lsof -i :port

or 

sudo kill $(sudo lsof -t -i:8000)

or 

sh killport 8000

The best way to kill a port in ubuntu terminal is fuser -k 9001/tcp

Answer 3

Its two steps process:

1. Know process id on port no. 8080 (can be any)

2. Kill process of that id 8689 (can be different)

   fuser -n tcp 8080
   
   #o/p 8080/tcp    8689
   
   kill -9 8689
