Is there a better way to check the exist status from a bunch of
background jobs in a script?
never used sigchild, but my answer would be to put them in an variable
or array and to wait for every process in turn :
pids=
sleep 60 &
pids="$pids $!"
sleep 60 &
pids="$pids $!"
for pid in $pids; do
wait $!
rc=$?
done
alternative :
npids=0
sleep 60 &
pids[npids++]=$!
sleep 50 &
pids[npids++]=$!
while :; do
for (pidn = 0; pidn < npids; pidn++); do
if ! kill -0 ${pids[pidn]}; then
wait ${pids[pidn]}
rc=$?
unset pids[pidn]
fi
done
(( ! ${#pids[*]} )) && break
sleep 10 # let's the cpu do something else
done
this solution also permit to handle a timeout if necessary.
PS : noth solutions not tested but should work.
