powershell - 是否可以同时打印文件字符串，文件哈希和上次修改日期？

Question

我试图弄清楚如何在文件夹中打印文件路径的列表，以及它们随附的校验和以及最后修改的日期。

我可以获得文件路径和校验和的列表:
Get-ChildItem -Recurse | Get-FileHash | Export-Csv -Path C:\Temp\ListOfHashes.csv
我还可以获得文件路径，校验和和最后修改日期的列表:

Get-ChildItem -File -Recurse |
Select DirectoryName,Name,@{N='Version';E={$_.VersionInfo.ProductVersion}},LastWriteTime,Length,@{N='FileHash';E={(Get-FileHash $_).Hash}} | Export-Csv -Path c:\temp\test11.csv

但是奇怪的是，第一个脚本(仅打印哈希值)对每个文件都有一个哈希值。第二个脚本显示文件路径，最后修改日期和哈希，但并不总是包含哈希。有人知道为什么吗？



我发现了问题所在:如果文件打开，它将无法写入哈希。该脚本以及下面的脚本都可以工作。

编辑:菲利普·弗里(Philip Fourie)的加入至关重要:

Get-ChildItem -File -Recurse |
Select DirectoryName,Name,@{N='Version';E={$_.VersionInfo.ProductVersion}},LastWriteTime,Length,@{N='FileHash'; E={(Get-FileHash -LiteralPath $_.FullName).Hash}} | Export-Csv -Path c:\temp \test789.csv`

这是你所追求的吗？

Clear-Host
Get-ChildItem -Path 'D:\temp' -File | 
Select-Object -Property * -First 3 | 
ForEach{
    [PSCustomObject]@{
        'BaseName'                    = $PSItem.BaseName
        'FullName'                    = $PSItem.FullName
        'Length'                      = $PSItem.Length
        'LastWriteTime'               = $PSItem.LastWriteTime
        'HashCode Based on Name'      = $PSItem.GetHashCode()
        'HashCode Based on FullName'  = $PSItem.FullName.GetHashCode()
        'File Hash Only'              = (Get-FileHash -Path $PSItem.FullName).Hash
        'File Hash'                   = Get-FileHash -Path $PSItem.FullName
    }
}
