I have a stupid question.
I know in Ruby you can get the output of a command by encasing itin backquotes.

For example:

$ irb
irb(main):001:0> output = `uname -r`
=> "2.6.20-ARCH\n"

Now, my question. Say I have a program like apt-get (pacman in this case).
What I want to do is start the program from inside a Ruby script and see the output as it's running.

I think this is possible, because I've seen it done in other scripts (though not necessarily Ruby). Any ideas?
