From Jargon File (4.3.1, 29 Jun 2001) [jargon]:

  dd /dee-dee/ vt. [Unix: from IBM {JCL}] Equivalent to {cat} or {BLT}.
     Originally the name of a Unix copy command with special options suitable
     for block-oriented devices; it was often used in heavy-handed system
     maintenance, as in "Let's `dd' the root partition onto a tape, then use
     the boot PROM to load it back on to a new disk". The Unix `dd(1)' was
     designed with a weird, distinctly non-Unixy keyword option syntax
     reminiscent of IBM System/360 JCL (which had an elaborate DD `Dataset
     Definition' specification for I/O devices); though the command filled a
     need, the interface design was clearly a prank. The jargon usage is now
     very rare outside Unix sites and now nearly obsolete even there, as
     `dd(1)' has been {deprecated} for a long time (though it has no exact
     replacement). The term has been displaced by {BLT} or simple English
     `copy'.
