I'm semi new to unix/linux and am trying to convert a program I wrote in C++ to a bash script. It's a program that prints Fibonacci's series. I have found scripts that will do it, but I'm trying persistently to get this one to work. The problem occurs when I try to return a value from the function. I get no return or I have done something wrong within the function itself. Any help would be much appreciated. Here's what I have so far:

#!/bin/bash
#Fibonnaci_Series

fibonacci ()
{
n=$1
if [ $n -le 1 ]
then
return $n
else
l=`fibonacci $((n-1))`
r=`fibonacci $((n-2))`
return $((l+r))
fi
}

echo "Enter the limit for Fibonaaci's Series: "
read limit
for((i=0; i<=$((limit-1)); i++))
do
result=$(fibonacci $i)
echo "Fibonacci(" $((i+1)) ") = $result"
done
