python实现的文件夹清理程序分享

使用：

foldercleanup.py -d 10 -k c:\test\keepfile.txt c:\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：

import os

import os.path

import datetime

  

def getOption():

  from optparse import OptionParser

  

  des   = "clean up the folder with some options"

  prog  = "foldercleanup"

  ver   = "%prog 0.0.1"

  usage = "%prog [options] foldername"

  

  p = OptionParser(description=des, prog=prog, version=ver, usage=usage,add_help_option=True)

  p.add_option('-d','--days',action='store',type='string',dest='days',help="keep the subfolders which are created in recent %days% days")

  p.add_option('-k','--keepfile',action='store',type='string',dest='keepfile',help="keep the subfolders which are recorded in text file %keepfile% ")

  options, arguments = p.parse_args()

  

  if len(arguments) != 1:

    print("error: must input one directory as only one parameter ")

    return

  

  return options.days, options.keepfile, arguments[0] 
 

def preCheckDir(dir):

  if(not os.path.exists(dir)):

    print("error: the directory your input is not existed")

    return

  if(not os.path.isdir(dir)):

    print ("error: the parameter your input is not a directory")

    return

    

  return os.path.abspath(dir)

  

def isKeepByDay(dir, day):

  indays = False

  if( day is not None) :

    t = os.path.getctime(dir)

    today = datetime.date.today()

    createdate = datetime.date.fromtimestamp(t)

    indate = today - datetime.timedelta(days = int(day))

    print (createdate)

    if(createdate >= indate):

      indays = True

  print (indays)

  return indays

  

def isKeepByKeepfile(dir, keepfile):

  needkeep = False

  print (dir)

  if (keepfile is not None):

    try :

      kf = open(keepfile,"r")

      for f in kf.readlines():

        print (f)

        if (dir.upper().endswith("\\" + f.strip().upper())):

          needkeep = True

      kf.close()

    except:

      print ("error: keep file cannot be opened")

  print(needkeep)

  return needkeep

    

def removeSubFolders(dir, day, keepfile):

  subdirs = os.listdir(dir)

  for subdir in subdirs:

    subdir = os.path.join(dir,subdir)

    if ( not os.path.isdir(subdir)):

      continue

    print("----------------------")

    if( (not isKeepByDay(subdir, day))and (not isKeepByKeepfile(subdir, keepfile))):

      print("remove subfolder: " + subdir)

      import shutil

      shutil.rmtree(subdir,True)

    

def FolderCleanUp():

  (day, keepfile, dir) = getOption()

  dir = preCheckDir(dir)

  if dir is None:

    return

  removeSubFolders(dir,day,keepfile)

  

if __name__=='__main__':

  FolderCleanUp()

对目录下保留最后的zip文件：

def KeepLastNumZips(num)

    def extractTime(f):

        return os.path.getctime(f)
    zipfiles = [os.path.join(zipdir, f)

                for f in os.listdir(zipdir)

                if os.path.splitext(f)[1] == ".zip"]

    if len(zipfiles) > num:

        zipfiles.sort(key=extractTime, reverse=True)

        for i in range(num, len(zipfiles)):

            os.remove(zipfiles[i])
