title: Why does awk print the entire line instead of the first field?
body: <p>I'm trying to learn to use <code>awk</code> but it's not behaving how I expect. Here's my trouble:</p>
  
  <pre><code>$ echo "Hello brave new world" | awk "{print $1}"
  Hello brave new world
  </code></pre>
  
  <p>I expected to see "Hello", as this is the first field. Why don't the spaces count as field delimiters?</p>
