hmmm, or something along the lines of
let n=0
let lim=3
while read task; do
$task &
if [[ $((++n)) -ge $lim ]]; then
wait
let n--
fi
done
while [[ $((n--)) -gt 0 ]]; do
wait
done
only because I dislike using sleep in any task just to avoid counting or
waiting properly. Have I got my pre-fix and post-fix operators on the right
side both times?
