Recursive function in bash

I want to do a function that will return the factorial of a number in bash

Here\'s the current code that doesn\'t work, can anyone tell me what\'s wrong and how to c

Answer 1

Another one implementation using echo instead of return

#!/bin/bash

factorial()
{
        if [ $1 -le 1 ]
        then
                echo 1
        else
                echo $[ $1 * `factorial $[$1-1]` ]
        fi
}
echo "factorial $1 = " `factorial $1`
