I could fiddle with `hwinfo --network` or try parse `ip l sh dev br0`

How about this?
% cat /sys/class/net/eth?/address
Wonderul, many thanks.
Or the long version:
/sbin/ifconfig [interface] | grep HWaddr | tail --bytes=20 | head --bytes=17
^^^^ ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
That is what I wanted to avoid because it will totally break when the locale
changes.
How could a locale change break a grep for HWaddr ?
No really, could you give an example, I never did use another locale
than EN.
Even if it would, couldn't you export the environment variable first ?
This will work on other dists aswell, where as /sys/class/net/eth?/address does
not exists on e.g. debian iirc.
Did you really need to mention the worst example!
(Anyway, even debian 3.1r4/2.6.8 has that sysfs file.)
Of course I had to! ;-)
Always consider "worst" case scenario :)
