在 PowerShell 中，结合这两个脚本，如果主机名 IP 与 DHCP 范围匹配，则附加 csv 输出

Question

我有两个脚本。我想采用第一个脚本并添加一个条件，如果主机名 IP 与 ScopeIP 匹配，则将该范围的名称添加到 Results.csv

This is my current output

This is what I want my output to look like

我试过导入两个输出的csv文件，然后比较，但我不想输出一个以上的csv文件。重新导入两个 csv 文件，然后比较两个 ScopeID 列，然后从单独的列中获取相应的范围名称似乎也太复杂了。

谢谢。

我的两个脚本：

使用输出到 Results.csv


$list = Get-Content C:\script\HostNames.txt #Defines content it pulls as list

$Output = foreach ($hostname in $list) #Calls each item in list a hostname and sends to output
{
    if (test-connection -count 1 -computername $hostname -quiet)  #checking if hostname is on line with 1 ping, If online run the following
    {
        $System = Get-WmiObject Win32_ComputerSystem -ComputerName $hostname | Select-Object -Property Name,Model 
        $BIOS = Get-WmiObject Win32_BIOS -ComputerName $hostname | Select-Object -Property SerialNumber
        $User = get-childitem "C:\Users" | Sort-Object LastWriteTime -Descending | Select-Object -first 1
        $mac = invoke-command -computername $hostname {(gwmi -class win32_networkadapterconfiguration).MacAddress | select -first 1}
        $IpV = (test-connection -ComputerName $hostname -count 1 | select -expandproperty IPV4Address).IPaddresstostring
        $parts = $IpV.Split(".")  #converts the last octet into a zero
        $parts[3] = "0"
        $ip2 = [String]::Join(".", $parts)
    }
    
    
    else #statement if hostname is not online
    { 
        write-host $hostname not online
    }

[PSCustomObject]@{ #Rename varibles in data pull for output file
        ComputerName = $hostname
        Model = $System.Model
        SerialNumber = $BIOS.SerialNumber
        LastUser = $User
        MacAddress = $mac
        IpAddress = $IpV
        IpScope = $ip2}
    

}
$Output

$Output | Export-Csv -Path C:\script\Result.csv -NoTypeInformation

获取 DHCP 范围名称和范围输出到 ServerScopes.csv


$DHServers = Get-DhcpServerInDC
foreach ($Server in $DHServers)
{

$scopes = Get-DHCPServerv4Scope -ComputerName $Server.DnsName | Select-Object Name, ScopeID #only getting the Name and ScopeID

ForEach ($Address in $scopes) 
    {
$DHCPServer = $Server.DnsName

$Address | Export-Csv "C:\script\Results\ServerScopes.csv" -Append -NoTypeInformation
    
    }
 }

Here is what my DHCP scope names output looks like

Answer 1

处理此问题的一种方法是获取第二个 CSV 数据并将其转换为散列 table。当然，我会在导出数据之前处理数据（或者仍然可以使用）但是从你的例子开始......

# Create a lookup table where the key is the ScopeID
$lookup = Import-Csv -Path "C:\script\Results\ServerScopes.csv" | Group-Object -Property ScopeID -AsHashTable

然后在您的第一个脚本中像这样在您的对象创建中添加一行

[PSCustomObject]@{ #Rename varibles in data pull for output file
    ComputerName = $hostname
    Model = $System.Model
    SerialNumber = $BIOS.SerialNumber
    LastUser = $User
    MacAddress = $mac
    IpAddress = $IpV
    IpScope = $ip2
    Name = $lookup[$ip2].name
}

Answer 2

$DHServers = Get-DhcpServerInDC #get DHCP info
$hashtable = @{} #create hash table

foreach ($server in $DHServers){
$scopes = Get-DHCPServerv4Scope -ComputerName $server.dnsname #get all scopes in DHCP   
    
    foreach ($_ in (Import-Csv C:\script\Asset_List.csv | Select-Object -ExpandProperty asset)){ #get hostnames from list          
        
        foreach ($scope in $scopes){            
            if($scope | Get-DhcpServerV4Lease -ComputerName $server.dnsname | Where-Object HostName -like "$_*" ){ #compares the hostname to find which lease it is in
                $scopename=$scope.name #matches give scope name
                $hashtable[$_] = $scopename #when a match is found, add keys and values to table
            } 
        }
    }
}

在 PowerShell 中，结合这两个脚本，如果主机名 IP 与 DHCP 范围匹配，则附加 csv 输出

In PowerShell, combine these two scripts where if the hostname IP matches the DHCP scope, append the csv output

powershell

csv

scope

ip

dhcp
