Set-Item - Powershell 1.0 CmdLet

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.

Set-Item

Description
Change the value of an item

Usage


Options
-path string
       The path(s) to the items. Wildcards are permitted.
       Use a dot (.) to specify the current location. 
       Use the wildcard (*) to specify all items in the current location.

   -literalPath string
       Like Path above, only the value is used exactly as typed.
       No characters are interpreted as wildcards. If the path includes any
       escape characters then enclose the path in single quotation marks.

   -value Object
       A new value for the item.
		 
   -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.
        
   -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.

   -option ScopedItemOptions
       Possible values include None,ReadOnly,Constant,AllScope and Private.
       (only valid when used with the Alias or Function provider)

   -force
       Override restrictions that prevent the command from succeeding, apart
       from security settings. e.g. Force will create file path directories 
       or override a files read-only attribute, but will not change file permissions.

   -credential PSCredential
       Use a credential to validate access to the file. Credential represents
       a user-name, such as "User01" or "Domain01\User01", or a PSCredential
       object, such as the one retrieved by using the Get-Credential cmdlet.
       If you type a user name, you will be prompted for a password.
       This parameter is not supported by any PowerShell core cmdlets or providers.
 
   CommonParameters:
      -Verbose, -Debug, -ErrorAction, -ErrorVariable, -OutVariable.

Example(s)
Set the AllScope and ReadOnly options for the "prompt" function:

PS C:\>set-item -path function:prompt -options "AllScope,ReadOnly"

Change the value of the "UserRole" environment variable to "Administrator":

PS C:\>set-item -path env:UserRole -value Administrator
