Scripting with PowerShell

PowerShell Overview

PowerShell was first introduced in 2008 as a scripting language for Windows Server. Over the years it has evolved to an open-source, cross platform solution that can be used on Windows, Linux and macOS.

PowerShell Shells

The Windows PowerShell Integrated Scripting Environment (ISE) is a script editor for Windows PowerShell that allows you to run commands and write, test, and debug scripts in a single graphical interface. In addition to the PowerShell ISE, PowerShell is also well-supported in Visual Studio Code with rich intellisense and advanced debugging features.

Core Concepts

Using the pipe operator in PowerShell you can easily perform complex operations in a single line of code. Format cmdlets can be used to change the default output of a command and the Out comdlets allow you to send data to a text file or grid.

Object Pipeline Processing

PowerShell contains a bunch of commands that allow you to manipulate your objects using the pipeline. These cmdlets will help you to filter, sort, group, ... any object.

• Where-Object
• Foreach-Object
• Select-Object
• Sort-Object
• Measure-Object
• Compare-Object
• Group-Object
• Tee-Object

Working with Objects

PowerShell works mostly with .NET objects but also provides full access to COM and WMI.

• Registry Keys and Values
• COM Objects
• WMI Objects - CIMCmdlets
• .NET Objects
• Static Classes

Extending PowerShell Functionality

A module is a set of related PowerShell functionalities, grouped together as a convenient unit (usually saved in a single directory). PowerShell Package Manager allows you to find, install and remove software all from within PowerShell from various repositories on the Internet.

PowerShell Security

The execution policy is part of the security strategy of PowerShell. It determines whether you can load configuration files and run scripts, and it determines which scripts, if any, must be digitally signed before they will run.

PowerShell Jobs

Jobs are long-running tasks that are executed in the background. You don't have to wait for the job to finish and can perform other tasks while the job is running. Once completed, the job output can be retrieved. Jobs can be executed on a remote system or they can be scheduled.
