I have a process I would like to kill:

computer@ubuntu:~$ ps aux | grep socat
root      2092  0.0  0.0   5564  1528 pts/1    T    14:37   0:00 sudo socat TCP:xxx.17.29.152:54321 PTY,link=/dev/ttyGPS0,raw,echo=0,mode=666
computer@ubuntu:~$ kill 2092
-bash: kill: (2092) - Operation not permitted   <--------------- How to kill ??

    The command you list here is running as root. Have you tried running sudo kill 2092? Sep 3, 2013 at 22:18

    I have a process that cannot be killed even with root (i'm running bash as root already). Any ideas what to try next?

    What process are you trying to kill and the error you are receiving?

    It is a stuck iftop and I get a "permission denied". Both iftop and kill are run by root itself. I started iftop from a bash and I can't kill that bash either.

    I have a process in which I did sudo kill -9 2091 and it still gives this message. Why would that be (os/x high sierra) Sep 29, 2018 at 19:05

    It seems there are some processes that cannot be killed even like this. I cannot kill softwareupdated like this.

That command is running under sudo as root, your kill command must as well:

sudo kill 2092
