Sorts objects by property values.
Sort-Object [[-Property] <Object[]>] [-CaseSensitive] [-Culture <string>] [-Descending] [-InputObject <psobject>] [-Unique] [<CommonParameters>]
The Sort-Object cmdlet sorts objects in ascending or descending order based on the values of properties of the object.
You can specify a single property or multiple properties (for a multi-key sort), and you can select a case-sensitive or case-insensitive sort. Yo
u can also direct Sort-Object to display only the objects with a unique value for a particular property.

Description
-----------
This command displays the five processes on the computer with the greatest memory use based on the size of their working sets.
The command uses the Get-Process cmdlet to get a list of processes. It uses a pipeline operator (|) to send the results to the Sort-Object cmdlet
, which sorts the objects in working-set order.
Another pipeline operator sends the results to the Select-Object, which displays only the last five items in the list.

Description
-----------
This command displays the services on the computer in descending Status order and ascending DisplayName order.
The command uses the Get-Service cmdlet to get the services on the computer. It uses a pipeline operator (|) to send services to the Sort-Object
cmdlet.
To sort one property in ascending order and another property in descending order, the command uses a hash table for the value of the Property par
ameter. The hash table uses an Expression key to specify the property name and an Ascending or Descending key to specify the sort order.
The resulting display, which sorts the Status values in descending order, lists properties with a Status value of "Running" before those with a S
tatus value of "Stopped". When sorted in ascending order, "Stopped" appears before "Running", because Status is an enumerated property in which t
he value of "Stopped" (1) is less than the value of "Running" (4).
