Why PowerShell is powerful

The Windows operating system and Office Office software were so excellent that Microsoft was not named Poweros and Poweroffice, but in the second year after the release of Monad (the predecessor of PowerShell) (2006), Microsoft has just released Windows PowerShell 1.0, and "shamelessly" named PowerShell, which is a bit too uncomfortable.

Today I have a little summary of why PowerShell is so powerful, based on my experience.

An unprecedented convenience

such as GB,MB,KB units in the storage calculation; 1 in the array declaration: N and subscript is the processing of-1, as well as some WYSIWYG, easy-to-understand verb + noun structure cmdlet.

Object oriented

Compared to the process, the object-oriented more convenient and easier to describe the real world, but also to catch up with the fashionable.

Tied up. NET this big tree

The so-called tree under the good shade, PowerShell tied to the. NET this rich, with the. NET Framework platform a powerful class library, almost everything is possible.

Powerful compatibility

Fully compatible with other calls on the Windows platform, such as executable files (EXE), batch bat, and VB script.

Platform-based scalability

Microsoft has the advantage that it prefers to be a platform when compared to applications. PowerShell has already become a platform, and in the second year of PowerShell's release, Microsoft's system Center Operations Manager and SharePoint provided components for that platform, later Active Directory, Hyper-V, Let alone the Windows azure,office 365. In addition to Microsoft, Amazon's Cloud platform management, Dell's Out-of-hand management, also provides PowerShell-based management components. PowerShell has become a standard, becoming a norm.
