Not able to kill process by "kill -9 <PID>" [duplicate]

Question

I want to kill process, which related to rsync.

By entering ps axu | grep -i lsyncd, I receive information about one process:

andrej   10690  0.0  0.0  15984  1148 pts/1    S+   16:52   0:00 grep --color=auto -i lsyncd

But when I'm trying to kill it, by using sudo kill -9 10690 I receive:

 kill: (10690): There is no such process

Answer 1

You are trying to kill the command you are running.

The 10690 is a grep process. At the moment you are trying to kill it, it has been finished already.

Answer 2

Read man pgrep and use

pgrep lsyncd
pkill -9 lsyncd

You may have to preface pkill with sudo, if you don't own the process.
