-If you spend much time on the Linux command line (and you probably wouldn't be reading this if you didn't), you've undoubtedly noticed that the ls command displays your files in a number of different colors. You've probably also come to recognize some of the distinctions — directories appearing in one color, executable files in another, etc.
+如果你在 Linux 命令行上花费了大量的时间（如果没有，那么你可能不会读这篇文章），你无疑注意到了 ls 以多种不同的颜色显示文件。你可能也注意到了一些区别 -- 目录是一种颜色，可执行文件是另一种颜色等等。

-The "40" in the definition of pi (shown above) makes the file show up in the terminal (or PuTTY) window with a black background. The 31 makes the font color red. Pipes are special files, and this special handling makes them stand out in a directory listing.
+在 pi 的定义中（如上所示），“40” 是文件显示在带有黑色背景的终端（或 PuTTY）窗口中，31 使字体颜色变红。管道是特殊的文件，这种特殊的处理使它们在目录列表中突出显示。
 
-The **bd** and **cd** definitions are identical to each other — 40;33;01 and have an extra setting. The settings cause block (bd) and character (cd) devices to be displayed with a black background, an orange font, and one other effect — the characters will be in bold.

-The colors and font changes described require that you use an alias for ls that turns on the color feature. This is usually the default on Linux systems and will look like this:
+所描述的颜色和字体变化要求你使用 ls 的别名来打开颜色功能。这通常是 Linux 系统上的默认设置，看起来是这样的：
 ```
 alias ls='ls --color=auto'

-If you wanted to turn off font colors, you could run the **unalias ls** command and your file listings would then show in only the default font color.
+如果要关闭字体颜色，可以运行 **unalias ls** 命令，然后文件列表将仅以默认字体颜色显示。
 
-You can alter your text colors by modifying your $LS_COLORS settings and exporting the modified setting:
+你可以通过修改 $LS_COLORS 设置和导出修改后的设置来更改文本颜色。
 ```
 $ export LS_COLORS='rs=0:di=01;34:ln=01;36:mh=00:pi=40;33:so=01;...

-If you want your modified text colors to be permanent, you would need to add your modified LS_COLORS definition to one of your startup files (e.g., .bashrc).
+如果希望修改后的文本颜色是永久性的，则需要将修改后的 LS_COLORS 定义添加到一个启动文件中，例如 .bashrc。
