Killing A Stopped Process

UNIX Tutorial Five

% kill %jobnumber
Does that not work on a stopped process? I've tried to kill a stopped process and it is not working. Or do you need a certain type of shell for this to work? I don't see anything about this in my man pages.

Please explain the distinction, if any, you make between a stopped and a suspended process.
Also, you suspect a certain type of shell is needed but fail to tell which one you are running.

Is says stopped or suspended when you use the "ps" command. That is one of the many options of "ps". I'm using bash.

for one, you'd need to be owner or superuser to effectively kill the job successfully, and you may actually have more success going after the PID if the original session (or console screen) is no longer available...
