title: Increase variable count using i++ in shell script
body: <p>Code:   </p>
  
  <pre><code>website="https://www.test.com/"
  item_1="stuff"
  item_2="more-stuff"
  
          while [1]
          do {
              for (i=1; $i&lt;=3; i++)
                do {
                    echo $website$item_$i &amp;
                    sleep 2
                   }
                   done
             }
             done
  </code></pre>
  
  <p>Output I'm getting: </p>
  
  <pre><code>https://www.test.com/1
  https://www.test.com/2
  </code></pre>
  
  <p>Output I desire:</p>
  
  <pre><code>https://www.test.com/stuff
  https://www.test.com/more-stuff
  </code></pre>
  
  <p>I am trying to increment the "item" variables by using $i in place of the number, so I may loop through them, but it is not giving me the desired results. Is there a way to make this possible?</p>
