coba bantu pake ruby, taruh aja di cron
#!/usr/bin/env ruby
#file : autodelete.rb
# letak backup direktori
backup_dir = "./"
#pattern file (bukan regex)
file_pattern = "*.txt"
# ambil list dan sort terbalik
files = Dir[backup_dir+file_pattern].sort{|a,b| b.downcase <=> a.downcase }
#hapus kecuali lima file terakhir
files[5..-1].each do |file|
puts "hapus #{file}"
File.delete file
end
