7.7 A "Menu Prompt" for Naive Users

Some people don't want to be faced with a UNIX % or $ shell prompt. If you usually run only a few particular UNIX commands, you can put those command names in the shell prompt. Here's a simple one-line Bourne shell prompt for a .profile:

PS1='Type "rn", "mailx", "wp", or "logout": '

Next, a multiline prompt (7.5) for the C shell .cshrc file:

($?prompt)	if ($?prompt) then set prompt='\\ Type "rn" to read the news,\\ type "mailx" to read and send mail,\\ type "wp" for word processing, or\\ type "logout" to log out.\\ YES, MASTER? ' endif

You get the idea.
