dd's syntax looks more like JCL than Unix.  Some think that was a prank.
It's been faithfully preserved through decades, and now we're even
cloning it.  Funny :)

[Qemu-devel] [PATCH RFC 0/1] Subcommand dd for qemu-img

[Reda Sallahi]

Hi,

I have a first patch that adds a minimal subcommand dd for qemu-img that
is similar to dd(1) so this is a work-in-progress.

So far it implements the bs and count options with of course the if and of
options (e.g. ./qemu-img dd if=foo.raw of=foo.qcow2 bs=128K count=10 -O qcow2).

There is no output with statistics for now so this acts like dd status=none.
