Wow, that was fast. Indeed, from the source [1], see comment:
set_dns() {
# TODO: this should use scutil and be slightly more clever. But for now
# we simply overwrite any _manually set_ DNS servers for all network
# services. This means we get into trouble if the user doesn't actually
# want DNS via DHCP when setting this back to "empty". Because macOS is
# so horrible to deal with here, we'll simply wait for irate users to
# provide a patch themselves.
local service response
{ read -r _; while read -r service; do
[[ $service == "*"* ]] && service="${service:1}"
while read -r response; do
[[ $response == *Error* ]] && echo "$response" >&2
done < <(cmd networksetup -setdnsservers "$service" "${DNS[@]}")
done; } < <(networksetup -listallnetworkservices)
}
del_dns() {
local service response
{ read -r _; while read -r service; do
[[ $service == "*"* ]] && service="${service:1}"
while read -r response; do
[[ $response == *Error* ]] && echo "$response" >&2
done < <(cmd networksetup -setdnsservers "$service" Empty)
done; } < <(networksetup -listallnetworkservices)
}
If you'd like to contribute a patch to do this properly, please don't hesitate.
