Ruby类正在输出文件和目录

为什么在“print”\n“+f”行下面的类会输出目录和文件名？ 我只想输出文件，但目录也被输出

class Sort



  require 'find'

  directoryToSort = "c:\\test"

   total_size = 0

   Find.find(directoryToSort) do |path|
     if FileTest.directory?(path)
       if File.basename(path)[0] == ?.
         Find.prune       # Don't look any further into this directory.
       else
       Dir.foreach(path) do
       |f|
       # do whatever you want with f, which is a filename within the
       # given directory (not fully-qualified)
         if !FileTest.directory? f
         print "\n"+f
         end
       end
         next
       end
     else
     end
   end

end

考虑改用Ruby标准方法。

它在评论中说：

# do whatever you want with f, which is a filename within the
# given directory (not fully-qualified)

钥匙为“不完全合格”零件。您需要执行以下操作：

if !FileTest.directory? (path + File::SEPARATOR + f)

您需要

File.directory？（filename）

来检查它是否是文件名

你可能想按照这些思路做点什么

这是一个帮助器方法，用于执行递归目录下降和执行块 如果文件名与某个正则表达式匹配，则启用。。对你来说有点过分了，但也许这有帮助
