清理日志

Posted 2020-11-16 cathyg

写一个清理日志的程序，把三天前的日志和为空的日志都删掉：

 

 

import os,time,datetime

def timestamps_to_str(timestamp=None,format=‘%Y-%m-%d‘): #时间戳转为格式化时间
    if timestamp:
        time_tuple = time.localtime(timestamp)
        result = time.strftime(format,time_tuple)
    else:
        result = time.strftime(format)
    return result

def str_to_timestamps(string=None,format=‘%Y-%m-%d‘): #格式化时间转为时间戳
    if string:
        time_tuple = time.strptime(string,format)
        result = time.mktime(time_tuple)
    else:
        result = time.time()
    return result

path = r‘C:UsersghtPycharmProjectsuntitledhomeword(day4)logs‘
name = ‘.log‘
def del_log(path):  #把三天前的日志和为空的日志都删掉
    if os.path.exists(path) and os.path.isdir(path):
        today = time.strftime(‘%Y-%m-%d‘)
        cur_timestamp = str_to_timestamps(today)
        date_timestamp = cur_timestamp-86400*3    #3天前时间戳
        date = timestamps_to_str(date_timestamp)  #3天前的日期
        for cur_dir,dirs,files in os.walk(path,name):
            for file in files:
                if name in file:
                    file_time = file.split(‘_‘)[1].split(‘.‘)[0]
                    os.chdir(cur_dir)
                    if file_time<date or os.path.getsize(file) == 0:
                        abs_path = os.path.join(cur_dir, file)
                        os.remove(abs_path)
del_log(path)
