Basic MAC address spoofing script for Arch Linux.
Should also work on other systems, but Arch Linux uses different default names for its network devices.
Requires openssl for randomness and sudo.
$ ./spoof.sh
Generate a random MAC address and assign it to the default device (wlp7s0).
$ ./spoof.sh -i wlan -a dead:beef:face:b00c:cafe:babe -c
Set the MAC address of wlan to dead:beef:face:b00c:cafe:babe and do not color the output.
$ ./spoof.sh -h
Output command usage.
