Did you know that #Unix groups have passwords? Apparently if you set one, you then have to use newgrp to log in to that group.
I have never seen anyone use unix group passwords.
There are some things to say about this, but the first thing you might wonder is why the newgrp command exists at all. The best answer is that it's mostly a Unix historical relic (or, to put it another way, a fossil).
