title: SED remove everything before string
body: <p>I have a plain Mail and i need to remove everything before <code>Summary of client activity for the last 24 hours
  </code> i thought it would work best with sed.</p>
  
  <p>I searched the internet but there it's just with a delimiter or something similar.</p>
  
  <p>You have any ideas?</p>
  
  <p>Part of the Mail:</p>
  
  <pre><code>...(Personal Part of the Email)...
  ...
  The following clients have no associated schedule
