title: parsing a line in bash
body: <p>I have a file that has one entry per line. Each line has the following format:</p>
  
  <pre><code> "group:permissions:users" 
  </code></pre>
  
  <p>Permissions and users could have more than one value separated by comas like this:</p>
  
  <pre><code> "grp1:create,delete:yo,el,ella" 
  </code></pre>
  
  <p>I want is to return the following:</p>
  
  <pre><code>yo
  el
  ella
  </code></pre>
  
  <p>This is what I have so far:</p>
  
  <pre><code>cat file | grep grp1 -w | cut -f3 -d: | cut -d "," -f 2
  </code></pre>
  
  <p>This returns <code>yo,el.ella</code>, How can I make it return one value per line?</p>
