title: notepad++ check for duplicate lines complex
body: <p>Example</p>
  
  <p>40000+lines with guids like this:</p>
  
  <pre><code>GUID: 0981723409871243
  </code></pre>
  
  <p>Search across all GUID's for duplicates</p>
  
  <p>Example:</p>
  
  <pre><code>GUID: 124432408213
  GUID: 08917234071423
  GUID: 0189742381
  GUID: 08917234071423
  GUID: 0817423423
  GUID: 124432408213
  </code></pre>
  
  <p>I have TextFX and Compare but how would I find this part there is 2 <code>124432408213</code> and 2 <code>08917234071423</code></p>
  
  <p>out of 40,000 lines with possible duplicates I cant easily detect them I need a way to find duplicates.</p>
  
  <p>It would be to be something like GUID: "Search text after guid" next line then continue search for each GUID...I could write a custom program that can do this but...trying to avoid having to do this TextFX is pretty powerful just don't see a way to do something like this...</p>
  
  <p>I should add a little more info here example:</p>
  
  <p>[block1]
  guid: ????
  more info: ???
  [/block1]</p>
  
  <p>this is how each block is formatted..</p>
