title: How to output a multiline string in Bash?
body: <p>How can I output a multipline string in Bash without using multiple echo calls like so:</p>
  
  <pre><code>echo "usage: up [--level &lt;n&gt;| -n &lt;levels&gt;][--help][--version]"
  echo 
  echo "Report bugs to: "
  echo "up home page: "
  </code></pre>
  
  <p>I'm looking for a portable way to do this, using only Bash builtins.</p>
