title: What is wrong with this line of code?
body: <p>I've got this code I can't seem to get running:</p>
  
  <pre><code> echo "digraph G{"; cat "$file"; echo "}" | dot -T png &gt; graph.png
  </code></pre>
  
  <p>The terminal echoes all it should but gets stuck on the } symbol. I guess there's something wrong syntactically.</p>
  
  <pre><code> Warning: &lt;stdin&gt;: syntax error in line 1 near '}'
  </code></pre>
  
  <p>Could you please be of quick help?</p>
