JavaScript是一门客户端的脚本语言，但是你千万不要认为它功能弱哦，因为你看了下面的例子之后就明白了。

　　一. 用JavaScript写的操作系统

　　呵呵,那天同事开玩笑说,要是有个用JS写的操作系统就好了. 我们都笑他异想天开，想不到的是，竟然真的有用JavaScript写的操作系统：JS/UIX。它的网址是：http://www.masswerk.at/jsuix/。

　　* 系统介绍

　　它的首页上是这么说的：JS/UIX 是一个基于Web浏览器的类Unix操作系统，没有使用任何插件技术，完全采用Javascript编写。它包含一个虚拟机、一个shell、虚拟文件系统、进程管理、屏幕终端以及键盘映射。它兼容Netscapge、IE 4以上等浏览器。

　　英文介绍：

JS/UIX is an UN*X-like OS for standard web-browsers, written entirely in JavaScript (no plug-ins used). It comprises a vir-tual machine, shell, virtual file-system, process-management,and brings its own terminal with screen- and keyboard-mapping.

The keyboard accepts the US-ASCII character set.As key-mapping depends from your browser, you may have to use the cursor and backspace buttons at the lower right of the
terminal. A complete keyboard can be accessed at the lower left.

Compatibility: Netscape 4+, MS IE 4+ and DOM-aware browsers.

　　该系统文档也很完善，有一个支持的命令手册：http://www.masswerk.at/jsuix/man.txt，和一个版本历史记录。我测试过它支持Firxfox和IE，看来功能比较强大呀。

　　* 如何使用

　　打开在上面的网址，在页面顶端打开“> open terminal ”链接，那么将出现如下面的一个登陆提示框：

JS/UIX 0.45  starting up [init] ...                                             
                                                                                
  terminal (dhtml-gui) ready.                                                   
  bringing up the file-system ...            ok                                 
  re-entering file-system as root.                                              
  building tree ...                          ok                                 
  trying for RC-file ...                  found                                 
  rc-profile looks good.                                                        
  initializing rc-profile ...                ok                                 
  re-entering tree for command-system ...    ok                                 
  setting up system variables ...            ok                                 
  system up and stable.                                                         
  starting login-demon.                                                         
                                                                                
                                                                                
  JS/UIX:Log-on - type user-name (e.g. "guest") and hit <return>.               
                                                                                
 login:                                                                         
                                                                                
                                                                                
　　在login中输入guest，回车就可以登陆了。进去以后就能够看到下面的提示：

                                Terminal ready.                                 
 JS/UIX 0.45 - The JavaScript virtual OS and terminal application for the web.  
 Type "info" for site information. Type "help" for available commands.
