Minecraft 1.8 - /Clone Commamd

The /clone command is used to copy a region of blocks to another location. It takes 3 sets of coordinates, and optionally a mode which can also have additional arguments.

This is the full syntax:

/clone <x1> <y1> <z1> <x2> <y2> <z2> <x> <y> <z> [mode] [mode2] [TileName]

The first two coordinate sets (<x1> <y1> <z1> and <x2> <y2> <z2>) are opposite corners of a cuboid for the source region, as such:

You should mouse over the block and use the "Looking At" coordinates, or press [Tab], to get the coordinates of a block.

The third coordinate set is used as a place to clone the region to, the destination region. Note that the blocks will go in all 3 positive directions from this point, so you want to specify the lowest northwestern block like this:

The [mode] argument can be filtered, masked, or replace. replace is default and will overwrite all blocks in the destination region with those that are being cloned. masked is similar, but will not overwrite blocks in the destination with air. filtered will only clone the block that you specify in [TileName].

By default the command will give an error if the source and destination regions overlap to prevent glitches and strange inconsistencies; having [mode2] as force will prevent this, and attempt to do it anyway. Setting [mode2] to move automatically fills the source region with air, to give the effect of moving rather than copying. Finally, normal is the default for [mode2]. You will only need to specify normal if you need to give a [TileName] for a filtered [mode].
