I am having a problem checking the existance of a file. I have ran the code used to check for the file in a seperate test file and it works fine. For some reason when present in this script it doesn't execute the needed code, which makes me assume that the -e if returning 0. In my test file I simulated the code as exactly as possible with regards to nested ifs with a foreach and the method in which the filename is described (${save_dir}${filename}). Anyone see what I'm missing?
#!/usr/bin/perl -w
use strict;
use HTML::SimpleLinkExtor;
use LWP::Simple;
use Image::Grab;
my $save_dir = ">/home/dir/";
my $page = 'http://website.com/webpage.html';
my $link;
my $image;
my $counter = 0;
my $pic = Image::Grab->new();
my $html = get($page);
my $extor = HTML::SimpleLinkExtor->new();
$extor->parse($html);
my @page_links = $extor->links;
my @temp = split(/\//, $page);
pop(@temp);
my $page_dir = join('/', @temp) . "/";
@temp ="";
print "$page_dir\n";
foreach $link (@page_links) {
if ($link =~ /jpg$/) {
next if $link =~ /small.jpg$/;
print $link . "\n";
$counter++;
my @temp = split(/\//, $link);
my $filename = pop(@temp);
#Here is the suspect code
if (-e "${save_dir}${filename}") {
print "$filename exists, skipping file";
next;
}
print "Save Dir = ${save_dir}${filename}\n";
print "Image URL = ${page_dir}${link}\n";
$pic->url($page_dir . $link);
$pic->grab;
open(IMAGE, "${save_dir}${filename}") || die "$!";
print IMAGE $pic->image;
close IMAGE;
print "${counter}: Saved $link \n\n";
}
}
print "Finished!\n";

Nothing in the world can take the place of persistence. Talent will not; nothing is more common than unsuccessful men with talent. Genius will not; unrewarded genius is almost a proverb. Education will not; the world is full of educated failures. Persistence and determination alone are omnipotent.
