xPSDesiredStateConfiguration

The xPSDesiredStateConfiguration module is a more recent, experimental version of the PSDesiredStateConfiguration module that ships in Windows as part of PowerShell 4.0.

The high quality, supported version of this module is available as PSDscResources.

This module is automatically tested using PowerShell 5.1 on servers running Windows 2012 R2 and Windows 2016, and is expected to work on other operating systems running PowerShell 5.1. While this module may work with PowerShell versions going back to PowerShell 4, there is no automatic testing performed for these versions, and thus no guarantee that the module will work as expected.

This project has adopted this code of conduct.

Parameters

• [String] Path (Key): The path to the archive file that should be expanded to or removed from the specified destination.
• [String] Destination (Key): The path where the specified archive file should be expanded to or removed from.

• [Boolean] Validate (Write): Specifies whether or not to validate that a file at the destination with the same name as a file in the archive actually matches that corresponding file in the archive by the specified checksum method. If the file does not match and Ensure is specified as Present and Force is not specified, the resource will throw an error that the file at the desintation cannot be overwritten. If the file does not match and Ensure is specified as Present and Force is specified, the file at the desintation will be overwritten.

An invalid argument exception will be thrown if Checksum is specified while Validate is specified as false. ModifiedDate will check that the LastWriteTime property of the file at the destination matches the LastWriteTime property of the file in the archive. CreatedDate will check that the CreationTime property of the file at the destination matches the CreationTime property of the file in the archive. SHA-1, SHA-256, and SHA-512 will check that the hash of the file at the destination by the specified SHA method matches the hash of the file in the archive by the specified SHA method.

• [System.Management.Automation.PSCredential] Credential (Write): The credential of a user account with permissions to access the specified archive path and destination if needed.
• [Boolean] Force (Write): Specifies whether or not any existing files or directories at the destination with the same name as a file or directory in the archive should be overwritten to match the file or directory in the archive. When this property is false, an error will be thrown if an item at the destination needs to be overwritten. The default value is false.
