¿Cómo sobrescribir únicamente los metadatos (en concreto, los atributos de archivo de fecha) entre archivos que tienen el mismo contenido con los atributos más antiguos/más precisos?

He trabajado hasta el siguiente Ruby script para copiar los atributos de fecha antigua para cada archivo y carpeta a la ruta de destino coincidentes archivos y carpetas:

(Guardado como ~/bin/copy_dates.rb ; nano ~/bin/copy_dates.rb y pegar)

#!/usr/bin/env ruby

# We require the "find" and "fileutils" libraries to work with files and directories
require 'find'
require 'fileutils'

# Retrieve the source and destination root directories from the command line arguments
src_root = ARGV[0]
dst_root = ARGV[1]

# Count the total number of files in the source root directory
total_files = Dir[File.join(src_root, '**', '*')].count { |file| File.file?(file) }
# Initialize a counter for the current file being processed
current_file = 0

# Traverse through all the files in the source root directory
Find.find(src_root) do |src|
  # Replace the source root path with the destination root path to create the destination file path
  dst = src.sub(/^#{Regexp.escape(src_root)}/, dst_root)

  # Check if the source file exists - for both folders and files:
  if File.exist?(src)
    begin
      # Retrieve the access time (atime) and modification time (mtime) of the source file
      src_atime = File.atime(src)
      src_mtime = File.mtime(src)
      # Use the `stat` command to retrieve the birth or creation time (btime) of the source file
      src_btime = `/usr/bin/stat -f "%SB" -t "%m/%d/%Y %H:%M:%S" "#{src}"`.chomp

      # Retrieve the access time (atime), modification time (mtime), and birth time (btime) of the destination file
      dst_atime = File.atime(dst)
      dst_mtime = File.mtime(dst)
      dst_btime = `/usr/bin/stat -f "%SB" -t "%m/%d/%Y %H:%M:%S" "#{dst}"`.chomp

      # Check if the source and destination file timestamps match
      if src_atime == dst_atime && src_mtime == dst_mtime && src_btime == dst_btime
        puts "[#{current_file}/#{total_files}] #{src}: Skipped - timestamps match"
      else
        # If the timestamps don't match, update the access time and modification time of the destination file
        File.utime(src_atime, src_mtime, dst)
        # Use the `SetFile` command to update the birth time of the destination file
        system("SetFile -d '#{src_btime}' '#{dst}'")
        puts "[#{current_file}/#{total_files}] #{src}: Updated - timestamps copied"
      end

    # If an error occurs while processing a file, catch the exception and print an error message
    rescue Exception => e
      puts "Error processing #{src}: #{e}"
    end
  end

  # Increment the current file counter
  current_file += 1
end

Recuerde hacer el archivo ejecutable y llamarlo como en el siguiente ejemplo:

chmod +x ~/bin/copy_dates.rb
copy_dates.rb /source/path/to/folder /destination/path/to/folder
