How to get system default gateway address in Linux + windows + MAC

Question

I have found a way to get default gateway in Linux with the following command:

grep -i "gateway" /etc/network/interfaces | awk print $2

Output:

192.168.14.1

This will not work if the system is in DHCP mode.

I need a way to get only 'gateway' which works on all platforms (Linux / Windows / Mac).

I think the OP meant getting the default gateway programmatically (not through the OS UI) – pedrohreis Dec 03 '19 at 21:54
