title: escape dollar sign in bashscript (which uses awk)
body: <p>I want to use awk in my bashscript, and this line clearly doesn't work:</p>
  
  <pre><code>line="foo bar"
  echo $line | awk '{print $1}'
  </code></pre>
  
  <p>How do I escape <code>$1</code>, so it doesn't get replaced with the first argument of the script?</p>
