移除七天前檔案

無心幹正事，可是卻有心搞 script，這真是…

#!/usr/bin/env python
# Usage:
#   remove_files_older_than.py ./*.jpg
import sys
import glob
import stat
import os
import time
if len(sys.argv)expireDays :
print diff/(60.0*60*24)
print "Remove %s, mtime=%s..." % (filename, time.strftime(
"%Y/%m/%d %H:%M:%S", modifiedTime ) )
os.remove( filename )
deletedCount=deletedCount+1
if deletedCount > 0:
print "Remove %d files" % deletedCount
else:
print "No files expired."
