You cannot. The loop "for" only iterates on lists of values.
(Of course, for a small number of iterations, you can write a script that will generate a list
like "1 2 3 4 5 6 7 8 9 10" for you, but I don't think you are looking for something like this.)

If you are looking for an equivalent of, say,
for (i = 1; i <= 10; i++)
      do_something();

or

for i := 1 to 10 do
      do_something;

or whatever you are more comfortable with,
you can use the following structure:

i=1
while [ $i -le 10 ]
do
      do_something
      i=`expr $i + 1`
done

Manipulating numeric values is no much fun in Bourne shell...
