Here is a easy-to-do-you-set different colours for different kinds of files when using the ls command.

Add the following lines to the bottom of your ~/.bashrc file-

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, the --color parameter by Default,which tells LS-to-display files in different colours Based on thesetting of the ls_colors variable.

The second line was the tricky one, and what I had worked out Sofar had been by trial and error. The parameters (Di, FI, etc.) Refer to different Linux file types. I had worked them out Asshown

di  = directory
fi  = file
ln  = symboliclink
pi  = FIFO file
so  = socketfile
BD  = Block (buffered) special file
cd  = character (unbuffered ) Special file
or  = symbolic linkpointing to a non-existent file (orphan) Br>mi  =non-existent file pointed to by a symbolic link (visible when Youtype ls -l)
ex  = file which isexecutable (ie. have ' x ' set in permissions).

The *.rpm=90 parameter at theend tells LS-to-display any files ending in. rpm in the Specifiedcolour, with this CAs E colour (dark grey). This can is applied toany types of files (eg. you could use ' *.png=35 ' to make JPEG filesappear purple.) As many or as few parameters as you can gointo the ls_colors variable, as long asthe parameters is separate D by colons.

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

0  = default colour
1   = Bold
4   = underlined
5   = Flashing text
7   = Reverse Field
= Red
= Green
= Orange
= Blue
= Purple
= Cyan
PNS = Grey
= Black background41 = Red background
= Green background
= orange background
= blue background
= Purple background
Cyan Background
= Grey background
= dark grey
= Light Red
* * * light green
= YELLOW
94 = light blue
* Purple
= Turquoise
= Dark grey background
101 = Light Red background
102 = Light Green background
103 = Yellow background
104 = light blue background
* = Light purple background
10 6 = Turquoise Background

These can even is combined, so the A parameter like:
Di=5;31;42
In your ls_colors variable would makedirectories appear in flashing red text with a greenbackground!

Setting ls_colors does more than justmake your LS listings look pretty (although it certainly does dothat), it is Also very helpful in identifying files while wadingthrough a file system.
