HTML Code:
customer names
>cat customer.dat
FirstName1 LastName1
FistName2 LastName1
FistName3 MiddleName3 LastName3
This file can contain areoun 100 customer names.

Quote:
My requirement is to get the customer complete name randomly, I want to use RANDOM to generate random number, and then I want to read the complete name from the customer.dat with line number that matches with the random number

Any idea how to read the file if the line number is specified?
Regards,
