python 获取linux本机信息【十全十美】

   用python写的获取linux本机信息，包括kernel、IP、Memory、Disk信息。

#Information on this program is used to get the Linux native.                  #
#You can enter the "kernel", "ip", "memory", "disk" keyword to get the results,#
#you can also enter "all".                                                     #

翻译：本程序是用来获取linux本机信息的
      你可以输入“kernel”，“ip”，“memory”，“disk”关键字获取响应的参数信息
      也可以输入“all”，查看所有参数。

程序内容如下：

#!/usr/bin/env python

import os
kernel_version = os.popen('''/bin/uname -a | awk \'{print $1,$3}\'''').read().strip('\n')
ip = os.popen('''/sbin/ifconfig | grep 'inet addr'|awk '{print $2}'|head -1 |cut -d ":" -f 2''').read().strip('\n')
memory = os.popen('''free -m | head -2''').read().strip('\n')
disk = os.popen('''df -hT''').read().strip('\n')

print '''

if   a == 'kernel':
    print "Kernel Version:",kernel_version

        print "Local IP:",ip

        print "Local Memory:" + ('\n') + memory

else:
    print "Didnt't you want to query parameter."

 最近在学习python，所以就各种找需求去练习，写的也简单，各种堆命令，有什么不对的地方或者好的建议，还请指出。
