Me too. Doesn't even fork an extra process.

Speaking as one who predates "head" I'd had differed on this:-) (Well, at the
least started on systems that predated "head").
True, [t]csh users can't use read. But Bourne shell users can, and should.
While we're picking nits, if one must read for an extra command, "sed q" is
even shorter. I have never liked "head" myself; "tail" I understand - it's
hard to do otherwise. But a simple:
sed 12q
is the same as
head -12
and shorter and easier to type. And sed definitely predates head.
