Question

所以，我正在尝试为我的程序创建一个安装向导。但是，如果你输入“n”，它会询问你是否确定要取消，但是当你按“n”时我希望它回到顶部。这可能吗？

echo "Would you like to start the NJDTL Install Wizard? [y/n]"
read startYN
if [ $startYN == y ]
  then
      echo "Starting Install Wizard. . ."
      mkdir ~/.NJDTL
    fi
    if [ $startYN == n ]
      then
          echo "Are you sure you want to cancel the Install Wizard? [y/n]"
          read CancelConfirm
          if [ $CancelConfirm = y ]
            then
                echo "Cancelling Install. . ."
                exit
              fi
          if [ $CancelConfirm = n ]
            then
                echo "Chose "n". Continuing Installation. . ."
        fi
