title: Powershell - print rows containing duplicate values in 3 columns
body: <p>I'm trying to output a file containing only the rows that have 3 duplicate values with 3 columns.</p>
  
  <p>Csv Current Example:</p>
  
  <p>I only want to find duplicates on columns (2, 3, <strong>and</strong> 5), then output these rows to a results csv file</p>
  
  <pre><code>Column1,Column2,Column3,Column4,Column5,Column6
  1a,32,46,1,1111,poiu
  2b,12,43,123,3333,zxcv
  3c,12,36,344,5555,asdf
  4d,12,36,64,5555,qwer
  5e,12,36,22,8888,lkjh
  6f,10,36,5432,7777,mnbv
  </code></pre>
  
  <p>The results csv file should have:</p>
  
  <pre><code>3c,12,36,344,5555,asdf
  4d,12,36,64,5555,qwer
  </code></pre>
  
  <p>Can anyone tell me how I can do this?</p>
