You might try using nl to prepend line numbers, the +POS option to sort to skip the line numbers, uniq -s to remove the duplicate lines while ignoring the line numbers (maybe the -u command to sort will skip them with the +POS option, and you can skip uniq), sort again including line numbers to restore the original order, and cut to remove the line numbers. This could all be done in one BF pipeline. Disclaimer: I haven't actually tried this, but it should work.
