Subject: [ruby-talk:12304] How to pipe to an application?

I'm sure this is an easy one, but it is getting late in the day and my
creativity thread is not getting as many cycles as it was this morning.

I want to be able to write(print) to an application. I'v seen something
like this in perl with

open("| app")

From the shell I would do

cat msg | sendmail name@address.com

but I want to do this from within Ruby.
If I have msg as a string can I do

f = File.open("| sendmail")
f.puts msg

But, if I do, how do I specify the parameters following sendmail?

Thanks
