title: remove port number from list in notepad++
body: <p>I have csv file that has the computer name in one column, and the same computer name with the port number on the second column.  I want to compare that the name in both column 1 and 2 are the same.  So I am trying to remove the <code>:#####</code> from the list.  How do I do this?</p>
  
  <p>I can't post a picture as I am too new here, but it looks like  this:</p>
  
  <pre><code>ComputerName,ComputerName:18062
  
  ComputerName2,ComputerName2:198099
  </code></pre>
