title: Bash - Calculate the Average of Numbers Inputted
body: <p>Need help with Linux Bash script. Essentially, when run the script asks for three sets of numbers from the user and then calculates the numbers inputted and finds the average. </p>
  
  <pre><code>#!/bin/bash
  echo "Enter a number: "
  read a
     while [ "$a" = $ ]; do
  
  echo "Enter a second set of numbers: "
  read b
  b=$
     if [ b=$ ]
  </code></pre>
  
  <p>Am I going about this wrong?</p>
