打开文本文件并计算每个 IP 被列出的次数

Question

我有一个包含大量 IP 地址的文本文件，每个不同的 IP 可能在文本文件中多次出现，所以我正在尝试编写（或寻求帮助编写）一个 Powershell 脚本，它可以下列： 1 - 打开文本文件，计算每个 IP 出现的次数，然后 2 - 如果总数大于 20，则将该 IP 附加到另一个名为 Banned.txt

的文件

此脚本运行后，我会手动删除文件（该文件是由另一个程序创建的），几天后，我会再次执行此脚本。

这是我最好的尝试：

$BadIP = Get-Content -Path G:\ips.txt

foreach ($ip in $BadIP) {
    $matches = Select-String -InputObject $BadIP -Pattern $ip -AllMatches
    $a = $matches.Matches.Count
    $ip + " " + $a
}

以上代码有效，但一次又一次地显示相同的 ip。结果如下所示：

197.3.11.26   1
188.128.119.172   1
64.71.18.150   1
212.92.107.105   51
95.213.162.132   1
212.92.107.105   51
212.92.107.105   51
212.92.123.202   48
64.74.185.234   1
212.92.107.105   51
212.92.107.105   51
212.92.115.227   45
212.92.123.202   48
212.92.107.105   51
212.92.115.227   45
212.92.123.202   48

如您所见，212.92.107.105 显示了很多次。

更新：工作代码：

$BadIP = Get-Content -Path G:\ips.txt
foreach ($ip in $BadIP) {
    $matches = Select-String -InputObject $BadIP -Pattern $ip -AllMatches
    $a = $matches.Matches.Count
    if ($a -gt 10) {
        Add-Content -Path G:\NewBanned.txt -Value $ip -Force 
    }
}

$B = Get-Content -Path G:\NewBanned.txt | sort | Get-Unique
Set-Content -Path G:\C.txt -Value $B -Force

Answer 1

让 PowerShell 为您完成繁重的工作。 Group-Object cmdlet 将相同的输入 objects 分组并自动对它们进行计数：

Get-Content 'G:\NewBanned.txt' |
    Group-Object |
    Select-Object Name, Count

输出到这样的文本文件：

Get-Content 'G:\NewBanned.txt' |
    Group-Object |
    ForEach-Object { '{0}    {1}' -f $_.Name, $_.Count } |
    Set-Content 'G:\C.txt'

像这样输出到 CSV 文件：

Get-Content 'G:\NewBanned.txt' |
    Group-Object |
    Select-Object @{n='IPAddress';e={$_.Name}}, Count
    Export-Csv 'G:\C.csv' -NoType

后面计算的属性只是将"Name"替换为"IPAddress"作为列标题。

打开文本文件并计算每个 IP 被列出的次数

Open Text File and count how many times each IP is listed
