安装向导重启

Question

所以，我试图为我的程序做一个安装向导。 然而，如果你输入“n”，它会询问你是否确定是否要取消，但是当你按下“n”时，我希望它回到顶端。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 

Answer 1

要重新启动脚本：

exec $0 

更新 - 保存在命令行中，你可以使用：

exec $0 "$@"
