使用shell脚本写石头剪刀布的脚本，三局两胜，无论谁赢，两局胜利后退出循环

当然可以，下面是一个简单的Shell脚本来实现石头、剪刀、布游戏，采用三局两胜制：

#!/bin/bash

# 定义三个选项和对应的数字
options=("rock" "paper" "scissors")
values=(1 2 3)

# 函数用于随机选择玩家的选择
choose_player() {
    echo -n "Player 1 (type 1 for rock, 2 for paper, 3 for scissors): "
    read player1
    if [[ ! $player1 =~ ^[1-3]$ ]]; then
        echo "Invalid choice, try again."
        choose_player
    else
        player1=$((player1 - 1))
    fi
}

# 函数判断胜负
judge() {
    result=$((2 - ($player1 % 3)))
    if [ "$player1" -eq "$result" ]; then
        echo "Tie!"
    elif [ "$player1" -eq "$((result - 1))" ] || [ "$player1" -eq "$((result + 2))" ]; then
        echo "Player 1 wins!"
    else
        echo "Player 2 wins!"
    fi
}

# 游戏循环
for ((i = 0; i < 3; i++)); do
    choose_player
    player2=$values[$RANDOM % 3]
    judge
    if [[ $(($i+1)) -eq 2 ]]; then
        break
    fi
    echo "Now let's play another round!"
done

echo "Game Over! The winner is..."
if [ "$player1" -eq 2 ]; then
    echo "Player 1"
else
    echo "Player 2"
fi

当你运行这个脚本，它会引导用户输入，根据随机选择的结果判断胜负，直到有一方赢得两局。每轮结束后会询问是否继续游戏，如果只玩三局，则在第二局获胜者后结束。
