This ruby script will securely erase files and folders recursively in Linux. You may want to add a action to run this script to the context menu of Nautilus using nautilus-actions . # # Shreds files and folders recursively. Code released under MIT license. NUMBER_OF_PASSES = 20 def shred_files_and_folders(path) if File.directory?(path) files = Dir.entries(path) files.delete_if {|x| x == "." or x == ".." } files.each do |f| if File.directory?(path + '/' + f) shred_files_and_folders(path + '/' + f) else puts ` shred -v -z -u -n#{NUMBER_OF_PASSES} #{path + '/' + f}` end end Dir.rmdir(path) else puts ` shred -v -z -u -n#{NUMBER_OF_PASSES} #{path}` end end ARGV.each do |path| shred_files_and_folders(path) end

The following ruby code will delete from a folder old backups files created with Cobian Backup. The deletion is recursive, so all the folders within the folder will be cleaned. # # Deletes old backups made with Cobian Backup. This code is released under the MIT license. NUMBER_OF_FILES_TO_KEEP = 6 def delete_old_backups(path) files = Dir.entries(path) files.sort! {|x,y| y <=> x } files.delete_if {|x| x == "." or x == ".." } name_of_file = " " new_name_of_file = "" file_cnt = 0 files.each do |f| puts f new_name_of_file = f.split(" ")[0] if new_name_of_file != name_of_file file_cnt = 0 name_of_file = new_name_of_file end if File.directory?(path + '/' + f) delete_old_backups(path + '/' + f) end file_cnt = file_cnt + 1 if file_cnt > NUMBER_OF_FILES_TO_KEEP puts "delete " + path + '/' + f File.delete(path + '/' + f)
