Is there a command which lists the MAC addresses of all attached devices?

While looking for info on how to change my MAC address I came across a command which sent the MAC address of all your network devices to stdout.

I remember it being a three letter command, unfortunately I can't apropos anything that works, google isn't helping, and I can't find the original place I saw it.

I think arp -a comes close, but I remember this command printing mac addresses only.

I have only successfully used this in OS X.

arp ... I don't know of any other tool that would do what you ask.

[edit]
Heh ... after a quick look at arps man-page:

Code:

awk '$4 ~ /:/{print $4}' /proc/net/arp

You can try nmap

Code:

nmap 10.0.0.0/24 | grep MAC
