Python執行shell命令四法

整理：Python執行shell命令四法，示例如下：

#!/usr/bin/env python

# -*- coding: utf-8 -*-

import os

import platform

import subprocess

import commands

def subproc():

print "系統進程數："

subprocess.call("ps -ef|wc -l",shell=True)

def os_popen():

print "IP地址："

os1 = platform.system()

if os1 == "Linux":

print os1

ip1 =os.popen("/sbin/ifconfig eth0|grep 'inet addr'").read().strip().split(":")[1].split()[0]

print "\033[1;32;40m%s\033[0m" % ip1

def os_system():

os_command = 'free -m'

cls_node1 = "命令執行成功...."

cls_node2 = "命令執行失敗...."

if os.system(os_command) == 0:

print "\n\033[1;32;40m%s\033[0m" % cls_node1

else:

print "\n\033[1;31;40m%s\033[0m" % cls_node2

def os_commands():

(status, output) = commands.getstatusoutput('pwd')

print status, output

def main():

subproc()

os_popen()

os_system()

os_commands()

if __name__ == "__main__":

main()
