na_dd - copy blocks of data
dd [ [if= file ] | [ din= disknum bin= blocknum ] ]
[ [of= file ] | [ dout= disknum bout= blocknum ] ]
count= number_of_blocks
dd copies the specified number of blocks from source to
destination. Source and destination may be specified as
either a file that is a fully qualified pathname, or as a
starting block on a disk. The parameter disknum may range
from zero to the maximum number reported by na_sysconfig
(1) -r. In the latter form of specifying source or destination,
both disknum and blocknum must be specified. If
the source is missing, input is taken from standard input;
if the destination is missing, output is sent to standard
output. If the number of blocks exceeds the size of the
file, copying stops upon reaching EOF.
