Subject: Controlling an interactive program from Ruby

Hi,

I want to control an interactive program from Ruby, in the Expect style.  
I'd normally use Expect, but I can't get it installed.  I was hoping I 
could use Ruby.

I want to copy a large number of files from a remote location using scp.
I already have a script that generates the entire list of files to copy, 
and figures out where each one goes.  The problem is that these are spread 
over 300 directories, and I don't want to type my password 300 times.

This is what I wantn to automate:

$ scp dcarrera@zeno:/data/tmp/filename some/directory/
$ dcarrera@zeno's password:

It seems like I should be able to handle that with Ruby.

Any ideas?

Thanks.
