if the process does not react on a normal kill, you may want to add an additional kill -9 a few seconds afterwards.

We can ask timeout to try to stop the program using SIGTERM, and to only send in SIGKILL if SIGTERM didn’t work. To do this, we use the -k (kill after) option. The -k option requires a time value as a parameter.

And if all else fails, you can just use a text editor.
