Hello, I want to populate an array from a long running process, something
like:

long_running_process | while read line
do
  array+=$line
done

problem is, since long_running_process does not continually produce output
but only some times, when i try to interrupt this pipeline with ctrl-c I
have to wait until it produces some output for the process to terminate
(because, as I understand it, when it tries to write to the pipe it
receives a sigpipe due to it being already closed)

I have tried various constructs with trap and even coproc to be able to
intercept the ctrl-c and send a sigpipe to the long running process, but to
no result.

I wonder if someone has some solution to share for this problem, thanks
