我正在为MS PowerShell编写脚本.该脚本使用该Copy-Item命令.此命令的可选参数之一是" -container".该参数的文档声明指定此参数"在复制操作期间保留容器对象".

这一切都很好,因为在复制操作期间,我将是最后一个想要未预留容器对象的人.但严肃地说,这个论点有什么作用？特别是在我将磁盘目录树从一个地方复制到另一个地方的情况下,这对Copy-Item命令的行为有何不同？

我正在将一些 msbuild 脚本翻译为 powershell。

在 msbuild 中，我可以生成要（递归）复制到目标文件夹的文件的黑名单和/或白名单。

如下所示：

<Project xmlns="http://schemas.microsoft.com/developer/msbuild/2003" DefaultTargets="AllTargetsWrapped">

    <PropertyGroup>
        <!-- Always declare some kind of "base directory" and then work off of that in the majority of cases  -->
        <WorkingCheckout>.</WorkingCheckout>
        <WindowsSystem32Directory>c:\windows\System32</WindowsSystem32Directory>
        <ArtifactDestinationFolder>$(WorkingCheckout)\ZZZArtifacts</ArtifactDestinationFolder>
    </PropertyGroup>

    <Target Name="AllTargetsWrapped">

        <CallTarget Targets="CleanArtifactFolder" />
        <CallTarget Targets="CopyFilesToArtifactFolder" />
    </Target>

    <Target Name="CleanArtifactFolder">

        <RemoveDir Directories="$(ArtifactDestinationFolder)" Condition="Exists($(ArtifactDestinationFolder))"/>
        <MakeDir Directories="$(ArtifactDestinationFolder)" Condition="!Exists($(ArtifactDestinationFolder))"/>
        <Message Text="Cleaning done" />

        </ItemGroup>
