[debian]Debain系统使用技巧

摘要：添加无线网卡驱动设置本地文件，为软件仓库源添加在线仓库源添加超级用户权限这个是不需要输入密码的添加中文支持选择等几个和中文相关的添加输入法按如下方式添加，特别注意使用命令

#check out your wireless card
lspci

#Download the firmware of the wifi card
from the website below,u will get want u want
https://wiki.debian.org/brcm80211

#downlaod the iso files below (from site: mirrors.hust.edu.cn):
debian-8.2.0-amd64-DVD-1.iso                       
debian-8.2.0-amd64-DVD-2.iso                     
debian-8.2.0-amd64-DVD-3.iso    
#make three folders
mk /mnt/dvd1
mk /mnt/dvd2
mk /mnt/dvd3
#mount your iso files like this 
mount -o loop debian-8.2.0-amd64-DVD-1.iso  /mnt/dvd1
mount -o loop debian-8.2.0-amd64-DVD-2.iso  /mnt/dvd2
mount -o loop debian-8.2.0-amd64-DVD-3.iso   /mnt/dvd3

#modify your source.list file like this
vi /etc/apt/source.list

deb file:///mnt/dvd1/ jessie contrib main
deb file:///mnt/dvd2/ jessie contrib main
deb file:///mnt/dvd3/ jessie contrib main

#good job! do update and install work
apt-get update
apt-get install xxx

deb http://mirrors.aliyun.com/debian/ jessie contrib main

su root
apt-get install sudo 

vim /etc/sudoers

yyp  and add your user name

gaoy  ALL=NOPASSWD: ALL     <-- 这个是不需要输入密码的  

sudo dpkg-reconfigure locales

下载

安装：
sudo dpkg -i xx.deb
激活：
xxx
设置dash搜索图标
sudo cp /usr/lib/wingide5/resources/linux/desktop/wingide5.desktop   /usr/share/applications/

#运行
gnome-tweak-tool
#常用工具包含
1：添加开机启动程序
2：设置系统主题
3：设置桌面显示图标（桌面可存放文件（夹））
4：设置背景图片和锁屏时的图片 
5：设置系统字体
等等

系统默认使用python 2.7.9
#安装ipython
sudo apt-get install ipython
#安装pip
sudo apt-get install python-pip
#安装pyqt4
sudo apt-get install pyqt4-dev-tools

#下面的包会被安装
  libmysqlclient18 libqt4-declarative libqt4-designer libqt4-help libqt4-network libqt4-opengl libqt4-script libqt4-scripttools libqt4-sql
  libqt4-sql-mysql libqt4-svg libqt4-test libqt4-xmlpatterns libqtassistantclient4 libqtwebkit4 mysql-common python-qt4 python-sip
Suggested packages:
  libqt4-declarative-folderlistmodel libqt4-declarative-gestures libqt4-declarative-particles libqt4-declarative-shaders qt4-qmlviewer
  libqt4-dev python-qt4-dbg
The following NEW packages will be installed:
  libmysqlclient18 libqt4-declarative libqt4-designer libqt4-help libqt4-network libqt4-opengl libqt4-script libqt4-scripttools libqt4-sql
  libqt4-sql-mysql libqt4-svg libqt4-test libqt4-xmlpatterns libqtassistantclient4 libqtwebkit4 mysql-common pyqt4-dev-tools python-qt4
  python-sip

#在ipython中测试一下，是否安装成功了
In [1]: import PyQt4
In [2]: import PyQt4.QtCore
In [3]: from  PyQt4.QtCore import *



#pyqt使用例子
from PyQt4.QtCore import *
a=QString("apple")
print type(a)  #PyQt4.QtCore.QString 

#使用apt-get安装的版本太旧，功能已经无法满足需要，很多文件无法正常解压
#下载下面文件 
wget http://www.rarlab.com/rar/rarlinux-x64-5.3.b4.tar.gz
#解压后，进入目录，复制已经编译好的unrar rar程序到/usr/bin目录
cp rar unrar /usr/bin

#解压命令
unrar e xxx.rar

这条shell语句在调试程序时，是非常有用的
 while true; do xdotool getmouselocation; sleep 0.1; clear; done


#需要安装 xdotool工具
sudo apt-get install xdotool

PyQt写的一个小工具，还可以https://github.com/frans-fuerst/screensnippet

#用起来还是不方便，回头用Qt写个图形用户界面的程序
countdown()
(
  IFS=:
  set -- $*
  secs=$(( ${1#0} * 3600 + ${2#0} * 60 + ${3#0} ))
  while [ $secs -gt 0 ]
  do
    sleep 1 &
    printf "

    secs=$(( $secs - 1 ))
    wait
  done
  echo
)
