Bash 正在分析iw wlan0站转储输出

我知道这是一个类似的问题，从其他职位。但是我想解析iw wlan站点转储，并将最强站点信号的Mac地址保存到文本文件中，或者用python将其作为变量

比较具有不同信号的多个站点，数字越低表示最强。我需要比较来自多个站点的信号，并选择最强信号的mac地址，例如-55 vs-60

# awk '/Station/{val=$2;next} /signal/{sub(/^ +/,"");print "MAC Address: "val ORS $0;val=""}'

MAC Address: a8:83:02:cf:3d:e2
        signal:         -60 [-60] dBm
MAC Address: f4:60:e2:e2:2f:2e
        signal:         -55 [-55] dBm

从这里我想得到最低的数字。只需打印1个站点mac地址

所选信号的最新代码结果与mac地址不匹配

# iw dev wlan0 station dump | grep -E 'Station|signal' //Reference
Station a8:8e:08:cf:1d:e9 (on wlan0)    <-------
        signal:         -28 [-28] dBm
Station f4:20:e2:a8:3f:3e (on wlan0)
        signal:         -55 [-55] dBm
# sudo iw dev wlan0 station dump | awk //Command
MAC Address: f4:20:e2:a8:3f:3e          <-------
        signal:         -27 [-28] dBm

EDIT5：由于您没有告诉我mac地址可以在字符串station之后或字符串mac地址之后找到，所以我以前的代码只查找station string，现在我添加了逻辑来检查两者。考虑到这一点，你能不能在你的帖子中用代码标签发布sudo iw wlan0 station dump的输出，然后让我们知道？嗨@RavinderSingh13我刚刚发布了结果。谢谢，我在输出中没有看到频率信号加密字符串，那么如果这些字符串不在输出中，您的代码将如何工作？请告诉我您对输出中的哪个字段及其名称感兴趣？例如-->发送数据包etci试图仅获取电台和信号。请不要介意频率等。。我不知道如何显示带有信号的站点mac地址。注释不用于扩展讨论；这段对话已经结束。
