CLI should trap signals and pass them on to processes

[technicalpickles]

I am trying to profile bin/rails server backgrounded in a script, and then kill it at the end. When I go to kill it, it seems to only kill the singed process, and rbspy that it is calling.

cleanup() {
        local pids
        pids=$(jobs -pr)
        if [ -n "$pids" ]; then
          echo "Killing processes: $pids"
          kill $pids
        fi
}
trap "cleanup" SIGINT SIGTERM EXIT

echo "Starting server"
bin/rails server &

I'm not sure if rbspy is smart enough to be able to dump its progress or not, but at least trapping and passing it on would be a good first step
