title: Adding characters to the beginning and end of a line starting with a specific string
body: <p>I have quite a few html files where I need to comment out a specific line of JavaScript:</p>
  
  <pre><code>&lt;script src="/common/javascript/jquery/jquery.tools-1.2.4.min.js" type="text/javascript"&gt;&lt;/script&gt;
  </code></pre>
  
  <p>What I would like to do via command line, is search .htm files in the directory for the string: "/common/javascript/jquery/jquery.tools-1.2.4.min.js" and add <code>&lt;!--</code> to the beginning of the respective line containing the string, and 
  <code>--&gt;</code> to the end of the line.</p>
  
  <p>Some files include <code>type=</code> and some do not, which is why I'd like to search using the src value and add to the beginning and end of line.</p>
  
  <p>Thanks for the help. I appreciate it.</p>
