Question

listen to exam instructions you have used su to switch to the root user account to perform some system administration tasks. now you want to change back to your regular user account. which command should you use?

Answer 1

To switch back to your regular user account from the root user account, use the 'exit' command. This ends the root session and returns you to the session of the user who initially switched to root.

Step-by-step explanation:

If you have used su (substitute user) to switch to the root user account for system administration tasks and now wish to change back to your regular user account, you should use the exit command. This command will exit the current session, which is the root session in your case, and return you to the previous user's session. Alternatively, if you used su - username to switch to root, you could use su - username again, replacing username with your regular user's username, to switch back directly.
