It turns out that units(1) is not as horrible to use in scripts
as I initially thought. When the --terse flag is combined
with an appropriate output format (set via --output-format),
units(1) is actually capable of producing very nice results.
For example:
units -o %0.f -t '4 gigabytes' bytes
is is just going to print out the expected value of 4294967296.
There is no time to waste. People have to know about it.
I am adding an example for this at the top of the examples section
because this is what users are most likely looking for.

# $FreeBSD$ This is a program which I wrote as a clone of the UNIX 'units' command. I threw it together in a couple days, but it seems to work, with some restrictions. I have tested it under DOS with Borland C and Ultrix 4.2, and SunOS 4.1. This program differs from the unix units program in the following ways: it can gracefully handle exponents larger than 9 in output it uses 'e' to denote exponentiation in numbers prefixes are listed in the units file it tries both -s and -es plurals it allows use of * for multiply and ^ for exponentiation in the input the output format is somewhat different Adrian Mariano (adrian@cam.cornell.edu or mariano@geom.umn.edu)
