I learned AWK from different tutorial in my native language Smilie. But you can be safe about the link I gave you. It has everything you need to start learning AWK and it is written in a very simple and explanatory way. After you go through this manual, you should be able to understand the code I gave you for your problem Smilie.

/@/{m=$0;p=0}/: if line contains "@", then assign it into variable "m" (in other words assign email address to variable "m") and clear variable "p".
p++ is incrementing variable "p" if condition is met.

thx man according to your guidance you start your counter with p=0 and when it passes every condition it increases with p++ like p=p+1 and finally if all condition were true your counter has reached 3 according to that we print m and if it wasn't equal to we don't print m .

is that right ?

thx man thx for your great help

another question is if our first line was like "first1@xyz.com Sam,jones"
how can we select only mail address
i think we should pipe our stdout to cut command

and how awk can finds that every Argument like our creation date and POP3 Last Login Date is in a new line or next line and how can our counter back to zero after 4 line

because it wasnt like
for i in `cat file` do ; .....;done

If email address is always in the first field, then just change m=$0 to m=$1. As for the reseting the counter.. It is done when email address is found on the line, so each counter is "private" for particular email address.
