title: Rearrange columns using cut
body: <p>I am having a file in the following format</p>
  <pre>
  Column1    Column2
  str1       1
  str2       2
  str3       3
  </pre>
  <p>I want the columns to be rearranged. I tried below command</p>
  <blockquote>
  <p>cut -f2,1 file.txt</p>
  </blockquote>
  <p>The command doesn't reorder the columns. Any idea why its not working?</p>
