说明
This cmdlet is only available on the Windows platform.
New-FileCatalog creates a Windows catalog file
for a set of folders and files. This catalog file contains hashes for all files in the provided
paths. Users can then distribute the catalog with their files so that users can validate whether any
changes have been made to the folders since catalog creation time.
Catalog versions 1 and 2 are supported. Version 1 uses the (deprecated) SHA1 hashing algorithm to create file hashes, and version 2 uses SHA256.
示例
Example 1: Create a file catalog for `Microsoft.PowerShell.Utility`
$newFileCatalogSplat = @{
Path = "$PSHOME\Modules\Microsoft.PowerShell.Utility"
CatalogFilePath = '\temp\Microsoft.PowerShell.Utility.cat'
CatalogVersion = 2.0
}
New-FileCatalog @newFileCatalogSplat
