Double Density [disks] (FDD)
From The Jargon File (version 4.4.7, 29 Dec 2003) :
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?.
