My first program!

Hi to everyone!
I say from the begining the I'm new to shell scripting but I want to learn it.
My first request sound like this:
I would like to make a shell script the returns a number but in the oposite way
(Ex:
input:123
output:321
)
Can it be done?
And if you would like to explain the commands that are used.
Thanks.

Hi,

you are nearly there. It is as easy as:

Code:
#! /bin/sh
echo "Enter number: "
read number
echo "Number reversed: "
echo $number | rev
