Get-CimClass (PowerShell 3.0+ )

Get a list of CIM classes in a specific namespace.

Syntax
      Get-CimClass [[-ClassName] String] [[-Namespace] String]  [-MethodName String] 
         [ [-ComputerName String[]] | -CimSession CimSession[] ]
           [-PropertyName String] [-QualifierName String]
              [-OperationTimeoutSec UInt32] [CommonParameters]
    
Key
   -CimSession CimSession[]
       The CIM session to use for this cmdlet. Enter a variable that contains the CIM session or a command 
       that creates or gets the CIM session, such as the New-CimSession or Get-CimSession cmdlets. For more 
       information, see about_CimSessions.
        
   -ClassName String
       The name of the CIM class for which to perform the operation. 
       NOTE: You can use tab completion to browse the list of classes, because wps_2 gets a list of classes from the 
       local WMI server to provide a list of class names.
        
   -ComputerName String[]
       The computer on which you want to run the CIM operation. You can specify a fully qualified domain name 
       (FQDN), a NetBIOS name, or an IP address.
        
       If you specify this parameter, the cmdlet creates a temporary session to the specified computer using the 
       WsMan protocol.If you do not specify this parameter, the cmdlet performs the operation on the local computer
       using Component Object Model (COM).

       If multiple operations are being performed on the same computer, using a CIM session gives better performance.
        
   -MethodName String
       Finds the classes that have a method matching this name.
       You can use wildcard characters with this parameter.

   -Namespace String
       Specifies the namespace for CIM operation. The default namespace is root/cimv2.
       NOTE: You can use tab completion to browse the list of namespaces, because wps_2 gets a list of namespaces
       from the local WMI server to provide the list of namespaces.
 
   -OperationTimeoutSec UInt32
       Specifies the amount of time that the cmdlet waits for a response from the computer.
        
       By default, the value of this parameter is 0, which means that the cmdlet uses the default timeout value for 
       the server.
        
       If the OperationTimeoutSec parameter is set to a value less than the robust connection retry timeout of 3 
       minutes, network failures that last more than the value of the OperationTimeoutSec parameter are not 
       recoverable, because the operation on the server times out before the client can reconnect.
       
   -PropertyName String[]
       Finds the classes which have a property matching this name.
       You can use wildcard characters with this parameter.
       
   -QualifierName String
       Filters the classes by class level qualifier name. You can use wildcard characters with this parameter.
       
   CommonParameters:
       -Verbose, -Debug, -ErrorAction, -ErrorVariable, -WarningAction, -WarningVariable,
       -OutBuffer, PipelineVariable -OutVariable.

Standard Alias for Get-CIMClass: gcls

Examples

The CIM classes available will vary according to your operating system.
Get all the class definitions under the namespace root/cimv2:

PS C:\> Get-CimClass

List all the classes involding discs:
PS C:\> Get-cimclass -List | Where cimClassName -like "*disk*"
or
PS C:\> Get-CimClass -ClassName *disk*

Get the classes with a specific method name:

PS> Get-CimClass –ClassName Win32* -MethodName Term*

Get the classes with a specific property name:

PS C:\> Get-CimClass –ClassName Win32* -PropertyName Handle

Get the classes with a specific qualifier name,
get classes that start with the name Win32, contain the word Disk in their names and have the specified qualifier 'Association':

PS C:\> Get-CimClass –ClassName Win32*Disk* -QualifierName Association

Get the class definitions from a specific namespace:

PS C:\> Get-CimClass -Namespace root/standardCimv2 -ClassName *Net*

Get the class definitions from a remote server:

PS C:\> Get-CimClass -ClassName *disk* -ComputerName Server64, Server65

Get the classes by using a CIM session:

PS C:\> $session = New-CimSession -ComputerName Server64, Server65
PS C:\> Get-CimClass -ClassName *disk* -CimSession $session

This set of commands creates a session with multiple computers and stores it into a variable $session using the New-CimSession cmdlet, and then gets the classes using the Get-CimClass cmdlet.
