过滤Poweshell中的CSV文件

Question

我有一个备份报告的CSV文件，其中有多列。我只想获取那些使用特定存储集从未成功的客户。

样本输入文件为

Client Name,Save Set Name,Group,Status
a,All,Group1,Failed
a,SQL,Group2,succeeded
b,SQL,Group1,Failed
c,FS,Group1,Failed
d,DBA,Group1,Failed
e,RDM,Group1,Failed
a,ALL,Group2,succeeded
b,SQL,Group3,succeeded
c,SQL,Group4, Failed

输出

Client Name Save Set Name   Status  Group
a   All Failed  Group1
b   SQL Failed  Group1
c   FS  Failed  Group1
d   DBA Failed  Group1
e   RDM Failed  Group1
c   SQL Failed  Group4

预期输出

Client Name,Save Set Name,Group,Status
c,FS,Group1,Failed
d,DBA,Group1,Failed
e,RDM,Group1,Failed
c,SQL,Group4, Failed

在下面的命令中，我面临的问题是，我要让失败的客户端在其他组中获得成功。而我只希望那些具有存储集的客户端失败并且没有任何成功价值。状态。

Get-Content E:\Report\Daily_Failed.csv | 
    ConvertFrom-Csv | 
        Select-Object -Unique * | 
            Group-Object -Property 'Client Name', 'Save Set Name', 'Group' | 
                Where-Object { 0 -eq ($_.Group | Where-Object Status -eq 'succeeded').Count } | 
                    Select-Object -Expand Group | 
                        Select-Object "Client Name", "Save Set Name", "status", "Group" |
                            Export-Csv -NoTypeInformation E:\Report\Failed_$CurrentDate.csv

您可以使用Group-Object和Where-Object子句来完成此操作。

对于演示，我使用的是Here-String;在现实生活中，您可以使用

从文件中导入csv

$csv = Import-Csv -Path 'X:\yourInputFile.csv'

代码：

$csv = @"
Client Name,Save Set Name,Group,Status
a,All,Group1,Failed
a,SQL,Group2,succeeded
b,SQL,Group1,Failed
c,FS,Group1,Failed
d,DBA,Group1,Failed
e,RDM,Group1,Failed
a,ALL,Group2,succeeded
b,SQL,Group3,succeeded
c,SQL,Group4, Failed
"@ | ConvertFrom-Csv

$result = $csv | Group-Object 'Client Name' | ForEach-Object {
    $succeeded = $_.Group | Where-Object { $_.Status -eq 'succeeded' }
    if (!$succeeded) { $_.Group }  # never succeeded, so output these
}

# output on screen
$result | Format-Table -AutoSize

# output to CSV
$result | Export-Csv -Path 'X:\yourFilteredCsv.csv' -UseCulture -NoTypeInformation

结果：

客户端名称存储集名称组状态----------- ------------- ----- ------c FS组1失败c SQL Group4失败d DBA组1失败e RDM组1失败
