I just need to to increment 1 name at a time which if I understand the while statement while line1 is less than 10 it should keep reading and increment by 1.  Is the incrementing a built-in feature of bash while loop.  If I'm right in C or C++ you had to have to use something like "line +1" or " ++line1"
