-Use open source commands in Powershell
+在Powershell 中使用开源命令
 ======
 
-When you launch an application on an operating system, there are certain code libraries and utility applications that your OS needs to use for that app to run. Your OS knows how to find these libraries and utilities because it has a _system path,_ a map to common shared data that lots of apps need. Every OS has this, but users aren’t usually aware of it because they don’t usually need to care about it. However, when you start coding or using special network utilities or commands, you might care about your own PATH variable.
+当你在操作系统上启动应用程序时，操作系统需要使用某些代码库和实用程序来运行该应用程序。你的操作系统知道如何找到这些库和实用程序，因为它有一个_系统路径_，一个到许多应用程序都需要用到的公共共享数据的映射。所有操作系统都有这一点，但用户通常不会意识到这一点，因为他们通常不需要在意它。然而，当你需要编程或使用特殊的网络实用程序或命令时，你可能需要关心你自己的PATH变量配置。
 
-The PATH variable makes it so that you can save commands to a consistent location, and use them from anywhere on your system using the command prompt or the more powerful (and open source) [Powershell][1].
+PATH变量使你可以将命令保存到一致的位置，并使用命令提示符或更强大(也是开源的)[Powershell][1]从系统上的任何位置调用它们。
 
-For instance, say you want to install the open source application `pscp.exe`, a command-line interface to the famous PuTTY OpenSSH client on Windows. You can download it to your hard drive, but how does your command-line know that it exists? Well at first, it doesn’t:
+例如，假设你想安装开源应用程序“pscp.exe”，它是Windows上著名的PuTTY OpenSSH客户端的命令行界面。你可以将它下载到你的硬盘，但是你的命令行如何知道它的存在呢?实时一开始，它并不知道:
 
 ```
 PS> pscp
- pscp: The term 'pscp' is not recognized as the name of a cmdlet, script file, or operable program. 
- Check the spelling of the name, or if a path was included, verify that the path is correct and try again.
+ pscp: 命令“pscp”不能被识别为cmdlet、脚本文件或可操作程序的名称。检查名称的拼写，或者如果包含了路径，则检查路径是否正确，然后再试一次。
 ```
 
-If you’re using an open source command line, such as Powershell or [Cmder][2], you get a useful error hinting that this might be a problem with your path (or the lack thereof). Here’s how to solve that problem.
+如果你正在使用一个开源命令行，例如Powershell或[Cmder][2]，那么你将得到一个有用的错误提示，提示这可能是你的路径有问题(或没有问题)。下面是解决这个问题的方法。

-Many applications get automatically added to the system path during installation.
