title: cut from column X until the end of a tab delimited file
body: <p>If I have a file with an unknown number of column but I know I want columns X til the end, is there an easy way to use cut for this?</p>
  
  <p>Let us say X=5,</p>
  
  <p>I used,
  <code>cut -f5- filename</code>
  but it did not work.  </p>
  
  <p>Then I am trying to specify the -d'\t' and also it does not work.</p>
  
  <p>Not sure what I am doing wrong.</p>
