how to list file and sort by filename using ls

[Zhao Peng]

Now I should say good afternoon :)

Using either "ls -ul" or "ls -cl"(which are supposed to sort by name 
according to manual, if I understood and used correctly), I just can't 
list files and sort them by filenames.

Google results of key word ""sort by name" linux ls" is pretty much the 
same as man ls, not helpful.

OS: Redhat Enterprise.

Any clue? Thanks,

Zhao

P.S.sorry if this sounds UNbelievably naive/stupid. :)
