title: Print from another function
body: <p>In order to save space on the codeline, I need to build a function to print out the info provided by another function, e.g:</p>
  
  <pre><code># (1-1) Install APP
  function installapp {
    echo "APP description goes here."
    echo "Installing..."
    xterm -e apt-get install app
    echo "APP Was Successfully Installed"
    echo "Run APP From The Menu"
    echo "Press Enter To Return To Menu"
    read input
  }
  </code></pre>
  
  <p>What I would like to know is how I can turn it into something like this:</p>
  
  <pre><code># (1-1) Install APP
  function installapp {
    echo "APP description goes here."
    echo "Installing..."
    xterm -e apt-get install app
    echo -e "$done(APP)"
    read input
  }
  </code></pre>
  
  <p>Where the <code>$done()</code> function has all the ending info quoted above.</p>
