[Python]执行Linux命令

使用subprocess模块

import subprocess

# 防火墙服务存在关闭状态
child1 = subprocess.Popen(["systemctl status firewalld | grep Active"], stdout=subprocess.PIPE, shell=True)

print(child1.communicate())

#----执行结果------  (b‘ Active: inactive (dead)\n‘, None)

# samba服务不存在
child2 = subprocess.Popen(["systemctl status smbd | grep Active"], stdout=subprocess.PIPE, shell=True)

print(child2.communicate())

#----执行结果------ Unit smbd.service could not be found. (b‘‘, None)

# network存在激活状态
child3 = subprocess.Popen(["systemctl status network | grep Active"], stdout=subprocess.PIPE, shell=True)

print(child3.communicate())

#----执行结果------
