def traverse_dir(file_path)

    if File.directory? file_path

        Dir.foreach(file_path) do |file|

            if file !="." and file !=".."

                traverse_dir(file_path+"/"+file)

            end

        end

    else

        puts "File:#{File.basename(file_path)}, Size:#{File.size(file_path)}"

    end

end

traverse_dir('D:/apache-tomcat')

二、ruby遍歷文件夾

復(fù)制代碼代碼如下:

def get_file_list(path)  

  Dir.entries(path).each do |sub|         

    if sub != '.' && sub != '..'  

      if File.directory?("#{path}/#{sub}")  

        puts "[#{sub}]"  

        get_file_list("#{path}/#{sub}")  

      else  

        puts "  |--#{sub}"  

      end  

    end  

  end  

end

        fileList.append(dir.decode('gbk'))

    elif os.path.isdir(dir):

            GetFileList(newDir, fileList)  

    return fileList

list = GetFileList('D:\\workspace\\PyDemo\\fas', [])

for e in list:

    print e

result:

復(fù)制代碼代碼如下:

D:\workspace\PyDemo\fas\file1\20141113\a.20141113-1100.log

D:\workspace\PyDemo\fas\file1\20141113\a.20141113-1101.log

D:\workspace\PyDemo\fas\file1\20141113\a.20141113-1140.log

D:\workspace\PyDemo\fas\file2\20141113\a.20141113-1100.log

D:\workspace\PyDemo\fas\file2\20141113\a.20141113-1101.log

D:\workspace\PyDemo\fas\file2\20141113\a.20141113-1140.log

四、簡潔遍歷寫法

復(fù)制代碼代碼如下:

import os

def iterbrowse(path):

    for home, dirs, files in os.walk(path):

        for filename in files:

            yield os.path.join(home, filename)

for fullname in iterbrowse("/home/bruce"):

    print fullname
