title: How to prevent a background process from being stopped after closing SSH client in Linux
body: <p>I'm working on a Linux machine through SSH (Putty). I need to leave a process running during the night, so I thought I could do that by starting the process in background (with an ampersand at the end of the command) and redirecting stdout to a file.</p>
  
  <p>To my surprise, that doesn't work. As soon as I close the Putty window, the process is stopped.</p>
  
  <p>How can I prevent that from happening??</p>
