Kill execution of program being debugged.
kill('KILL', $$). This is an unmaskable signal. Use this when all else fails, e.g. in thread code, use this.
If you are in interactive mode, you are prompted to confirm killing. However when this command is aliased from a command ending in
!, no questions are asked.
kill kill KILL # same as above kill kill # same as above kill -9 # same as above kill 9 # same as above kill! 9 # same as above, but no questions asked kill unconditionally # same as above kill TERM # Send "TERM" signal
