You probably can't find the answer because that's a really  
nonsensical thing to do.  Just pipe the output straight to grep in  
the first place; there's no need for cat at all.

ls | grep ...


Of course you might want to step back and think about solving things  
with shell metacharacters first rather than resorting to grep.
