Hi Monks ! I am a beginner looking for some help.
I have 2 directories, Source and Target and I would like to take every directory/file in Source dir that is not in Target dir and copy it over to Target dir. This should include sub dirs as well.
If dir/file from Source is already in Target, I would like to print its dir/file name.
So far I came up with the follwoing code, but it doesnt seem to be working.
Usage: perl mergeTrees.pl SourceDir TargetDir 
use strict;
use File::Find;
use File::Copy;
use Cwd;

my $Src = $ARGV[0];
my $Trg = $ARGV[1];
my $path = getcwd();

find (\&wanted, $Src);

sub wanted {
    opendir (DIR, "$path/$Trg") or die "cannot opendir $Trg";
    foreach my $file (readdir(DIR)) {
        if ($_ == $file) {
            print "File already in $Trg: $file\n";
        } else {
            copy("$_","$path/$Trg/$_");
            
        }
    }
    closedir (DIR);
}
