Shell Programming and Scripting

Not sure about the simplest, but probably the smallest, yes! Here you go:

$cat fib

#!/bin/ksh
if [ $1 -gt 2 ]
then
echo `expr $2 + $3`
fib `expr $1 - 1` $3 `expr $2 + $3`
fi


$fib 10 0 1
1
2
3
5
8
13
21
34



Note above that the script is called with three arguments: no. of terms required, the strating fibionacci term, the next fibionacci term

while [ $i -le $choice ]
do
if [ $i -eq 1 ]
then
echo "$n1\t \c"
elif [ $i -eq 2 ]
then
