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
