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? – Joel Taylor Sep 3 '13 at 22:18

try kill command with with -9 signal if sudo kill 'pid' does not work: sudo kill -9 2092

  • I have a process that cannot be killed even with root (i'm running bash as root already). Any ideas what to try next? – feedc0de Jan 15 '18 at 15:57
  • What process are you trying to kill and the error you are receiving? – Gr33n Jan 17 '18 at 0:44
  • 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. – feedc0de Jan 17 '18 at 9:45

    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) – javadba Sep 29 '18 at 19:05

    It seems there are some processes that cannot be killed even like this. I cannot kill softwareupdated like this. – jsky Jun 7 '19 at 3:04

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

sudo kill 2092
