Aha... I was reading this article, and I got an easy solution:

Very similar to the above:

Create a file called whatever you want shown, say you want to be shown
using my_prog.  Make a file called my_prog and in it put this:

rlogin machine.com

Now, back at the shell prompt, type chmod u+x my_prog.  Then, type my_prog
at the prompt and you're on your way.  I don't think this will work under
BSDI, I can check if you really want me to, but I know it works under Linux.
