Working at the command line is not as daunting a task as you would think. There is no special knowledge needed to know how to use the command line, it is a program like everything else. Most things in Linux can be done using the command line, although there are graphical tools for most programs, sometimes they are just not enough. This is where the command line comes in handy.

使用命令行并不像您想象的那么困难。使用命令行不需要专门知识，和其它软件一样，它也仅仅是一个程序。Linux 中绝大部分工作都可以用命令行完成，尽管大部分程序都有相应的图形工具，但有时这些图形工具会捉襟见肘，不够用。此时便是命令行大显身手的时候。

The <application>Terminal</application> is located in <menuchoice><guimenu>Applications</guimenu><guimenuitem>Terminal</guimenuitem></menuchoice> . The terminal is often called the command prompt or the shell. In days gone by, this was the way the user interacted with the computer, however Linux users have found that the use of the shell can be quicker than a graphical method and still holds some merit today. Here you will learn how to use the terminal.

<application>终端</application>位于桌面菜单系统中的<menuchoice> <guimenu>应用程序</guimenu><guimenuitem>终端< /guimenuitem> </menuchoice>，它经常被称作命令行方式或shell。终端曾经是用户与计算机交流的唯一方式，现在则出现了图形界面。然而 Linux用户发现，shell使用起来比图形界面更快捷，所以直到今天它仍有其存在的价值。在这里你将学习如何使用终端。

The original use of the terminal was a file browser and indeed it is still used as a file browser, in the event of the graphical environment failing. You can use the terminal as a file browser to navigate your files and undo the changes that have been made.

|
终端最初用作文件浏览器，万一图形环境失效，终端还可以作为文件浏览器使用。您可以将终端作为一个文件浏览器来浏览您的文件和取消曾做过的改动。
