在使用ls 命令时，可以发现不同类型的文件，颜色不同，具体每种颜色代表哪类文件？今天就一起来学习下。

默认情况下，在命令行中输入dircolors 即可了解到具体的配置信息：

[root@localhost ~]# dircolors

LS_COLORS='rs=0:di=01;34:ln=01;36:mh=00:pi=40;33:so=01;35:do=01;35:bd=40;33;01:cd=40;33;01:or=40;31;01:su=37;41:sg=30;43:ca=30;41:tw=30;42:ow=34;42:st=37;44:ex=01;32:*.tar=01;31:*.tgz=01;31:*.arc=01;31:*.arj=01;31:*.taz=01;31:*.lha=01;31:*.lz4=01;31:*.lzh=01;31:*.lzma=01;31:*.tlz=01;31:*.txz=01;31:*.tzo=01;31:*.t7z=01;31:*.zip=01;31:*.z=01;31:*.Z=01;31:*.dz=01;31:*.gz=01;31:*.lrz=01;31:*.lz=01;31:*.lzo=01;31:*.xz=01;31:*.bz2=01;31:*.bz=01;31:*.tbz=01;31:*.tbz2=01;31:*.tz=01;31:*.deb=01;31:*.rpm=01;31:*.jar=01;31:*.war=01;31:*.ear=01;31:*.sar=01;31:*.rar=01;31:*.alz=01;31:*.ace=01;31:*.zoo=01;31:*.cpio=01;31:*.7z=01;31:*.rz=01;31:*.cab=01;31:*.jpg=01;35:*.jpeg=01;35:*.gif=01;35:*.bmp=01;35:*.pbm=01;35:*.pgm=01;35:*.ppm=01;35:*.tga=01;35:*.xbm=01;35:*.xpm=01;35:*.tif=01;35:*.tiff=01;35:*.png=01;35:*.svg=01;35:*.svgz=01;35:*.mng=01;35:*.pcx=01;35:*.mov=01;35:*.mpg=01;35:*.mpeg=01;35:*.m2v=01;35:*.mkv=01;35:*.webm=01;35:*.ogm=01;35:*.mp4=01;35:*.m4v=01;35:*.mp4v=01;35:*.vob=01;35:*.qt=01;35:*.nuv=01;35:*.wmv=01;35:*.asf=01;35:*.rm=01;35:*.rmvb=01;35:*.flc=01;35:*.avi=01;35:*.fli=01;35:*.flv=01;35:*.gl=01;35:*.dl=01;35:*.xcf=01;35:*.xwd=01;35:*.yuv=01;35:*.cgm=01;35:*.emf=01;35:*.axv=01;35:*.anx=01;35:*.ogv=01;35:*.ogx=01;35:*.aac=00;36:*.au=00;36:*.flac=00;36:*.mid=00;36:*.midi=00;36:*.mka=00;36:*.mp3=00;36:*.mpc=00;36:*.ogg=00;36:*.ra=00;36:*.wav=00;36:*.axa=00;36:*.oga=00;36:*.spx=00;36:*.xspf=00;36:';

export LS_COLORS

配置信息中(rs、di、ln等)对应的是不同的不同类型的文件，常见的内容为：

di Directory

fi File

ln Symbolic Link

pi Fifo file

so Socket file

bd Block (buffered) special file

cd Character (unbuffered) special file

or Symbolic Link pointing to a non-existent file (orphan)

mi Non-existent file pointed to by a symbolic link (visible when you type ls -l)

ex File which is executable (ie. has ‘x’ set in permissions).

后面的数字，代表的是呈现样式：

0 = Default Colour

1 = Bold

4 = Underlined

5 = Flashing Text

7 = Reverse Field

31 = Red

32 = Green

33 = Orange

34 = Blue

35 = Purple

36 = Cyan

37 = Grey

40 = Black Background

41 = Red Background

42 = Green Background

43 = Orange Background

44 = Blue Background

45 = Purple Background

46 = Cyan Background

47 = Grey Background

90 = Dark Grey

91 = Light Red

92 = Light Green

93 = Yellow

94 = Light Blue

95 = Light Purple

96 = Turquoise

100 = Dark Grey Background

101 = Light Red Background

102 = Light Green Background

103 = Yellow Background

104 = Light Blue Background

105 = Light Purple Background

106 = Turquoise Background

其中一个类型文件可以设置多种不同的呈现样式，如：di=5;31;42 ，不同呈现样式之间用分号;隔开，不同文件类型之间用冒号:隔开。

另外更加完整的信息可以在/etc/DIR_COLORS 文件中看到：

# Configuration file for the color ls utility

# Synchronized with coreutils 8.5 dircolors

# 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
