Set-Acl - PowerShell 1.0

Microsoft Windows PowerShell is a command-line shell and scripting tool based on the Microsoft .NET Framework. It is designed for system administrators, engineers and developers to control and automate the administration of Windows and applications.

More than hundred command-line tools (so called "cmdlets") can be used to perform system administration tasks and Windows Management Instrumentation (WMI). These cmdlets are easy to use, with standard naming conventions and common parameters, and standard tools for piping, sorting, filtering, and formatting data and objects.

-Path path
       Path to the item to be changed {accepts wildcards}

   -aclObject ObjectSecurity
       An ACL with the desired property values.

   -filter string
       A filter in the provider's format or language. 
       The exact syntax of the filter (wildcard support etc) depends on the provider.
       Filters are more efficient than -include/-exclude, because the provider
       applies the filter when retrieving the objects, rather than having 
       PowerShell filter the objects after they are retrieved.

   -include string
       Include only the specified items from the Path. e.g. "May*"
       this only works when the path includes a wildcard character.
   -exclude string
       Omit the specified items from the Path e.g. "*SS64*"
       this only works when the path includes a wildcard character.

       Pass the object created by Set-Acl through the pipeline.
       Describe what would happen if you executed the command without
       actually executing the command.

       Prompt for confirmation before executing the command.

      -Verbose, -Debug, -ErrorAction, -ErrorVariable, -OutVariable.

       Prompt for confirmation before executing the command.

Copy the security settings from Dog.txt to Cat.txt

PS C:\>$DogACL = get-acl c:\dog.txt
PS C:\>set-acl -path C:\cat.txt -AclObject $DogACL

Or the same thing with a pipeline:

PS C:\>get-acl c:\dog.txt | set-acl -path C:\cat.txt

Apply the same $DogACL to all the files in C:\Temp\ and all of its subdirectories:

PS C:\>get-childitem c:\temp -recurse -force | set-acl -aclobject $DogACL -whatif
