Oh no! You forgot that the -h flag of the GNU coreutils sort package doesn't actually do what it claims to, and can't be fixed for various historical reasons (stay with me now don't fall asleep)!

       -h, --human-numeric-sort
              compare human readable numbers (e.g., 2K 1G)

If only there was a better way!

Hi, FREDDY MAYS here with another FUR-tastic invention. All your numbers, sorted just for you!

$ mv important_filenames.txt tests/data/README_example.txt
$ hns < tests/data/README_example.shuf.txt
data_1.txt
data_2.txt
data_3.txt
data_4.txt
data_5.txt
data_6.txt
data_7.txt

Wow!

But if you git pull in the next Unix epoch, you'll also get my super duper negative number-understanding version!

$ seq -10 10 | awk '{printf "data_%s.txt\n", $1}' | sort -h > tests/data/README_example2.shuf.txt

Before your numbers were sad and drab…

data_0.txt
data_-10.txt
data_10.txt
data_-1.txt
data_1.txt
data_-2.txt
data_2.txt
data_-3.txt
data_3.txt
data_-4.txt
data_4.txt
data_-5.txt
data_5.txt
data_-6.txt
data_6.txt
data_-7.txt
data_7.txt
data_-8.txt
data_8.txt
data_-9.txt
data_9.txt

But now they can be radically sequential! (Woah!)

$ hns < tests/data/README_example2.shuf.txt
data_-10.txt
data_-9.txt
data_-8.txt
data_-7.txt
data_-6.txt
data_-5.txt
data_-4.txt
data_-3.txt
data_-2.txt
data_-1.txt
data_0.txt
data_1.txt
data_2.txt
data_3.txt
data_4.txt
data_5.txt
data_6.txt
data_7.txt
data_8.txt
data_9.txt
data_10.txt

So simple to use! No command line options! Just standard in and standard out, one size fits all! (Really, Freddy?) (Yes!)

And it's not only for short files, oh no no no! It's written in Rust so you know it can handle even the largest data overflows, such as an entire randomly sorted Class A network!

$ time RUST_LOG=INFO target/release/hns < /tmp/0.0.0.0/8.shuf.txt > /dev/null

Sixteen million lines with four comparison points each sorted in under thirty seconds! And that's a Freddy Mays guarantee.
