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.
Best Answer
pkill
has a-n
flag that will make it only affect the most recently started ("newest") matching process.If the
omxiv
process is well behaved, there is no need to use-9
.There is also a
-o
flag that will makepkill
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).
