Calife A lightweight alternative to sudo
================================================================================
Calife requests user's own password for becoming login (or root, if no login is provided), and switches to that user and group ID after verifying proper rights to do so. A shell is then executed. If calife is executed by root, no password is requested and a shell with the appropriate user ID is executed.
The invoked shell is the user's own except when a shell is specified in the configuration file calife.auth.
If "-" is specified on the command line, user's profile files are read as if it was a login shell.
This is not the traditional behavior of su.
Only users specified in calife.auth can use calife to become another one with this method.
calife.auth is installed as /etc/calife.auth
### Calife Features ###
Here is an extensive list of features:
you keep your environment variables and shell aliases intact
it has start and end of session logging
you can have a list of all permitted logins for each calife user. That way, you can give a user newsmasters rights without giving out the root password
you can specify a group in the configuration file instead of the logins of all administrators: Juste use @staff or %staff and all members of the staff group will have access to calife
calife can also be used to become users even if they have no home directory or even no shell. Thats very practical if you want to become uucp or even bin
you can make calife runs a specific system-wide script at the end of the session (to send a mailabout what was done as root for example)
### Install calife in ubuntu ###
Open the terminal and run the following command
sudo apt-get install calife
### Using Calife ###
### Syntax ###
calife [-] [login]
Check calife manpage for more details

2 Ways To Fix The UEFI Bootloader When Dual Booting Windows And Ubuntu
================================================================================
The main problem that users experience after following my [tutorials for dual booting Ubuntu and Windows 8][1] is that their computer continues to boot directly into Windows 8 with no option for running Ubuntu.
Here are two ways to fix the EFI boot loader to get the Ubuntu portion to boot correctly.
![Set GRUB2 As The Bootloader.](http://0.tqn.com/y/linux/1/L/E/J/1/grub2.JPG)
### 1. Make GRUB The Active Bootloader ###
There are a few things that may have gone wrong during the installation.
In theory if you have managed to install Ubuntu in the first place then you will have [turned off fast boot][2].
Hopefully you [followed this guide to create a bootable UEFI Ubuntu USB drive][3] as this installs the correct UEFI boot loader.
If you have done both of these things as part of the installation, the bit that may have gone wrong is the part where you set GRUB2 as the boot manager.
To set GRUB2 as the default bootloader follow these steps:
1.Login to Windows 8
2.Go to the desktop
3.Right click on the start button and choose administrator command prompt
4.Type mountvol g: /s (This maps your EFI folder structure to the G drive).
5.Type cd g:\EFI
6.When you do a directory listing you will see a folder for Ubuntu. Type dir.
7.There should be options for grubx64.efi and shimx64.efi
8.Run the following command to set grubx64.efi as the bootloader:
bcdedit /set {bootmgr} path \EFI\ubuntu\grubx64.efi
9:Reboot your computer
10:You should now have a GRUB menu appear with options for Ubuntu and Windows.
11:If your computer still boots straight to Windows repeat steps 1 through 7 again but this time type:
bcdedit /set {bootmgr} path \EFI\ubuntu\shimx64.efi
12:Reboot your computer
What you are doing here is logging into the Windows administration command prompt, mapping a drive to the EFI partition so that you can see where the Ubuntu bootloaders are installed and then either choosing grubx64.efi or shimx64.efi as the bootloader.
So [what is the difference between grubx64.efi and shimx64.efi][4]? You should choose grubx64.efi if secureboot is turned off. If secureboot is turned on you should choose shimx64.efi.
In my steps above I have suggested trying one and then trying another. The other option is to install one and then turn secure boot on or off within the UEFI firmware for your computer depending on the bootloader you chose.
### 2. Use rEFInd To Dual Boot Windows 8 And Ubuntu ###
The [rEFInd boot loader][5] works by listing all of your operating systems as icons. You will therefore be able to boot Windows, Ubuntu and operating systems from USB drives simply by clicking the appropriate icon.
To download rEFInd for Windows 8 [click here][6].
After you have downloaded the file extract the zip file.
Now follow these steps to install rEFInd.
