通过两个 bash 脚本进行通信

因此，我应该为“猜我的数字”游戏创建两个 bash 脚本。一个脚本用于庄家，另一个脚本用于玩家。

每个脚本都应等待对方生成响应（通过文件）后再继续。因此，当播放器启动时，它首先需要等待庄家的响应。当检测到响应时，播放器会获取庄家的响应并进行处理。当播放器做出猜测时，播放器会通过文件将该猜测传达给庄家。

当玩家猜测时，庄家会等待玩家的响应（通过文件）。当庄家检测到玩家的响应时，庄家会从文件中获取响应并继续进行。

下面是我在 bash 脚本中执行“猜我的数字”的 bash 脚本，但这仅在一个文件时才有效。

有人能告诉我如何将其拆分为两个脚本 (player_response.bash deal_response.bash) 并让它们通过文件进行通信并同时运行以实现相同的结果吗？非常感谢您的帮助！

        break;

有专门用于此目的的文件（即 IPC）称为命名管道。您可以使用命令创建它们mkfifo。以下是根据您的代码的一个非常基本的示例。dealer.sh必须首先执行，因为它负责创建和删除命名管道。

经销商.sh：

#!/bin/bash

dealerResponse=dealerResponse
playerResponse=playerResponse

mkfifo $dealerResponse
mkfifo $playerResponse

# delete the named pipes on exit
trap "rm $playerResponse $dealerResponse" EXIT

guess=1
n1=$(( ( RANDOM % 100 ) +1 ))

# this blocks until the player has read from the pipe
echo -n "Please make a guess: " > $dealerResponse

while read n2 < $playerResponse; do
    if [[ $n2 -eq $n1 ]]; then
        echo You win! > $dealerResponse
        break
    else
        if [[ $n2 -gt $n1 ]]; then
            echo -n "Sorry, your guess is too high. Guess again: " > $dealerResponse
        elif [[ $n2 -lt $n1 ]]; then
            echo -n "Sorry, your guess is too low. Guess again: " > $dealerResponse
        fi
    fi
    guess=$(( $guess + 1 ))
done

播放器

#!/bin/bash

dealerResponse=dealerResponse
playerResponse=playerResponse

while true; do
    read line < $dealerResponse
    echo -n "$line "
    read guess
    echo $guess > $playerResponse
done
