login as another user in a terminal

This is an useful trick specially when we have specific users for certain services - like app servers-  the idea is to login temporally as another user in a terminal, do whatever you have to do and then logout, so, the steps are:

1. open a terminal
2. type: sudo -u myuser02 zsh
3. whoami

That's it, in this case, I use zsh as another terminal, you may use what you like.

Really useful, at least for me
