1. “Switch to another console. Linux lets you use
   “virtual consoles” to log on to multiple sessions simultaneously,
   so you can do more than one operation or log on as another user.
   Logging on to another virtual console is like sitting down and
   logging in at a different physical terminal, except you are
   actually at one terminal, switching between login sessions.”
2. “Temporarily use a different shell. Every user
   account has a shell associated with it. The default Linux shell is
   bash; a popular alternative is tcsh. The last field of the password
   table (/etc/passwd) entry for an account contains the login shell
   information. You can get the information by checking the password
   table, or you can use the finger command.”
