shell脚本石头剪刀布五局三胜

可以为您提供一个简单的shell脚本来实现石头剪刀布游戏。下面是一个示例：

#!/bin/bash

player_score=0
computer_score=0
rounds=5
wins_required=3

declare -a options=("石头" "剪刀" "布")

function generate_computer_choice {
    computer_choice=$((RANDOM % 3))
}

function determine_winner {
    player_choice=$1
    computer_choice=$2

    if [[ $player_choice -eq $computer_choice ]]; then
        echo "平局！"
    elif [[ ($player_choice -eq 0 && $computer_choice -eq 1) || ($player_choice -eq 1 && $computer_choice -eq 2) || ($player_choice -eq 2 && $computer_choice -eq 0) ]]; then
        echo "你赢了这局！"
        ((player_score++))
    else
        echo "电脑赢了这局！"
        ((computer_score++))
    fi
}

function print_scores {
    echo "你的得分：$player_score"
    echo "电脑的得分：$computer_score"
}

echo "欢迎来到石头剪刀布游戏！"

while [[ $player_score -lt $wins_required && $computer_score -lt $wins_required && $rounds -gt 0 ]]; do
    echo "请选择（输入序号）："
    for index in "${!options[@]}"; do
        echo "$index. ${options[$index]}"
    done

    read -p "你的选择: " player_choice

    if [[ $player_choice =~ ^[0-2]$ ]]; then
        generate_computer_choice
        echo "你选择了：${options[$player_choice]}"
        echo "电脑选择了：${options[$computer_choice]}"
        determine_winner $player_choice $computer_choice
        ((rounds--))
        print_scores
    else
        echo "无效的选择，请重新输入！"
    fi
done

if [[ $player_score -eq $wins_required ]]; then
    echo "恭喜，你赢得了比赛！"
elif [[ $computer_score -eq $wins_required ]]; then
    echo "很遗憾，电脑赢得了比赛！"
else
    echo "比赛结束，没有胜出者！"
fi

您可以将以上代码保存为一个.sh文件（例如：game.sh），然后通过运行 `bash game.sh` 或 `./game.sh` 来执行脚本。

这个脚本允许玩家与电脑进行石头剪刀布游戏，共进行5局，其中一方先获得3局胜利即为最终胜利。每次游戏后会显示双方的得分。最终会显示比赛结果。
