Get-PSProvider

Gets information about the specified PowerShell provider.

Syntax

Get-PSProvider
   [[-PSProvider] <String[]>]
   [<CommonParameters>]

Description

The Get-PSProvider cmdlet gets the PowerShell providers in the current session. You can get a particular drive or all drives in the session.

PowerShell providers let you access a variety of data stores as though they were file system drives. For information about PowerShell providers, see about_Providers.

Examples

Example 1: Display a list of all available providers

PS C:\> Get-PSProvider

This command displays a list of all available PowerShell providers.

Example 2: Display a list of all PowerShell providers that begin with specified letters

PS C:\> Get-PSProvider f*, r* | Format-List

This command displays a list of all PowerShell providers with names that begin with the letter f or r.

Example 3: Find snap-ins or module that added providers to your session

PS C:\> Get-PSProvider | Format-Table name, module, pssnapin -auto

Name        Module       PSSnapIn
----        ------       --------
Test        TestModule
WSMan                    Microsoft.WSMan.Management
Alias                    Microsoft.PowerShell.Core
Environment              Microsoft.PowerShell.Core
FileSystem               Microsoft.PowerShell.Core
Function                 Microsoft.PowerShell.Core
Registry                 Microsoft.PowerShell.Core
Variable                 Microsoft.PowerShell.Core
Certificate              Microsoft.PowerShell.Security

PS C:\> Get-PSProvider | Where {$_.pssnapin -eq "Microsoft.PowerShell.Security"}

Name            Capabilities      Drives
----            ------------      ------
Certificate     ShouldProcess     {cert}

These commands find the PowerShell snap-ins or modules that added providers to your session. All PowerShell elements, including providers, originate in a snap-in or in a module.

These commands use the PSSnapin and Module properties of the ProviderInfo object that Get-PSProvider returns. The values of these properties contain the name of the snap-in or module that adds the provider.

The first command gets all of the providers in the session and formats them in a table with the values of their Name, Module, and PSSnapin properties.

The second command uses the Where-Object cmdlet to get the providers that come from the Microsoft.PowerShell.Security snap-in.

Example 4: Resolve the path of the Home property of the file system provider

PS C:\> Resolve-Path ~

Path
----
C:\Users\User01

PS C:\> (get-psprovider FileSystem).home
C:\Users\User01

This example shows that the tilde symbol (~) represents the value of the Home property of the FileSystem provider. The Home property value is optional, but for the FileSystem provider, it is defined as $env:homedrive$env:homepath or $home.
