title: How to determine if it is a ssh shell?
body: <p>I don't want some alias to work in case I <code>ssh</code> into a Linux box.</p>
  
  <p>How do I determine if it is a ssh or an actual terminal launch so that I can put an <code>indef</code> around my aliases?</p>
  
  <p>I am using <code>tcsh</code>.</p>
  
  <p>Thanks in advance </p>
