说明

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 PowerShell provider that provides access to the data.

示例

Example 1: Open a file

This command opens the file aliasApr04.doc in Microsoft Office Word. In this case, opening in Word is the default action for .doc files.

Invoke-Item "C:\Test\aliasApr04.doc"

Example 2: Open all files of a specific type

This command opens all of the Microsoft Office Excel spreadsheets in the C:\Users\User1\Documents folder. Each spreadsheet is opened in a new instance of Excel. In this case, opening in Excel is the default action for .xls files.

Invoke-Item "C:\Users\User1\Documents\*.xls"

-Exclude

Specifies, as a string array, an item or items that this cmdlet excludes in the operation. The value of this parameter qualifies the Path parameter. Enter a path element or pattern, such as *.txt. Wildcard characters are permitted. The Exclude parameter is effective only when the command includes the contents of an item, such as C:\Windows\*, where the wildcard character specifies the contents of the C:\Windows directory.

-Filter

Specifies a filter to qualify the Path parameter. The FileSystem provider is the only installed PowerShell provider that supports the use of filters. You can find the syntax for the FileSystem filter language in about_Wildcards. Filters are more efficient than other parameters, because the provider applies them when the cmdlet gets the objects rather than having PowerShell filter the objects after they are retrieved.

-LiteralPath

Specifies a path to one or more locations. The value of LiteralPath is used exactly as it is typed. No characters are interpreted as wildcards. If the path includes escape characters, enclose it in single quotation marks. Single quotation marks tell PowerShell not to interpret any characters as escape sequences.

For more information, see about_Quoting_Rules.
