Weird difference in script execution

Hi,

So I have a very simple script which loops over 5 times and prints the iterator value.

Code:
#!/bin/sh
START=1
END=5
for i in $(eval echo "{$START..$END}")
do
        echo "$i"
done

If I save this script in a .sh file and run it in the terminal, the output I get is

Code:
{1..5}

But if I paste the same code in a terminal, I get the following

Code:
1
2
3
4
5

The second one is the expected output, but why is the first case not working as I expect?

I'm totally puzzled. Under cygwin the same code executes okay, but not in a unix shell..Smilie

Thanks.
