Who is using port 3000 ?

You start a Node App and You find that some other app is using 3000 Port ? You are too lazy to update env.PORT in the .env file because you want to know WHO IS USING THIS F## PORT?? then you open your Terminal and you COPY/PASTE This command:

sudo ss -lptn ‘sport = :3000’

Nice it’s a Node Docker container starting on a Port 3000 What a shame. Leaving a `docker-compose up -d` runing as a deamon.
