#定时执行任务命令

#1.定时任务代码

import time,os,sched

# schedule = sched.scheduler(time.time,time.sleep)

# def perform_command(cmd,inc):

#     os.system(cmd)

#     print('task')

# def timming_exe(cmd,inc=60):

#     schedule.enter(inc,0,perform_command,(cmd,inc))

#     schedule.run()

# print('show time after 2 seconds:')

# timming_exe('echo %time%',2)

#2.周期性执行任务

schedule = sched.scheduler(time.time,time.sleep)

def perform_command(cmd,inc):

    #在inc秒后再次运行自己，即周期运行

    schedule.enter(inc, 0, perform_command, (cmd, inc))

    os.system(cmd)

def timming_exe(cmd,inc=60):

    schedule.enter(inc,0,perform_command,(cmd,inc))

    schedule.run()#持续运行，直到计划时间队列变成空为止

print('show time after 2 seconds:')

timming_exe('echo %time%',2)

#3.循环执行命令

# import time,os

# def re_exe(cmd,inc = 60):

#     while True:

#         os.system(cmd)

#         time.sleep(inc)

# re_exe("echo %time%",5)
