读取进程(gameserver)的控制台输出，并在出现单词"join“时执行一些操作

Question

我正在尝试设置一个linux l4d2游戏服务器，当有人加入大厅时，它会向我的团队发言发送一条消息。不知何故，我不知道如何在bash中运行该进程，以读取其内容并在有人加入时捕获。游戏服务器的输出清楚地显示了一行"XXXX加入了游戏“

Bash read output?不知何故不起作用。它冻结了这个过程。

output=$(./srcds_run)
while read -r line; do
    process "$line"
        if [ $line = "XXXX joined" ]; then
                echo "it works";
        fi
done <<< "$output"

当我运行它来启动服务器时，它在某一时刻挂起，并且没有启动。

Edit1：

Srcds_run的输出：

$ ./startServer.sh

这是用户"XXXX“连接和断开大堂时srcds_run的完整输出：

Client "XXXX" connected (127.0.0.1:27005).

请参阅http://forums.srcds.com/viewtopic/4446

您可以将输出写入日志文件并使用aka: tail -f /logfile|if "$(grep "XXXX“)”；然后回显"it works"；fi

Answer 2

根据我从问题中的评论和更新中收集到的信息，srcds_run是一个持续运行的进程/脚本。

所以在你的游戏结束之前output=$(./srcds_run)是不会终止的。(这是我的看法；可能是错的。)

但是，如果它是正确的，您可以尝试这样做：

$ ./srcds_run | grep --line-buffered "XXXX joined" | while read _; do
    echo it works
done

顺便说一句，从你的输出来看，你的游戏启动失败了，因为它找不到steam库。
