Hmm, looks like the original article was moved. So here's a repost.

If you want to do this in Perl, take a look at File::Tools. Specifically, the copydir function will do exactly what you need. If modules rub you wrong (though they really shouldn't), this might do for you:

#!/usr/local/bin/perl -w
use strict;
use Carp;
use File::Copy "cp";

# need two arguments
scalar @ARGV == 2
    or print("Usage: copy.pl <source_dir> <target_dir>"), exit;

# record the bases of the source and target
my ($source_dir, $target_dir) = @ARGV;
CopyDir($source_dir, $target_dir);

sub CopyDir {
    my ($source_dir, $target_dir) = @_;

     # read the source directory        
    opendir (DIR, $source_dir) or croak "Couldn't open $source_dir: $!
+";
    my @list = readdir(DIR);                               
    
    # get a list of directories
    my @dirs =  grep {!/^\./ && -d "$source_dir/$_"} @list;
                                                 
    # get a list of real files                                        
+        
    my @files = grep {-f "$source_dir/$_"} @list;
    
    # create the target if necessary
    (!-e $target_dir and !-d $target_dir and mkdir $target_dir) 
        or croak "Couldn't mkdir $target_dir: $!";
    
    # recursively copy subdirectories
    map CopyDir("$source_dir/$_", "$target_dir/$_"), @dirs;
    
    # copy real files last
    map cp("$source_dir/$_", "$target_dir/$_"), @files;
}
