Interactive Assistance System
PowerShell comes with an interactive help system that provides detailed information about cmdlets, parameters, and examples. This system is very useful for administrators and users to understand and use PowerShell commands quickly.
Get-Help Function to Quickly Understand Cmdlets
The Get-Help cmdlet allows you to access the documentation of the cmdlet or function directly from the PowerShell console. With this, you don’t have to rely on external references to understand cmdlets.
Get-Help Get-ProcessThis command will display information about the Get-Process cmdlet, including its description, parameters, and usage syntax.
You can also use the -Examples parameter to see a practical example of using cmdlets:
Get-Help Get-Process -ExamplesHow to Get Get-Process Cmdlet Details
If you need in-depth information about the parameters of a cmdlet such as Get-Process, you can use the -Detailed or -Full parameters to see the full details.
Get-Help Get-Process -DetailedIf you need very complete documentation, use:
Get-Help Get-Process -FullThe two commands above will provide a full description, including a description of the parameters, the inputs received, and the output generated.
How to Update Help with Update-Help to the Latest Version
PowerShell allows you to update your help files to keep them relevant to the latest cmdlets and features. This is especially important considering that PowerShell continues to evolve.
Update-HelpThis command will download and install the latest help files for all installed modules. Make sure your device is connected to the internet before running this command.
If you want to update the help for a specific module, use:
Update-Help -Module Microsoft.PowerShell.ManagementBy default, PowerShell only includes minimal help files to reduce the size of the installation. By running Update-Help, you can download the full documentation for the cmdlets and modules.
PowerShell Modules and Commands
PowerShell uses the module concept to group cmdlets and related functions in a single, structured package. Modules allow users to extend PowerShell functionality by adding custom cmdlets and scripts as needed.
Modules are collections of cmdlets, functions, variables, and configuration files that are used to extend PowerShell’s capabilities. Modules can contain cmdlets for specific tasks such as system management, networking, or third-party applications.
Each module can be imported into a PowerShell session by using the Import-Module command. This module can make it easy to manage various applications or administrative tasks without the need to rewrite complex scripts.
Module Source
Modules for PowerShell can come from a variety of sources:
1. Modul Bawaan Windows 11
Windows 11 comes with standard modules included to manage various system features, such as file management, networking, and services.
Examples of Windows 11’s built-in modules are the Microsoft.PowerShell.Management module, which provides cmdlets for managing processes and services, and the Microsoft.PowerShell.Utility which includes utility functions for data manipulation.
2. Modul dari PowerShell Gallery dan Komunitas
PowerShell Gallery is the official repository for PowerShell modules created by the community and developers. You can search for and install modules from the PowerShell Gallery using the Find-Module and Install-Module cmdlets.
Example for searching for and installing modules from the PowerShell Gallery:
Find-Module -Name Az -Repository PSGallery
Install-Module -Name Az -ForceModule Az is an example of a module used to manage Azure services using PowerShell.
3. Modul Kustom yang Dibuat oleh Pengguna
