Change shell directory to one of the open directories in other shells

cd2

cd2 is a tiny handy tool for working with multiple console windows at a time. When called, it displays a list of all working directories of your running terminals and lets you choose one by simply entering a number. If you enter nothing it takes you to the last entry listed which makes a good default behavior. This way, when you open a new terminal window and type cd2 and press enter twice you can continue in the same wd as your other bash.
