loop for i in $* that is equivalent to for i :

What is exactly mean "$* " ?
As far as I know just "*" means all files current directory

'man ksh'

       Modifiers can be applied to the ${name} form of parameter substitution:

       *      All positional parameters (except  parameter  0),  i.e.,  $1  $2
              $3....   If  used outside of double quotes, parameters are sepa-
              rate words (which are subjected  to  word  splitting);  if  used
              within  double  quotes,  parameters  are  separated by the first
              character of the IFS parameter (or the empty string  if  IFS  is
              null).
