Custom MOTD for Raspberry Pi. Change city for weather (current is Lahore, Pakistan - you can get the city code [here](http://pastebin.com/dbtemx5F)), network interface (eth0 or wlan0, mine is wlan0 because i use wifi to connect to network), and /dev/root to your disk that you want to monitor. Add this to the end of .bashrc
