title: Linux tr command
body: <p>I'm stuck and hope someone can help. I am trying to use the <strong><em>tr</em></strong> command to capitalize the text of first two columns of a file but can't seem to figure it out. It's actually for an assignment for a class I am taking and I must use <strong><em>tr</em></strong>. Can anyone help? </p>
  
  <p>Thanks in advance</p>