1.Go to the desktop
2.Right click on the start button and choose administrator command prompt
3.Type mountvol g: /s (This maps your EFI folder structure to the G drive)
4.Navigate to the extracted rEFInd folder. For example:
cd c:\users\gary\downloads\refind-bin-0.8.4\refind-bin-0.8.4
When you type dir you should see a folder for refind
5.Type the following to copy refind to the EFI partition:
xcopy /E refind g:\EFI\refind\
6.Type the following to navigate to the refind folder
cd g:\EFI\refind
7.Rename the sample configuration file:
rename refind.conf-sample refind.conf
8.Run the following command to set rEFInd as the bootloader
bcdedit /set {bootmgr} path \EFI\refind\refind_x64.efi
9.Reboot your computer
10.You should now have a menu similar to the image above with options to boot Windows and Ubuntu
This process is fairly similar to choosing the GRUB bootloader.
Basically it involves downloading rEFInd, extracting the files. copying the files to the EFI partition, renaming the configuration file and then setting rEFInd as the boot loader.
### Summary ###
Hopefully this guide has solved the issues that some of you have been having with dual booting Ubuntu and Windows 8.1. If you are still having issues feel free to get back in touch using the email link above.

Linux FAQs with Answers--How to install Kingsoft Office on Linux
================================================================================
> **Question**: I heard good things about Kingsoft Office, so I would like to try it out on my Linux. How can I install Kingsoft Office on [insert your Linux distro]?
Kingsoft Office is an office suite available for muliple platforms including Windows, Linux, iOS and Android. It comes with three programs: Writer for word processing, Presentation for presentations, and Spreadsheets for spreadsheets. It is freemium model, where the basic version is free to use. Compared to other Linux office suites such as LibreOffice or OpenOffice, the best advantage of Kingsoft Office is its **excellent compatibility with Microsoft Office**. Thus for those of you who need to use an office suite on Linux and Windows platforms interchangeably, Kingsoft Office is a good choice for Linux platform.
### Install Kingsoft Office on CentOS, Fedora or RHEL ###
Download a RPM file for the [official site][1]. The official RPM package is available as a 32-bit version only, but you can install it on both 32-bit and 64-bit systems.
Use yum command with "localinstall" option to install the RPM file.
$ sudo yum localinstall kingsoft-office-9.1.0.4244-0.1.a12p3.i686.rpm
Note that do NOT use rpm command to install it. Otherwise, you will get unmet dependency errors, which are not easy to solve manually:
error: Failed dependencies:
libICE.so.6 is needed by kingsoft-office-9.1.0.4244-0.1.a12p3.i686
libSM.so.6 is needed by kingsoft-office-9.1.0.4244-0.1.a12p3.i686
libX11.so.6 is needed by kingsoft-office-9.1.0.4244-0.1.a12p3.i686
libXext.so.6 is needed by kingsoft-office-9.1.0.4244-0.1.a12p3.i686
libXrender.so.1 is needed by kingsoft-office-9.1.0.4244-0.1.a12p3.i686
libc.so.6 is needed by kingsoft-office-9.1.0.4244-0.1.a12p3.i686
Red Hat based distributions have multilib support. If the RPM package you are trying to install is 32-bit and has 32-bit library dependencies, a better way is to use yum to install it as shown above. As long as the RPM is properily built with all dependency information, yum should be able to install it using yum repositories.
![](https://farm9.staticflickr.com/8626/16040291445_ca62275064_c.jpg)
### Install Kingsoft Office on Debian, Ubuntu or Linux Mint ###
Download a DEB package from the [official site][2]. The official DEB package is available as a 32-bit version only, but you can install it on both 32-bit and 64-bit systems.
The DEB package has a set of dependencies to meet. Therefore use [gdebi][3] instead of dpkg command to automatically resolve dependencies.
$ sudo apt-get install gdebi-core
$ sudo gdebi kingsoft-office_9.1.0.4244~a12p3_i386.deb
### Launch Kingsoft Office ###
Once Kingsoft Office is installed, you can launch Witer, Presentation, and Spreadsheets from the desktop manager easily.
On Ubuntu Unity:
![](https://farm9.staticflickr.com/8591/16039583702_632a49779f_z.jpg)
On GNOME:
![](https://farm9.staticflickr.com/8617/16039583622_4e7c1d8545_b.jpg)
Alternatively, you can also launch Kingsoft Office from the command line.
