Just a bit of humor:
COMPUTER
ME
% cd troff
% file *
advp9prog: directory yes (old attempt at plan 9 programmer's
guide)
algoawk: directory
yes (awk book)
bentley.ms: troff -ms input yes (Bentley
paper)
bentley2.ms: Ascii text wtf?
(Bentley paper retry)
cod.ms: troff input why not -ms? (paper on calculator program
I'm writing)
cod.ms.part: Ascii file doesn't understand .ig and pic? (part of
cod.ms that doesn't belong yet)
forloop.ms: Ascii this is pic input (flowchart on how for loops
work in JavaScript)
jstut.ms: HTML file
very wrong (JavaScript tutorial)
luxidejavu.ms: troff input fine (ripped from p9port, -ms .FP with
DejaVu and Luxi Sans)
programming.ms: c program no one would dare put a program that big
into one file, stupid (new attempt at programming tutorial, you'll see
it when it's done)
school: directory
good (stuff for school)
% file advp9prog/*
adv9prog/ch1: Ascii wtf?
adv9prog/ch2: c program not again
adv9prog/dates: short Ascii all right (I date evereything for
record keeping purposes)
adv9prog/mkfile: short Ascii don't
you know about mk?
% file algoawk/*
algoawk/book_macros: Ascii ?
algoawk/ch1: Ascii text oh my gawd,
something different!
algoawk/colophon: Ascii ...
algoawk/dates: short Ascii good
algoawk/intro: Ascii no
algoawk/mkfile: Ascii still no mk...
algoawk/show: rc executable file right
% file school/*
... To save you the trouble, they're either directories or -
ms input, but either showing "directory" or "Ascii."
A full report of my troff directory and subdirectories is in /n/
sources/contrib/pietro/file.funny.
So that's only one file that is absolutely correct. It turns out that
the problem is file isn't reading the
.FP font
as a troff -ms macro line. In the books, they don't read enough lines
to see that there are more .PPs than there are #includes. Ah well.
And if you thought that was funny, look at the example of a file that
actually seeks to more than one line from UNIX in "The UNIX-HATERS
Handbook" (now a free PDF from its authors).
