SOLVED Command line to stop MM
-
I have successfully created my config.js file and MM works from the terminal when I type
npm startIs there a command to stop MM from the command line?
-
npm stop
-
It says “Missing Script: stop”
-
Did you run it from the MagicMirror directory?
If so, then NPM is ignoring it’s own documentation. I can’t help further, as I run it through PM2, and PM2 does the magic for me.
-
@l951b951 if you did it that way, ctrl-c should stop it without problem.
If u did
npm start &Then you will have to kill the processes to stop it.
i wrote a little script to do it
#!/bin/bash ps aux | grep node | grep -v "color" | awk '{print $2}' | xargs sudo kill -9the script will also work from another process instance
-
I ran it from ~/MagicMirror so I was in the directory. and all I typed was npm start.
My problem is that I want to be able to fire a script after a set time to stop the Magic Mirror. My goal is to attach a PIR motion sensor, and when someone comes close start the magic mirror, and after a few minutes with no motion, stop Magic Mirror and run another script. Maybe that helps understand my intent.

@sdetweil said in Command line to stop MM:
ps aux | grep node | grep -v “color” | awk ‘{print $2}’ | xargs sudo kill -9
Thank you for that. It worked, but gives me this: is it safe to ignore these warnings?

@l951b951 yes.,… if you start mm like this
npm start >/dev/null 2>&1you won’t get any messages
that means
send all stdout to /dev/null ( >/dev/null)
and send stderr to the same place as stdout (2>&1) -
Thank you, that combination is doing what I need it to do.
I’m marking this as solved, but I’d love to see a breakdown of what
ps aux | grep node | grep -v "color" | awk '{print $2}' | xargs sudo kill -9is doing exactly?
-
list all the processes , one per line
ps aux
of that list get all lines that have the word ‘node’
grep node
of that list get all lines that DO NOT have the word color
grep -v “color”
use awk to print just the process number (second space separated token) from each line
awk ‘{print $2}’
and the use sudo kill -9 to kill it, passing the process number using xargs
xargs sudo kill -9 ???
you can do each as one step
