I was trying to write a script that print the arguments in reverse order.
So if I type bash reverse.sh one two three
I expect my output to be three two one

echo i.e. you need to evaluate the expansion, not output it:
eval echo $a$(($#-i))
Note that, using
eval in general is discouraged as this could result in security implications if the input string is not sanitized. Check John1024's answer to see how this can be done without
