Ⅰ. Why learn about PowerShell?

1.PowerShell Introduction

Microsoft GUI graphical interface, with its graceful interface, simple visual operation, configuration service only a few mouse to complete, encountered do not know the operation can see the icon, instructions to operate, very simple and easy to use.

Why, then, should we learn about PowerShell?

If you create a domain user as an example, it takes 5 minutes to create a domain user under the GUI interface, because there are a bunch of properties that need to be added, it takes 500 minutes to create 100 users. There is no way to improve the speed at which users are created.

Early VBScript was able to create scripts to solve some problems, but because Microsoft did not devote all of its heart to VBScript, the product had many shortcomings. For example: You can use a script network configuration, want to test the speed of the network, you need to find another way.

The emergence of PowerShell fills the void, not only the functionality of the complete management system, but also the automation of repetitive tasks and the work not supported under the GUI. PS also supports a large number of components, such as Exchange, SharePoint, Systemcenter, and so on.

Microsoft is still developing the GUI console, which is still a PowerShell command at the bottom.
