# 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.
