您还可以尝试使用BashWin at在Windows上运行Bash脚本 https://github.com/skanga/BashWin。

当您将PowerShell与Cygwin/Perl/Shell组合进行比较时，请注意PowerShell仅表示该组合的“Shell”部分。

然而，您可以从PowerShell调用任何命令，就像从cmd.exe或Cygwin中调用一样。它没有重新实现指定的函数，当然也不能与Perl相比。

它“只是”一个外壳，但它使编程变得更容易，为。net世界提供了一个舒适的接口。

还要记住，PowerShell需要Windows XP、Windows Server 2003或更高版本，这可能会造成问题，具体取决于您的IT基础设施。

更新:

我不知道我的回答会引发什么样的哲学辩论。

我在这个问题的背景下发布了我的答案:将PowerShell与Cygwin、Perl和Bash进行比较。

PowerShell是一个shell，因为它在内置命令、命令行、用户函数和外部命令(.exe、.bat、.cmd)之间没有语法上的区别。只有在调用中添加名称空间或对象才能调用。net方法。

它的可编程性来源于。net框架，而不是任何特定于PowerShell“语言”的东西。

我想说，一旦Bugzilla或MediaWiki被实现为运行在web服务器上的PowerShell脚本，我相信PowerShell就是一种“脚本语言”。

在那之前，享受比较吧。

PowerShell中的cmdlet非常好，工作可靠。因为我是一名Java/ c#开发人员，所以它们的面向对象性非常吸引我，但这并不是一个完整的集合。由于它是面向对象的，因此它错过了POSIX工具集(例如awk和sed)的许多文本流成熟度。

The best answer I've found to the dilemma of loving OO techniques and loving the maturity in the POSIX tools is to use both! One great aspect of PowerShell is that it does an excellent job piping objects to standard streams. PowerShell by default uses an object pipeline to transport its objects around. These aren't the standard streams (standard out, standard error, and standard in). When PowerShell needs to pass output to a standard process that doesn't have an object pipeline, it first converts the objects to a text stream. Since it does this so well, PowerShell makes an excellent place to host POSIX tools!

最好的POSIX工具集是GnuWin32。它确实需要超过5秒钟的时间来安装，但这是值得的，据我所知，它不会修改你的系统(注册表，c:\windows\*文件夹等)，除了将文件复制到你指定的目录。这是非常好的，因为如果您将工具放在共享目录中，许多人可以同时访问它们。

GnuWin32安装说明

下载并执行exe(它来自SourceForge网站)指向一个合适的目录(我将使用C:\bin)。它会在那里创建一个GetGnuWin32目录，你将在其中运行download.bat，然后是install.bat(不带参数)，之后会有一个C:\bin\GetGnuWin32\gnuwin32\bin目录，这是Windows机器上曾经存在过的最有用的文件夹。将该目录添加到路径中，就可以开始了。

我发现PowerShell编程不值得付出努力。

我有几年在Unix下编写shell脚本的经验，但是我发现用PowerShell做任何事情都非常困难。

似乎许多函数都需要您查询Windows管理界面并发出类似sql的命令来获得所需的信息。

例如，我想编写一个脚本来从目录树中删除具有特定后缀的所有文件。在Unix下，这将是一个简单的…

find . -name \*.xyz -exec rm {} \;

在几个小时的脚本之后。FileSystemObject和WScript。Shell并发出“SELECT * FROM Win32_ShortcutFile WHERE Drive = '”& Drive & " and Path = '" & searchFolder & "'”，我最终放弃了，并解决了Windows资源管理器的搜索命令，只是手动执行。可能有一些方法可以做到我想要的，但我没有看到任何明显的东西，MSDN网站上的所有示例都是如此微不足道，以至于毫无价值。

EDIT嘿，当然，当我写这篇文章的时候，我又戳了一下，发现了我遗漏的东西:remove-item命令的-递归选项是错误的(如果你使用get-help remove-item -detailed就会显示出来)。

我一直在尝试“remove-item -filter '* .xyz' -recurse”，但它不起作用，所以我放弃了它。

事实证明你需要使用get-childitem -filter '*。Xyz ' -递归| remove-item

如果你喜欢shell脚本，你一定会爱上PowerShell!

