[NMLUG] a way to "fake" interaction

[havoc at harrisdev.com (Jody Harris)]

Is there a tool I can use to respond to prompts?  I need to generate ssh 
key files on the fly, but there is no way to tell (at least not that I 
can find) ssh-keygen to not prompt for passphrase, just accept NULL.

If there is a tool that I could have "hit the enter key" for me when 
prompted, I'd be set.

thanks,
jody
