Linux openvpn auto reconnect script

auto-ovpn.sh

#!/bin/bash
export PATH=/usr/local/bin:/usr/bin:/bin:/usr/local/sbin:/usr/sbin:/sbin

### Thanks Xream's Work XD

# if you don't have several vpn servers to select, you can comment following line 
# and use your openvpn config file name to replace "${host}.ovpn" in while loop.

read -p "Select the host: " host

function getStatus () {
	ifconfig | grep $1 && return 1
	return 0
}

while [[ 1 ]]; do
	getStatus tun0
	if [[ $? == 0 ]]; then
		echo "openvpn is not connected!"
		echo "Reconnecting!"
                #Replace your_sudo_password to your real user sudo password.
		echo your_sudo_password | sudo -S openvpn --config /home/user/openvpn/${host}.ovpn
		sleep 6
	fi
	sleep 6
done

I have another question though... Is it possible to skip the step on the 9th line? "Select the host: "?
I'd like for the script to run at boot up. Perhaps there is a nother way to launch it at boot up?
