PUTTY登陆后，ls如何显示颜色

使用putty登录linux后有时会出现没有颜色，全部为白色，这时要设置相应的颜色配置。  
  
针对不同系统设置不同，  
  
1、对于Ubuntu和Debian系统，修改/etc/bash.bashrc，加入如下：  
  
alias ls='ls --color'  
LS\_COLORS='di=94:fi=0:ln=31:pi=5:so=5:bd=5:cd=5:or=31:mi=0:ex=35:\*.rpm=90'  
export LS\_COLORS  
  
退出，再用putty登录即可显示出颜色。（如果上述设置只在~/.bashrc下，那么每次登录都要source一下，很不方便）  
  
2、对于redhat系列，在/ect/DIR\_color里有相应的颜色设置  
  
附颜色对照表（从别人网页摘来的）：

alias ls='ls --color'  
LS\_COLORS='di=1:fi=0:ln=31:pi=5:so=5:bd=5:cd=5:or=31:mi=0:ex=35:\*.rpm=90'  
export LS\_COLORS

The first line makes ls use the \--color parameter by default, which tells ls to display files in different colours based on the setting of the LS\_COLORS variable.

The second line is the tricky one, and what I have worked out so far has been by trial and error. The parameters (di, fi, etc.) refer to different Linux file types. I have worked them out as shown

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).

The \*.rpm=90 parameter at the end tells ls to display any files ending in .rpm in the specified colour, in this case colour 90 (dark grey). This can be applied to any types of files (eg. you could use '\*.png=35' to make jpeg files appear purple.) As many or as few parameters as you like can go into the LS\_COLORS variable, as long as the parameters are separated by colons.

Using trial and error (and a little bash script I wrote... my first one ever! :) I worked out all the colour codes, at least my interpretation of them -

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

These can even be combined, so that a parameter like:  
di=5;31;42  
in your LS\_COLORS variable would make directories appear in flashing red text with a green background!

Setting LS\_COLORS does more than just make your ls listings look pretty (although it certainly does do that), it is also very helpful in identifying files while wading through a file system.

LS\_COLORS='no=00:fi=00:di=01;33:ln=01;36:pi=40;33:so=01;35:bd=40;33;01:cd=40;33;01:or=01;05;37;41:mi=0  
1;05;37;41:ex=01;32:\*.cmd=01;32:\*.exe=01;32:\*.com=01;32:\*.btm=01;32:\*.bat=01;32:\*.sh=01;32:\*.csh=01;32  
:\*.tar=01;31:\*.tgz=01;31:\*.arj=01;31:\*.taz=01;31:\*.lzh=01;31:\*.zip=01;31:\*.z=01;31:\*.Z=01;31:\*.gz=01;3  
1:\*.bz2=01;31:\*.bz=01;31:\*.tz=01;31:\*.rpm=01;31:\*.cpio=01;31:\*.jpg=01;35:\*.gif=01;35:\*.bmp=01;35:\*.xbm  
=01;35:\*.xpm=01;35:\*.png=01;35:\*.tif=01;35:'  
这个是我的系统里经常用的颜色配置，还不错。
