title: How to connect stderr to stdin using pipes?
body: <p>The "|" pipe operator connects the <strong>stdout</strong> of one process to the stdin of another. Is there any way to create a pipe that connects the <strong>stderr</strong> of one process to the stdin of another keeping the stdout alive in my terminal?  Searching on the internet gave me no information at all...</p>
  
  <p>Thank you in advance,
