Hi Monks I am new to Perl below is my script for comparing two text files and printing the difference. pattern matching is working for one occurrence. Could you please guide me where i am going wrong. Thanks for your kind help. 

#!/usr/bin/perl
#use strict;
use warnings;
open(FILE,'>C:\\Aolvldbcomp\\Difference.txt');
my ($names, $data) =('LEAP_O.txt','VLDB_O.txt');

open (FILE1,$names) || die;
    open (FILE2,$data) || die; 
    my @leapStrings = <FILE1>; 
    chomp (@leapStrings); 
    close(FILE1);
    
    my @vldbStrings = <FILE2>; 
    chomp (@vldbStrings); 
    close(FILE2);
    
        
    for my $leapString (@leapStrings){
        print FILE "$leapString";
        $leapString =~ s/^\s+//;
        $leapString =~ s/\s+$//;
        my $found = 0;
        for my $vldbString (@vldbStrings){

            $vldbString =~ s/^\s+//;
            $vldbString =~ s/\s+$//;
            $vldbString =~ s/Notification\s+(\d+)\s*$/N $1/g;
            $vldbString =~ s/Order/OR/g;
            
            
            if (($leapString) =~ m/$vldbString/i) {
               $found = 1;
               break;
            }
            
        }    
            
        if ($found) 
        {
            print FILE "\t FOUND IN VLDB =====\n";
        }
        else  
        {
            print FILE "\t NOT FOUND IN VLDB =====\n";
        }
    }

    close(FILE);
