PowerShell Sort-object

The sort-object is the cmdlet of a PowerShell, which sorts the objects in an order based on the property values. We can sort the objects by single or multiple properties. The various properties use the hash tables to sort the objects in ascending or descending order.

Syntax

Parameters

-Stable

This parameter was introduced in PowerShell version 6.2.0. The sorted objects are distributed in the order in which they were received when the sort criteria are equal.

-Descending

This parameter is used to sort the objects in the descending order.

-Unique

This parameter is used in sort-object cmdlet to eliminate duplicates and returns only the unique members of the collection. This parameter is case-insensitive.

-InputObject

When this parameter is used, then the sort-object cmdlet receives only one object, which represents the collection.

-Property

This parameter specifies the name of a property that sort-object cmdlet uses to sort the objects. In this parameter, wildcard characters are accepted. If you do not specify a property in the cmdlet, then it sorts on the basis of default properties for an object type.

-Culture

This parameter specifies the cultural configuration, which is used to sort the objects.

-CaseSensitive

This parameter is used in this cmdlet to indicate that the sorts are case-sensitive. By default, they are case-insensitive.
