In place of print $log ("The threads is $tid Processing file, $file"); How to print the file names of the directory. 
#! perl -slw
use strict;
use threads;
use threads::shared;

our $N ||= 100;

our $t=5;
our $from=1;

our $filenames;

sub worker {
    my $tid = threads->tid;
   # my( $log, $semRef, $from, $to ) = @_;
  my( $log, $semRef, $from, $step, $to ) = @_;
  for (my $file = $from ; $file <= $to ; $file += $step) {
        lock $$semRef;
print $log ("The threads is $tid Processing file, $file");
        }

}

## A shared variable used as a semaphore for the log file resource
my $logSem :shared;
## Open the log file in the main thread
open my $log, ">myLog" or die $!;

my @threads = map{
  threads->create( \&worker, $log, \$logSem, $from + ($_ - 1), $t, $to
+) ;
} 1 .. $t ;
## Wait till they are done
$_->join for @threads;

## close the log
close $log;
