I've written up this little script that will print a range of sequential URLs based on an input URL. The idea is to generate a list of files suitable for use with wget. I was just wondering if there were any obvious improvements I could make to the regexes I'm using to extract the pathnames (or a module to eliminate them entirely) or just general improvements that could be made to the script.

Any help is much appreciated. Thanks.

#!/usr/bin/perl

require 5.6.1;

use strict;
use warnings;

die "Usage: listseq.pl <url> [min] <max>\n" unless (@ARGV >= 2 and @AR
+GV <= 3);

# Retrieve the URL
my $extract = shift;

# Sort out the range of numbered files we should be getting
my $min;

if (@ARGV >= 2) {
  $min = shift;
} else {
  $min = 1;
}

my $max = shift;

# Separate the path from the filename and save both
$extract =~ /^(\S*\/)(\S*?)$/;
my ($filepath, $filename) = ($1, $2);

# Pull the filename and extension from the file; determine precision (
+1 vs 01)
$filename =~ /^(\S+?)(\d+)(\.\S+)$/;
my ($name, $numlength, $extension) = ($1, length($2), $3);

# Print the list of filenames
for (my $i = $min; $i <= $max; $i++) {
  print ($filepath, $name, (sprintf "%0${numlength}d", $i), $extension
+, "\n");
}
