When you have finished using the computer, you should log out.
When you log out, no one can use your terminal until they correctly log in by typing a valid login name and password. Logging out protects you from other people doing potentially destructive things with your files if they are logged in as you. It is a good security practice.
The command you type to log out depends on the shell you are using. To log out using the Bourne shell, type exit and press <Enter>.
To log out using the C shell, type logout then press <Enter>.
You may also be able to log out using a quick <Ctrl>D However, this may be disabled on your system.
When you log out, the login: prompt reappears on your
screen.
Try logging out now:
login: prompt should
reappear on your screen.
Q: What if I see a message like:
exir: not found
A: In this example, the computer is telling you it cannot find a command named exir. What you meant, however, was ``exit''. Try typing the command again and press <Enter>.
Q: What if I try to log out with <Ctrl>D and I see a message like:
Enter "exit" to logout
A:
Some systems are set up so that you cannot log out with
<Ctrl>D. This is so that people do not accidentally log
themselves out when they are typing <Ctrl>D for another
reason. Follow the instructions on the screen to log out correctly.
Q: What if I change my mind when I am typing a command, and I want to cancel the command and start again?
A: There are two ways you can cancel the command you are currently typing and start over:
The <Del> key is called the interrupt key. You can use <Del> to interrupt a command that has started to run as well as to cancel a command you have not yet run. In most cases, this cancels the command and gives you a new prompt. (With some commands, you may need to press <Ctrl>D or a different quit command.)
