DESCRIPTION

A "human numeric" sorting program — does what sort -h is supposed to do!

(That is to say, it does what you likely already thought or may've assumed GNU/BSD sort -h does.)

OPTIONS

-h, --help
        Print help information

-V, --version
        Print version information

EXAMPLES

• find . | hns

  Numerically sort the names of the files in the current directory.

• hns < <(dig peeweeharms.hk)

  Numerically sort the IP addresses in the output of dig.

LONG EXAMPLE

#!/bin/bash
# ①
seq 0 1000
    |
xargs -I{} bash -c "echo {{}} > {}"

# ②
seq 0 1000
    |
# ③
awk '{printf "mv %s topsecret_%s.json\n", $0, $0}'
    |
parallel

# ④
paste <(seq 0 1000) <(hns < <(echo topsecret_[[:digit:]]*.json))
    |
awk '{mv %s topsecret_%04d.json\n", $2, $1}' | parallel

Use as part of a pipeline to fix accidentally unzeropadded numbers 😄

• ① write some top secret JSON-format files as 0..=1000
• ② move them to .json file extensions
• ③ oops! forgot to zeropad!! managing these files will suck now 🙁
• ④ luckily we have hns!
