Need Help??

in thread WGET equivalent

here is an example of my script with most of the details eliminated, still producing a permission denied error. Most mysterious!

#!/usr/local/bin/perl -w
use strict;
use CGI qw(:standard);
use CGI::Carp qw(warningsToBrowser fatalsToBrowser carpout);
use lib qw(/usr/lib/perl5/vendor_perl/5.8.6/LWP /usr/lib/perl5/vendor_
+perl/5.8.6
/ /usr/lib/perl5/vendor_perl/5.8.6/LWP/UserAgent.pm);
use LWP::UserAgent;


my $ua = LWP::UserAgent->new;
$ua->timeout(10);
$ua->agent('Mozilla/5.0');


my $current_page = "http://www.perlmonks.org";

my $response = $ua->get($current_page);
my $data = $response->content if($response->is_success) or die "not su
+ccessful $!\n";

if($data){
  print "page: $current_page\n$data\ndone", length($data);
}
else
  {
    print "no data\n";
  }

Your script works for me. BTW the `use lib ...` line looks like cargo cult programming - you don't know what it means, but write it nevertheless in the hope that it will help. With `use lib @list` you specify directories in which perl searches for modules. The last entry doesn't look a like a directory at all, so remove it. And it's somewhat unusual to have modules in `/`, so that probably isn't needed as well.	[reply] [d/l] [select]

Not mysterious. LWP::UserAgent does not set `$!`. The "`permission denied`" message you're seeing is just an artifact of $! having some value resulting from some system call. I recommend using `$response->as_string()` to inspect what you get back, and `die $response->status_line;` [download] (as the documentation of HTTP::Response suggests).	[reply] [d/l] [select]
