This module wraps the df -BK
command which shows the amount of disk space available on the file system that a given file is stored on. It returns the used size and total size of the file system in kilobytes.
const diskSpace = require('disk-space');
diskSpace('/' , function(error, data) {
console.log(data); // returns { usedSize: 20, totalSize: 30 } in Kilobytes
});
