Format-Custom

Format-Custom [[-Property] <Object[]>] [-Depth <Int32>] [-DisplayError] [-Expand {CoreOnly | EnumOnly | Both}][-Force] [-GroupBy <Object>] [-InputObject <PSObject>] [-ShowError] [-View <String>] [<CommonParameters>]

The Format-Custom cmdlet formats the output of a command as defined in an alternate view. Format-Custom is designed to display views that are not just tables or just lists. You can use the views defined in the *format.PS1XML files in the Windows PowerShell directory, or you can create your own views in new PS1XML files and use the Update-FormatData cmdlet to add them to Windows PowerShell.

Parameters

-Depth <Int32>

  • Default value is None
  • Accepts pipeline input False

Specifies the number of columns in the display.

-DisplayError [<SwitchParameter>]

  • Default value is False
  • Accepts pipeline input False

Indicates that this cmdlet displays errors at the command line. This parameter is rarely used, but can be used as a debugging aid when you are formatting expressions in a Format-Custom command, and the expressions do not appear to be working. The following shows an example of the results of adding the DisplayError parameter with an expression.

`PS > Get-Date | Format-Custom DayOfWeek,{ $_ / $null } -ShowError`

`DayOfWeek $_ / $null` `--------- ------------` `Wednesday #ERR`

-Expand <String>

  • Default value is None
  • Accepts pipeline input False

Specifies that this cmdlet formats the collection object, as well as the objects in the collection. This parameter is designed to format objects that support the ICollection (System.Collections) interface. The default value is EnumOnly. The acceptable values for this parameter are:

- EnumOnly. Displays the properties of the objects in the collection. - CoreOnly. Displays the properties of the collection object. - Both. Displays the properties of the collection object and the properties of objects in the collection.

-Force [<SwitchParameter>]

  • Default value is False
  • Accepts pipeline input False

Indicates that this cmdlet displays all of the error information. Use with the DisplayError or ShowError parameter. By default, when an error object is written to the error or display streams, only some of the error information is displayed.

-GroupBy <Object>

  • Default value is None
  • Accepts pipeline input False

Specifies that this cmdlet formats the output in groups based on a shared property or value. Enter an expression or a property of the output.

The value of the GroupBy parameter can be a new calculated property. To create a calculated, property, use a hash table. Valid keys are:

- Name (or Label) <string>

- Expression <string> or <script block>

- FormatString <string>

-InputObject <PSObject>

  • Default value is None
  • Accepts pipeline input ByValue

Specifies the objects to be formatted. Enter a variable that contains the objects or type a command or expression that gets the objects.

-Property <Object[]>

  • Default value is None
  • Accepts pipeline input False

Specifies the object properties that appear in the display and the order in which they appear. Wildcards are permitted.

If you omit this parameter, the properties that appear in the display depend on the object being displayed. The parameter name ( Property ) is optional. You cannot use the Property and View parameters in the same command.

The value of the Property parameter can be a new calculated property. To create a calculated property, use a hash table. Valid keys are:

- Expression <string> or <script block>

- Depth <int32>

-ShowError [<SwitchParameter>]

  • Default value is False
  • Accepts pipeline input False

Indicates that this cmdlet sends errors through the pipeline. This parameter is rarely used, but can be used as a debugging aid when you are formatting expressions in a Format-Custom command, and the expressions do not appear to be working. The following shows an example of the results of adding the ShowError parameter with an expression.

PS > Get-Date | Format-Custom DayOfWeek,{ $_ / $null } -ShowError DayOfWeek $_ / $null --------- ------------ Wednesday

Failed to evaluate expression " $_ / $null ". + CategoryInfo : InvalidArgument: (10/30/2013 2:28:07 PM:PSObject) [], RuntimeException + FullyQualifiedErrorId : mshExpressionError

-View <String>

  • Default value is None
  • Accepts pipeline input False

Specifies the name of an alternate format or view. If you omit this parameter, Format-Custom uses a default custom view. You cannot use the Property and View parameters in the same command.

<CommonParameters>

This cmdlet supports the common parameters: Verbose, Debug,ErrorAction, ErrorVariable, WarningAction, WarningVariable,OutBuffer, PipelineVariable, and OutVariable.

Inputs
System.Management.Automation.PSObject
You can pipe any object to Format-Custom .
Outputs
Microsoft.PowerShell.Commands.Internal.Format
Format-Custom returns the format objects that represent the display.
Examples
  1. Format output with a custom view: 
    PS C:\> Get-Command Start-Transcript | Format-Custom -View "MyView"

    This command formats information about the Start-Transcript cmdlet in the format defined by the MyView view, a custom view created by the user. To run this command successfully, you must first create a new PS1XML file, define the MyView view, and then use the Update-FormatData command to add the PS1XML file to Windows PowerShell.

  2. Format output with the default view: 
    PS C:\> Get-Process Winlogon | Format-Custom

    This command formats information about the Winlogon process in an alternate customized view. Because the command does not use the View parameter, Format-Custom uses a default custom view to format the data.

Additional Notes
 Format-Custom * is designed to display views that are not just tables or just lists. To display an alternate 
 table view, use Format-Table. To display an alternate list view, use Format-List.

 You can also refer to Format-Custom by its built-in alias, fc. For more information, see about_Aliases.

 The GroupBy parameter assumes that the objects are sorted. Before using Format-Custom to group the objects, 
 use Sort-Object to sort them.
