SESSION 3		UNIX COMMANDS


1. Login. The prompt should be displayed.

Press RETURN a few times. The prompt should be redisplayed each time you
press RETURN.


2. Enter the command
			who
and press RETURN.
This shows who is logged on, from what terminal (tty), the date and time
of logging in. This is your first example of a UNIX command.

ALL COMMANDS REQUIRE YOU TO PRESS RETURN FOR THEIR EXECUTION!


3. Enter
			who am i

This gives your login id and your terminal connection name.


4. Enter
			passwd

This will produce the prompt

			Old password:

Enter your existing password. It will not, for obvious security reasons,
be `echoed' to the screen. The next prompt will be

			New password:

Enter your desired new password. It must contain at least 6 characters 
and no more than 8, preferably containing a mixture of lower case, upper
case and numeric characters. But choose something which YOU will not 
forget (not your boy/girl friend's name for example). You will be 
prompted to repeat this

			Retype new password:

If the 2 entries agree then this will be your new password; the prompt 
will then be redisplayed.


5. Interrupt command.

If a command or program takes longer than you care to wait, you may 
interrupt it by typing the command
			
			ctrl c

This will stop the program and return you to the shell prompt.
