Hello fellow monks,
UPDATE:Thank you to all who replied. I got it working now. Unfortunately the ancient system I am running does not have Expect on it. I have been unsuccesful in previous attempts to get the sysadmins to add stuff for me. I know I *could* install it in my own directory (done that before too), but moot's suggestion works without having to do that.
Thanks again to everyone.

I am having a little trouble figuring something out and I would appreciate any help you guys can give.

I am trying to put together a perl script to run a variety of different daily checks that I need to run at work. There are several different tools that I need to execute. All but one of them will accept and argument as input, (it is written in C and I don't have the source code to modify). When I call "comparepass.exe" it responds with a list of valid files to check. I already know the name of the file I want to check so I don't really need the list, but with no command line arguments available, I can't override this action.

I know in Net::Telnet, I can issue a command, then use  $prev = $obj->prompt($matchop); to change the prompt and issue another command.

If I use system("comparepass.exe") or @response=`comparepass.exe`; It simply executes the command without giving me a chance to change the prompt or anything and give a secondary input. I know there has to be a way to do this in perl, but I can't find it in my searching, any help would be greatly appreciated.
