Get-DfsrFileHash
Gets a file hash.
Sintaxis
Parameter Set: Default
Get-DfsrFileHash [-Path] <String[]> [ <CommonParameters>]
Descripción detallada
The Get-DfsrFileHash cmdlet gets a hash value identical to the one computed by the DFS Replication service for the specified file or folder during normal replication. Use this cmdlet to determine if you correctly populated a content set, or if a file is in sync between replication partners.
Parámetros
-Path<String[]>
Specifies an array of paths to files or folders. You can use local paths, mapped drives, or UNC paths.

Ejemplos
Example 1: Get a file hash
This command uses the Get-DfsrFileHash cmdlet to retrieve the simulated marshaled hash of the file C:\Rf01\Drawing2.vsd.
PS C:\> Get-DfsrFileHash -Path "C:\Rf01\Drawing2.vsd"
Example 2: Retrieve the hash of a folder and its contents
This command uses the Get-DfsrFileHash cmdlet to retrieve the hash of a folder and the hashes for the individual files in the folder.
PS C:\> Get-DfsrFileHash -Path "C:\Rf01\*"
Example 3: Retrieve the hash of a folder and its contents using recursion
This command uses the Get-DfsrFileHash cmdlet to retrieve the hash of a folder and the hashes for the individual files in the folder. The command also uses the Get-ChildItem cmdlet to recursively find all files and folders in the path.
PS C:\> Get-DfsrFileHash -Path (Get-ChildItem -Path c:\Rf01 -Recurse).fullname
Example 4: Retrieve the hash of files with the *.png extension
This command uses the Get-DfsrFileHash cmdlet to retrieve the hash of all files with a *.png extension. The command searches the folder path recursively.
PS C:\> Get-DfsrFileHash -Path (Get-ChildItem -Path c:\Rf01 -Recurse -Filter *.png ).fullname
Example 5: Retrieve and compare file hashes between two replicated folders
This example retrieves and compares simulated file hashes for two replicated folders on different computers.
The first command maps a drive to the replicated folder on the first computer.
The second command uses the Get-DfsrFileHash cmdlet to retrieve the simulated file hashes for the contents of the folder. The command saves the output to a text file.
The third command deletes the mapped drive for the first computer.
The fourth command maps the same drive letter to the replicated folder on the second computer.
The fifth command uses the Get-DfsrFileHash cmdlet to retrieve the simulated file hashes for the contents of the folder. The command saves the output to a text file.
The sixth command deletes the mapped drive for the second computer.
The seventh command uses the Compare-Object cmdlet to compare the two output files and display the results. In this example, the Drawing2.png files differ.
PS C:\> net use x: \\Srv01\c$\Rf01
PS C:\> Get-DfsrFileHash x:\* | Out-File c:\Srv01.txt
PS C:\> net use x: /d
PS C:\> net use x: \\Srv02\e$\data
PS C:\> Get-DfsrFileHash x:\* | Out-File c:\Srv02.txt
PS C:\> net use x: /d
PS C:\> Compare-Object -ReferenceObject (Get-Content C:\Srv01.txt) -DifferenceObject (Get-Content C:\Srv02.txt) -IncludeEqual
