                I want to:
                
                1) make a copy of the file 'cp'
                    now I have disk spaces, and 2 names 
                
                2) rename the file 'mv'
                    I still have only 1 disk space, but
                    it has a new name (or location)
                    
                3) create an alias to the file 'ln'
                     here I have 2 names, 1 disk space
                     
                     ln     <- create a new name, and sets the name count up by 1
                     ln -s  <- (symbolic link) create a new file point to the 
                                orginal file
                                
                                
                     for a "regular link", if I run ls -l
                     I will see "name count" greater than 1 for
                     a file, warn dir ALWAYS have a name count greater than 1
                     because both . and the partent have a name for the dir
                                
                     I can also do ls -il and see the file disk number
                     
                     If I use a symbolic link...
                     then the ls -l will show and arrow pointing to
                     the orginal file, and the first char on the file
                     listing will be an 'l'
