shell("netstat -i") has getting slow on MacOS10.x

[Marc Siskin]

Of the two commands, networksetup would require less parsing of the answer in order to get the device/MAC address pairing.

:)  you are right!

So I think I'll manage to replace the old and slow function using "netstat" by "ifconfig" as well as by "networksetup"
I have no idea, why the external programmer choose "netstat" at that time (2009). Does anybody see any pitfalls, why "ifconfig" or "networksetup" could return other results (after filtering, sorting etc.) or why I shouldn't use one of them? Are these commands the same available as netstat in modern Oss (> 10.9)? networksetup seems to be the easiest solution and is fast as ifconfig.

Thanks for any advice
Tiemo

If you call it with no arguments, doesn't it list them all?  I'll have to get my mac running again so I can test this stuff.

Yes, using ifconfig <interface> I get exact 1 MAC (see Ken Rays script
as Klaus pointed out). I don't see a parameter to get all at once, but
I could perhaps call ifconfig 4 times with <interface> lo0, en0,en1
and fw0. Or I will try to use "networksetup -listallhardwareports”, as
Marc pointed out Don't ask me why I need exactly these 4 interfaces.
The old function, working with netstat is made by an external
programmer and I have to get exact the same results as the old
function has provided, so I need these 4 interfaces.

That works great for the default adapter. I think Tiemo is looking for
a way to enumerate ALL adapter mac addresses. I have like 24 entries
using netstat. Some are ipv6 addresses, others ipv4, and still others
have no mac address at all. Of course I am using Parallels and have 2
physical network adapters and a couple virtual ones.
