Python通过subprocess模块执行系统命令并获取执行结果的方法,让你感觉就像使用系统Shell

subprocess模块是官方推荐使用的一个系统函数调用模块,而getoutput方法则是模仿真实的Shell，下面看一下案例

代码(Windows)

# -*- coding: UTF-8 -*-
import subprocess
cmd = 'ipconfig'
print(subprocess.getoutput(cmd))

执行结果(windows)

代码(Linux)

# -*- coding: UTF-8 -*-
import subprocess
cmd = 'ip a | grep MU'
print(subprocess.getoutput(cmd))

执行结果(linux)

root@l:~# cat sub.py
# -*- coding: UTF-8 -*-
import subprocess
cmd = 'ip a | grep MU'
print(subprocess.getoutput(cmd))
root@l:~# python3 sub.py
