Get-FormatData

  • Reference
Module:
Microsoft.PowerShell.Utility

Gets the formatting data in the current session.

Syntax

Get-FormatData
   [[-TypeName] <String[]>]
   [-PowerShellVersion <Version>]
   [<CommonParameters>]

Description

The Get-FormatData cmdlet gets the formatting data in the current session.

The formatting data in the session includes formatting data from Format.ps1xml formatting files, such as those in the $PSHOME directory, formatting data for modules that you import into the session, and formatting data for commands that you import into your session by using the Import-PSSession cmdlet.

You can use this cmdlet to examine the formatting data. Then, you can use the Export-FormatData cmdlet to serialize the objects, convert them to XML, and save them in Format.ps1xml files.

For more information about formatting files in PowerShell, see about_Format.ps1xml.

Examples

Example 1: Get all formatting data

This example gets all the formatting data in the session.

Get-FormatData

Example 2: Get formatting data by type name

This example gets the formatting data items whose names begin with System.Management.Automation.Cmd.

Get-FormatData -TypeName 'System.Management.Automation.Cmd*'

Example 3: Examine a formatting data object

This example shows how to get a formatting data object and examine its properties.

$F = Get-FormatData -TypeName 'System.Management.Automation.Cmd*'
$F

TypeName        FormatViewDefinition
--------        --------------------
HelpInfoShort   {help , TableControl}

$F.FormatViewDefinition[0].control

Headers          : {System.Management.Automation.TableControlColumnHeader,
                   System.Management.Automation.TableControlColumnHeader,
                   System.Management.Automation.TableControlColumnHeader,
                   System.Management.Automation.TableControlColumnHeader}
Rows             : {System.Management.Automation.TableControlRow}
AutoSize         : False

$F.FormatViewDefinition[0].control.Headers

Example 4: Get formatting data and export it

This example shows how to use Get-FormatData and Export-FormatData to export the formatting data that is added by a module.

$A = Get-FormatData
Import-Module bitstransfer
$B = Get-FormatData
Compare-Object $A $B

InputObject                                                SideIndicator
-----------                                                -------------
Microsoft.BackgroundIntelligentTransfer.Management.BitsJob =>

Get-FormatData *bits* | Export-FormatData -FilePath c:\test\bits.format.ps1xml
Get-Content c:\test\bits.format.ps1xml

<?xml version="1.0" encoding="utf-8"?><Configuration><ViewDefinitions>
<View><Name>Microsoft.BackgroundIntelligentTransfer.Management.BitsJob</Name>
...

The first four commands use the Get-FormatData, Import-Module, and Compare-Object cmdlets to identify the format type that the BitsTransfer module adds to the session.

The fifth command uses the Get-FormatData cmdlet to get the format type that the BitsTransfer module adds. It uses a pipeline operator (|) to send the format type object to the Export-FormatData cmdlet, which converts it back to XML and saves it in the specified format.ps1xml file.

The final command shows an excerpt of the format.ps1xml file content.

Example 5: Get formatting data based on the specified version of PowerShell

This example shows how to use Get-FormatData to get format data for a specified TypeName and PowerShell version.

Get-FormatData -TypeName 'Microsoft.PowerShell.Utility.FileHash' -PowerShellVersion $PSVersionTable.PSVersion

TypeNames                               FormatViewDefinition
---------                               --------------------
{Microsoft.PowerShell.Utility.FileHash} {Microsoft.PowerShell.Utility.FileHash}
