linux - iwlist 输出到列表或变量

标签 linux awk

我正在尝试创建一个 php 网页让用户连接到无线网络。由于“wireless-tools”是唯一可用的选项，我使用 iwlist 通过以下命令显示可用的 wifi 网络:

iwlist wlan0 scan | egrep 'Cell |Quality|ESSID|Auth|key|IE: IEEE|IE: WPA'

这给了我以下输出:

     Cell 01 - Address: 88:03:55:E8:3A:D0

                IE: IEEE 802.11i/WPA2 Version 1
                    Authentication Suites (1) : PSK

因为我想列出所使用的身份验证类型，所以我显示了加密，IE: IEEE 和 IE: WPA 列出了 WEP、WPA1 和 WPA2 PSK

有没有办法像这样将结果保存在变量中？

Cell 01 (88:03:55:E8:3A:D0, VGV7519E83ADB, WPA, WPA2 PSK, 23/70, -87)
Cell 02 (88:03:55:E8:3A:D1, KPN Fon, WEP, , 23/70, -87)
Cell 03 (90:5C:44:C5:B8:9D, Doggie, WPA, WPA2 PSK,  59/70, -51)
etc...

我试过使用 AWK(gawk 不可用)但没有成功..

结果

iwlist wlan0 scan

最佳答案

从 iwlist wlan0 scan 切换到 iw wlan0 scan，这提供了更清晰的输出。 当我偶然发现来自 Djey1301 的 GitHub 评论时，几乎得到了我想要的结果:29 sept 2016

iw wlan0 扫描 | sed -e 's#(在 wlan# (在 wlan#g' | awk -f scan.awk

扫描.awk:

BEGIN {

    printf("%s|%s|%s|%s|%s|%s|%s|%s|%s|%s\n","MAC","SSID","freq","signal","sig%","WPA","WPA2","WEP","TKIP","CCMP");

}
$1 == "SSID:" { buf = $2; for (i = 3; i <= NF; ++i) { buf = buf" "$i } ; e["SSID"] = buf ; next }
NF > 0{
if ($1 == "BSS") {
if( $2 ~ /^[a-z0-9:]{17}$/ ) {
if( e["MAC"] ){
printf("%s|%s|%s|%s|%s|%s|%s|%s|%s|%s\n",e["MAC"],e["SSID"],e["freq"],e["sig"],e["sig%"],e["WPA"],e["WPA2"],e["WEP"],e["TKIP"],e["CCMP"]);
}
    e["MAC"] = $2;
    e["WPA"] = "n";
    e["WPA2"] = "n";
    e["WEP"] = "n";
    e["TKIP"] = "n";
    e["CCMP"] = "n";
    }
}
if ($1 == "SSID:") {
e["SSID"] = $2;
}
if ($1 == "freq:") {
     e["freq"] = $NF;
}
if ($1 == "signal:") {
     e["sig"] = $2 " " $3;
     e["sig%"] = (60 - ((-$2) - 40)) * 100 / 60;
}
if ($1 == "WPA:") {
     e["WPA"] = "y";
}
if ($1 == "RSN:") {
     e["WPA2"] = "y";
}
if ($1 == "WEP:") {
     e["WEP"] = "y";
}
if ($4 == "CCMP" || $5 == "CCMP") {
     e["CCMP"] = "y";
}
if ($4 == "TKIP" || $5 == "TKIP") {
     e["TKIP"] = "y";
}
}
END {
      printf("%s|%s|%s|%s|%s|%s|%s|%s|%s|%s\n",e["MAC"],e["SSID"],e["freq"],e["sig"],e["sig%"],e["WPA"],e["WPA2"],e["WEP"],e["TKIP"],e["CCMP"]);
}

我几乎满意的结果:

MAC|SSID|freq|signal|sig%|WPA|WPA2|WEP|TKIP|CCMP
