如何验证 while 循环并根据条件重复

Question

请帮忙！我被困住了。无论我做什么，脚本都无法正确执行。任何见解表示赞赏。

#!/bin/bash

Name=""
User_Number="0"

read -rp "What is your name? " Name
read -rp "Enter a number between 1-10. " User_Number

while (($User_Number <= 0 && $User_Number >= 11)) 
do
echo "The number you entered is invalid. Please try again." 
read -rp "Enter a number between 1-10. " User_Number
continue
echo "Hey ${Name}, the number you entered is: ${User_Number}."
done

while ((1 >= $User_Number <= 10)) 
do
echo -e "\nHello ${Name}!"
echo "The number you entered is: ${User_Number}"
break
done

如果用户的号码不在 1-10 范围内，我希望提示他们输入新号码。 发生的情况是，当我测试它时，范围之外的任何数字都会被视为在范围内。

我尝试重新排列 while 循环，将一个循环放在另一个循环之前，但无济于事。我尝试过通过一段 true if/then 语句将它们嵌套在一起，但这也不起作用。我在忽略什么？我尝试通过其他帖子寻求帮助。谢谢。 顺便说一句，我是 bash 脚本新手

你不需要脚本的结尾。我的脚本也使用

-lt

 表示小于，使用 

-gt

 表示大于。您应该检查

正确的语法以进行此类比较。

#!/bin/bash

Name=""
User_Number="0"

read -rp "What is your name? " Name

read -rp "Enter a number between 1-10: " User_Number

while [[ $User_Number -lt 1 || $User_Number -gt 10 ]]
do
  echo "The number you entered is invalid. Please try again." 
  read -rp "Enter a number between 1-10: " User_Number
done

echo "Hey ${Name}, the number you entered is: ${User_Number}."
