Compress a Folder/Directory via Perl5

tested in Windows, Mac OS X, Ubuntu16.04

#!/usr/bin/perl

#nultiple folder

	while(my $dir = shift){ #iterate the given list
		$dir =~ s|/$||;
        if (! -d $dir){
            push @haystack, $dir;
            #not a dir/folder, file hodoooor
            next
        }
	    sub haystack {
		    my $dir  = shift; # current dir name

				    if (-f "$_"){
						push @haystack, "$pat/$dir/$_";
					}
		            if (-d "$_") {
		                chmod 0755, "$_";
		                &haystack($_,"$pat/$dir");
                        # __SUB__ not work in windows
                        # no matter `use feature "current_sub"`
                        # or `use v5.16`
                        # run under perl v5.18.2
		            }
		        }
				chdir("..");
		    }
		}
		&haystack("$dir",'.');
    }
	$fname =~ s/[^A-Za-z0-9_\-\.;]+/_/g;
	$fname = substr($fname,0,15) if $fname > 14;
    # create a Archive::Tar object
    my $tar = Archive::Tar->new;
    # add files
	$tar->add_files(@haystack) or die "$!";
	# say STDERR "$_" for (@haystack);
	$tar->write("$fname.tbz",COMPRESS_BZIP);
	say "Saved to $fname.tbz";
}

So,

$ perl ./backupRenLab.pl font/
Saved to 1;font.tbz

font/
  |-- A/
      |-- A File 2.txt
      |-- AFile1.txt
  |-- B/
      |-- C/
          |-- CFile.txt
