Summary

Modules are a vital part of PowerShell. Modules allow users to extend the commands available within PowerShell, allowing PowerShell to work with many different systems from many different vendors.

The commands explored in this chapter have demonstrated how to discover and use locally available modules along with the commands each module contains. The PowerShell Gallery has been introduced as a public repository of modules, extending PowerShell further still.

PowerShellGet has been a feature of PowerShell since PowerShell 3. With the release of PowerShellGet 3 on the horizon, we demonstrated its new commands and filtering capabilities.

SMB- and NuGet-based repositories were briefly introduced for those looking to establish private repositories for use within an organization. This allows administrators to create private repositories with curated content, reducing exposure to the unknown modules.

Snap-ins, an artifact of PowerShell 1 that is limited to Windows PowerShell, were very briefly demonstrated for the products where snap-ins remain important.

Chapter 3, Working with Objects in PowerShell, dives into the commands available to work with objects in PowerShell, including Where-Object and ForEach-Object.
