The code works, I just know it can be improved... I just want to make sure I'm using "die" right, I've had issues before this version where the .tar files I am trying to move would disappear if something went wrong. And fyi- I can't use modules due to permissions when installing

#!/usr/bin/perl -w

use strict;
use warnings;


my @files = glob "*.*";
my @tar_files = glob '*.tar.gz'; # All the tar files in the curr dir.
my @jpg_files = glob '*.jpg'; # All the .jpg files in the curr dir.

unless (@files) {
    die "No files here. Exiting!\n";
}

for my $tar_file (@tar_files) {
    my ($path, $row) = $tar_file =~ m/^LC8(\d{3})(\d{3})\d+LGN\d\d\.ta
+r.gz$/xms;
    print "Found $tar_file, with path $path, and row $row\n";
    my $dir = "p${path}_r${row}";
    print "...so... dir is /$dir\n";
    #if (! -e $dir) {
        #print "$dir dir not found...";
