Then perhaps you could fix the locale in the invocation you want to use 
to extract the MAC address (just as you did to generate this example).


Though personally, I think using the system's introspection files 
(e.g., /sys/class/net/eth?/address), while not portable outside Linux, 
is a lot cleaner than scraping information from the output of commands 
that is intended to be read by humans.
