title: Awk: Using invert match to a string and then substitute characters
body: <p>I want to extract lines that don't contain <code>#</code> and delete <code>"</code>, <code>;</code> in the output.</p>
  
  <p>My input FILE looks like this:</p>
  
  <pre><code># ;string"1"
  # string"2"; 
  string"3";
  </code></pre>
  
  <p>Can use <code>grep</code> and <code>tr</code> to get wanted output:</p>
  
  <pre><code>grep -v '#' FILE | tr -d ';"'  
  string3
  </code></pre>
  
  <p>However I want to use <code>awk</code>.</p>
  
  <p>I can extract invert match <code>awk '!/#/' FILE</code>, but how can I use <code>sub</code> to delete <code>"</code>, <code>;</code> in the same <code>awk</code> command?      </p>
