iwlist輸出到列表或變量

我試圖創建一個php網頁，讓用戶連接到無線網絡。由於「無線工具」是我使用iwlist顯示用下面的命令可用的WiFi網絡唯一可用的選項：iwlist輸出到列表或變量

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

這給了我下面的輸出：

        Authentication Suites (1) : PSK

因爲我想列出使用什麼類型的身份驗證我正在顯示加密，IE：IEEE和IE：WPA列出WEP，WPA1和WPA2 PSK

有沒有辦法將結果保存在像這樣的變量中？

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...

我用AWK（GAWK不可用），但沒有成功嘗試..

當然，但是不會告訴我們在egrep之後的輸出，向我們展示egrep的輸入，因爲如果您使用awk作爲解決方案的其餘部分（您將是），egrep將不是必需的。爲了幫助您設計解析iwslist輸出的最佳工具，我們需要查看iwlist輸出，而不是使用其他工具對其進行後處理後得到的結果。 –

添加iwlist wlan0掃描的完整輸出 – etimm

您到達那裏。現在包含輸入的預期輸出，並且您將擁有一些我們可以開始使用的內容。 –

從iwlist wlan0 scan轉換爲iw wlan0 scan，它提供了更清潔的輸出。幾乎得到的結果我的目標，當我從Djey1301偶然發現了一個GitHub的評論：29 sept 2016

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

scan.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"]); 
}

而結果我幾乎高興：

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

awk風格看起來有點奇怪。我訪問了您提供的鏈接。這個awk腳本的原始版本看起來更好，但這實際上是一個品味問題。關於'KPN fon'問題：一個額外的'if'或模式匹配可以幫助解決這個問題。（對不起，我不知道'iw wlan0 scan'的輸出，因此我不能建議添加實際的代碼行。） – Scheff

iw wlan0掃描的（部分）輸出： 'BSS 89:03:55 ：E8：3A：2B（上爲wlan0）' \t'TSF：12441130882601微秒（143D，23時52分10秒）' \t'頻率：2412' \t'信標間隔：100 TUs' \t'能力：ESS ShortSlotTime（0x0401）' \t'信號：-80.00 dBm' \t'最後看出：0毫秒ago' \t'從探測響應幀的信息單元：' \t'SSID：KPN Fon' \t支持率：1.0 * 2.0 * 5.5 * 11.0 * 9.0 18.0 36.0 54。0' \t'DS參數設置：通道1' \t'ERP：Barker_Preamble_Mode' （然後一些） – etimm

你能請編輯樣本輸入到你的答案（因爲缺少行尾可能成爲有助於提高awk掃描規則）。 – Scheff

結果根據你的解釋，我在awk開始一個簡單的解析器。其實，我想知道你爲什麼排除gawk。（您標記linux也。難道你真的有一個Linux發行版ķ& [R AWK代替gawk？）

然而，gawk將提供更多的方便，但它應該是可以不還。因爲我在我的cygwin中實際上只有gawk，所以我只用它-c，這應該將其限制爲「傳統awk」。

不幸的是，我完全不理解你的輸出格式的邏輯，即如何製作這些, WEP,或, WPA, WPA2 PSK件。順便說一句。我相信你的第二個樣本列表中的一些設置已經改變。因此，我把這部分留給了其餘的人。遵循這個概念，應該很容易地自行添加缺失的休息。

文件list-wlan.awk：

BEGIN { 
    #debug = 1 
    # states 
    cell = "" # current cell 
    addr = "" # current address 
    name = "" # current name 
    qual = "" # current quality 
    slvl = "" # current signal level 
} 

END { 
    # flush last cell 
    flushCell() 
} 

/^[ ]*Cell [0-9]+/ { # start of new cell 
    # flush previous cell 
    flushCell() 
    # skip prefix spaces 
    sub(/[ ]+/, "") # ; print $0 
    # extract cell and address from $0 
    sep = index($0, " - Address: ") 
    cell = substr($0, 1, sep) 
    addr = substr($0, sep + 12) 
    # debug 
    if (debug) print "cell: "cell" addr: "addr 
} 

/^[ ]*Quality=/ { # quality/signal level 
    # skip prefix spaces 
    sub(/[ ]+/, "") # ; print $0 
    # extract quality 
    match($0, /[0-9/]+/) ; qual = substr($0, RSTART, RLENGTH) 
    $0 = substr($0, RSTART + RLENGTH) 
    # extract signal level 
    match($0, /[-0-9]+/) ; slvl = substr($0, RSTART, RLENGTH) 
    # debug 
    if (debug) print "qual: "qual" slvl: "slvl 
} 

/^[ ]*ESSID:/ { # name 
    # skip prefix spaces 
    sub(/[ ]+/, "") # ; print $0 
    # extract name 
    match($0, /"[^"]*"/) ; name = substr($0, RSTART + 1, RLENGTH - 2) 
    # debug 
    if (debug) print "name: '"name"'" 
} 

function flushCell() 
{ 
    if (cell == "") return # nothing to flush 
    printf "%s(%s, %s", cell, addr, name 
    ## @todo missing authentification params... 
    print ", "qual", "slvl")" 
}

我救了你的第二個樣本輸入到調試和演示文件wlan.txt。我在Windows 10（64位）的bash/Cygwin的做：

$ awk -c -f list-wlan.awk wlan.txt 
Cell 01 (88:03:55:E8:3A:D1, KPN Fon, 29/70, -81) 
Cell 02 (90:5C:44:C5:B8:9D, Doggie, 58/70, -52) 
Cell 03 (54:FA:3E:60:F9:B1, HZN249093067, 21/70, -89) 
Cell 04 (64:D1:A3:31:D1:6C, Sitecom31D16A, 28/70, -82) 
Cell 05 (88:03:55:E8:3A:D0, VGV7519E83ADB, 30/70, -80) 

$

注：

的iwlist似乎提供引述網絡名稱（對不起，的ESSID）。所以，這讓我懷疑逃跑：是否有逃脫的可能？什麼逃避？（當網絡使用非字母數字字符命名，包括特別是引號時，這樣看起來會很有趣。）必須對此進行排序。結果要麼應用一個複雜的unescaping，要麼所有的東西（包括引號）都被直接使用...... 目前，網絡名稱的引號被簡單地刪除。

不幸的是-c不支持運行awk -f list-wean.awk plan.txt導致以下錯誤： awk：bad regex'[0-9'：Unmatched [or [^ awk version doesn' t甚至支持--version或-W版本 – etimm

正如我在文中寫的，我有'gawk'並使用'-c'來讓它表現得像'awk'。關於第表達式，我不確定。我希望，預期的章程。表達式將被'-c'參數覆蓋... – Scheff

使用谷歌很難找到（non-gnu）awk手冊。我相信我在公司辦公室裏有一本古老的教科書。可能是，我明天可以更新。可能是，你試圖搗鼓該區域。表達自己在此期間。 – Scheff
