title: Can lsof show open ports on alpine linux?
body: <p>I have a spring boot app running in alpine linux listening on port 8080. However, when I do:</p>
  
  <pre><code>$ lsof
  $ lsof -i 8080
  </code></pre>
  
  <p>it doesn't show the open ports. Do you know what I am doing wrong?</p>
  
  <p>It almost seems that lsof on alpine linux isn't honoring any arguments. It always shows the same output - just seems to ignore -i.</p>
  
  <p>Thank you.</p>
