用 dircolors -p  可以 看到缺省的颜色设置，包括各种颜色和“粗体”，下划线，闪烁等定义。

而变量 $LS_COLORS  是设置颜色的变量；

如我的设置如下：

export LS_COLORS="no=00:fi=00:di=00;35:ln=00;36:pi=40;33:so=00;35:bd=40;33;01:cd=40;33;01:or=01;05;37;41:mi=01;05;37;41:ex=00;32:*.cmd=00;32:*.exe=00;32:*.com=00;32:*.btm=00;32:*.bat=00;32:*.sh=00;32:*.csh=00;32:*.tar=00;31:*.tgz=00;31:*.arj=00;31:*.taz=00;31:*.lzh=00;31:*.zip=00;31:*.z=00;31:*.Z=00;31:*.gz=00;31:*.bz2=00;31:*.bz=00;31:*.tz=00;31:*.rpm=00;31:*.cpio=00;31:*.jpg=00;35:*.gif=00;35:*.bmp=00;35:*.xbm=00;35:*.xpm=00;35:*.png=00;35:*.tif=00;35:"

另：

/etc/DIR_COLORS 文件为系统默认颜色参数配置文件

如果想修改定义自己的颜色参数配置文件，请执行如下操作：

1. cp /etc/DIR_COLORS $HOME/.dir_colors

2. 修改中的颜色定义 $HOME/.dir_colors

我的配置如下：

# Configuration file for the color ls utility

# This file goes in the /etc directory, and must be world readable.

# You can copy this file to .dir_colors in your $HOME directory to override

# the system defaults.

# COLOR needs one of these arguments: 'tty' colorizes output to ttys, but not

# pipes. 'all' adds color characters to all output. 'none' shuts colorization

# off.

COLOR tty

# Extra command line options for ls go here.

# Basically these ones are:

# -F = show '/' for dirs, '*' for executables, etc.

# -T 0 = don't trust tab spacing when formatting ls output.

OPTIONS -F -T 0

# Below, there should be one TERM entry for each termtype that is colorizable
