cmdletlisäosia

Cmdlet-lisäosat, often referred to as PowerShell snap-ins or modules, are extensions that add cmdlets and other functionalities to the Windows PowerShell environment. They are essential for expanding the capabilities of PowerShell beyond its core commands, allowing administrators and developers to manage a wider range of systems and services. Historically, these were often implemented as snap-ins, which were .NET assemblies that registered themselves with PowerShell. More recently, the concept has evolved into PowerShell modules, which are typically .psm1 files containing scripts and functions, or .dll files that can be loaded dynamically.

These add-ons can provide cmdlets for managing specific Microsoft products, such as Active Directory, Exchange Server, or SQL Server. They can also offer cmdlets for third-party applications, hardware devices, or custom automation tasks. Installing a cmdlet-lisäosa makes its cmdlets available in the PowerShell session, allowing users to discover and utilize the new commands through standard PowerShell cmdlets like Get-Command and Get-Help. The modular approach to cmdlet extensions promotes better organization, easier deployment, and version control of PowerShell functionalities.
