A script I wrote to convert files from IMG_XXXX.jpg to YYYY-MM-DD HH.MM.SS.jpg format, with proper duplicate file
require 'exifr'
files = Dir['*.jpg']
puts "Renaming #{files.count} files..."
new_file_names = Hash.new { |h,k| h[k] = [] }
files.each do |file|
exif = EXIFR::JPEG.new(file)
dt = exif.date_time_original
new_file_name = "#{dt.strftime('%Y-%m-%d %H.%M.%S')}"
