There are 2 alternatives - vote for the best!

Terminal - Alternatives
traceroute 2>/dev/null -n google.com | awk '/^ *1/{print $2;exit}'

Know a better way?

If you can do better, submit your command here.

What others think

Am I wrong in thinking that "cat /proc/net/arp|grep eth0" provides basically the same information?

Or, even better:

grep eth0 /proc/net/arp
Comment by eightmillion 322 weeks and 5 days ago

That's wrong, /proc/net/arp contains the IP table.

By example, I have

IP address HW type Flags HW address Mask Device 0x1 0x0 00:00:00:00:00:00 * eth0 0x1 0x2 00:2e:e4:c5:91:7b * eth0

Another way is that :

traceroute 2>/dev/null google.com -n | awk '/^ [0-9]/{print $2;exit}'
