How to kill a process on a port on ubuntu

Question

I am trying to kill a proccess in the command line for a specific port in ubuntu.

If I run this command I get the port:

sudo lsof -t -i:9001

so...now I want to run:

sudo kill 'sudo lsof -t -i:9001'

I get this error message:

ERROR: garbage process ID "lsof -t -i:9001".
Usage:
  kill pid ...              Send SIGTERM to every process listed.
  kill signal pid ...       Send a signal to every process listed.
  kill -s signal pid ...    Send a signal to every process listed.
  kill -l                   List all signal names.
  kill -L                   List all signal names in a nice table.
  kill -l signal            Convert between signal numbers and names.

I tried sudo kill 'lsof -t -i:9001' as well

Answer 6

FOR UBUNTU 1- Find what application/process is using the pro, type:

sudo netstat -lpn |grep :8080

and press Enter.

You will get an output similar to this one

tcp6       0      0 :::8080                 :::*                    LISTEN      6782/java

2- I have got the process Id, which is 6782, now this is the process that is using port 8080.

3- Kill the process, type:kill 6782

kill 6782
