A script that changes MAC address

Here is a script that can change your MAC address automatically. Just save it as ~/bin/macchange and add ~/bin to your path. Tested on Mac OSX Yosemite.

Type macchnage to change MAC address to a random one. Type macchange restore to restore MAC address to origin.

if [[ $1 == 'restore' ]]
then
  action='restored'
  mac=$(cat ~/bin/mac.origin)
else
  action='changed'
  mac=$(openssl rand -hex 6 | sed 's/\(..\)/\1:/g; s/.$//')
fi

sudo ifconfig en0 ether $mac

echo $action MAC to $mac

ifconfig en0
