Script to ping through tun0 and restart openvpn if connection lost

hi everyone :slight_smile:
it's that simple .. I live in somewhere that I always need vpn to do anything
my isp keep disconnecting every hour or so
all what I need is a script that keep pinging google every 5s
and if the connecting is lost just restart openvpn service after 30s
thanks for your time

pls can u explain the code for me ?
I want the to give 3 minutes for the first time to make sure the router is up and running
and then I want to ping every 5s and if the router lost the connection it will restart openvpn after 30s

while sleep 50; do
        t=$(ping -c $n | grep -o -E '\d+ packets r' | grep -o -E '\d+')
        if [ "$t" -eq 0 ]; then
                /etc/init.d/openvpn restart
