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()
