Coloring OS X Mavericks Terminal

You'll need to create a “.bash_profile” (sudo nano /) file if there isn't an existing one. Then you'll add the following code:

Line|
[1] |	CLICOLOR=1 #simply enables coloring of your terminal.
[2] |	LSCOLORS=exfxcxdxbxegedabagacad #specifies how to color specific items (this is the default).

Order of the attributes:

“exfxcxdxbx” 1-5
“egedabagacad” 5-11
1. directory. 
2. symbolic link.
3. socket 
4. pipe 
5. executable 
6. block special 
7. character special 
8. executable with setuid bit set 
9. executable with setgid bit set 
10. directory writable to others, with sticky bit 
11. directory writable to others, without sticky bit 

List of colors:

a black 
b red 
c green 
d brown 
e blue 
f magenta 
g cyan 
h light grey 
A bold black, usually shows up as dark grey 
B bold red 
C bold green 
D bold brown, usually shows up as yellow 
E bold blue
