Answer 1

use following code to align to 20 chars:

printf("%20s", str);

In your case it'll probably be more like

printf("first_name=%15s last_name=%15s Number_id=%10s\n",
        first_name, last_name, Number_id);

Answer 2

Since you don't show your code, it's hard to guess in what form you have your data and how you're handling it. However, jdehaan's answer will work for ksh with slight modification. You will need to modify it further to suit your needs.

printf "first_name=%-15s last_name=%-15s Number_id=%10s\n" $first_name $last_name $Number_id
