python移除系统多余大文件-乾颐堂

文件多了乱放， 突然有一天发现硬盘空间不够了， 于是写了个python脚本搜索所有大于10MB的文件，看看这些大文件有没有重复的副本，如果有，全部列出，以便手工删除

使用方式 加一个指定目录的参数

比如python redundant_remover.py /tmp

主要用到了stat模块，os、sys系统模块

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33

import os, sys #引入统计模块 from stat import * BIG_FILE_THRESHOLD = 10000000L dict1 = {}    # filesize 做 key, filename 做 value dict2 = {}     # filename 做 key, filesize 做 value def treewalk(path):     try:         for i in os.listdir(path):             mode = os.stat(path+"/"+i).st_mode             if S_ISDIR(mode) <> True:                 filename = path+"/"+i                 filesize = os.stat(filename).st_size                 if filesize > BIG_FILE_THRESHOLD:                     if filesize in dict1:                                                dict2[filename] = filesize                         dict2[dict1[filesize]]=filesize                     else:                         dict1[filesize] = filename                               else:                 treewalk(path+"/"+i)     except WindowsError:         pass def printdict(finaldict):     for i_size in finaldict.values():         print i_size         for j_name in finaldict.keys():             if finaldict[j_name] == i_size:                 print j_name         print " " if __name__=="__main__":     treewalk(sys.argv[1])     printdict(dict2)
