# A question for curious reader:
# How to break shell pipeline as soon as 5 lines are found in the following command:
# ./my-program | head -n5
# When I tried to do it, pipeline was not actively terminated,
# unless the my-program will try to output a thousand more lines overflowing pipe buffer and terminating with Broken Pipe.
# But if my program just output 5 (or slightly more) lines and hang up, the pipeline is not terminated.
