Sorry I accidentally sent the message immediately. I use this script:
catcher() {
echo caught.
}
set -o monitor
trap catcher SIGCHLD
for (( ;; )); do
echo sleeping.
sleep 2s &
echo reading.
read -t 5
echo ------
echo waiting.
wait
done
And the trap is always called every after 5 seconds when input already
times out:
sleeping.
reading.
caught.
------
waiting.
sleeping.
reading.
caught.
------
waiting.
sleeping.
reading.
...
Cheers, konsolebox
