Subject: Invoking bash from Ruby

I'm a novice at Ruby, although I've been introduced to its syntax by
virtue of working with Puppet for the past 2 1/2 years. As a sys admin,
I'm most comfortable working with bash, but I recognize that there are
things that a
scripting language can't do - like interacting with a database. So I'm
writing some Ruby code to extract text out of an HTML file and then
insert it into a mySQL database. I've been using Nokogiri to get some
formatted text, but also need to get some text that's easy enough to get
with a scripting language like bash. Specifically, I need to do this:

grep "<strong>Date:</strong>" $1 | cut -d' ' -f3-5

Is there an easy way to embed this logic within Ruby code - or, better
yet - a way to do the same thing in Ruby?
