Hi.

You could use a non-standard collating sequence with a non-standard utility:
Code:
#!/usr/bin/env bash

# @(#) s1	Demonstrate msort custom collating sequence.
# http://billposer.org/Software/msort.html

# Utility functions: print-as-echo, print-line-with-visual-space, debug.
# export PATH="/usr/local/bin:/usr/bin:/bin"
pe() { for _i;do printf "%s" "$_i";done; printf "\n"; }
pl() { pe;pe "-----" ;pe "$*"; }
edges() { local _f _n _l;: ${1?"edges: need file"}; _f=$1;_l=$(wc -l $_f);
  head -${_n:=3} $_f ; pe "--- ( $_l: lines total )" ; tail -$_n $_f ; }
db() { ( printf " db, ";for _i;do printf "%s" "$_i";done;printf "\n" ) >&2 ; }
db() { : ; }
C=$HOME/bin/context && [ -f $C ] && $C msort

FILE=${1-data1}

pl " Input data file $FILE:"
cat $FILE

pl " Results, default collating sequence:"
msort -l -q -w $FILE

pl " Results, custom collating sequence:"
msort -l -q -w -s collating-sequence.txt $FILE

pl " Custom: collating-sequence.txt:"
cat collating-sequence.txt

exit 0

producing:
Code:
% ./s1

Environment: LC_ALL = C, LANG = C

The msort utility was in the Debian repository. See the web page noted in the script for a PDF of documentation and other details ... cheers, drl

Quote:
"Non-standard" extant tools often: are general, have the
simplest, most appropriate interface, and are convenient
alternatives in the context of equally useful, but
"non-standard", nonce (one-off) awk, perl, ruby scripts.
The knowledge that such tools exist can be of advantage for
solving future similar, but specifically different problems.

comm

comm(1) 						      General Commands Manual							   comm(1)

NAME

       comm - select or reject lines common to two sorted files

SYNOPSIS

       file1 file2

DESCRIPTION

       comm  reads  file1  and	file2, which should be ordered in increasing collating sequence (see sort(1) and Environment Variables below), and
       produces a three-column output:

	      Column 1:   Lines that appear only in file1,
	      Column 2:   Lines that appear only in file2,
	      Column 3:   Lines that appear in both files.

       If is used for file1 or file2, the standard input is used.

       Options 1, 2, or 3 suppress printing of the corresponding column.  Thus prints only the lines common to the two files; prints only lines in
       the first file but not in the second; does nothing useful.

EXTERNAL INFLUENCES

   Environment Variables
       determines the collating sequence expects from the input files.

       determines the language in which messages are displayed.

       If is not specified in the environment or is set to the empty string, the value of determines the language in which messages are displayed.
       If is not specified in the environment or is set to the empty string, the value of is used as a default.  If is not specified or is set	to
       the  empty  string,  a  default of ``C'' (see lang(5)) is used instead of If any internationalization variable contains an invalid setting,
       behaves as if all internationalization variables are set to ``C''.  See environ(5).

   International Code Set Support
       Single- and multi-byte character code sets are supported.

EXAMPLES

       The following examples assume that and have been ordered in the collating sequence defined by the or environment variable.

       Print all lines common to and (in other words, print column 3):

       Print all lines that appear in but not in (in other words, print column 1):

       Print all lines that appear in but not in (in other words, print column 2):
