title: Bash - create alias that runs task in background AND carries on running other tasks
body: <p>My aim is to have an alias that will run commands like this:</p>
  
  <pre><code>alias thing="task_1 &amp; &amp;&amp; task_2"
  </code></pre>
  
  <p>The point being that task_1 is a long running task and should be started before task_2 but ultimately both should be running at the same time.</p>
  
  <p>Any suggestions?</p>
