# DESCRIPTION:
    # based on https://gist.github.com/githubutilities/b5318d08a4b970d104f1
    # but not as failure-prone, ghetto, or manual
# BUGS: Slow as fuck
# JANK: I use gnu utilities because bsd userland is a barely-working plague,
    # but reversed tail is a bsd thing so we call it by path
