If you want a demonstration of this fact, on a Linux filesystem, poke
around with 'find'. Or if you've got Path::Iterator::Rule installed:
perl -MPIR -E' $it = PIR->new->ite

Keys are files.
Values are file contents.

In my other message where I give an analogy to a "Folder" or
"Directory" in a file system.

If keeping the data ordering is important, use an array. Otherwise, use
a hash. :)

use strict;
use warnings;
my @array = qw{

As my files are sorted numerically I managed to do the following (it's

Afternoon all,
I have the following problem:
I have an array containing a list of non-unique strings. eg:
@array Contains:
11_
22_
33_
33_
33_
44_
44_

What I would like to do is number each element of the array to look as
follows:
11_1
22_1
33_1
19 matches
