I am trying to add the filename to the end of each line in my files. I tried a few solutions but none seem to work and this is what I have. I am not sure what I am missing or what is wrong. 

#!/usr/bin/perl -w
use strict;
use warnings;
use Text::ParseWords;

opendir IN, 'Master';
my @in = grep { /\.txt$/ } readdir IN; # read all file names form dir 
+except names started with dot
closedir IN;

for my $in (@in) {
  open IN, '<', "Master/$in" || next;
  open OUT, '>', "Update/$in" || die "can't open file Update/$in";
my @file = @in
while (my $file = <IN>) {
    my $line = $_;
    $updateline = $line . $file;
    print OUT "$updateline";
    }
  close OUT;
  close IN;
}
