python實現檔案夾同步

定義SynDirTool類，用於同步兩個檔案夾的內容，從/usr/local/a檔案夾到/usr/local/b檔案夾，執行方法：

Python代碼

python SynDirTool.py /usr/local/a  /usr/local/b

SynDirTool.py檔案內容：

#!/usr/bin/python# -*- coding:utf-8 -*-import osimport shutilimport sysimport loggingclass SynDirTool:def __init__(self,fromdir,todir):self.fromdir = fromdirself.todir = todirdef synDir(self):return self.__copyDir(self.fromdir,self.todir)def __copyDir(self,fromdir,todir):#防止該目錄不存在，建立目錄self.__mkdir(todir)count = 0for filename in os.listdir(fromdir):if filename.startswith('.'):continuefromfile = fromdir + os.sep + filenametofile = todir + os.sep + filenameif os.path.isdir(fromfile):count += self.__copyDir(fromfile,tofile)else:count += self.__copyFile(fromfile,tofile)return countdef __copyFile(self,fromfile,tofile):if not os.path.exists(tofile) :shutil.copy2(fromfile,tofile)logging.info("新增%s ==> %s" % (fromfile,tofile))return 1fromstat = os.stat(fromfile)tostat = os.stat(tofile)if fromstat.st_ctime > tostat.st_ctime:shutil.copy2(fromfile,tofile)logging.info("更新%s ==> %s" % (fromfile,tofile))return 1return 0def __mkdir(self,path):# 去除首位空格path=path.strip()# 去除尾部 \ 符號 或者 /path=path.rstrip(os.sep)# 判斷路徑是否存在isExists=os.path.exists(path)# 判斷結果if not isExists:# 如果不存在則建立目錄logging.info(path+' 目錄建立成功')# 建立目錄操作函數os.makedirs(path)if __name__ == '__main__':srcdir=sys.argv[1]descdir=sys.argv[2]logging.basicConfig(filename='SynDirTool.log', level=logging.INFO)tool = SynDirTool(srcdir,descdir)count += tool.synDir()
