title: How to remove the last 13 (or n) characters of every line using Notepad++
body: <p>I have a file which each line that ends with <code>Mar 15, 2013</code> and other dates so I need to remove the end of each line say the last 13 characters</p>
  
  <p>Each line is a different length and has different characters so cant use anything as delimiters. </p>
