good day dear monks

this is a question regarding a storing issue - the main part of a little mecha-script works well - i want to store the results in a directory - so that the gathered fiels do not mess up my machine... so here we go... with the outline and the question... look forward to hear from you

i need to have some thumbnails from websites but i tried to use wget - but that does not work for me, since i need some rendering functions what is needet: i have a list of 2,500 URLs, one on each line, saved in a file. Then i want a script - see it below - to open the file, read a line, then retrieve the website and save the image as a small thumbnail. well since i have a bunch of web-sites (2500) i have to make up my mind about the naming of the results.

So far so good, well i think i try something like this


use strict;
use warnings;

use WWW::Mechanize::Firefox;

my $mech = new WWW::Mechanize::Firefox();

open my $urls, '<', 'urls.txt' or die $!;

while (<$urls>) {
  chomp;
  next unless /^http/i;
  print "$_\n";
  $mech->get($_);
  my $png = $mech->content_as_png;
  my $name = $_;
  $name =~ s#^http://##i;
  $name =~ s#/##g;
  $name =~ s/\s+\z//;
  $name =~ s/\A\s+//;
  $name =~ s/^www\.//;
  $name .= ".png";
  open my $out, ">", $name or die $!;
  binmode $out;
  print $out $png;
  close $out;
  sleep 5;

}

Note: all is nice and runs well so far untill - yes untill i tried to create a special option: i wanted to force the script to do some storing of the results in a folder Well, what do you think about the idea of storing the results in a folder called images or so!?) is this doable? it would help alot since i get stored the results in a folder. And the many results do not mess the machine...

i run into some issues. tried to do it - to store it in a directory thusly:

should i do it like so....


open(my $out, '>', "path/$name")

To write a file whose name is contained in $name in the directory images, the correct syntax is

<br>
<br>

open(my $out, '>', "images/$name")
[download]

note - the directory called images is in the very same folder...

i get the results

  perl test_8.pl

Any opinions on the best path forward?
