Perhaps.  Honestly, I've never paid enough attention to IFS to have any
confidence in doing anything other than leaving it alone.

Either `find ... -print0 | xargs -0 ...` or a quick Perl script.

    opendir my $DIR, '.' or die ".: $!\n";
    foreach my $file(grep { $_ ne '.' and $_ ne '..' } readdir $DIR) {
        system 'cp', '-p', $file, "$file.bak";
        # error checking omitted for now
    }
    closedir $DIR;

(I'm not arguing that Perl is the best or only language for this; it
just happens to be what I'm most familiar with.)
