This topic is already well covered. Please use the search box in the top right corner.

Personally, I watch my oil pressure gauge and wait for it to come up to normal (30 seconds or so). Usually I need a few minutes to arrange things in the car, buckle, plug in the phone etc anyway.
Then I drive gently until engine reaches operating temperature.
