linux awk

Linux iwlist输出到列表或变量,linux,awk,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“无线工具”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' 这为我提供了以下输出： Cell 01 - Address: 88:03:55:E8:3A:D0 Quality=23/70 Signal level=-87 d

我正在尝试创建一个php网页，让用户连接到无线网络。由于“无线工具”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'
这为我提供了以下输出：

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

有没有办法将结果保存在这样的变量中

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...
我尝试过使用AWK（gawk不可用），但没有成功

结果

iwlist wlan0 scan

根据您的解释，我在
awk
中启动了一个简单的解析器。实际上，我想知道你为什么排除了
gawk
。（您还标记了
linux
。您的linux发行版中是否有K&R awk而不是
gawk
？）

然而，
gawk
将提供更多的便利，但也可以不使用它。因为我的cygwin中实际上有
gawk
，所以我将它与
-c
一起使用，这应该将它限制为“传统awk”

不幸的是，我没有完全理解输出格式的逻辑，即如何制作这些
、WEP、
或
、WPA、WPA2 PSK
片段。顺便说一句，我相信您的第二个示例列表中的一些设置已经更改。因此，我省略了这一部分，并向您展示其余部分。遵循这个概念，您应该可以轻松地自己添加缺少的rest

文件
列出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")"
}
我已将您的第二个示例输入保存到一个文件
wlan.txt
，用于调试和演示。我在Windows 10（64位）上的bash/cygwin中这样做了：

注:

iwlist
似乎提供了引用的网络名称（对不起，ESSID）。所以，这让我怀疑逃跑：有可能逃跑吗？什么逃跑？（当一个网络用非字母数字字符命名，尤其是引号命名时，这种情况看起来会很有趣。）这必须进行分类。结果要么是一个复杂的不可回避的应用，要么一切（包括引用）都应该简单地按原样使用。。。
目前，网络名称的引号被简单地删除。

从
iwlan0 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，我几乎达到了我想要的结果：

iw-wlan0-scan|sed-e's|（在wlan|上）（在wlan|g|上）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";

}
当然，在

的帮助下进行了更新，但不要在egrep后向我们显示输出，而是向我们显示egrep的输入，因为如果您在解决方案的其余部分使用awk，则不需要egrep（您将需要）。为了帮助您设计解析iwslist输出的最佳工具，我们需要查看iwslist输出，而不是使用其他工具对其进行后处理后得到的结果。添加了iwslist wlan0 SCAN0的完整输出。现在，在给定该输入的情况下，包括预期的输出，您就可以开始使用了。不幸的是-c不支持移植运行awk-f list-ween.awk plan.txt会导致以下错误：awk:bad regex“[0-9”：不匹配[or][^awk版本甚至不支持--version或-W version我在文本中写道，我有
gawk
并使用
-c
让它像
awk
一样运行。关于reg.表达式，我不确定。我希望，
-c
参数也能涵盖预期的reg.表达式……真的很难找到谷歌的r（非gnu）awk。我相信我在公司办公室里有一本古老的教科书。可能是，我明天可以更新。可能是，在此期间，你试图自己摆弄注册表表达式。我仍然有点不确定你的awk：如果你有Linux（正如你标记的问题）它应该与GNU awk一起提供。但是，我发现。它没有提供
-c
选项。听起来像（可能是）你正在使用这个。（你有OS/X吗？）我在这本手册中查找了REs。乍一看，一切都很好，但我没有深入挖掘。顺便说一句，“古代教科书”是一条死胡同。它只提到了较少的细节-没有帮助。我正在一个旧设备上使用OpenWRT。iwlist毫无用处，切换到
iw wlan0 scan
，以减少乱七八糟的输出。awk样式看起来有点奇怪。我访问了您提供的链接。这个awk脚本的原始版本看起来更好，但实际上没有问题关于
KPN fon
问题：如果
或模式匹配可以帮助解决这个问题。（对不起，我不知道
