Introduction
In this module, you'll learn how to filter objects out of the pipeline by using the Where-Object cmdlet to specify various criteria. This differs from the ability of Select-Object to select several objects from a collection because it provides more flexibility. With this new technique, you'll be able to keep or remove objects based on criteria of almost any complexity.
