    Something like this:

    • Use seek() to get something like the last 4096 bytes of a file.
    • See how many newlines you have in those bytes. If you have n or more, then you’re done. If you have fewer, then read the previous 4096 bytes until you’re done.

    Not sure if there’s a built-in way to do this.
