.168.0.4/tmp
This tool has been deprecated, use 'gio mount' instead.
See 'gio help mount' for more info.
However the gio mount help screen is not really all that much 'help'. Searching took me to this page: https://developer.gnome.org/gio/stable/GMount.html
which is also less clear than an un-muddied lake. I've tried all the options but non seems to mount the share. So does anyone have any idea of how to replace gvfs-mount.
