I have created a script that traverses a file system (starting at your currect working directory) and lists all files and directories it finds. I need a way to show when each node (file or directory) was processed.

My script:

#!/usr/bin/perl -w

use strict;
use Cwd;

# Perl script to traverse a given directory and print when each direct
+ory or file is discovered.
# This starts from the user's current working directory.

my $dir = cwd();
my $discovered = 0;
my $processed = 0;

chomp (my $current = `pwd`);

sub process {
  $dir = shift;

  foreach (<$dir/*>) {
    my $file = $_;
    $file =~ s/$current\///g;

    next if (-l $_);

    if (-f $_) {
      print "Filename: $file\nDiscovered: $discovered\nProcessed: $pro
+cessed\n\n";
    }

    if (-d $_) {
      print "Directory name: $file\nDiscovered: $discovered\nProcessed
+: $processed\n\n";
      process($_);
    }
  }
}

process($dir);

If I were to run this against the directory layout

example_dir {file_one.txt file_two.txt next_dir {file_three.txt}} (file_one.txt and file_two.txt are inside example_dir, and next_dir is inside example_dir... file_three is inside next_dir, sorry if it's not clear)

I need to output to look like:

Filename: file_one.txt
Discovered: 1
Processed: 2

Filename: file_two.txt
Discovered: 3
Processed: 4

Directory name: next_dir
Discovered: 5
Processed: 8

Filename: file_three.txt
Discovered: 6
Processed: 7

I'm trying to print when each node is discovered and processed in the stack. Can anyone help?
