BasH:在后台运行脚本

Question

我正在尝试在后台运行两个脚本。但是，我想先运行一个脚本，等待它完成并递归运行下一个脚本。此代码片段会这样执行：

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
