title: Add a header to a tab delimited file
body: <p>I'd like to add a header to a tab-delimited file but I am not sure how to do it in one line in linux.</p>
  
  <p>Let us say my file is:</p>
  
  
  
  <pre class="lang-none prettyprint-override"><code>roger\t18\tcolumbia\tnew york\n
  albert\t21\tdartmouth\tnew london\n
  etc...
  </code></pre>
  
  <p>and now I'd like to add a header that says:</p>
  
  <pre class="lang-none prettyprint-override"><code>name\tage\tuniversity\tcity
  </code></pre>
  
  <p>How would I do that in one line in linux?  I am ok with awk, sed, cat, etc. not familiar at all with perl though.</p>
