SU is the abbreviation for switch user, that is, switching users.

Enter "Exit" or "logout" at the terminal or use the shortcut "Ctrl+d" to return to the original user.

When switching users, if you want to use the new user's work environment after switching users, you can add between Su and username-for example: "Su-root"
