Hi.

Here are two other methods. The first uses msort, which allows fields to be specified from the right-hand side. The other uses a quickly written perl code, which reverses the characters on each line:

Code:

#!/usr/bin/env bash

# @(#) s1	Demonstrate collect by extension, msort, perl, sort
# msort home: http://freshmeat.net/projects/msort

pe() { for _i;do printf "%s" "$_i";done; printf "\n"; }
pl() { pe;pe "-----" ;pe "$*"; }
db() { ( printf " db, ";for _i;do printf "%s" "$_i";done;printf "\n" ) >&2 ; }
db() { : ; }
re() { perl -wn -e 'print scalar reverse;' $1; pe ; }
C=$HOME/bin/context && [ -f $C ] && $C msort perl sort

FILE=${1-data1}
pl " Input file $FILE:"
head $FILE

pl " Results with msort:"
msort -q --line -d"." --position=-1,-1 --position=1,1 $FILE

pl " Results with (perl) reverse, sort, reverse:"
re $FILE |
sort -t"." |
re |
tee f1

exit 0

producing:

Code:

% ./s1

Environment: LC_ALL = C, LANG = C
(Versions displayed with local utility "version")
OS, ker|rel, machine: Linux, 2.6.26-2-amd64, x86_64
Distribution        : Debian GNU/Linux 5.0.8 (lenny) 
bash GNU bash 3.2.39
msort 8.44
perl 5.10.0
sort (GNU coreutils) 6.10

-----
 Input file data1:
a.xml
a.doc
a.txt
a.jpg
b.xml
b.doc
b.txt
b.jpg
c.xml
c.doc

-----
 Results with msort:
a.doc
b.doc
c.doc
a.jpg
b.jpg
c.jpg
a.txt
b.txt
c.txt
a.xml
b.xml
c.xml

-----
 Results with (perl) reverse, sort, reverse:


a.doc
b.doc
c.doc
a.jpg
b.jpg
c.jpg
a.xml
b.xml
c.xml
a.txt
b.txt
c.txt

The perl function is not completely satisfactory, but perhaps someone will stop by with a suggestion to omit the extra newlines.

I haven't tried to install msort on Solaris, but there is a link on MSORT for it.

Best wishes ... cheers, drl
