you can use the following command to see the PID that is listening on port 5601

Copy to clipboard

```auto
lsof -i :5601

```

You could also use a derivate of your original approach looking for the process named 'node'

Copy to clipboard

```auto
ps -ef | grep node

```

but this has the potential to return processes besides the one you're looking for.  
Hope it helps.
