shell脚本小游戏

这个话题非常广泛，可以有很多种实现方式。但是我可以给出一个简单的例子。

猜数字游戏：

#!/bin/bash

# generate a random number between 1 and 100
answer=$(($RANDOM % 100 + 1))

# while the user has not guessed the correct number
while true; do
  read -p "Guess a number between 1 and 100: " guess
  # check if the guess is less than the answer
  if [[ $guess -lt $answer ]]; then
    echo "Too low. Try again."
  # check if the guess is greater than the answer
  elif [[ $guess -gt $answer ]]; then
    echo "Too high. Try again."
  # if the guess is correct
  else
    echo "Congratulations! You've guessed the correct number."
    break
  fi
done

这就是一个简单的使用 shell 脚本编写的猜数字小游戏。运行后，程序会随机生成一个数字，然后提示用户猜测，根据猜测的结果告诉用户猜小了或猜大了。用户猜对了，程序就会提示并退出。
