By: Brenton J.W. Blawat

Overview of this book

PowerShell scripts offer a handy way to automate various chores. Working with these scripts effectively can be a difficult task. This comprehensive guide starts from scratch and covers advanced-level topics to make you a PowerShell expert. The first module, PowerShell Fundamentals, begins with new features, installing PowerShell on Linux, working with parameters and objects, and also how you can work with .NET classes from within PowerShell. In the next module, you’ll see how to efficiently manage large amounts of data and interact with other services using PowerShell. You’ll be able to make the most of PowerShell’s powerful automation feature, where you will have different methods to parse and manipulate data, regular expressions, and WMI. After automation, you will enter the Extending PowerShell module, which covers topics such as asynchronous processing and, creating modules. The final step is to secure your PowerShell, so you will land in the last module, Securing and Debugging PowerShell, which covers PowerShell execution policies, error handling techniques, and testing. By the end of the book, you will be an expert in using the PowerShell language.

Preface

The Install-Module command


The Install-Module command installs or updates modules from the PowerShell Gallery or any other configured repository. By default, Install-Module adds modules to the path for AllUsers, C:\Program Files\WindowsPowerShell\Modules.

Note

Access rights Installing a module under the AllUsers scope requires a user account control administrator token (run as administrator).

For example, the posh-git module may be installed using either of the following two commands:

Find-Module posh-git | Install-Module 
Install-Module posh-git 

Modules may be installed under a user-specific path ($home\Documents\WindowsPowerShell\Modules) using the Scope parameter:

Find-Module carbon -Scope CurrentUser

If the most recent version of a module is already installed, the command ends without providing feedback. If a newer version is available that will be automatically installed alongside the original (in a folder named after the version if using PowerShell 5.0).
