Looking at what you are trying to achieve, here is the code 
use Data::Dumper; 
open (HAN,'employee.pm');
 my $cont = <HAN>; # assume $cont = 'package Employee df df'; 
my %hash = (); 
while ( $cont =~ m/(\w+)/g )
{ $hash{$1}++;
 } 

print Dumper(\%hash); --------- output 
$VAR1 = { 
'Employee' => 1, 
'df' => 2, 
'package' => 1 };

it prints how many time each word occured ..
