I have the following script:
# cat sub.sh
echo "start script: $$"
( sleep 3 && echo "3s have elapsed" ) &
pid=$!
echo "$pid started in background"
kill_job() {
echo "killing $pid"
kill "$pid"
}
trap "kill_job" 1 2 3 15
wait
echo "end script"
If I run this with NetBSD-7.1 /bin/sh, I get:
# /bin/sh sub.sh
start script: 11904
29622 started in background
3s have elapsed
end script
If I interrupt this script with Ctrl-C within 3s, I get:
# /bin/sh sub.sh
start script: 17936
28641 started in background
^Ckilling 28641
end script
# 3s have elapsed <-- output after "sleep 3" finishes
Why does the output still appear after the script has ended?
If I run this with /bin/ksh, I don't get any output after the
end of the script.
