Why doesn't it let me change DNS?

Question

linux

Ubuntu 16.04

sudo echo "nameserver 208.67.222.222" > /etc/resolvconf/resolv.conf.d/base
sudo echo "nameserver 208.67.220.220" > /etc/resolvconf/resolv.conf.d/head

Both commands give an error

zsh: permission denied: /etc/resolvconf/resolv.conf.d/base

How then to change the DNS (without masquerades and other additional utilities, and without changing the file manually, which is not recommended)

Answer 1

In this case, sudo refers to echo, and redirect to file is obtained on behalf of the current user
echo 'foo' | sudo tee /filename
