It can be very frustrating when your professor says one thing about PowerShell and various websites seem to offer solid proof to the contrary. Does PowerShell actually work on non-Windows systems or not? Today’s SuperUser Q&A post has the answer to a puzzled reader’s question.

当您的教授对PowerShell发表一件事而各种网站似乎提供了相反的可靠证据时，这可能会非常令人沮丧。 PowerShell是否可以在非Windows系统上正常工作？ 今天的《超级用户问答》帖子解答了一个困惑的读者的问题。

问题 (The Question)

SuperUser reader FredSavage187 wants to know if PowerShell works on other operating systems besides Windows:

超级用户读者FredSavage187想知道PowerShell是否可以在Windows以外的其他操作系统上运行：

My computer science professor recently gave us a quiz and one of the questions was, “True or False: PowerShell works on Windows, Mac, and Linux”. The correct answer was “false” and he maintains that PowerShell is a Windows only thing. But I found a couple of websites that say otherwise:

我的计算机科学教授最近给我们进行了一个测验，其中一个问题是：“对还是错：PowerShell可以在Windows，Mac和Linux上运行”。 正确答案是“假”，他坚持认为PowerShell仅是Windows。 但是我发现有两个网站另有说明：

Which one is actually correct? Does PowerShell work on Linux and Mac OS as well as Windows?

哪一个是正确的？ PowerShell是否可以在Linux和Mac OS以及Windows上运行？

Does PowerShell work on other operating systems besides Windows?

PowerShell是否可以在Windows以外的其他操作系统上运行？

答案 (The Answer)

SuperUser contributor Ben N has the answer for us:

超级用户贡献者Ben N为我们提供了答案：

Yes. Much of PowerShell is .NET, so it can run on any operating system that has the Common Language Runtime (CLR). On Windows, that is the .NET Framework. For other operating systems, including Linux, you can use the , an open-source, cross-platform subset of the .NET Framework.

是。 PowerShell大部分是.NET，因此它可以在具有公共语言运行时(CLR)的任何操作系统上运行。 在Windows上，这就是.NET Framework。 对于包括Linux在内的其他操作系统，可以使用 (.NET Framework的开源，跨平台子集)。

As you learned at the PowerShell repository on GitHub, quite a few operating systems and distributions are supported. For example, here are the and a :

正如您在GitHub上的PowerShell存储库中了解到的那样，支持许多操作系统和发行版。 例如，这是的和一个 ：

One could argue that not all of PowerShell is available in non-Windows environments since some features depend on libraries found only in Windows. The ParsedHtml property on the HtmlWebResponseObject type returned by Invoke-WebRequest, for example, is only useful on Windows because it holds a COM object that comes from an unmanaged library, mshtml.dll to be specific. On other platforms, there is nothing there. And, of course, there are cmdlets to manage systems found only in Windows, like Modern apps (Get-AppxPackage, for example).

有人可能会说，并非所有PowerShell都可以在非Windows环境中使用，因为某些功能取决于仅在Windows中找到的库。 例如，由Invoke-WebRequest返回的HtmlWebResponseObject类型的ParsedHtml属性仅在Windows上有用，因为它包含来自非托管库(具体为mshtml.dll)的COM对象。 在其他平台上，没有任何东西。 而且，当然，有cmdlet可以管理仅在Windows中找到的系统，例如Modern应用程序(例如Get-AppxPackage )。

Still though, the PowerShell infrastructure works perfectly well on other operating systems, plenty of the cmdlets are usable anywhere, and support is only getting better.

尽管如此，PowerShell基础结构在其他操作系统上也能很好地运行，许多cmdlet都可以在任何地方使用，并且支持只会越来越好。
