I’ve often struggled to find and kill a process using a certain port on archlinux. Mainly becuase most guides use netstat rather than ss.

Here is how I just killed the process using port 5000 using fuser.

sudo fuser -k 5000/tcp

You can also get information about the process by running lsof

❯ lsof -i :5000
COMMAND      PID   USER   FD   TYPE    DEVICE SIZE/OFF NODE NAME
