title: Linux: Quiet mode and how to make command wait to finish before next
body: <p>If i do a command like say</p>
  
  <pre><code>yum install -y -q packageX
  </code></pre>
  
  <p>How do i ensure that it waits for finish before doing the next command?</p>
  
  <p>My goal is to have as little unnecessary output as possible but to do each command sequentially with each completing</p>
