title: Is it possible to build variable names from other variables in bash?
body: <p>I apologise for the pretty terrible title - and the poor quality post - but what I basically want to do is this:</p>
  
  <pre><code>for I in 1 2 3 4
      echo $VAR$I # echo the contents of $VAR1, $VAR2, $VAR3, etc.
  </code></pre>
  
  <p>Obviously the above does not work - it will (I think) try and echo the variable called <code>$VAR$I</code> Is this possible in Bash?</p>
