Google Public DNS and `resolv.conf` - Utilize both addresses `8.8.8.8` and `8.8.4.4`

I can make Ubuntu use one of Google's Public DNS's with the following command



sudo echo nameserver 8.8.8.8 > /etc/resolv.conf


If I want to have the option to use either one, can I issue the same command, but with a comma and a space, to utilize both 8.8.8.8 and 8.8.4.4? Like this



sudo echo nameserver 8.8.8.8, 8.8.4.4 > /etc/resolv.conf


I don't want to break anything before I try this experiment. And if I want to ever disable this Google's Public DNS I imagine I simply do this



sudo gedit /etc/resolv.conf
# Delete the `nameserver 8.8.8.8, 8.8.4.4` line
# Save, exit, reboot, and go about my business

    Don't manually edit /etc/resolv.conf. It says so right in the file. Any changes that you DO make there are not lasting. Use the NetworkManager GUI to change the DNS server definitions for a given connection... like "Wired Connection".
