Some people don't want to be faced with a UNIX
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
PS1='Type "rn", "mailx", "wp", or "logout": '
multiline prompt (
for the C shell
if ($?prompt) then
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? '
You get the idea.
