python脚本执行shell，通过crontab执行python脚本#!/usr/bin/env python #-*-coding:utf-8-*- import os import time import datetime import subprocess today =datetime.date.today() deltadays = datetime.timedelta(days=1) #确定日期差额，如前天 days=2 yesterday = today - deltadays month = yesterday.strftime('%b') date = yesterday.strftime('%d') command1 = "ls -hl /log1 | grep '%s %s' | awk '{print i$9}' i='/log1/' | xargs rm " % (month, date) command11 = "ls -hl /log1 | grep '%s %s' | awk '{print i$9}' i='/log1/' | xargs rm " % (month, date) command2 = "ls -hl /log2 | grep '%s %s' | awk '{print i$9}' i='/log2/' | xargs rm " % (month, date) command22 = "ls -hl /log2 | grep '%s %s' | awk '{print i$9}' i='/log2/' | xargs rm " % (month, date) os.system(command1) os.system(command11) os.system(command2) os.system(command22)注意ls -hl /log2 | grep '%s %s' | awk '{print i$9}' i='/log2/' | xargs rm这段shell命令最好是通过python执行shell答应看下具体的文件列出来的格式，防止无效print os.system("ls -hl /log2")这样运行后就能得出结果。然后根据具体情况修改就好了。
