Thanks, merged with for f in ../btc_qa_assets/fuzz_seed_corpus_ps/*/ ; do export F=$(basename $f) && ./src/test/fuzz/$F -merge=1 ../btc_qa_assets/fuzz_seed_corpus/$F ../btc_qa_assets/fuzz_seed_corpus_ps/$F ; done

Very nice! Thanks!

Unsolicited shell advice: export is only needed if any of the child processes were to read F :)
