pkill is the easiest command line utility

pkill -f node

or

pkill -f nodejs

whatever name the process runs as for your os

—- update —- It has been raised that this does not address killing a single node process and instead kills EVERY node process. If this is desired pkill is your tool, otherwise use one of the other accepted answers

    Just the heads up, it will disrupt your Skype, Slack, VSCode, etc. In other words, any program which has fired up nodejs process. – Aneel Ansari Sep 03 '18 at 02:56
  • Great solution to kill all node processes. – Keyur Chavda-kc1994 Oct 22 '19 at 09:50

    This is a poor solution because the question was how to kill a single Node.js process, but the solution is for killing *every* Node.js process. With Node apps becoming increasing common, the risk of killing something additional that you didn't intend is a possiblity. – Mark Stosberg Jun 17 '21 at 17:08

    @MarkStosberg agreed, this was a good solution 7 years ago but does not answer the question to a t. I can amend the answer with the caveat that it will kill all node processes – vbranden Jun 17 '21 at 17:11

sudo netstat -lpn |grep :'3000'

3000 is port i was looking for, After first command you will have Process ID for that port 

kill -9 1192

in my case 1192 was process Id of process running on 3000 PORT use -9 for Force kill the process

  • this helped me! somehow this approach gave me the node process ID I was looking for based on the blocked port, rather than `ps aux | grep node` thanks a lot! – danivicario Apr 03 '20 at 12:18

if you want to kill a specific node process , you can go to command line route and type:

ps aux | grep node

to get a list of all node process ids. now you can get your process id(pid), then do:

kill -9 PID

and if you want to kill all node processes then do:

killall -9 node

-9 switch is like end task on windows. it will force the process to end. you can do:

kill -l

to see all switches of kill command and their comments.

You can use the killall command as follows: 

killall node

Run ps aux | grep nodejs, find the PID of the process you're looking for, then run kill starting with SIGTERM (kill -15 25239). If that doesn't work then use SIGKILL instead, replacing -15 with -9.

First find the Process ID (PID) associated with the port:

lsof -i tcp:5000

That displayed for me

COMMAND   PID USER   FD   TYPE DEVICE SIZE/OFF NODE NAME
firefox  4228 ravi  243u  IPv4 484748      0t0  TCP localhost:36216->localhost:5000 (ESTABLISHED)
node    12675 ravi   21u  IPv4 231192      0t0  TCP *:5000 (LISTEN)
node    12675 ravi   24u  IPv4 485739      0t0  TCP localhost:5000->localhost:36216 (ESTABLISHED)

then kill the process with :

kill -9 12675

In order to kill use: killall -9 /usr/bin/node

To reload use: killall -12 /usr/bin/node
