Easy in bash:
if /sbin/route -n | grep "^0.0.0.0"
then
echo "Nothin' but 'net"
else
echo "Please connect to the 'net"
fi
All it does is check for 0.0.0.0 at the beginning of a line from the output
of route. That means that a default route has been established which should
mean an internet connection is supposed to be up.
