Why would you post a "problem" which looks like a typical school question which requires an "urgent reply" saying "it must be awk or any other unix command" without any details of the computer technology available to you and what code you have written or tried so far? Urgent why? Because your teacher told you to have the homework done in two days? Urgent because why? Urgent because you took a computer admin job and have no idea how to create a basic
computer program?

Have you ever written a single line of software?

We are not here to beg you to provide basic technology details and we are not here to do you work for you.

So, if you want help, you need to be very technically specific.

Thanks.

I apologize. the "urgent" word came out there by mistake.. i used awk command to create the table and print the values but as you can see that in original output, the fields are arrangee in different orders, hence the columns comes with different values (i.e. columns not matching with its actual fields values). It doesn't need to be awk specially, it can be any command..
