Tengo un error en un script que hasta hace poco funcionaba y ahora al ejecutarlo salen errores...
El script baja una imagen de una web y la guarda en un directorio local. He aprovechado el script del tutorial
Descargar imágenes vía HTTP.
El script modificado y que antes me funcionaba es este:

- #!/usr/bin/perl -w
- use strict;
- use File::Path;
- use File::Copy;
- use lib '/usr/lib/perl5/site_perl/5.8.8';
- use Image::Grab qw(grab);
- my $img = new Image::Grab;
- $img->url('http://webcam.cnelbalis.com/record/current.jpg');
- $img->grab;
- if($img->image){
- # Salvamos la imagen al disco
- open(IMAGEN, ">img_Balis.jpg") || die"No se pudo crear archivo: $!";
- binmode IMAGEN; #para derivados de MSDOS.
- print IMAGEN $img->image;
- close IMAGEN;
- # ÉXITO
- print "La imagen fue descargada con éxito\n";
- }else{
- print "NO EXISTE LA IMAGEN\n";
- }
- exit(1);

El siguiente script sí que baja bien la imagen, pero igualmente me gustaría saber el motivo por el cual el anterior script ha dejado de funcionar...
Using perl Syntax Highlighting
- #!/usr/bin/perl
- my $url = 'http://webcam.cnelbalis.com/record/current.jpg';
- use LWP::Simple;
- my $content = get $url;
- open XX,">img_Balis.jpg";
- print XX $content;
- binmode(XX);
- close XX;
- print "content-type: text/plain\n\nDONE";
- exit;
