Generates text files with random numbers of a particular size. Size is given in kb's as first parameter, defaults to 100.

kbtxtgenerator.js

const fs = require("fs");
const lineLength = 126;
const sizeInKb = process.argv[2] || 100;

let data = "";

for(var i = 0; i < sizeInKb * 1024; i++) {
    if (i && i % lineLength === 0) {
        data += "\n";
    } else {
        data += Math.floor(Math.random() * 10);
    }
}

fs.writeFileSync(`./${sizeInKb}kb.txt`, data);
