The status output of dd is sent to stderr and [shell] only outputs the
stdout of the command.

You could redirect stderr to stdout by appending ' 2>&1' to your shell
command.

Or you could use [command] from Deken that has a separate outlet for
stderr. Contrary to [shell], [command] is actively maintained, has more
features and more fine grained control over the commands it executes.
It is meant as a replacement for [shell], [popen], [system] and co that
are all not actively maintained anymore and lack features.
