Hello, kind monks. This has got to be a prime example of the TMTOWTDI-ishness of Perl, but I will ask for comments on what I came up with anyway (and what I came up with was inspired by something half-remembered that I read somewhere once ..):

I want to take a list of URLs and sort them on the filename (string sort, not numeric) but also must get rid of expected duplicates. So I am going for both uniqueness and sorted-ness. My solution, which works well enough, is this:

my %UHash;  my $lk; my $r;
 for ($itr=0; $itr < @Linked_pics; $itr++)    {
     $lk = substr( $Linked_pics[$itr], rindex( $Linked_pics[$itr],'/') +1 );
	 $UHash{$lk} = $Linked_pics[$itr];
 }
 @Linked_pics = map { $_ = $UHash{$_}; } (sort keys %UHash);

The array $Linked_pics is already loaded with entries going into this routine, of course. Can any of our esteemed Wise Ones see a bloat that ought to be corrected here?



THANKS,
