countDirFileNameOccurances.js

const fs = require('fs');

if (process.argv.length <= 2) {
  console.log('Usage: ' + __filename + ' path/to/directory');
  process.exit(-1);
}

const path = process.argv[2];

fs.readdir(path, (err, items) => {
  if (err) {
    console.error(err);
    process.exit(-1);
  }
  console.log(items);

  for (var i = 0; i < items.length; i++) {
    console.log(items[i]);
  }
});
