        Comecei a estudar o seu script e percebi uma coisa :

NAME
       seq - print a sequence of numbers

SYNOPSIS
       seq [OPTION]... LAST
       seq [OPTION]... FIRST LAST

DESCRIPTION
       Print numbers from FIRST to LAST, in steps of INCREMENT.

       If  FIRST or INCREMENT is omitted, it defaults to 1.  That is, an omit-
       ted INCREMENT defaults to 1 even  when  LAST  is  smaller  than  FIRST.

                for i in $(seq $fim);do
