python实现的文件夹清理程序分享

使用：
复制代码 代码如下:
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：
复制代码 代码如下:
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):

for f in kf.readlines():
print (f)
if (dir.upper().endswith("\\" + f.strip().upper())):

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：

复制代码 代码如下:
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])
