PowerShell is the must-have tool for system administrators. Jump-start your career, and your IT environment, by getting up and running with the latest version, PowerShell 7.PowerShell is a cross-platform task automation and configuration management framework, consisting of a command-line shell and scripting language. Unlike most shells, which accept and return text, PowerShell is built on top of the .NET Common Language Runtime (CLR), and accepts and returns .NET objects. This fundamental change brings entirely new tools and methods for automation.Unlike traditional command-line interfaces, PowerShell cmdlets are designed to deal with objects. An object is structured information that is more than just the string of characters appearing on the screen. Command output always carries extra information that you can use if you need it.If you’ve used text-processing tools to process data in the past, you’ll find that they behave differently when used in PowerShell. In most cases, you don’t need text-processing tools to extract specific information. You directly access portions of the data using standard PowerShell object syntax.PowerShell is rapidly becoming the solution that Operators turn to with its powerful combination of a scripting language, command line speed, and GUI tools (Graphical User Interface).
