기능 실행 후 메뉴 옵션을 표시하는 방법은 무엇입니까?

다음 스크립트가 있습니다.

while true; do
  echo "# Available tests:"
  PS3="Please select which test must be performed [1-9]: "
  options=("CPU Stress Test (local)" "Memory Stress Test (local)" "Intensive Random Write I/O on disks (5 min) (local)" "Intensive Random Read I/O on disks (5 min) (local)" "Intensive Read I/O on disks (5 min) (local)" "Intensive Write on disks I/O (5 min) (local)" "Cache Read Capability (local)" "Measure Network Bandwidth (Between nodes)" "Quit")
  select opt in "${options[@]}"
  do
    case $opt in
    "CPU Stress Test (local)")
            sleep 2
            cpu
            cleanup
    ;;
    "Memory Stress Test (local)")
            sleep 2
            memory
            cleanup
    ;;
    "Intensive Random Write I/O on disks (5 min) (local)")
            prereq
            cslist
            randwrite
            sleep 2
    ;;
    "Intensive Random Read I/O on disks (5 min) (local)")
            sleep 2
    ;;
    "Intensive Read I/O on disks (5 min) (local)")
            sleep 2
    ;;
    "Intensive Write on disks I/O (5 min) (local)")
            sleep 2
    ;;
    "Cache Read Capability (local)")
            sleep 2
    ;;
    "Measure Network Bandwidth (Between nodes)")
            sleep 2
    ;;
    "Quit")
            echo "All right, bye bye! :)"
            echo "Exiting..."
            sleep 2
            exit 1
    ;;
    *) echo "Invalid option ($REPLY)";;
    esac
  done
done

예를 들어 옵션 1을 선택하면 CPU Stress Test (local)성공적으로 실행되지만 결국에는 PS3옵션 없이 내 문제만 나타납니다 select opt in.... 누구든지 도와줄 수 있나요?

감사해요
