Come to my brother in the console!

Many shortcuts have flown into the basket since the release of Windows 2008. People simply marveled at the new blue window, which the guys from Microsoft for some reason inserted into their new products. People who are sitting on blogs and know programming have begun to study this window.



As a result, people began to realize that Microsoft really developed something new and interesting.
And so, why do you need it? Basically, a program called PowerShell (hereinafter PS) is intended for administrators and programmers. It allows you to automate about 99% of all actions in the system. Using it, you can configure remote computers, start and restart services, and perform maintenance of most server applications. As it turned out, the possibilities of the program are amazing.

Of course, advanced users will find many ways to use this amazing blue window.

The purpose of this article is simple - to show you a small fraction of the PS capabilities and give you a conceptual understanding of the subject. In fact, there are a myriad of documentation on the subject, so I don’t want to cover everything. I will also acquaint you with a set of utilities that will allow you not to get out of PS in principle.


What is a PS? This is a command line interpreter. You enter the necessary commands, the result of their execution is displayed on the screen. It's simple. Everything has been like this since the days of the dos and the good old Unix.

There are two main differences from the predecessors, which qualitatively distinguish PS from other interpreters.

• Very good integration with the Microsoft .NET Framework. This gives you the opportunity to weave powerful programmer solutions into your teams and scripts.
• All values ​​returned to your terminal are objects with which you can work as with objects, and not just a set of strings. This allows you to create incredibly powerful software scripts.
