写一个有read和if判断的shell脚本

Sure, here's an example shell script that includes a read statement and an if statement:

#!/bin/bash

echo "Enter a number:"
read num

if (( num < 10 )); then
    echo "The number is less than 10"
else
    echo "The number is greater than or equal to 10"
fi

This script prompts the user to enter a number, reads in the input using the `read` statement, and then uses an `if` statement to check whether the number is less than 10. Depending on the result of the test, the script will output either "The number is less than 10" or "The number is greater than or equal to 10".

shell脚本用read写一个判断题

可以通过以下脚本实现一个简单的判断题：

#!/bin/bash

question="1+1=2. (T/F)" # 题目
answer="T" # 正确答案

echo $question
read user_answer # 获取用户输入的答案

if [ "$user_answer" == "$answer" ]; then # 判断用户答案是否正确
  echo "回答正确！"
else
  echo "回答错误！"
fi

你可以根据需要修改问题、答案和提示信息。运行脚本后，它将提示用户回答问题并给出相应的反馈。
