title: How to answer yes in Bash Script
body: <p>Have a quick question,</p>
  
  <p>imagine that I have this code:</p>
  
  <pre><code>mkdir -p $INSTALLDIR
  sudo apt-get install -y git clojure leiningen
  git clone git://github.com/maltoe/storm-install.git
  ./storm-install/storm_install.sh all `hostname` $INSTALLDIR
  </code></pre>
  
  <p>And this script will ask, do you want to install additional packages, and I want to say <code>yes</code>,
  How to do this automatically?</p>
  
  <p>Or may be there is a way to kinda answer yes to any question by default?</p>
