	I couldn't disagree more. Color ls is designed specifically to 
replace ls. If you're not going to use it in this manner, I don't think 
you should use it at all. Color ls is the standard ls with patches to 
allow colorized output. If color output is not specified implicitly, 
color ls behaves precicely as does ls, and I have never seen a problem 
with it's interaction with any other utility. The standard method of 
using color is for --color=tty to be used, where color is only outputed 
if the output is going to a true tty, and if the output is instead piped 
to another command, or routed to a file it omits the color codes, preventing 
them from confusing any programs that the output may be sent to.  

	While it is true that ls is a standard system component, it is 
also true that there is more than one version of ls out there, and other 
components in the system rely less on the need to have the 'one true ls' 
than they do on ls following set standards of output. For the purposes of 
interaction with other system components, there is to my knowledge no 
distinction between the behavior of gnu ls and colorized gnu ls.
