使用Python2或者Python3定时执行某条命令-马春杰杰

Python2：

import os
import time
def print_ts(message):
    print "[%s] %s"%(time.strftime("%Y-%m-%d %H:%M:%S", time.localtime()), message)
def run(interval, command):
    print_ts("-"*100)
    print_ts("Command %s"%command)
    print_ts("Starting every %s seconds."%interval)
    print_ts("-"*100)
    while True:
        try:
            # sleep for the remaining seconds of interval
            time_remaining = interval-time.time()%interval
            print_ts("Sleeping until %s (%s seconds)..."%((time.ctime(time.time()+time_remaining)), time_remaining))
            time.sleep(time_remaining)
            print_ts("Starting command.")
            # execute the command
            status = os.system(command)
            print_ts("-"*100)
            print_ts("Command status = %s."%status)
        except Exception, e:
            print e
if __name__=="__main__":
    interval = 5
    command = r"ls"
    run(interval, command)

import os

import time

def print_ts(message):

print "[%s] %s"%(time.strftime("%Y-%m-%d %H:%M:%S", time.localtime()), message)

def run(interval, command):

print_ts("-"*100)

print_ts("Command %s"%command)

print_ts("Starting every %s seconds."%interval)

print_ts("-"*100)

while True:

try:

# sleep for the remaining seconds of interval

time_remaining = interval-time.time()%interval

print_ts("Sleeping until %s (%s seconds)..."%((time.ctime(time.time()+time_remaining)), time_remaining))

time.sleep(time_remaining)

print_ts("Starting command.")

# execute the command

status = os.system(command)

print_ts("-"*100)

print_ts("Command status = %s."%status)

except Exception, e:

print e

if __name__=="__main__":

Python3：

    while True:
        try:
            # sleep for the remaining seconds of interval
            time_remaining = interval-time.time()%interval
            print_ts("Sleeping until %s (%s seconds)..."%((time.ctime(time.time()+time_remaining)), time_remaining))
            time.sleep(time_remaining)
            print_ts("Starting command.")
            # execute the command
            status = os.system(command)
            print_ts("-"*100)

        except Exception as e:

    command = r"python3 tmp.py"
    run(interval, command)
