    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>&1
        

        you 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 -9
          

          is doing exactly?

            @l951b951

            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
            ps aux (partial list)
