Re^2: Big problem in pattern matching

I changed my code, and it works pretty find.

#!/usr/bin/perl

use CGI;

my $cgi = new CGI;
print $cgi->header('text/html');

if (defined $cgi->param('ok')) {
    
    my $dir = 'C:\\inetpub\\wwwroot\\vortragsreihe_DEV\\';    
    my $book = $dir.'dir.txt';

    opendir(DIR, $dir) or die $!;
    open FILE, '>'.$book;

        while (my $file = readdir(DIR)) {
            if(-f $dir.$file){
            # Use a regular expression to ignore files beginning with 
+a period
            next if ($file =~ m/^\./);

            print FILE "C:\\inetpub\\wwwroot\\vortragsreihe_DEV\\$file
+\n";
            }
        }
close FILE;
closedir(DIR);

open (DATEI, '<' . 'C:\\inetpub\\wwwroot\\vortragsreihe_DEV\\dir.txt')
+ || die "Datei nicht gefunden $!";

    my @daten = <DATEI>; 
    close (DATEI); 
    chomp(@daten);    

        my $number = 0;
        my %params = $cgi->Vars;
        my $string = $cgi->param('string');
            
            foreach(@daten){
                print "finding -$string- in $daten[$number]\n"."</br>"
+;

                open(my $file,  "<",  "$daten[$number]")  or die "Can'
+t open the file: $!";
                my $num = 1;
                
                    while (<$file>) {
    
                         if (/$string/)
                         {     
                            if (my ($match) = /(\Q$string\E\S*)/) {
                            print "Matched '$string' in '$match' in li
+ne $num"."<br />";
                            }
                            # my $content =~ m/(\/$string\/[a-z]*)/g;
                            # print $content;
                            # print "found string -$string- in line $n
+um \n";
                            # print "<br>";
                         }
                         
                                
                $num++;
                     }
            $number++;
            }

}
else {

and do you know how to make it case insensitive? I tried to change it with `(/(\Q$string\E\S\i*)/)` but it does not work -,-	[reply] [d/l]
