title: Remove multi-line comments
body: <p>How do I remove all comments if they start with /* and end with */
  I have tried the following. It works for one line comment.</p>
  
  <pre><code>sed '/\/\*/d' 
  </code></pre>
  
  <p>But it does not remove multiline comments. for e.g. the second and third lines are not removed.</p>
  
  <pre><code>/*!50500 PARTITION BY RANGE (TO_SECONDS(date_time ))
   PARTITION 20120102parti VALUES LESS THAN (63492681600),
  (PARTITION 20120101parti VALUES LESS THAN (63492595200) */ ;
  </code></pre>
  
  <p>In the above example, I need to <strong>retain the last ;</strong> after the closing comment sign.</p>
