Hello,
This might be a bit off topic, but can't find anything really useful
when searching the internet. So i hope someone can point me in the right
direction
I have to start 2 processes in the background (running in parallel),
capture their return codes and after all 4 have completed successfully i
want to continue with the main script.
Sofar i have this (below), however is this the proper way to do it?
#!/bin/sh -
PIDLIST=""
./childprocessA.sh &
PIDLIST="$PIDLIST $!"
./childprocessB.sh &
PIDLIST="$PIDLIST $!"
for PID in $PIDLIST; do
wait $PID
rc=$?
echo "Job $PID exited with status $rc"
if [ $rc -ne 0 ]; then
exit $rc
fi
done
**** the rest of the main script ****
Regards,
Nick
