Short script to sort du -h output by size.

sort.js

let sizemap = {
	'': 0,
	K: 1,
	M: 2,
	G: 3
};

let data = '`du -h --maxdepth 1` output';

let files = data
	.split(/\n/)
	.map(line => line.split(/\s+/))
	.sort(([a], [b]) => {
		let match = /(\d+(?:\.\d+)?)([KMG]?)/;
		let [, an, au] = a.match(match);
		let [, bn, bu] = b.match(match);
		let ucmp = sizemap[au] - sizemap[bu];
		return ucmp || an - bn;
	});

files.map(([a, b]) => `${a}	${b}`).forEach(x => {
	console.log(x);
});
