Kill second instance of a process












3















I'm running two instances of omxiv (Omx Image Viewer). The first instance acts like a background image, and the second instance acts as a slideshow. My question is how can I specifically kill the second instance?



Small note: The second instance will always be opened after the first instance.



I was thinking about killing it by pid, but I am not sure if it will have the same pid after the reboot, therefore this might not work.



Right now I am calling:



pkill -9 omxiv


which is terminating both instances.

          pkill has a -n flag that will make it only affect the most recently started ("newest") matching process.



          pkill -n omxiv


          If the omxiv process is well behaved, there is no need to use -9.



          There is also a -o flag that will make pkill send a signal to the oldest matching process.



          Note that using pkill -n will always kill the newest instance. If you have three processes, it will kill the third, not the second (as per title of question).

            @kasperd I was a bit careful, because OpenBSD pkill has some options not implemented on Linux systems, for example -q to be quiet.
