Next, we can start inserting the command instructions that will allow us to manage the new service. The following block binds the command needed to start a VNC server, and feedback that it is being started, to the command keyword start.
case "$1" in
startvncstart)
log_action_begin_msg "Starting vncserver for user '${USER}' on localhost:${DISPLAY}"
su ${USER} -c "/usr/bin/vncserver ${OPTIONS}"
The next block creates the command keyword stop, which will immediately kill an existing VNC server instance.
stopvncstop)
log_action_begin_msg "Stopping vncserver for user '${USER}' on localhost:${DISPLAY}"
su ${USER} -c "/usr/bin/vncserver -kill :${DISPLAY}"
The final block is for the command keyword restart, which is simply the two previous commands (stop and start) combined into one command.
restartvncrestart) $0 stopvncstop $0 startvncstart
;;
esac
Now try using the service and command to start a new VNC server instance:
sudo service vncserver startvncstart
===Connect to VNC server===
