EdwardG,
Do you mean something like this:
#!/usr/bin/perl
use strict;
use warnings;
my %name = map {chomp; $_ => undef} <DATA>;
for my $person ( keys %name ) {
my $p_case = $person;
$p_case =~ s/(\w+)/\u$1/g;
$name{$p_case} = delete $name{$person};
}
my $finished = 0;
while ( ! $finished ) {
my $update = 0;
for my $person ( keys %name ) {
my @shorter = split " " , $person;
$_ =~ s/(\w+)\w/$1/ for @shorter;
my $new_name = join " " , @shorter;
if ( ! exists $name{$new_name} ) {
$update = 1;
$name{$new_name} = delete $name{$person};
}
}
$finished = 1 if ! $update;
}
Cheers - L~R

Are you posting in the right place? Check out Where do I post X? to know for sure.

Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big>
<blockquote> <br /> <dd>
<dl> <dt> <em> <font>
<h1> <h2> <h3> <h4>
<h5> <h6> <hr /> <i>
<li> <nbsp> <ol> <p>
<small> <strike> <strong>
<sub> <sup> <table>
<td> <th> <tr> <tt>
<u> <ul>
-
Snippets of code should be wrapped in
<code> tags not
<pre> tags. In fact, <pre>
tags should generally be avoided. If they must
be used, extreme care should be
taken to ensure that their contents do not
have long lines (<70 chars), in order to prevent
horizontal scrolling (and possible janitor
intervention).

or How to display code and escape characters
are good places to start.
