Powershell 比较多个电子表格并生成CSV输出

我试图比较两个csv文件，第一个文件名为tickets.csv，包含列标题：“tcn”、“two”、“twod”。第二个文件名为tracker.csv，包含标题：“cn”、“wo”和“wod”。我想输出tracker.csv的内容，如果任何“tcn”（tickets.csv）匹配“cn”（tracker.csv），那么将其关联的“two”（tickets.csv）写入“wo”（tracker.csv），将“twod”（tickets.csv）写入“wod”（tracker.csv）

我遇到了这样一个问题：我的代码没有移动“两个”或“wod”，而且还将每个对象写入4次

我以前看错方向了。但我明白了

$tracker = Import-Csv "$home\Desktop\nestTest\tracker.csv" |
ForEach-Object {
    $machine = ""
    $wo = ""
    $wod = ""
    $machine = $_.machine
    $tickets = import-csv "$home\Desktop\nestTest\tickets.csv" |
    ForEach-Object {
        $two = ""
        $twod = ""
        $two = $_."wo"
        $twod = $_."wod"
        $tcn = $_."cn"
        if ($tcn -eq $machine) {
            $wo = $two
            $wod = $twod
        }
        else {
        }
    }
        [pscustomobject]@{
        "Machine Name"=$machine
        "Work Order #"=$wo
        "Work Order Date"=$wod
        }

} |
select "Machine Name","Work Order #","Work Order Date" |
Export-Csv "$home\Desktop\nestTest\output.csv" -NoTypeInformation
