Description

The Find-Module cmdlet finds modules in a repository that match the specified criteria. Find-Module returns a PSRepositoryItemInfo object for each module it finds. The objects can be sent down the pipeline to cmdlets such as Install-Module.

The first time Find-Module attempts to use a repository, you might be prompted to install updates. If the repository source is not registered with Register-PSRepository cmdlet, an error is returned.

Find-Module returns the newest version of a module if no parameters are used that limit the version. To get a repository's list of a module's versions, use the parameter AllVersions.

If the MinimumVersion parameter is specified, Find-Module returns the module's version that is equal to or greater than the minimum. If there is a newer version available in the repository, the newer version is returned.

If the MaximumVersion parameter is specified, Find-Module returns the newest version of the module that does not exceed the version specified.

If the RequiredVersion parameter is specified, Find-Module only returns the module version that is an exact match to the specified version. Find-Module searches through all available modules, because name conflicts between sources can occur.

The parameters that take module version numbers expect strings formatted as version numbers.

  • Standard version numbers have a format of x.y.z where x, y, and z are numbers
  • Prerelease versions have a format of x.y.z-<prerelease_label> where the <prerelease_label> is arbitrary string assigned to that release.

The following examples use the PowerShell Gallery as the only registered repository. Get-PSRepository displays the registered repositories. If you have multiple registered repositories, use the -Repository parameter to specify the repository's name.

Examples

Example 1: Find a module by name

This example finds a module in the default repository.

Find-Module -Name PowerShellGet

Version   Name              Repository           Description
-------   ----              ----------           -----------
2.1.0     PowerShellGet     PSGallery            PowerShell module with commands for discovering...

The Find-Module cmdlet uses the Name parameter to specify the PowerShellGet module.

Example 2: Find modules with similar names

This example uses the asterisk (*) wildcard to find modules with similar names.

Find-Module -Name PowerShell*

Version   Name                            Repository    Description
-------   ----                            ----------    -----------
0.4.0     powershell-yaml                 PSGallery     Powershell module for serializing and...
2.1.0     PowerShellGet                   PSGallery     PowerShell module with commands for...
1.9       Powershell.Helper.Extension     PSGallery     # Powershell.Helper.Extension...
3.1       PowerShellHumanizer             PSGallery     PowerShell Humanizer wraps Humanizer...
4.0       PowerShellISEModule             PSGallery     a module that adds capability to the ISE

The Find-Module cmdlet uses the Name parameter with the asterisk (*) wildcard to find all modules that contain PowerShell.

Example 3: Find a module by minimum version

This example searches for a module's minimum version. If the repository contains a newer version of the module, the newer version is returned.

Find-Module -Name PowerShellGet -MinimumVersion 1.6.5

Version   Name             Repository     Description
-------   ----             ----------     -----------
2.1.0     PowerShellGet    PSGallery      PowerShell module with commands for discovering...

The Find-Module cmdlet uses the Name parameter to specify the PowerShellGet module. The MinimumVersion specifies version 1.6.5. Find-Module returns PowerShellGet version 2.1.0 because it exceeds the minimum version and is the most current version.

Example 4: Find a module by specific version

This example shows how to install a specific prerelease version of a module. Prerelease versions have a format of <version_number>-<prerelease_label>.

Find-Module PSReadLine -AllowPrerelease -RequiredVersion 2.2.4-beta1

Version        Name             Repository       Description
-------        ----             ----------       -----------
2.2.4-beta1    PSReadLine       PSGallery        Great command line editing in the PowerS…

Example 5: Find a module in a specific repository

This example uses the Repository parameter to find a module in a specific repository.

Find-Module -Name PowerShellGet -Repository PSGallery

Version   Name             Repository     Description
-------   ----             ----------     -----------
2.1.0     PowerShellGet    PSGallery      PowerShell module with commands for discovering...

The Find-Module cmdlet uses the Name parameter to specify the PowerShellGet module. The Repository parameter specifies to search the PSGallery repository.

Example 6: Find a module in multiple repositories

This example uses the Register-PSRepository to specify a repository. Find-Module uses the repository to search for a module.

Register-PSRepository -Name MySource -SourceLocation https://www.myget.org/F/powershellgetdemo/
Find-Module -Name Contoso* -Repository PSGallery, MySource

Repository    Version   Name             Description
----------    -------   ----             -----------
PSGallery     2.0.0.0   ContosoServer    Cmdlets and DSC resources for managing Contoso Server...
MySource      1.2.0.0   ContosoClient    Cmdlets and DSC resources for managing Contoso Client...

The Register-PSRepository cmdlet registers a new repository. The Name parameter assigns the name MySource. The SourceLocation parameter specifies the repository's address.

The Find-Module cmdlet uses the Name parameter with the asterisk (*) wildcard to specify the Contoso module. The Repository parameter specifies to search two repositories, PSGallery and MySource.

Example 7: Find a module that contains a DSC resource

This command returns modules that contain DSC resources. The Includes parameter has four predefined functionalities that are used to search the repository. Use tab-complete to display the four functionalities supported by the Includes parameter.

Find-Module -Repository PSGallery -Includes DscResource

Version     Name                            Repository    Description
-------     ----                            ----------    -----------
2.7.0       Carbon                          PSGallery     Carbon is a PowerShell module...
8.5.0.0     xPSDesiredStateConfiguration    PSGallery     The xPSDesiredStateConfiguration module...
1.3.1       PackageManagement               PSGallery     PackageManagement (a.k.a. OneGet) is...

3.1.0.0     xPowerShellExecutionPolicy      PSGallery     This DSC resource can change the user...

The Find-Module cmdlet uses the Repository parameter to search the repository, PSGallery. The Includes parameter specifies DscResource, which is a functionality that the parameter can search for in the repository.

Example 8: Find a module with a filter

In this example, to find modules, a filter is used to search the repository.

For a NuGet-based repository, the Filter parameter searches through the name, description, and tags for the argument.

Find-Module -Filter AppDomain

Version    Name              Repository           Description
-------    ----              ----------           -----------
1.0.0.0  AppDomainConfig     PSGallery            Manipulate AppDomain configuration...
1.1.0    ClassExplorer       PSGallery            Quickly search the AppDomain for classes...

The Find-Module cmdlet uses the Filter parameter to search the repository for AppDomain.

Example 9: Find a module by tag

This example shows how to find modules by a tag. The CrescendoBuilt value is a tag that is automatically added to modules created using the Microsoft.PowerShell.Crescendo module.

Find-Module -Tag CrescendoBuilt

Version Name            Repository Description
------- ----            ---------- -----------

Important

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
