Cmdlets are usually implemented around resource operations. The four basic operations are CREATE, READ, UPDATE and DELETE. This set of operations is known as CRUD. Most of the cmdlets support CRUD which are respectively cmdlets that start with the New/Get/Set/Remove cmdlet verbs but they also may have additional operations.
You can READ objects by using Get-Patch cmdlet. See example below:
|Copy-Patch||This cmdlet initializes staging of patches.|
|Get-PatchBaseline||This cmdlet retrieves patch baselines.|
|New-PatchBaseline||This cmdlet creates a new patch baseline.|
|Set-PatchBaseline||This cmdlet modifies the properties of a patch baseline.|
|Sync-Patch||This cmdlet downloads new patches into the Update Manager repository.|
