what is the equivalent command for this one:

Why do you want to do this? – mgorven Oct 26 '12 at 2:21

How about the same one. If I am not grossly mistaken or can't remember things now (just woke up and still in sleep). it should be the same. The command you mentioned is the standard way to drop caches.
