show gateway IP address when performing ifconfig command

Question

Currently, when using the ifconfig command, the following IP addresses are shown: own IP, broadcast and mask.

Is there a way to show the related gateway IP address as well (on the same screen with all the others, not by using 'route' command)?

The addresses shows are parameters of the IP configuration of the interface. The gateway is a system routing parameter, not an interface parameter. It wouldn't make sense to show it in the interface configuration. — David Schwartz, Oct 27 '11 at 10:33

You can with the ip command, and given that ifconfig is in the process of being deprecated by most distributions it's now the preferred tool. An example:

$ ip route show
212.13.197.0/28 dev eth0  proto kernel  scope link  src 212.13.197.13
default via 212.13.197.1 dev eth0

also we can use ip r which shows the same. – Rahul Patil Jul 31 '13 at 11:50

So the gateway is '212.13.197.1' in this example? – xxjjnn Aug 21 '15 at 09:57

route -n is so much cleaner of an output.. – Angry 84 Jan 11 '18 at 22:10
@Mayhem - Too bad "route -n" doesn't work for mac. Now "route -n get default" does work for showing the gateway on mac, but the one you suggested works on linux and not mac. – Alexis Evelyn Jul 31 '18 at 16:56

@SenorContento good thing the question was about linux and not a mac. – Angry 84 Aug 03 '18 at 01:10

For scripting: ip route show | sed 's/\(\S\+\s\+\)\?default via \(\S\+\).*/\2/p; d' – user541686 Jun 02 '19 at 03:08

Run:

$ route

The output is:

Kernel IP routing table
Destination     Gateway         Genmask         Flags Metric Ref    Use Iface
default         10.0.2.2        0.0.0.0         UG    1024   0        0 eth0

No, there isn't. According to the man page you can't modify the output of ifconfig (except showing disabled interfaces, too).
