Invoke-Item

Updated: April 21, 2010

Applies To: Windows PowerShell 2.0

Performs the default action on the specified item.

Syntax

Invoke-Item [-LiteralPath] <string[]> [-Credential <PSCredential>] [-Exclude <string[]>] [-Filter <string>] [-Include <string[]>] [-Confirm] [-WhatIf] [-UseTransaction] [<CommonParameters>]

Invoke-Item [-Path] <string[]> [-Credential <PSCredential>] [-Exclude <string[]>] [-Filter <string>] [-Include <string[]>] [-Confirm] [-WhatIf] [-UseTransaction] [<CommonParameters>]

Description

The Invoke-Item cmdlet performs the default action on the specified item. For example, it runs an executable file or opens a document file in the application associated with the document file type. The default action depends on the type of item and is determined by the Windows PowerShell provider that provides access to the data.

Parameters

-Credential <PSCredential>

Specifies a user account that has permission to perform this action. The default is the current user.

Type a user name, such as "User01" or "Domain01\User01", or enter a PSCredential object, such as one generated by the Get-Credential cmdlet. If you type a user name, you will be prompted for a password.

This parameter is not supported by any providers installed with Windows PowerShell.

-Filter <string>

Specifies a filter in the provider's format or language. The value of this parameter qualifies the Path parameter. The syntax of the filter, including the use of wildcards, depends on the provider.
