Powershell比较对象但忽略特定字符？

以下代码片段显示了如何忽略驱动器号的一种可能方法：

Compare-Object $((Get-Content $Source1) -replace "\s[A-Z]\:\\", ' \') $((Get-Content $Source2) -replace "\s[A-Z]\:\\", ' \')

...是否还有一种简单的方法可以使用 compare-object 和/或 where-object 来吐出一个文件，该文件显示文件名匹配的位置，但哈希文件不匹配？这最终是我的目标是三个文件：源 A 中的文件不在 B 中。源 B 中的文件不在 A 中。然后是相同的文件名/路径但哈希不匹配？

我不确定这种三分法是否如上述补充要求中所述定义良好。但是，这是我解决它的尝试（稍微更改了变量和文件名）：

$sourcePath = 'D:\PShell\DataFiles'
$utf8     = 'utf8'     # $utf8 = 'Default'  # debugged using Default
$sourceA  = "$sourcePath\1558327A.txt"
$sourceB  = "$sourcePath\1558327B.txt"
$contentA = (Get-Content -Path $SourceA)
$contentB = (Get-Content -Path $SourceB)
$array = Compare-Object -ReferenceObject  $(
            $contentA -replace "\s[A-Z]\:\\", ' \')  -DifferenceObject $(
            $contentB -replace "\s[A-Z]\:\\", ' \')
$arrNotInB = $array | Where-Object {$_.SideIndicator -eq "<="} # |    Select-Object -ExpandProperty InputObject #| 
$arrNotInA = $array | Where-Object {$_.SideIndicator -eq "=>"} # |    Select-Object -ExpandProperty InputObject #|

# Files in Source B not in A. 
$arrNotInA |
    Select-Object -ExpandProperty InputObject |
    Where-Object {
        -not ($arrNotInB -match [regex]::Escape($($_ -split '\s', 2)[1]))
    } | Out-File -Width 512 -Encoding $utf8 -FilePath "$sourcePath\NotInA.txt"
# Files in source A not in B.
$arrNotInB |
    Select-Object -ExpandProperty InputObject |
    Where-Object {
        -not ($arrNotInA -match [regex]::Escape($($_ -split '\s', 2)[1]))
    } | Out-File -Width 512 -Encoding $utf8 -FilePath "$sourcePath\NotInB.txt" 
# And then same filenames/paths but with mismatched hash
(
$arrNotInB |
    Select-Object -ExpandProperty InputObject |
    Where-Object {
        ($arrNotInA -match [regex]::Escape($($_ -split '\s', 2)[1]))
    } | ForEach-Object {
        $auxHash, $auxPath = $_ -split '\s', 2
        $contentA | Where-Object {
            ($_ -replace "\s[A-Z]\:\\", ' \') -match [regex]::Escape("$auxHash $auxPath")
        }
    }
),(
$arrNotInA |
    Select-Object -ExpandProperty InputObject |
    Where-Object {
        ($arrNotInB -match [regex]::Escape($($_ -split '\s', 2)[1]))
    } | ForEach-Object {
        $auxHash, $auxPath = $_ -split '\s', 2
        $contentB | Where-Object {
            ($_ -replace "\s[A-Z]\:\\", ' \') -match [regex]::Escape("$auxHash $auxPath")
        }
    }
) | Out-File -Width 512 -Encoding $utf8 -FilePath "$sourcePath\NotMatchHash.txt"

样本数据：

# --- SourceA --    --- SourceB --
# --------------    --------------
# 123 c:\123.txt    123 c:\123.txt  <-- FullMatch
# 456 c:\456.txt    789 c:\789.txt  <-- NoMatch
# 0ab c:\0ab.txt    0ab d:\0ab.txt  <-- Hash + RelPathMatch

创建示例文件：

@'
123 c:\123.txt
456 c:\456.txt
0ab c:\0ab.txt
'@ | Set-Content A.txt
@'
123 c:\123.txt
789 c:\789.txt
0ab d:\0ab.txt
'@ | Set-Content B.txt

Import-Csv如果您可以控制源文件的创建，则可以将以下内容简化为操作：

Function Import-Log ($Path) {
   Get-Content $Path | ForEach{
      $_ -match '(^.+ )[A-Za-z]\:\\(.+$)' | out-null
      [PSCustomObject]@{
         Full    = $matches[0]
         NoDrive = $matches[1] + $matches[2]
      }
   }
}

定义了上述函数：

$oA = Import-Log A.txt
$oB = Import-Log B.txt

$NoMatches = Compare-Object $oA $oB -Property NoDrive
$AnotB     = $NoMatches | ? SideIndicator -like '<='
$BnotA     = $NoMatches | ? SideIndicator -like '=>'
$HashMatch = Compare-Object $oA $oB -Property Full, NoDrive | ? NoDrive -notIn $NoMatches.NoDrive

结果：

PS C:\> $NoMatches

NoDrive     SideIndicator
-------     -------------
789 789.txt =>
456 456.txt <=


PS C:\> $AnotB

NoDrive     SideIndicator
-------     -------------
456 456.txt <=


PS C:\> $BnotA

NoDrive     SideIndicator
-------     -------------
789 789.txt =>


PS C:\> $HashMatch

full           NoDrive     SideIndicator
----           -------     -------------
0ab d:\0ab.txt 0ab 0ab.txt =>
0ab c:\0ab.txt 0ab 0ab.txt <=
