DESCRIPTION


The Update-FormatData cmdlet reloads the formatting data from formatting files into the current session. This cmdlet lets you update the formatting data without restarting
Windows PowerShell.


Without parameters, Update-FormatData reloads the formatting files that it loaded previously. You can use the parameters of Update-FormatData to add new formatting files to
the session.


Formatting files are text files in XML format with the format.ps1xml file name extension. The formatting data in the files defines the display of Microsoft .NET Framework
objects in the session.


When Windows PowerShell starts, it loads the format data from the formatting files in the Windows PowerShell installation directory ($pshome) into the session. You can use
Update-FormatData to reload the formatting data into the current session without restarting Windows PowerShell. This is useful when you have added or changed a formatting
file, but do not want to interrupt the session.


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

Examples


-------------------------- EXAMPLE 1 --------------------------

PS C:\>update-formatdata



This command reloads the formatting files that it loaded previously.










-------------------------- EXAMPLE 2 --------------------------

PS C:\>update-formatdata -appendpath trace.format.ps1xml, log.format.ps1xml



This command reloads the formatting files into the session, including two new files, Trace.format.ps1xml and Log.format.ps1xml.

Because the command uses the AppendPath parameter, the formatting data in the new files is loaded after the formatting data from the built-in files.

The AppendPath parameter is used because the new files contain formatting data for objects that are not referenced in the built-in files.










-------------------------- EXAMPLE 3 --------------------------

PS C:\>update-formatdata -prependPath c:\test\NewFiles.format.ps1xml

# Edit the NewFiles.format.ps1 file.

PS C:\>update-formatdata



This example shows how to reload a formatting file after you have edited it.

The first command adds the NewFiles.format.ps1xml file to the session. It uses the PrependPath parameter because the file contains formatting data for objects that are
referenced in the built-in files.

After adding the NewFiles.format.ps1xml file and testing it in these session, the author edits the file.

The second command uses the Update-FormatData cmdlet to reload the formatting files. Because the NewFiles.format.ps1xml file was previously loaded, Update-FormatData
automatically reloads it without using parameters.
