Find-Command

Finds PowerShell commands in modules.

Syntax

    [[-Name] <String[]>]
    [-ModuleName <String>]
    [-MinimumVersion <String>]
    [-MaximumVersion <String>]
    [-RequiredVersion <String>]
    [-AllVersions]
    [-AllowPrerelease]

Description

The Find-Command cmdlet finds PowerShell commands such as cmdlets, aliases, functions, and workflows. Find-Command searches modules in registered repositories.

For each command found by Find-Command, a PSGetCommandInfo object is returned. The PSGetCommandInfo object can be sent down the pipeline to the Install-Module cmdlet. Install-Module installs the module that contains the command.

Examples

Example 1: Find all commands in a specified repository

The Find-Command cmdlet searches a registered repository for modules.

Find-Command -Repository PSGallery | Select-Object -First 10

Name                                Version    ModuleName          Repository
----                                -------    ----------          ----------
Disable-AzureRmDataCollection       5.8.3      AzureRM.profile     PSGallery
Disable-AzureRmContextAutosave      5.8.3      AzureRM.profile     PSGallery
Enable-AzureRmDataCollection        5.8.3      AzureRM.profile     PSGallery
Enable-AzureRmContextAutosave       5.8.3      AzureRM.profile     PSGallery
Remove-AzureRmEnvironment           5.8.3      AzureRM.profile     PSGallery
Get-AzureRmEnvironment              5.8.3      AzureRM.profile     PSGallery
Set-AzureRmEnvironment              5.8.3      AzureRM.profile     PSGallery
Add-AzureRmEnvironment              5.8.3      AzureRM.profile     PSGallery
Get-AzureRmSubscription             5.8.3      AzureRM.profile     PSGallery
Connect-AzureRmAccount              5.8.3      AzureRM.profile     PSGallery

Find-Command uses the Repository parameter to specify a registered repository's name. The objects are sent down the pipeline. Select-Object receives the objects and uses the First parameter to display the first 10 results.

Example 2: Find a command by name

Find-Command can use the name of a command to locate the module in a repository. It's possible that a command name exists in multiple ModuleNames.

Find-Command -Repository PSGallery -Name Get-TargetResource

Name                  Version    ModuleName                      Repository
----                  -------    ----------                      ----------
Get-TargetResource    3.1.0.0    xPowerShellExecutionPolicy      PSGallery
Get-TargetResource    1.0.0      xInternetExplorerHomePage       PSGallery
Get-TargetResource    1.2.0.0    SystemLocaleDsc                 PSGallery

Find-Command uses the Repository parameter to search the PSGallery. The Name parameter specifies the command Get-TargetResource.

Example 3: Find commands by name and install the module

Find-Command can locate the command and module, then send the object to Install-Module. If a command is included in multiple modules, use the Find-Command cmdlets Module-Name parameter. Otherwise, modules might be installed that you didn't want to install.

PS> Find-Command -Name Get-TargetResource -Repository PSGallery -ModuleName SystemLocaleDsc |
    Install-Module

PS> Get-InstalledModule

Version   Name               Repository   Description
-------   ----               ----------   -----------
1.2.0.0   SystemLocaleDsc    PSGallery    This DSC Resource allows configuration of the Windows...

Find-Command uses the Name parameter to specify the command Get-TargetResource. The Repository parameter searches the PSGallery. The ModuleName parameter specifies the module you want to install, SystemLocaleDsc. The object is sent down the pipeline to Install-Module and the module is installed. After the installation finishes, you can use Get-InstalledModule to display the results.

Example 4: Find a command and save its module

PS> Find-Command -Name Invoke-ScriptAnalyzer -Repository PSGallery | Save-Module -Path C:\Test\Modules -Verbose

VERBOSE: Downloading 'https://www.powershellgallery.com/api/v2/package/PSScriptAnalyzer/1.18.0'.
VERBOSE: Completed downloading 'https://www.powershellgallery.com/api/v2/package/PSScriptAnalyzer/1.18.0'.
VERBOSE: Completed downloading 'PSScriptAnalyzer'.
VERBOSE: Module 'PSScriptAnalyzer' was saved successfully to path 'C:\Test\Modules\PSScriptAnalyzer\1.18.0'.

Find-Command uses the Name and Repository parameters to search for the command Invoke-ScriptAnalyzer in the PSGallery repository. The object is sent down the pipeline to Save-Module. The Path parameter determines the location to save the module. Verbose is an optional parameter, but displays status output in the PowerShell console. The verbose output is beneficial for troubleshooting.

As of April 2020, the PowerShell Gallery no longer supports Transport Layer Security (TLS) versions 1.0 and 1.1. If you are not using TLS 1.2 or higher, you will receive an error when trying to access the PowerShell Gallery. Use the following command to ensure you are using TLS 1.2:

[Net.ServicePointManager]::SecurityProtocol = [Net.SecurityProtocolType]::Tls12