To launch Kingsoft Writer from the command line, use this command:
![](https://farm8.staticflickr.com/7525/16039583642_7202457899_c.jpg)
To launch Kingsoft Presentation from the command line, use this command:

Calife —— 一个轻量级的sudo替代方案
================================================================================
Calife要求用户用户以自己的密码登录或者root如果没有提供登录在验证具有正确的权限后就会切换到该用户以及组身份然后就会执行一个shell。如果calife是由root执行的不需要密码一个具有恰当用户ID的shell就会被执行。
唤醒的shell是用户自身的除非在calife.auth配置文件中指定了某个shell。
如果在命令行指定了“-”选项就会读取该用户的环境文件该shell就像是一个登陆shell。
这不是su的惯用操作。
只有在calife.auth中指定的用户才能使用此方法通过calife成为另外一个用户。
calife.auth安装位置处于/etc/calife.auth。
### Calife特性 ###
这里给出了一个关于calife特性的扩展列表
你可以完整保留环境变量和shell别名
它可以全程记录会话开始到结束
你可以为每个calife用户许可的登录制作列表那样你就可以用户赋予主管权限而不必提供root密码
你可以在配置文件中指定一个组来取代所有管理员登录:只要使用@staff或者%staff那么所有staff组中的成员都将具有访问calife的权限
calife也可以成为那些没有家目录或甚至没有shell的用户。如果你想要成为uucp或者甚至是bin那会很实用
你可以让calife在会话结束时运行一个指定的系统范围的脚本例如发送一封邮件告知以root身份做了哪些事
### ubuntu中安装calife ###
打开终端,然后运行以下命令
sudo apt-get install calife
### 使用Calife ###
### 语法 ###
calife [-] [login]
详情请参与calife手册页

Windows和Ubuntu双系统修复UEFI引导的两种办法
=======================================================================
读者在读过我的[安装Ubuntu和Windows 8双系统教程][1]以后碰到的主要的问题是电脑直接启动到Windows 8而没有出现启动Ubuntu的选项。
这里有两种修复EFI启动引导的方法使Ubuntu可以正常启动
![](http://0.tqn.com/y/linux/1/L/E/J/1/grub2.JPG) "将GRUB2设置为启动引导"
### 1. 启用GRUB引导 ###
在安装时,有些地方可能会出问题。
理论上来说如果你首先安装Ubuntu那么你需要[关闭快速启动][2]。
希望你[按照这个指南创建一个UEFI Ubuntu 启动优盘][3]安装正确的UEFI引导程序。
如果你在安装时已经完成了这些事情那么可能出错的地方就是将GRUB2设置为启动管理器。
可以按照以下几个步骤将GRUB2设置为默认的引导程序
1.登录Windows 8
2.转到桌面
3.右击开始按钮,选择管理员命令行
4.输入 mountvol g: (将你的EFI目录结构映射到G盘)
5.输入 cd g:\EFI
6.当你输入 dir 列出文件夹内容时你可以看到一个Ubuntu的文件夹
7.这里的参数可以是grubx64.efi或者shimx64.efi
8.运行下列命令将grub64.efi设置为启动引导程序
bcdedit /set {bootmgr} path \EFI\ubuntu\grubx64.efi
9.重启你的电脑
10.你将会看到一个包含Ubuntu和Windows选项的GRUB菜单
11.如果你的电脑仍然直接启动到Windows重复步骤1到7但是这次输入
bcdedit /set {bootmgr} path \EFI\ubuntu\shimx64.efi
12.重启你的电脑
这里你做的事情是登录Windows管理员命令行将EFI引导区映射到磁盘上来查看Ubuntu的引导程序是否安装成功然后选择grubx64.efi或者shimx64.efi作为引导程序。
那么[grubx64.efi和shimx64.efi有什么区别呢][4]在安全启动serureboot关闭的情况下你可以使用grubx64.efi。如果安全启动打开则需要选择shimx64.efi。
在我上面的步骤里面我建议先试一个然后再试试另外一个。另外一种方法是选择一个然后根据你选择的引导程序在BIOS中启用或者禁用安全启动。
### 2.使用rEFInd引导Ubuntu和Windows双系统 ###
[rEFInd引导程序][5]会以图标的方式列出你所有的操作系统。因此你可以通过点击相应的图标来启动Windows、Ubuntu或者优盘中的操作系统。
[点击这里][6]下载rEFInd for Windows 8。
下载和解压以后按照以下的步骤安装rEFInd。
1.返回桌面
2.右击开始按钮,选择管理员命令行
3.输入 mountvol g: (将你的EFI目录结构映射到G盘)
4.进入解压的rEFInd目录。例如
cd c:\users\gary\downloads\refind-bin-0.8.4\refind-bin-0.8.4
当你输入 dir 命令你可以看到一个refind目录
5.输入如下命令将refind拷贝到EFI引导区
