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. -- .-------------------------------------------------------------------------. | Only Amiga makes | Mike Dugas, aka White Trash | Only Commodore | | it possible... | mad@mv.mv.com | stood in the way.. | |--------------------'`------------------------------'`-------------------| | A2000-040/NEC CD-ROM/Flicker Fixer/210MB HD/9MB RAM | `-------------------------------------------------------------------------'
