sudo netstat -tunlp | grep :7777

You can use either netstat (deprecated) or ss, with the same options which are mnemonic:

-t = TCP
-u = UDP
-n = numeric output
-l = listening ports
-p = pid

Another commands that works, apart, from lsof, is fuser (the Linux one because the BSD's is different).

sudo fuser -n tcp -n 7777

You have to use following :

lsof -i :7777

I will show you pid without knowing the process name , but knowing the port no