xcopy /E refind g:\EFI\refind\
6.输入如下命令进入refind文件夹
cd g:\EFI\refind
7.重命名示例配置文件
rename refind.conf-sample refind.conf
8.运行如下命令将rEFind设置为引导程序
bcdedit /set {bootmgr} path \EFI\refind\refind_x64.efi
9.重启你的电脑
10.你将会看到一个包含Ubuntu和Windows的图形菜单
这个过程和选择GRUB引导程序十分相似。
简单的说主要是下载rEFind解压文件。拷贝文件到EFI引导区重命名配置文件然后将rEFind设置为引导程序。
### 概要 ###
希望这篇文章可以解决有些人在安装Ubuntu和Windows 8.1双系统时出现的问题。如果你仍然有问题,可以通过上面的电邮和我进行交流。

Linux有问必答 - linux如何安装WPS
================================================================================
> **问题**: 我听说一个好东西Kingsoft Office译注就是WPS所以我想在我的Linux上试试。我怎样才能安装Kingsoft Office呢
Kingsoft Office 一套办公套件支持多个平台包括Windows, Linux, iOS 和 Android。它包含三个组件WriterWPS文字用来文字处理PresentationWPS演示支持幻灯片SpereadsheetsWPS表格为电子表格。使用免费增值模式其中基础版本是免费使用。比较其他的linux办公套件如LibreOffice、 OpenOffice最大优势在于Kingsoft Office能最好的兼容微软的Office译注版权问题了解下wps和Office的历史问题可以得到一些结论。因此如果你需要在windowns和linux平台间交互Kingsoft office是一个很好的选择。
### CentOS, Fedora 或 RHEL中安装Kingsoft Office ###
在[官方页面][1]下载RPM文件.官方RPM包只支持32位版本linux但是你可以在64位中安装。
需要使用yum命令并用"localinstall"选项来本地安装这个RPM包
$ sudo yum localinstall kingsoft-office-9.1.0.4244-0.1.a12p3.i686.rpm
注意不要使用rpm命令安装。否者你会得到依赖错误而且很难解决
错误: 依赖失败:
libICE.so.6 is needed by kingsoft-office-9.1.0.4244-0.1.a12p3.i686
libSM.so.6 is needed by kingsoft-office-9.1.0.4244-0.1.a12p3.i686
libX11.so.6 is needed by kingsoft-office-9.1.0.4244-0.1.a12p3.i686
libXext.so.6 is needed by kingsoft-office-9.1.0.4244-0.1.a12p3.i686
libXrender.so.1 is needed by kingsoft-office-9.1.0.4244-0.1.a12p3.i686
libc.so.6 is needed by kingsoft-office-9.1.0.4244-0.1.a12p3.i686
基于Red Hat的发行版有多重库支持。如果你要想安装的RPM包是32位的并有32位库依赖你的系统是64位的一个很好的解决方法就是使用yum来安装。只要RPM在构建时候已经添加所有依赖关系yum就可以自动使用yum库解决依赖关系。
![](https://farm9.staticflickr.com/8626/16040291445_ca62275064_c.jpg)
### Debian, Ubuntu 和 Linux Mint 中安装Kingsoft Office###
在[官方页面][1]下载DEB包。官方RPM包同样只支持32位版本linux但是你可以在64位中安装。
DEB包同样遇到一堆依赖。因此使用[gdebi][3]命令来代替dpkg来自动解决依赖。
$ sudo apt-get install gdebi-core
$ sudo gdebi kingsoft-office_9.1.0.4244~a12p3_i386.deb
### 启动 Kingsoft Office ###
安装完成后你就可以在桌面管理器轻松启动WiterWPS文字, PresentationWPS演示, and SpreadsheetsWPS表格如下图
Ubuntu Unity中:
![](https://farm9.staticflickr.com/8591/16039583702_632a49779f_z.jpg)
GNOME桌面中:
![](https://farm9.staticflickr.com/8617/16039583622_4e7c1d8545_b.jpg)
不但如此你也可以在命令行中启动Kingsoft Office
启动WirterWPS文字使用这个命令
$ wps (译注:原文丢失此命令)
![](https://farm8.staticflickr.com/7525/16039583642_7202457899_c.jpg)
启动PresentationWPS演示使用这个命令
$ wpp
![](https://farm8.staticflickr.com/7570/15420632223_4243cc99d9_c.jpg)
启动SpreadsheetsWPS表格使用这个命令
$ et
