title: How do I search and replace the contents of multiple Wordpress posts all at once?
body: <p>Ok I have over 500 posts on my website (<em>using wordpress</em>). I trying to replace the &lt; !--More--> tag in multiple posts to single line by itself.
  Example </p>
  
  <p><strong>This:</strong></p>
  
  <pre><code>Start of post.......
  
  &lt; !---more--&gt; ...post continues...
  </code></pre>
  
  <p><strong>To:</strong></p>
  
  <pre><code>Start of post.........
  
  &lt; !---more--&gt;
  
  ...post continues...
  </code></pre>
  
  <p>It would be great if there is no spacing between lines. Thanks in advance..</p>
