Description

The Get-ItemProperty cmdlet gets the properties of the specified items. For example, you can use this cmdlet to get the value of the LastAccessTime property of a file object. You can also use this cmdlet to view registry entries and their values.

Examples

Example 1: Get information about a specific directory

This command gets information about the C:\Windows directory.

Get-ItemProperty C:\Windows

Example 2: Get the properties of a specific file

This command gets the properties of the C:\Test\Weather.xls file. The result is piped to the Format-List cmdlet to display the output as a list.

Get-ItemProperty C:\Test\Weather.xls | Format-List

Example 3: Get the value name and data of a registry entry in a registry subkey

This command gets the value name and data of the ProgramFilesDir registry entry in the CurrentVersion registry subkey. The Path specifies the subkey and the Name parameter specifies the value name of the entry.

Get-ItemProperty -Path HKLM:\SOFTWARE\Microsoft\Windows\CurrentVersion -Name "ProgramFilesDir"

Note

This command requires that there is a PowerShell drive named HKLM: that is mapped to the HKEY_LOCAL_MACHINE hive of the registry.

A drive with that name and mapping is available in PowerShell by default. Alternatively, the path to this registry subkey can be specified by using the following alternative path that begins with the provider name followed by two colons:

Registry::HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion.

Example 4: Get the value names and data of registry entries in a registry key

This command gets the value names and data of the registry entries in the PowerShellEngine registry key. The results are shown in the following sample output.

Get-ItemProperty -Path HKLM:\SOFTWARE\Microsoft\PowerShell\1\PowerShellEngine

Parameters

-Credential

Note

This parameter is not supported by any providers installed with Windows PowerShell. To impersonate another user, or elevate your credentials when running this cmdlet, use Invoke-Command.

Type:PSCredential
Position:Named
Default value:Current user
Required:False
Accept pipeline input:True
Accept wildcard characters:False

-Exclude

Specifies, as a string array, an item or items that this cmdlet excludes in the operation. The value of this parameter qualifies the Path parameter. Enter a path element or pattern, such as *.txt. Wildcard characters are permitted. The Exclude parameter is effective only when the command includes the contents of an item, such as C:\Windows\*, where the wildcard character specifies the contents of the C:\Windows directory.

Type:String[]
Position:Named
Default value:None
Required:False
Accept pipeline input:False
Accept wildcard characters:True

-Filter

Specifies a filter to qualify the Path parameter. The FileSystem provider is the only installed PowerShell provider that supports the use of filters. You can find the syntax for the FileSystem filter language in about_Wildcards. Filters are more efficient than other parameters, because the provider applies them when the cmdlet gets the objects rather than having PowerShell filter the objects after they are retrieved.

Type:String
Position:Named
Default value:None
Required:False
Accept pipeline input:False
Accept wildcard characters:True

-Include

Specifies, as a string array, an item or items that this cmdlet includes in the operation. The value of this parameter qualifies the Path parameter. Enter a path element or pattern, such as *.txt. Wildcard characters are permitted. The Include parameter is effective only when the command includes the contents of an item, such as C:\Windows\*, where the wildcard character specifies the contents of the C:\Windows directory.

Type:String[]
Position:Named
Default value:None
Required:False
Accept pipeline input:False
Accept wildcard characters:True

-LiteralPath

Specifies the path to the current location of the property. The value of LiteralPath is used exactly as it is typed. No characters are interpreted as wildcards. If the path includes escape characters, enclose it in single quotation marks ('). Single quotation marks tell PowerShell not to interpret any characters as escape sequences.

For more information, see about_Quoting_Rules.

Type:String[]
Aliases:PSPath
Position:Named
Default value:None
Required:True
Accept pipeline input:True
Accept wildcard characters:False
