Hi,
I would like to know the difference between command and facade design pattern.

Both design pattern essentially hides the sub-system complexity and provides a easy to use interface to the client.
I am confused how to differentiate.

I know the theoretical difference between command and facade design pattern(as per their definitions). I would like to understand it from a practical perspective so that I can apply it when there is a need.

They are very different.

Facade is used to hide internal structure and provided a simplified interface.
The command pattern is used to encapsulate actions which allow you to program undoable actions, task queue's etc..
