如何导入 Powershell CSV 月份名称

Question

我有一个 CSV（5k 行），它是通过具有此标题的软件格式化的：

groupname,id,name,email,active,created,Last seen in software A,Last seen in software B,Last seen in software C,Software A,Software B,Software C

下面的行看起来像这样： test-group,userID123,John Doe,jdoe@company.com,Yes,18 May 2017,22 Jun 2020,22 Jun 2020,22 Jun 2020,No,Yes,Yes

---

我想知道，鉴于 CSV 的日期格式为“日、月名、年”，我该如何过滤数据。 例如：我想过滤我在过去 90 天内没有见过的人，并且结果只搜索“软件 A”是否为“是”。

我还想添加更多参数，例如查看用户是否有：-and (email -like "*company.com") 等。

我以前在 AD 上搜索过，但没有从 CSV 导入。

$daysnumber= Read-Host 'Days since login'
(get-date).adddays(-$daysnumber)
$data = import-csv "userlist.csv"
$data | foreach-object {
New-Object PSObject -prop @{
"Last Seen in Software A" = [DateTime]::Parse("$_.Last Seen in Software A")
}
}

---更新--- 我走上了另一条路。我已经替换了日期的格式，因此我不再需要处理月份名称。 但我在验证数据甚至在控制台上显示或输出到 CSV 文件时遇到问题..

#Reads the file and then change all the months name to numeric value for ease of acces and sorting.
$original_file = 'C:\SCRIPTS\data\export-users.csv'
$destination_file =  'C:\SCRIPTS\data\export-users-replaced.csv'
(Get-Content $original_file) | Foreach-Object {
    $_ -replace 'Jan', '01' `
       -replace 'Feb', '02' `
       -replace 'Mar', '03' `
       -replace 'Apr', '04' `
       -replace 'May', '05' `
       -replace 'Jun', '06' `
       -replace 'Jul', '07' `
       -replace 'Aug', '08' `
       -replace 'Sep', '09' `
       -replace 'Oct', '10' `
       -replace 'Nov', '11' `
       -replace 'Dec', '12' `
       -replace 'Never logged in', '01 01 1990' `
    } | Set-Content $destination_file

    

#properties    = 'groupname','id','name','email','active','created','Last seen in Jira Service Desk','Last seen in Jira Software','Last seen in Confluence','Jira Service Desk','Jira Software','Confluence'
Import-Csv $destination_file | ForEach-Object {
    $groupname += $_.groupname
    $id += $_.id
    $name += $_.name
    $email += $_.email
    $active += $_.active
    #JSD (Jira service desk)
    $lastjsd += $_."Last Seen in Jira Service Desk"
    #JSW (Jira Software)
    $lastjsw += $_."Last seen in Jira Software"
    #JCF (Jira Confluence)
    $lastjcf += $_."Last Seen in Confluence"
    $licjsd += $_."Jira Service Desk"
    $licjsw += $_."Jira Software"
    $licjcf += $_.Confluence
} 

# Write-Host $active

$daysnumber= Read-Host 'Cantidad de dias'
$emaildomain=Read-Host 'Dominio de mails. Escriba "@dominio.com"'
$days   =  (get-date).adddays(-$daysnumber).ToString('dd MM yyyy')
Write-Host "Si desea buscar licencias de Service Desk ingrese Service,
Si desea buscar licencias de Jira Software ingrese Software,
Si desea buscar licencias de Confluence ingrese Confluence"

$license= Read-Host " ( service / software / confluence ) "
    switch ($license) {
        service {Where-Object $lastjcf -LE $days | Format-List | Out-String | Export-Csv -Path "C:\SCRIPTS\jiratest.csv"   -Encoding UTF8 -Append -NoTypeInformation
         }
        software { Write-Host "nope"}
        confluence { Write-Host "no"}
    }

# Select-Object email -eq *$emaildomain* -and 'Last seen in Confluence' -le $days


# -and $licjsd -eq "Yes" -and $active -Is "Yes"

希望有人可以指导我如何制作这个低谷！

谢谢。

我认为没有必要将所有月份的短名称替换为数值，但下面我在 $format 变量前添加了注释，因此您可以根据需要进行设置。

另外，（据我所知）不需要为 CSV 中的所有字段创建类似数组的变量，因为在 Import-Csv 之后它们都可用。

试试这个缩短的代码：

# 'groupname','id','name','email','active','created','Last seen in Jira Service Desk','Last seen in Jira Software','Last seen in Confluence','Jira Service Desk','Jira Software','Confluence'
$data = Import-Csv -Path 'C:\SCRIPTS\data\export-users.csv'

$daysnumber  = Read-Host 'Cantidad de dias'                # remember that Read-Host returns a string
$emaildomain = Read-Host 'Dominio de mails. Escriba "@dominio.com"'
$days        = (Get-Date).AddDays(-[int]$daysnumber).Date  # get a DateTime object and disregard the time part (set to midnight)

Write-Host "Si desea buscar licencias de Service Desk ingrese Service,
Si desea buscar licencias de Jira Software ingrese Software,
Si desea buscar licencias de Confluence ingrese Confluence"

$license = Read-Host " ( service / software / confluence ) "

# the date format used to parse out the date from the CSV file
$format  = 'dd MM yyyy'   # for dates like '22 Jun 2020' use 'dd MMM yyyy'

switch ($license) {
    'service' {
        $fileOut  = 'C:\SCRIPTS\jiraServiceDeskTest.csv'
        $property = 'Last Seen in Jira Service Desk'
        $data | Where-Object { [datetime]::ParseExact($_.$property, $format, $null) -le $days } | 
                Export-Csv -Path $fileOut -Encoding UTF8 -Append -NoTypeInformation
    }
    'software' { 
        $fileOut  = 'C:\SCRIPTS\jiraSoftwareTest.csv'
        $property = 'Last seen in Jira Software'
        $data | Where-Object { [datetime]::ParseExact($_.$property, $format, $null) -le $days } | 
                Export-Csv -Path $fileOut -Encoding UTF8 -Append -NoTypeInformation
    }
    'confluence' { 
        $fileOut  = 'C:\SCRIPTS\jiraConfluenceTest.csv'
        $property = 'Last Seen in Confluence'
        $data | Where-Object { [datetime]::ParseExact($_.$property, $format, $null) -le $days } | 
                Export-Csv -Path $fileOut -Encoding UTF8 -Append -NoTypeInformation
    }
    default { Write-Host "Wrong input" } 
}

^{建议（稍后）添加测试以查看来自各种Read-Host cmdlet 的用户输入是否真的可以接受。}
