鱼漂 (一直漂)

从windows转移到ubuntu的用户，常常会发现自己在windows在创建/下载/保存的文件经常性出现乱码问题(kubuntu出现问题 的可能性更高一些)。而使用默认播放器打开以往的音乐文件(mp3等)时，出现乱码的机会更是接近100%。出现这个问题是因为文件或是文件标签编码并不 是系统默认的UTF8，而windows系统默认使用的是GBK。只要将文件编码做一下转换就解决乱码的问题。

• 需要用到的工具

 sudo apt-get install convmv iconv python-mutagen

要转换文件编码请先进入要转换文件的目录

• 转换文件名由GBK为UTF8

 convmv -r -f cp936 -t utf8 --notest --nosmart *

• 转换文件内容由GBK到UTF8

 iconv -f gbk -t utf8 $i > newfile 

• 转换 mp3 标签编码

 find . -iname “*.mp3” -execdir mid3iconv -e GBK {} \;

注意：保证自己对需转换文件有写权限

你是否知道，Ubuntu事实上已经为你准备了一套蓝色的主题呢？还包括墙纸、边框和控件！

相信你一定会喜欢的！这个主题就是Blubuntu。

Blubuntu来自Ubuntu官方Wiki上， 目的是提供一个蓝色的又与原本黄色主题风格相似的一套完整的主题。

用它非常简单，因为是Ubuntu官方的，所以只要打一条命令从源里安装即可。

sudo apt-get install blubuntu-look

默认情况下， 它会安装上包括GDM、会话Splash、主题和墙纸在内的所有主题元素，一次性搞定，再也不必自己搭配了吧！

安装好后，可以到“系统”->“首选项”->“外观”来启用它，名字就是Blubuntu。

Upstart is an event-based replacement for the /sbin/init daemon which handles starting of tasks and services during boot, stopping them during shutdown and supervising them while the system is running.

It was originally developed for the Ubuntu distribution, but is intended to be suitable for deployment in all Linux distributions as a replacement for the venerable System-V init.

所以，在ubuntu下面，没有/etc/inittab文件。

概要

A. Most people are aware that you can set the default base profile on a per-workstation basis by replacing the "C:\Documents and Settings\Default User" folder on each local workstation. However, instead of performing this action on every workstation, you can specify a domainwide default profile. To do so, you need to save the required profile to the domain's Netlogon folder as name "Default User," by performing the following steps:

1. Create a profile that you want to use as the basis for all new users and log off as the user.
2. Log on to the workstation as a domain administrator.
3. Start the System Control Panel applet (Start, Settings, Control Panel, System).  Select the Advanced tab. Click Settings in the User Profiles section of the tab. Select the profile you created in the first step and click Copy To.
4. In the "Copy profile to" field, enter a location of \netlogon\default user. In the "Permitted to use" field, click Change and set to Everyone, as the figure shows. Click OK.
5. Click OK to the main User Profiles dialog box, then click OK to the System Properties.

When a new user logs on to a workstation for the first time, he or she will now have a profile based on the default profile stored on the Netlogon share. However, because end users can easily change these default profile settings, you'll typically want to use Group Policy instead of this method to set the mandatory configuration options. Group Policy settings will override attempts by the user to modify the profile settings.

新版本的Cygwin的Clear命令默认没有安装，你需要选择安装ncurses lib后，才可以使用此命令。
