[英]Comparing files based on version number and some other criteria and Formatting the output
我正在使用Powershell中的Compare-object根據大小,上次寫入時間和版本號比較2個文件。 我正在得到結果。 唯一的問題是如何從結果中獲取版本號的值。
function dll_compare(){
param($path1,$path2)
$first = Get-ChildItem -Path $path1 -Filter *.dll
$second = Get-ChildItem -Path $path2 -Filter *.dll
$diff = Compare-Object -ReferenceObject $first -DifferenceObject $second -Property Name, Length, LastWriteTime, VersionInfo -PassThru | Select Name, Length, LastWriteTime, sideindicator,@{n="path";e={$_.fullname}},@{n="VersionInfo";e={$_|Select-Object -ExpandProperty VersionInfo |Select-Object -Property Productversion}}
$diff}
結果采用以下格式:我希望versioninfo包含值,而不是“ @ {ProductVersion = 10.0.10240.16384}”
Name : PhotoViewer.dll
Length : 1827328
LastWriteTime : 7/10/2015 4:31:20 PM
SideIndicator : <=
path : D:\Site1\Dlls\PhotoViewer.dll
VersionInfo : @{ProductVersion=10.0.10240.16384}
替換此行:
$diff = Compare-Object -ReferenceObject $first -DifferenceObject $second -Property Name, Length, LastWriteTime, VersionInfo -PassThru | Select Name, Length, LastWriteTime, sideindicator,@{n="path";e={$_.fullname}},@{n="VersionInfo";e={$_|Select-Object -ExpandProperty VersionInfo |Select-Object -Property Productversion}
同
$diff = Compare-Object -ReferenceObject $first -DifferenceObject $second -Property Name, Length, LastWriteTime, VersionInfo -PassThru |
Select Name, Length, LastWriteTime, sideindicator,@{n = "path"; e ={ $_.fullname }}, @{n = "VersionInfo"; e = { $_.VersionInfo.Productversion }
