[Mac] Change Colors of ls Command

I'm currently using iTerm2 and the latest zsh.

In the past, as I remember that if I want to change the color of the ls command, I should set in the LS_COLORS shell variables.

But when I tried to set it with my new Mac in this time, it was LSCOLORS.

Anyway, let's find out this.

Default Value

My Mac's default value was Gxfxcxdxbxegedabagacad.

Oh Jeez, What is this?!!

When I set it up before, it seems that I set it up with an explicit name and number, but now I get an error saying that only certain alphabets and numbers are available when I try it.

warn: LSCOLORS should use characters a-h instead of 0-9 (see the manual page)

Let's dig some more this.

Meaning of the Alphabet

Alphabet	Description	Alphabet	Description
a	black	A	bold black
b	red	B	bold red
c	green	C	bold green
d	brown	D	bold brown
e	blue	E	bold blue
f	magenta	F	bold magenta
g	cyan	G	bold cyan
h	light grey	H	bold light grey
x	default foreground or background

Oh, the alphabet meant color!

※ The brown is sometimes used in yellow, and the light grey is sometimes used in white.
※ The bold is the same meaning of bright.

So, what color is it?

Meaning of the Order

Order	Description
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

Wow, this is what the order meant.

The default value had 22 alphabets.

So, it consisted of the foreground color and background color of each order.

Analyze

Let's match it!!

Values	Description	Foreground Color	Background Color
Gx	directory	bright cyan	default background
fx	symbolic link	magenta	default background
cx	socket	green	default background
dx	pipe	yellow	default background
bx	executable	red	default background
eg	block special	blue	cyan
ed	character special	blue	yellow
ab	executable with setuid bit set	black	red
ag	executable with setgid bit set	black	cyan
ac	directory writable to others, with sticky bit	black	green
ad	directory writable to others, without sticky bit	black	yellow

Now, it's easy to understand, right?

Then change the colors as you want.

 

In the previous, I set the color for specific file extension like "*.sh".

But I don't know how to set it without third party tool now. TwT
