title: Bash script equivalent commands to tr and shuf?
body: <p>I'm trying to create an insult generator for one of my classes and I'm not quite sure how to finish it. </p>
  
  <p>I have the whole thing doing what I want, but I need to convert the external commands I'm using in the script to bash equivalents.</p>
  
  <p>The file I'm reading from has 3 columns of words that together make up a Shakespearean insult. </p>
  
  <p>The code:</p>
  
  <pre><code>while read ; do
      Insult=$(shuf -n 1 | tr "\t" " ")
      echo "thou $Insult"
  done &lt; /class/SIG_data
  </code></pre>
  
  <p>The <code>tr</code> command is in there for readability, as the columns are separated with tabs. I just need to know how to do this without using <code>tr</code> and <code>shuf</code>.</p>
