Shell Programming and Scripting

Well of course I was going to code it just like that, but I thought the OP wanted to practice with nested loops.

Thank you all, once again.

oombera, I understand your code the best because it's a little more simple for me to read and understand, but none of the error messages triggered when I tried it out.

Perderabo, Your code worked perfectly for me. I don't understand all the code as much, but it works and thank you for the explanation. I just wanted to try nesting loops and have it fire off different error messages for specific occurances, like not positive, no argument, etc.

I know code should be short and simple, but for me who is just beginning, the long way is more simple.

Thank you again!

Another thing on syntax....

On HP-UX:

((num=num-1))

is about a LOT faster than:

num=`expr $num - 1`

Try them both and use timex to show the difference.
