I need to write a script that, given a local IP address on a multi-homed host, will determine which NIC it is using and ultimately whether is it an ethernet or WiFi NIC? Can someone point me in the right direction? TIA.
There are many ways and utilities to find the desired information. Which one(s) to use depends on what distribution / version you are currently running.
If you are running a recent distribution with persistent naming just look at the output of the ip command.
Thanks for the reply. I don't see how the 'ip' command helps. I can't provide it with an IP address and get the information I want. I know I can write a complicated script that processes the output of 'ifconfig' but I was hoping for something easier.
