Switch head of vdr frontend

Is there a simple way of calling the "switch head of vdr frontend" function on the command line rather than logging into the web interface?

Sorted:

sudo /usr/share/yavdr/events/change-display/00_switch-display
sudo /usr/share/yavdr/events/change-display/10_restart-vdr-frontend

So

sudo -s
echo "/usr/share/yavdr/events/change-display/00_switch-display" > /usr/local/bin/switch-head
echo "/usr/share/yavdr/events/change-display/10_restart-vdr-frontend" >> /usr/local/bin/switch-head
chmod +x /usr/local/bin/switch-head
switch-head
