How to kill a process on a port on ubuntu

Question

I am trying to kill a process in the command line for a specific port in ubuntu.

If I run this command I get the port:

sudo lsof -t -i:9001

You want to use backtick not regular tick:

sudo kill -9 `sudo lsof -t -i:9001`

If that doesn't work you could also use $() for command interpolation:

sudo kill -9 $(sudo lsof -t -i:9001)
