generate csv with hash ,path, name from directory

folder2csv.js

const fs = require('fs')
const crypto = require('crypto')

const path2hash = p => crypto.createHash('sha256').update(p).digest('base64')

const basedir = process.argv.length > 2 ? process.argv[2] : process.env.PWD

const printout = x => process.stdout.write(x)

let csv = '\"hash\"\t\"path\"\t\"name\"'
printout(csv)
printout('\n')

const stopAt = Infinity

const dig = function dig (path, deep = 0) {
  if (deep < stopAt) {
    const here = fs.readdirSync(path)
    const dirs = []
    here.forEach(e => {
      const twig = path + '/' + e
      if (fs.lstatSync(twig).isFile()) {
        printout('\"' + path2hash(twig) + '\"')
        printout('\t ')
        printout('\"' + path.slice(basedir.length) + '\"')
        printout('\t ')
        printout('\"' + e + '\"')
        printout('\n')
      } else {
        dirs.push(e)
      }
    })
    dirs.forEach(e => dig(path + '/' + e, deep + 1))
  }
}

dig(basedir)

how to use
