This is the content of file :

Presented like that, it looks like homework... (Do you remember the rules?...)
If I were you I would start by writing on a paper what is to be done:
In other words the algorithm...
Then once satisfied with it translate it to shell script.
Only at this point if it is not satifactory should I ask what we think of the script my posting a thread, explaining us your frustration with your code

And sure you will have replies...

Courage!

Ooppss...Had to edit it...

So here are some tips

Use cat, while, read...

Then you'll probably encounter something weird like not being able to enter your choice of y/n so try searching about tty

Heres some hints:

This
Code:
for line in `cat /path/to/yourfile`; do
    echo $line
    {do something}
done


Then lookup the read command.
