Powershell计数在单个列中匹配变量

我有一个CSV文件，我做了很多工作。我最近的任务是添加摘要表

说到这里，我有一个CSV文件，我从一个网站上提取并发送了很多支票。代码如下：

$Dups = import-csv 'C:\Working\cylrpt.csv' | Group-Object -Property 'Device Name'| Where-Object {$_.count -ge 2} | ForEach-Object {$_.Group} | Select @{Name="Device Name"; Expression={$_."Device Name"}},@{Name="MAC"; Expression={$_."Mac Addresses"}},Zones,@{Name="Agent"; Expression={$_."Agent Version"}},@{Name="Status"; Expression={$_."Is online"}}
$Dups | Export-CSV $working\temp\01-Duplicates.csv -NoTypeInformation
$csvtmp = Import-CSV $working\cylrpt.csv | Select @{N='Device';E={$_."Device Name"}},@{N='OS';E={$_."OS Version"}},Zones,@{N='Agent';E={$_."Agent Version"}},@{N='Active';E={$_."Is Online"}},@{N='Checkin';E={[DateTime]$_."Online Date"}},@{N='Checked';E={[DateTime]$_."Offline Date"}},Policy
$csvtmp | %{
    if ($_.Zones -eq ""){$_.Zones = "Unzoned"}
    }
$csvtmp | Export-Csv $working\cy.csv -NoTypeInformation
import-csv $working\cy.csv | Select Device,policy,OS,Zones,Agent,Active,Checkin,Checked | % {
    $_ | Export-CSV -path $working\temp\$($_.Zones).csv -notypeinformation -Append
    }

第一个检查是重复的，我为此使用了单独的代码行，因为我想为重复创建一个CSV

第二个复选框使用“未分区”回填分区列下的所有空白单元格

第三件事是遍历整个CSV文件，并为每个区域创建一个CSV文件

这就是我的基地。我需要添加另一个CSV文件以获得区域信息的摘要。区域的格式为XXX-WS或XXX-SRV，其中XXX可以是3到17个字母

我希望汇总表是这样的

ABC         ###
ABC-WS      ##
ABC-SRV     ##

DEF         ###
DEF-WS      ##
DEF-SRV     ##

我的想法是对原始CSV文件进行计数，或者对每个CSV文件中的行数进行计数，然后减去1作为标题行

现在区域是动态的，所以我不能说我想要区域XYZ，因为该区域可能不存在

因此，我需要的是能够计算原始文件中类似的区域类型，并将其输出到数组或文件，这将是我首选的方法，以提供具有相同区域名称的项目数。我只是不知道如何编写它来查找和计算匹配的变量。下面是我试图用来获取计数的代码：

import-csv C:\Working\cylrpt.csv | Group-Object -Property 'Zones'| ForEach-Object {$_.Group} | Select @{N='Device';E={$_."Device Name"}},Zones | % {
$Znum = ($_.Zones).Count
   If ($Znum -eq $null) {
            $Znum = 1
        } else {
            $Znum++
    }

}
$Count = ($_.Zones),$Znum | Out-file C:\Working\Temp\test2.csv -Append

以下是完整代码减去报告键：

$cylURL = "https://protect.cylance.com/Reports/ThreatDataReportV1/devices/"
$working = "C:\Working"
Remove-item -literalpath "\\?\C:\Working\Cylance Report.xlsx"
Invoke-WebRequest -Uri $cylURL -outfile $working\cylrpt.csv
$Dups = import-csv 'C:\Working\cylrpt.csv' | Group-Object -Property 'Device Name'| Where-Object {$_.count -ge 2} | ForEach-Object {$_.Group} | Select @{Name="Device Name"; Expression={$_."Device Name"}},@{Name="MAC"; Expression={$_."Mac Addresses"}},Zones,@{Name="Agent"; Expression={$_."Agent Version"}},@{Name="Status"; Expression={$_."Is online"}}
$Dups | Export-CSV $working\temp\01-Duplicates.csv -NoTypeInformation
$csvtmp = Import-CSV $working\cylrpt.csv | Select @{N='Device';E={$_."Device Name"}},@{N='OS';E={$_."OS Version"}},Zones,@{N='Agent';E={$_."Agent Version"}},@{N='Active';E={$_."Is Online"}},@{N='Checkin';E={[DateTime]$_."Online Date"}},@{N='Checked';E={[DateTime]$_."Offline Date"}},Policy
$csvtmp | %{
    if ($_.Zones -eq ""){$_.Zones = "Unzoned"}
    }
$csvtmp | Export-Csv $working\cy.csv -NoTypeInformation
import-csv $working\cy.csv | Select Device,policy,OS,Zones,Agent,Active,Checkin,Checked | % {
    $_ | Export-CSV -path $working\temp\$($_.Zones).csv -notypeinformation -Append
    }

cd $working\temp;
Rename-Item "Unzoned.csv" -NewName "02-Unzoned.csv"
Rename-Item "Systems-Removal.csv" -NewName "03-Systems-Removal.csv"
$CSVFiles = Get-ChildItem -path $working\temp -filter *.csv 
$Excel = "$working\Cylance Report.xlsx"
$Num = $CSVFiles.Count
Write-Host "Found the following Files:  ($Num)"

ForEach ($csv in $CSVFiles) {
    Write-host "Merging $CSVFiles.Name"
}
    $EXc1 = New-Object -ComObject Excel.Application
    $Exc1.SheetsInNewWorkBook = $CSVFiles.Count
    $XLS = $EXc1.Workbooks.Add()
    $Sht = 1
ForEach ($csv in $CSVFiles) {
    $Row = 1
    $Column = 1
    $WorkSHT = $XLS.WorkSheets.Item($Sht)
    $WorkSHT.Name = $csv.Name -Replace ".csv",""
    $File = (Get-Content $csv)
    ForEach ($line in $File) {
        $LineContents = $line -split ',(?!\s*\w+")'
        ForEach ($Cell in $LineContents) {
            $WorkSHT.Cells.Item($Row,$Column) = $Cell -Replace '"',''
            $Column++
        }
        $Column = 1
        $Row++
    }
    $Sht++
}
$Output = $Excel
$XLS.SaveAs($Output)
$EXc1.Quit()
Remove-Item *.csv
cd ..\

找到了解决办法

$Zcount = import-csv C:\Working\cylrpt.csv | where Zones -ne "$null" | select @{N='Device';E={$_."Device Name"}},Zones | group Zones | Select Name,Count
$Zcount | Export-Csv -path C:\Working\Temp\01-Summary.csv -NoTypeInformation
