SYNOPSIS
/usr/games/ching [hexagram]
DESCRIPTION
The I Ching or Book of Changes is an ancient Chinese oracle
that has been in use for centuries as a source of wisdom and
advice.
The text of the oracle (as it is sometimes known) consists
of sixty-four hexagrams, each symbolized by a particular
arrangement of six straight (---) and broken (- -) lines.
These lines have values ranging from six through nine, with
the even values indicating the broken lines.
Each hexagram consists of two major sections. The Judgement
relates specifically to the matter at hand (For instance,
"It furthers one to have somewhere to go.") while the Image
describes the general attributes of the hexagram and how
they apply to one's own life ("Thus the superior man makes
himself strong and untiring.").
When any of the lines has the value six or nine, it is a
moving line; for any such line there is an appended judge-
ment which becomes significant. Furthermore, the moving
lines are inherently unstable and change into their oppo-
sites; a second hexagram (and thus an additional judgement)
is formed.
Normally, one consults the oracle by fixing the desired
question firmly in mind and then casting a set of changes
(lines) using yarrow-stalks or tossed coins. The resulting
hexagram will be the answer to the question.
Using an algorithm suggested by S. C. Johnson, this oracle
simply reads a question from the standard input (up to an
EOF) and hashes the individual characters in combination
with the time of day, process ID and any other magic numbers
which happen to be lying around the system. The resulting
value is used as the seed of a random number generator which
drives a simulated coin-toss divination. The answer is then
piped through nroff for formatting and will appear on the
standard output.
For those who wish to remain steadfast in the old tradi-
tions, the oracle will also accept the results of a personal
divination using, for example, coins. To do this, cast the
change and then type the resulting line values as an argu-
ment.
The impatient modern may prefer to settle for Chinese cook-
ies; try fortune(6).