从微软命令Shell (Ars Technica)的导游之旅开始。

我直到最近才开始认真地接触PowerShell。尽管在过去的7年里，我一直在一个几乎完全基于Windows的环境中工作，但我有Unix背景，我发现自己一直在努力将我在Windows上的交互体验“Unix化”。至少可以说，这令人沮丧。

将PowerShell与Bash、tcsh或zsh这样的东西进行比较是公平的，因为grep、sed、awk、find等实用程序严格来说都不是shell的一部分;然而，它们将永远是任何Unix环境的一部分。也就是说，像Select-String这样的PowerShell命令具有与grep非常相似的功能，并且被捆绑为PowerShell的核心模块…所以界限可能有点模糊。

我认为最关键的是文化，而事实上，各自的工具集将体现各自的文化:

Unix is a file-based, (in general, non Unicode) text-based culture. Configuration files are almost exclusively text files. Windows, on the other hand has always been far more structured in respect of configuration formats--configurations are generally kept in proprietary databases (e.g., the Windows registry) which require specialised tools for their management. The Unix administrative (and, for many years, development) interface has traditionally been the command line and the virtual terminal. Windows started off as a GUI and administrative functions have only recently started moving away from being exclusively GUI-based. We can expect the Unix experience on the command line to be a richer, more mature one given the significant lead it has on PowerShell, and my experience matches this. On this, in my experience: The Unix administrative experience is geared towards making things easy to do in a minimal amount of key strokes; this is probably as a result of the historical situation of having to administer a server over a slow 9600 baud dial-up connection. Now PowerShell does have aliases which go a long way to getting around the rather verbose Verb-Noun standard, but getting to know those aliases is a bit of a pain (anyone know of something better than: alias | where {$_.ResolvedCommandName -eq "<command>"}?). An example of the rich way in which history can be manipulated: iptables commands are often long-winded and repeating them with slight differences would be a pain if it weren't for just one of many neat features of history manipulation built into Bash, so inserting an iptables rule like the following: iptables -I camera-1-internet -s 192.168.0.50 -m state --state NEW -j ACCEPT a second time for another camera ("camera-2"), is just a case of issuing: !!:s/-1-/-2-/:s/50/51 which means "perform the previous command, but substitute -1- with -2- and 50 with 51. The Unix experience is optimised for touch-typists; one can pretty much do everything without leaving the "home" position. For example, in Bash, using the Emacs key bindings (yes, Bash also supports vi bindings), cycling through the history is done using Ctrl-P and Ctrl-N whilst moving to the start and end of a line is done using Ctrl-A and Ctrl-E respectively ... and it definitely doesn't end there. Try even the simplest of navigation in the PowerShell console without moving from the home position and you're in trouble. Simple things like versatile paging (a la less) on Unix don't seem to be available out-of-the-box in PowerShell which is a little frustrating, and a rich editor experience doesn't exist either. Of course, one can always download third-party tools that will fill those gaps, but it sure would be nice if these things were just "there" like they are on pretty much any flavour of Unix. The Windows culture, at least in terms of system API's is largely driven by the supporting frameworks, viz., COM and .NET, both of-which are highly structured and object-based. On the other hand, access to Unix APIs has traditionally been through a file interface (/dev and /proc) or (non-object-oriented) C-style library calls. It's no surprise then that the scripting experiences match their respective OS paradigms. PowerShell is by nature structured (everything is an object) and Bash-and-friends file-based. The structured API which is at the disposal of a PowerShell programmer is vast (essentially matching the vastness of the existing set of standard COM and .NET interfaces).

简而言之，尽管PowerShell的脚本功能可以说比Bash更强大(特别是当您考虑到. net BCL的可用性时)，但交互体验明显较弱，特别是如果您从完全由键盘驱动、基于控制台的角度(就像许多unix用户一样)进行交互时。
