python实现的文件夹清理程序分享
使用：
foldercleanup.py-d10-kc:\test\keepfile.txtc:\test
表示对c:\test目录只保留最近10天的子文件夹和keepfile.txt中指定的子文件夹。
代码：
importos
importos.path
importdatetime
defgetOption():
fromoptparseimportOptionParser
des ="cleanupthefolderwithsomeoptions"
prog ="foldercleanup"
ver ="%prog0.0.1"
usage="%prog[options]foldername"

p.add_option('-k','--keepfile',action='store',type='string',dest='keepfile',help="keepthesubfolderswhicharerecordedintextfile%keepfile%")
options,arguments=p.parse_args()
