title: Print terminal alias command as well as executing it
body: <p>As a terminal noob, I've created aliases for pretty much everything I do. The problem is that I've started forgetting those few commands that I do know because of it. On top of that, I sometimes need to edit a variable in the previous command.</p>
  
  <p>So what I'd like is if when I use an alias, the first line printed is the actual command it represents, then proceed to execute the command. Since pressing up and <code>!!</code> simply reprints the alias, I'm not too sure how to get a reference to the underlying command. </p>
  
  <p>Thanks.</p>
