NAME
bones-info - display information about a Nethack bones file
SYNOPSIS
bones-info [-a | --auto] [-b | --big-endian] [--debug] [--help] [-x |
--hexadecimal] [-l | --little-endian] [-v | --verbose] [--version]
file...
DESCRIPTION
bones-info displays information about a Nethack bones file. By default
it shows what byte sex it used to read the file and the 4 version
numbers which constitute the feature set and platform for the Nethack
binary which generated it.
ENDIANNESS (aka BYTE SEX)
Normally bones-info reads the bones file in little endian order,
regardless of the byte sex of the current system, mostly because it was
originally written to help with diagnosing problems with hearse and
that’s the most useful behavior for that purpose. You can use the
--auto, --big-endian, and --little-endian switches to change this.
--auto is particularly useful (and appropriate) when using --verbose.
OPTIONS
-a, --auto
Try to guess the right byte sex (little endian or big endian) for
each input file. If there doesn’t seem to be a right choice,
bones-info will output a warning, set a non-zero exit status, and
move on to the next file.
-b, --big-endian
Read the bones files in big endian order, such as is used by Macs.
See also "--auto".
--debug
Turn debugging on.
--help
Show the usage message and die.
-x, --hexadecimal
Output numbers in hexadecimal form.
-l, --little-endian
Read the bones files in little endian order, such as is used by
Intel hardware. This is the default, I include it so that you
don’t have to check what the default is if you know you want it a
certain way.
-v, --verbose
Output more info about the bones file. This tries to decode the 4
version numbers. Its useful when you want to see what the
differences are between two sets of version numbers. You’d
normally want to use --auto when you use --verbose.
--version
Show the version number and exit.
EXAMPLES
Output the values as used by the hearse server:
$ bones-info *
bonD0.0 sex=l v1=1 v2=2 v3=3 v4=4
bonD0.4.gz sex=l v1=50593792 v2=10357958 v3=555422078 v4=2759955912
bonD0.8.Z sex=l v1=1027 v2=3322682880 v3=2115050273 v4=3365241252
bonD0.19 sex=l v1=50528512 v2=10357830 v3=555409789 v4=2558629316
bonM0.1 sex=l v1=50593792 v2=404622406 v3=555417981 v4=2759955916
bonM0.T sex=l v1=50593792 v2=1969222 v3=555417981 v4=2759955912
Output the real values as seen on the system which wrote the file (by
guessing the byte sex of the file):
$ bones-info --auto *
bones-info: can't intuit byte sex of bonD0.0
bonD0.4.gz sex=l v1=50593792 v2=10357958 v3=555422078 v4=2759955912
bonD0.8.Z sex=b v1=50593792 v2=1969350 v3=555422078 v4=2759955912
bonD0.19 sex=l v1=50528512 v2=10357830 v3=555409789 v4=2558629316
bonM0.1 sex=l v1=50593792 v2=404622406 v3=555417981 v4=2759955916
bonM0.T sex=l v1=50593792 v2=1969222 v3=555417981 v4=2759955912
zsh: exit 1 bones-info --auto *

BUGS
Unsigned longs are assumed to be 4 bytes.
The --auto byte sex detection isn’t robust.
It’d be nice to be provide --verbose output for bones files from older
versions.
