This wouldn't be the definitive answer if you have multiple perls (or multiple CGI.pm) on your system, but it's a start.

As for the same file, check for errors - your upload may be failing:

my $query = new CGI;
my $error  = $query->cgi_error;

 if ($error) {
               print $query->header(-status=>$error),
                      $query->start_html('Problems'),
                      $query->h2('Request not processed'),
                     $query->strong($error);
               exit 0;
 }

And I'm just assuming you have a typo in your posting ($file_name vs $name)

Hi again, The version of CGI i am using is 2.56. I tried the error suggestion (with: else { print "no error"}) on the end. When I submit the data.txt file it prints the contents of the old data.txt + no error. If i submit anything else nothing prints. This is driving me crazy!! p.s the $filename / $name thing wasn't a typo, but i can't see whats wrong with that!? ;-)

There's something very wrong with the $file_name / $name thing. Consider your snippet:

my $file_name = $2;
open (FILE, "$name") or die "unable to open file";

What is $name set to? Undef? Something else in your script (global $name?) On top of that I don't think doing a regex is really necessary (or would actually accomplish what you want).

Here's some code to demonstrate:

#!/usr/local/bin/perl -w

use CGI qw(:standard);

my $query = new CGI;


print $query->header;
print $query->start_html( -title => "CGI" );


if( $CGI::DISABLE_UPLOADS ) {
    print $query->h2( 'Cheezy - uploads disabled in CGI.pm ... try res
+etting' );
    $CGI::DISABLE_UPLOADS = 0;
} else {
    print $query->h2( 'Great ... uploads enabled in CGI.pm' );
}


my $file = $query->upload('file');

if( ! $file ) {
    print "No file uploaded.";
} else {

    $file =~ m/^.*(\\|\/)(.*)/;
    my $file_name = $2;

    print $query->h2( 'file_name' ), $file_name;

    print $query->h2( 'File name' ), $file;
    print $query->h2( 'File MIME type' ), $query->uploadInfo( $file )-
+>{'Content-Type' };
    print $query->h2( 'Ref $file' ), ref( $file );

    my $data;
    while( <$file> ) {
        $data .= $_;
        $length += length( $_ );
    }

    print $query->h2( 'Contents' );
    print $query->pre( $data ), $query->p;

    print $query->h2( 'File length' ), $length;
}

print $query->end_html;
