If you take a look at the C/POSIX collation sequence, you'll see that the sequences A-F and a-f both sort after 0-9 in the POSIX/C locale. So long as the hex numbers do not mix case and are of the same length, the string collation sequence is congruent to a hex digits sequence.
If you have a list of hex numbers, you can decorate them with a column of zero-padded, case-folded numbers, sort on that column, then output the original numbers.
i have been trying to understand this chapter titled "Searching for Files and Text" for a few weeks now.
unfortunately, this chapter is one of those things, that no matter how hard you try and how long you try for, you are incapable of understanding (at least in my case)

It seems our administrators had installed the version of the "sort" command not having the -M option. Does anyone have the source code for this routine?

I am going through the Unix Made Easy second edition book by John Muster. So far it's been very informative and I can tell it may be a bit out of date.
In one of the exercises it talks about the "sort" command and using it to sort column's of data etc. The "sort" command has changed a bit and... (1 Reply)

UNIUNMASK(1) General Commands Manual UNIUNMASK(1)NAME
uniunmask - XOR bits or substitute glyphs in a GNU Unifont file.
SYNOPSIS
uniunmask [-iinput_file] [-ooutput_file]
DESCRIPTION
uniunmask reads a GNU Unifont .hex file. As it reads the font file, it scans for code points matching entries in the "masks.hex" and "sub-
stitutes.hex" files. "masks.hex" and "substitutes.hex" are also in GNU Unifont .hex format, ordered by Unicode code point (the hexadecimal
number to the left of the colon on each line).
If a code point is encountered from "substitutes.hex", the input code point in the original .hex file is ignored (as is any entry with the
same code point in "masks.hex") and the glyph from "substitutes.hex" is written to the output file.
Otherwise, if a code point is encountered from "masks.hex", the input glyph in the original .hex file is XORed with the bits in the
"masks.hex" entry. The result of this XOR operation is written to the output file.
OPTIONS -i Specify the input file. The default is stdin.
-o Specify the output file. The default is stdout.
FILES
masks.hex, substitutes.hex, *.hex GNU Unifont font files

BUGS
No known real bugs exist, except that this software does not perform extensive error checking on its input files. If they're not in the
format of the original GNU Unifont hex file, all bets are off.
