I've been trying to debug this (very) simple program all morning, and so I don't think I'm seeing it right anymore. I've looked through my books and nodes on PM, but I have not found anything that helps.

What this is supposed to do is reproduce the file structure in one directory (recursively), but instead of copying the files it creates new ones with the same name (all with the same content contained in $redirect_page). 

my $htdocs_dir = "/home/httpd/htdocs";
my $disabled_htdocs = "/home/httpd/htdocs_disable";

check_dir(".");

#takes: a directory name
sub check_dir {
    my $dir = shift;
    #defined $dir || $dir = "";
    my $path = "$htdocs_dir/$dir";
    opendir (DIR, $path) || die "Can't open $htdocs_dir/$dir: $!";
    while (defined (my $dir_file = readdir DIR)) {
        if (-d "$path/$dir_file") { 
            unless ($dir_file eq '.' || dir_file eq '..') {
    mkdir("$disabled_htdocs/$dir/$dir_file",0755);
                check_dir("$dir/$dir_file");
            }
        }
        elsif (-f "$path/$dir_file") { add_file("$dir/$dir_file") }
    }

#takes: file (with path)
sub add_file {
        my $file = shift;
        open FILE, ">$disabled_htdocs/$file" || die "Can't open $file:
+ $!";
        print FILE $redirect_page;
print "wrote $disabled_htdocs/$file\n";##!! this never prints
        close FILE;
        }

}

My problem is that it doesn't seem to be writing the files and only goes into one directory.

thanks, a very tired melguin.
