Returns all Web applications that match the given criteria.
Get-SPWebApplication [[-Identity] <SPWebApplicationPipeBind>] [-AssignmentCollection <SPAssignmentCollection>] [-IncludeCentralAdministration <SwitchParameter>]
The Get-SPWebApplication cmdlet returns all Web applications that match the scope given by the Identity parameter. The Identity can be the name of the name, URL, or GUID of the Web application. If no Identity is specified, all Web applications are returned.
The Central Administration Web application is only returned if its exact identity is provided or the IncludeCentralAdministration flag is provided.
| Parameter | Required | Type | Description | ||
|---|---|---|---|---|---|
| Identity | Optional | Microsoft.SharePoint.PowerShell.SPWebApplicationPipeBind | Specifies the name, URL, or GUID of the Web application. The type must be a valid URL, in the form http://server_name; a GUID, in the form 1234-5678-9876-0987; or a valid name, in the form SPWebApplication – 1212. | ||
| AssignmentCollection | Optional | Microsoft.SharePoint.PowerShell.SPAssignmentCollection | Manages objects for the purpose of proper disposal. Use of objects, such as SPWeb or SPSite, can use large amounts of memory and use of these objects in Windows PowerShell scripts requires proper memory management. Using the SPAssignment object, you can assign objects to a variable and dispose of the objects after they are needed to free up memory. When SPWeb, SPSite, or SPSiteAdministration objects are used, the objects are automatically disposed of if an assignment collection or the Global parameter is not used.
| ||
| IncludeCentralAdministration | Optional | System.Management.Automation.SwitchParameter | Includes the Central Administration Web application in the collection of Web applications that can be returned. The IncludeCentral Administration parameter must still meet any other filters provided. |
