How to kill nc -k -l without restart?

Question

I have a script running behind the screen which has a command nc -k -l 12345. Is there any workarounds I could kill this daemon without restarting the machine?

Ubuntu 14.04

Answer 1

If that nc process was started with exactly that command, and no other nc processes have exactly that command, you can do:

sudo pkill -fx 'nc -k -l 12345'

• -f matches the entire command line
• -x makes the match exact.
