I was wondering if it is possible to write a scipt to execute three separate commands as root..the result of which is changing the mac address of my N810. Here are the three commands:

ifconfig wlan0 down

macchanger --r wlan0

ifconfig wlan0 up


Basically what I'd like to do is to be able to click just one button to change the mac, rather than have to go through the whole process. Any suggestions would be greatly appreciated!
