Closing all processes holding a given port from shell

I am trying to automate one of the jobs I am facing again and again. There are some ports which are sometimes not closed correctly by some previous jobs..

Lets say port 5000,5001

WHat I want to do is see if these ports are open

and kill these ports if they are open

So right now, I am doing 

lsof -i :5000

and

 kill -9 pid1
    kill -9 pid2

and so on..

Is there a way to pass 5000 and 5001 as arguments and automate this process

If you want to automate it as you use it do something like this.

Create a bash script, for example call it 'killMyPorts' and add the following content:

#!/bin/bash
kill -9 `lsof -i :"${1}" | awk '{if (NR!=1) {print $2}}'`

Once you made the script executable (chmod u+x), you can execute it as follows:

./killMyPorts 5000

Have you tried

kill -9 `lsof -i :5000`

or

kill -9 $(lsof -i :5000)

fuser can do this job for you.

kill_port_users() {
  for port; do
    fuser -n tcp -k "$port"
  done
}

kill_port_users 5000 5001
