Thanks radoulov. For some reason I had to do small changes for it to work. You probably know the reasonSmilie

Code:
 awk > ouput.txt '/Age:/ && /Email:/' RS='\n\n' input.txt

If I want to put only the entries Email and Age in the output file from the desired record, how do I do that? I know 'print' command can do this, but my syntax always goes wrong.

Thanks again,
Atrisa

Email::Received(3pm)					User Contributed Perl Documentation				      Email::Received(3pm)

NAME
Email::Received - Parse an email Received: header SYNOPSIS
use Email::Received; for ($mail->header("Received")) { my $data = parse_received($_); return "SPAM" if rbl_lookup($data->{ip}); } DESCRIPTION
This module is a Perl Email Project rewrite of SpamAssassin's email header parser. We did this so that the great work they did in analysing pretty much every possible Received header format could be used in applications other than SpamAssassin itself. The module provides one function, "parse_received", which takes a single Received line. It then produces either nothing, if the line is unparsable, a hash reference like this: { reason => "gateway noise" } if the line should be ignored for some good reason, and one like this: { ip => '64.12.136.4', id => '875522', by => 'xxx.com', helo => 'imo-m01.mx.aol.com' } if it parsed the message. Possible keys are: ip rdns helo ident envfrom auth by id RULE FORMAT
Where SpamAssassin used a big static subroutine full of regular expressions to parse the data, we build up a big subroutine full of regular expressions dynamically from a set of rules. The rules are stored at the bottom of this module. The basic format for a rule looks like this: ((var=~)?/REGEXP/)? [ACTION; ]+ The "ACTION" is either "SET variable = $value", "IGNORE "reason"?", "UNPARSABLE" or "DONE". One control structure is provided, which is basically an "if" statement: GIVEN (NOT)? /REGEXP/ { ACTION+ } EXPORT parse_received SEE ALSO
Mail::SpamAssassin::Message::Metadata::Received, from which the rules and some of the IP address matching constants were blatantly stolen. Thanks, guys, for doing such a comprehensive job! AUTHOR
