Powershell 查找重复值并修改它们

Question

有一个解析 csv 文件的脚本，但它不能按需要工作 这是 csv 文件中的一些内容

id,location_id,name,title,email,department
1,1,Susan houston,Director of Services,,
2,1,Christina Gonzalez,Director,,
3,2,Brenda brown,"Director, Second Career Services",,
4,3,Howard Lader,"Manager, Senior Counseling",,
5,4,Kimberly Pesavento,Commercial director,,
6,5,Joe Bloom,Financial Empowerment Programs Program Director,,
7,6,peter Olson,Director,,
8,6,Bart charlow,Executive Director,,
9,7,Bart Charlow,Executive Director,,

Param 
( 
    [Parameter(Mandatory = $true, Position = 0)] 
    [string]$filePath 
) 
$inputFile = Import-Csv -Path $filePath
$text = (Get-Culture).TextInfo
$HashSet = [System.Collections.Generic.HashSet[string]]::new([System.StringComparer]::OrdinalIgnoreCase)

foreach ($line in $inputFile) {
    $name = $line.name
    $line.name = $text.ToTitleCase($name)
    $firstName = $line.name.split(" ")[0]
    $lastName = $line.name.split(" ")[1]
    $newEmail = ($firstName[0] + $lastName).toLower()

    if (!$HashSet.Add($newEmail)) {
        $line.email = ($firstName[0] + $lastName + $line.location_id + "@abc.com").toLower()
    }
    else {
        $line.email = ($firstName[0] + $lastName + "@abc.com").toLower()
    }
} 

$inputFile | Export-Csv -UseQuotes AsNeeded ./accounts_new.csv

这是脚本的输出

"id","location_id","name","title","email","department"
"1","1","Susan Houston","Director of Services","shouston@abc.com",""
"2","1","Christina Gonzalez","Director","cgonzalez@abc.com",""
"3","2","Brenda Brown","Director, Second Career Services","bbrown@abc.com",""
"4","3","Howard Lader","Manager, Senior Counseling","hlader@abc.com",""
"5","4","Kimberly Pesavento","Commercial director","kpesavento@abc.com",""
"6","5","Joe Bloom","Financial Empowerment Programs Program Director","jbloom@abc.com",""
"7","6","Peter Olson","Director","polson@abc.com",""
"8","6","Bart Charlow","Executive Director","bcharlow@abc.com",""
"9","7","Bart Charlow","Executive Director","bcharlow7@abc.com",""

正如您从最后两行中看到的那样，location_id 仅附加了第二封相同的电子邮件，但第一封保持不变，我如何将 location_id 添加到第一封邮件？

你能帮助我吗？谢谢！

我尝试使用 while 而不是 if 语句，但它对我没有帮助

我对此的看法是按 name 属性对 CSV 进行分组，然后如果有 2 个或更多对象具有相同的 name 值，则使用 location_id。为此，您可以使用Group-Object。

Param(
    [Parameter(Mandatory = $true, Position = 0)]
    [string] $FilePath
)

function ConvertTo-Email {
    param(
        [Parameter(Mandatory)]
        [string] $Name,

        [Parameter()]
        [string] $Location,

        [Parameter()]
        [string] $Domain = "@abc.com"
    )

    end {
        $newEmail = $Name.ToLower() -split 's+'
        $newEmail[0][0] + $newEmail[1] + $Location + $Domain
    }
}

$txt = (Get-Culture).TextInfo
$csv = Import-Csv -Path $filePath
$map = $csv | Group-Object Name -AsHashTable -AsString

$csv | ForEach-Object {
    $_.name = $txt.ToTitleCase($_.name)

    # if there is only one user with the same name
    if($map[$_.name].Count -eq 1) {
        # use their Name and Last Name only
        $_.email = ConvertTo-Email $_.name
        return $_
    }

    # else, use also their Location_Id
    $_.email = ConvertTo-Email $_.name -Location $_.location_id
    $_
} | Export-Csv -UseQuotes AsNeeded ./accounts_new.csv

在问题中使用示例 Csv 的输出将变为：

id location_id name               title                                           email              department
-- ----------- ----               -----                                           -----              ----------
