Script to kill applications listening to a port(s). Requires at least 2 parameters, the application and port, but could take in additional ports if more than one needs to be killed.

kill_server.sh

#! /bin/bash

PROC=$1

if [[ "$#" -lt 2 ]]; then
	echo "Requires at least 2 arguments, the process name and at least one port number."
	exit 1
fi

for ip in "$@"
do
	if [[ "$ip" -ne "$PROC" ]]; then
		echo "Stopping $PROC listening to $ip..."
		lsof -i ":$ip" | grep "$PROC" | awk '{print $2}' | xargs -L 1 kill
	fi
done

I have the script in a bin folder on my path and have the following alias in my zshrc.

alias kill_dc1="kill_server.sh node 8088 8089 9088"

The Lord's work, you do. 💯
