Re: No luck trying to pkill play_vk with escape

[Zoltan Csahok]

Nate, try first the companion command 'pgrep play_vk' while vk is running.
If no output is produced (which I suspect) then try 'pgrep -f play_vk'.
If it outputs the PID then just replace pgrep with pkill.
If there is still no output, then I have no idea.
73,
