Read multiple files from folder in perl - perl

Question

I'm pretty new on perl and in need for some help, basically what I want is a program that reads all .txt files from a folder, doing the script and throw the output in a new folder with a new name. Everything works when I'm working with one file at the time, specifying the name of the file.. But I can't get it to work with all of the files in the folder. This is how far I've gotten.
#!/usr/bin/perl
use warnings;
use strict;
use Path::Class;
use autodie;
use File::Find;
my #now = localtime();
my $timeStamp = sprintf(
"%04d%02d%02d-%02d:%02d:%02d",
$now[5] + 1900,
$now[4] + 1,
$now[3], $now[2], $now[1], $now[0]); #A function that translates time
my %wordcount;
my $dir = "/home/smenk/.filfolder";
opendir(DIR, $dir) || die "Kan inte öppna $dir: $!";
my #files = grep { /txt/ } readdir(DIR);
closedir DIR;
my $new_dir = dir("/home/smenk/.result"); # Reads in the folder for save
my $new_file = $new_dir->file("$timeStamp.log"); # Reads in the new file timestamp variable
open my $fh, '<', $dir or die "Kunde inte öppna '$dir' $!";
open my $fhn, '>', $new_file or die "test '$new_file'";
foreach my $file (#files) {
open(FH, "/home/smenk/.filfolder/$file") || die "Unable to open $file - $!\n";
while (<FH>) {
}
close(FH);
}
while (my $line = <$fh>) {
foreach my $str (split /\s+/, $line) {
$wordcount{$str}++;
}
}
my #listing = (sort { $wordcount{$b} <=> $wordcount{$a} } keys %wordcount)[0 .. 9];
foreach my $str (#listing) {
my $output = $wordcount{$str} . " $str\n";
print $fhn $output;
}

Here is the simplest skeleton for the reading part using Path::Class (see also dir and file:
#!/usr/bin/perl
use warnings;
use strict;
use Path::Class;
my $src = dir("/home/smenk/.filfolder");
my #txt_files = grep /[.] txt\z/x, $src->children;
for my $txt_file ( #txt_files ) {
my $in = $txt_file->openr;
while (my $line = <$in>) {
print "OUT: $line";
}
}

You can also use another great module Path::Tiny, for dir/file operations and the Time::Piece for the date/time functions - like:
#!/usr/bin/env perl
use strict;
use warnings;
use Path::Tiny;
use Time::Piece;
my #txtfiles = path("/home/smenk/.filfolder")->children(qr/\.txt\z/);
my $outdir = path("home/smenk/.result");
$outdir->mkpath; #create the dir...
my $t = localtime;
my $outfile = $outdir->child($t->strftime("%Y%m%d-%H%M%S.txt"));
$outfile->touch;
my #outdata;
for my $infile (#txtfiles) {
my #lines = $infile->lines({chomp => 1});
#do something with lines and create the output #data
push #outdata, scalar #lines;
}
$outfile->append({truncate => 1}, map { "$_\n" } #outdata); #or spew;
