Stop node.js program from command line

Question

I have a simple TCP server that listens on a port.

var net = require(\"net\");

var server = net.createServer(function(socket) {
    socket.end(\"Hello!\\n\"         


        

Answer 1

You can use fuser to get what you want to be done.

In order to obtain the process ids of the tasks running on a port you can do:

fuser <>/tcp

Let's say the port is 8888, the command becomes:

fuser 8888/tcp

And to kill a process that is running on a port, simply add -k switch.

fuser <>/tcp -k

Example (port is 8888):

fuser 8888/tcp -k

That's it! It will close the process listening on the port. I usually do this before running my server application.
