Public Instance methods

chmod(mode, list, opts = {})

再帰処理機能を付加した File#chmod. オプションの種類が増えている事を除けば FileUtils#chmod_R とほぼ同じ.

    extend LocaleFilter::PrintWrapper

    opts[:recursive] = true
    opts[:warning]   = false

    if path_list.empty?

      return false
    end
    message = %Q(: Change to "#{mode}".)

    path_list.each do |path|
      print path, message, "\n"       if opts[:verbose]
      puts File::Stat.new(path).mode  if opts[:debug]
      next  if opts[:noop]
      File.chmod(mode, path)  rescue warn $!
    end
    return true
  end
chown(owner, group, list, opts = {})

再帰処理機能を付加した File#chown. オプションの種類が増えている事を除けば FileUtils#chown_R とほぼ同じ.
