[SOLVED] playing with ls `ls`

[luca]

I were trying to add an alias to my .bashrc file.
My mistakes was to write alias ls=`ls --color` instead of alias ls='ls --color' (I noted the difference between ' and ’ or `) . The result was surprisingly different , with the wrong alias I got the same output as issuing ls `ls --color`

luca@Amilone:~$ ls `ls --color`
ls: impossibile accedere a 2INF.pdf: Nessun file o directory
ls: impossibile accedere a 3INF.pdf: Nessun file o directory
ls: impossibile accedere a Azureus: Nessun file o directory
ls: impossibile accedere a Downloads: Nessun file o directory
ls: impossibile accedere a Desktop: Nessun file o directory
ls: impossibile accedere a Immagini: Nessun file o directory
ls: impossibile accedere a informatica: Nessun file o directory
ls: impossibile accedere a music: Nessun file o directory
ls: impossibile accedere a plasma_output: Nessun file o directory
ls: impossibile accedere a plasma_output~: Nessun file o directory
ls: impossibile accedere a studio: Nessun file o directory
ls: impossibile accedere a surf: Nessun file o directory
ls: impossibile accedere a workspace: Nessun file o directory
ls: impossibile accedere a : Nessun file o directory

Mmmh... Strange no?
The ls man pages tell me nothing about this. Could this be an unwanted behaviour ? Or maybe a cool side effect? Or is this the normal behaviour for bash?

sorry for italian output, read it
ls: can't access at (file contained in home dir): No such file or directory

Hi Luca,
the explanation is easy....
The back tick executes the shell expression, so...

 ls --color gives  (in my home) as output  0001 etc...
(0001 is actually the first file in my home directory), but 
the true output is :
 .[00m.[00m0001.[00m.
as you can see from:
ls --color |head -n 1 |hexdump -C

00000000  1b 5b 30 30 6d 1b 5b 30  30 6d 30 30 30 31 1b 5b  |.[00m.[00m0001.[|
00000010  30 30 6d 0a                                                         |00m.|
00000014

So obviously the execution of ls `ls --color` generates a series of error messages.
Ciao.

Oh, Thanks a lot ! now I understand
so the ls command doesn't print on screen its entire output ? right?
