title: Delete line in txt file based on token
body: <p>I have txt file full_add where I need to find and delete lines based on tokens in full_delete. Then, save full_add with the rest of the lines.
  This is sample data in each file:</p>
  
  <p>full_add</p>
  
  <pre><code>Employee,800751,,1,9999,,,,,
  Employee,800752,,1,9999,,,,,
  Employee,800761,,1,9999,,,,,
  Employee,800762,,1,9999,,,,,
  </code></pre>
  
  <p>full_delete</p>
  
  <pre><code>Employee,800751
  Employee,800762
  Employee,800742
  </code></pre>
  
  <p>final result in full_add after deliting</p>
  
  <pre><code>Employee,800752,,1,9999,,,,,
  Employee,800761,,1,9999,,,,,
  </code></pre>
  
  <p>This is my idea:</p>
  
  <pre><code>FOR /F "eol=; tokens=2 delims=," %i in (full_delete.txt) do find /v "%i" full_add.txt &gt; full_add.txt
  </code></pre>
  
  <p>I get empty file full_add. If I change <code>&gt;full_add.txt</code> for <code>&gt;tmp.txt</code>, it works but only delete the last token line found. Thanks. Frank</p>
