Shell script pipe input - bash mostly

Hi
I've been working on trying to create shell script that can accept piped data from another command.
example would be
ls -al | ./myscript.sh

#!/bin/bash
title=$1
data=$2
echo "title = $title"
echo "data = $data"
echo -e -n "\033[7s"
tput cup 0 0
echo -n $title
echo -e -n "\033[8u"
echo -n $data

So, what it suppose to do is to print the title at location 0 0 of the screen and then list the file at the current location of the cursor. The output should look somehow like below:

[ My Program ]**********************************************

drwxr-xr-x 4 nobody nobody 376 Sep 11 09:59 .

I don't know what you call $title and $data but try this :

Code:

#!/bin/bash

while read data; do
    echo "data = $data"
done

ls -al | ./myscript.sh

Is this what you mean?

Code:

#!/bin/bash
tput cup 0 0
echo "[ my program ] *************"
cat -
