BasH：在后台运行脚本

Question

I am trying to run two scripts in the background. However I would like to have one script run first, wait for it to finish and run the next script recursively. Will this code snippet do as such:

for i in "${studyinstanceuids[@]}"
do
#let count="$count+1"
echo "$i" | ./cmd2&
sleep 5
if job1 is alive then sleep 5
      echo "$i" | ./sendExamToRepo.sh&
      wait
fi

Answer 1

for i in "${studyinstanceuids[@]}"; do
    ( echo "$i" | ./cmd2; echo "$1" | ./sendExamToRepo.sh )&
done
wait
