command killing ffmpeg simplified
ps aux | grep -ie ffmpeg
this command will always return a line, even when no ffmpeg process is running. This is because ps
will display grep -ie ffmpeg
on the process list and grep will match itself. To avoid this you should use a trick:
ps aux | grep -ie ffmpeg | grep -v grep
or run just a command that was designed for the purpose which is pkill
: pkill -9 ffmpeg
.
