title: Linux usermod user is currently used by process
body: <p>So I'm trying to change user502's directory using</p>
  
  <pre><code>usermod -d /home/user502home user502
  </code></pre>
  
  <p>When I enter than into the shell (I'm on root user) I get "usermod: user502 is currently used by process 4220" and I know the user isn't logged in or anything, I just made the user.</p>
  
  <p>How do I fix this?</p>
