Change MAC address

[imfromwales]

Actually yes, because it re-sets each time on restart, I can set the original as a variable, rather than output it to a file. Thanks for your help

Do you know any commands to take just the MAC address, rather than "ether a2456:A6" (so exclude the word ether)?

Actually I have found that the following command strips the word ehter V1=$(ifconfig en1 | awk '/ether/ {print $2}')

Although I am having trouble, once I have created a MAC address, assigning it to a variable, I can only echo it. Why cant I set the following to a variable?

echo -n $V2; dd bs=1 count=3 if=/dev/random 2>/dev/null |hexdump -v -e '/1 "-%02X"'

V2 is the first 6 characters of my MAC address, formated like a2-a3-a4
