that looks very plausible, but it doesn't actually work,
as awk doesn't coelesce short reads (it gets short
reads from the pipe)
i had a similar need some time back and used inferno's sh:

hi,
since i see many solutions, i thought i will add mine too (if you can
use inferno). attached please see the limbo program i wrote for this.
it has helped me many times: didnt have to come out with parameters
for dd commands which i used to use before for this kind of tasks.

sometimes what should work, doesn't. that (and the whitespace)
are why my version is longer.

good point. i should have worked that out!
it's not the first time i've been caught out by %g - perhaps
the default precision of %g should be 12 or more.
Isn't the sensible solution to add a "-b bytes" option to split?

Just curious having not heard of split before, what's the purpose of
it as-is? :)

split(1) is pretty informative. in Þe auncien[t] dais, it was sometimes hard
to send big files by email or fit them on floppies or 9 track tapes.
rchistory(1) shows i haven't used it once in the last 5 years.

Do you mean what's it's use? I'm no unix (or Plan 9) elder, but I think it's a
file-based implementation of what some text editors call folding.
Not a trivial function. Be
