The “Select-Object” cmdlet selects the objects and properties specified by the user from a group of objects or an array. While the “-ExpandProperty” cmdlet works as a switch for the “Select-Object” property, as it details the selected property or an object from an array. Moreover, it can select objects from a specific position in an array.
