title: Loop background job
body: <p>I try to run a background job in a for loop in bash:</p>
  
  <pre><code>for i in $(seq 3); do echo $i ; sleep 2 &amp; ; done
  </code></pre>
  
  <p>I get error:</p>
  
  <pre><code>bash: syntax error near unexpected token `;'
  </code></pre>
  
  <p>In zsh the command line works.</p>
