No support for Recusrsive functions in Shell scripting
Hello,
As far as i know, recursive functions are not supported in Shell Scripting.
Anyways, the following script will help you to get the factorial of a number.
#! /bin/sh
echo "Enter a number: "
read num
i=2
res=1
if [ $num -ge 2 ]
then
while [ $i -le $num ]
do
res=`expr $res \* $i`
i=`expr $i + 1`
done
fi
echo "Factorial of $num = $res"
