title: Grep for a special pattern
body: <p>I am looking for a pattern like the one below- </p>
  
  <pre><code>.mm1(moda.portb)
  .mab(blah.pc)
  </code></pre>
  
  <p>I am trying this-</p>
  
  <pre><code>grep -ir ".(*.*)"  .
  </code></pre>
  
  <p>Unfortunately, with this expression, i get a lot of results like-
  .mm1(moda)
  .mab(blah)</p>
  
  <p>How do I change my pattern so i can grep all files in my directory with an expression that is - <code>.characters(characters.characters)</code></p>
  
  <p>Help is appreciated, thanks !</p>
