To exit the shell when you are finished, type exit or press Ctrl+D. If you go to the shell from a Terminal window and you are using the original shell from that window, exiting causes the Terminal window to close. If you are at a virtual console, the shell exits and returns you to a login prompt.

If you have multiple shells open from the same shell session, exiting a shell simply returns you to the shell that launched the current shell. For example, the su command opens a shell as a new user. Exiting from that shell simply returns you to the original shell.
