Python UNIX系统管理指南 / 开普饭

一本个人感觉很不错的书，这些文章算是实践

自带的终端来运行命令

chmod a+x是加读写权限

两个python，前面是目录，后面是选择解释器

#! /usr/bin/env python#A System Information Gathering Scriptimport subprocess

#Command 1uname = "uname"uname_arg = "-a"print ("Gathering system information with %s command:\n" % uname)subprocess.call([uname, uname_arg])

#Command 2diskspace = "df"diskspace_arg = "-h"print ("Gathering diskspace information %s command:\n" % diskspace)subprocess.call([diskspace, diskspace_arg])

#! /usr/bin/env bash#A System Information Gathering Script#Command 1UNAME="uname -a"printf "Gathering system information with the $UNAME command: \n\n"$UNAME

#Command 2DISKSPACE="df -h"printf "Gathering diskspace information with the $DISKSPACE command: \n\n"$DISKSPACE

你看以上的脚本的时候，其实是可以看的出来。输出几乎一样的。

那么call的时候将命令和参数分开写是不必要的。完全可以这样写

subprocess.call("df -h",shell=True")

python

bash

编写你个简单的函数

#! /usr/bin/env bash#A System Information Gathering Script

#Command 1function uname_func ()

{ UNAME="uname -a" printf "Gathering system information with the $UNAME command: \n\n" $UNAME}#Command 2function disk_func (){ DISKSPACE="df -h" printf "Gathering diskspace information with the $DISKSPACE command: \n\n" $DISKSPACE}

function main (){ uname_func disk_func}

Main

#! /usr/bin/env python#A System Information Gathering Scriptimport subprocess

#Command 1def uname_func():

uname = "uname" uname_arg = "-a" print ("Gathering system information with %s command:\n" % uname) subprocess.call([uname, uname_arg])

#Command 2def disk_func():

diskspace = "df" diskspace_arg = "-h" print ("Gathering diskspace information %s command:\n" % diskspace) subprocess.call([diskspace, diskspace_arg])

#Main function that call other functionsdef main(): uname_func() disk_func()

main()
