#!/usr/bin/perl

#===========whitelist start=======================
$whitelist = $whitelist . "
test\@yahoo.com
test34\@gmail.com
";
#===========whitelist end=======================

#===========blacklist start=====================
$blacklist = $blacklist . "
test\@gmail.com
test987\@yahoo.com
";
#===================blacklist end===============

I have a file containing above. I need to create 2 variables. 1 variable containing the text inside whitelist start and whitelist end and 1 variable containing the text inside blacklist star and blacklist end. What will happen is variable 1 will have test\@yahoo.com and test34\@gmail.com while variable 2 is test\@gmail.com and test987\@yahoo.com

Is there a way I can do this by making a script.

TIA

yes of course. but what have you tried?

I'm not really expert in scripting. What I did is I grep all matching "@" which shows list of email address. I just need to output what's inside whitelist start/end only

its been 4 years since you registered. after that, more than 100++ posts where you learned about sed/awk/Perl/bash etc from people that provide you solutions to your problems. I am sure you have read up a fair amount since then (or have you?). So why don't you try your best. Nobody is an expert on a subject matter without doing something. If you know Perl, use it. Read up docs on how to parse files using Perl.

thanks for the advise. We'll be reading some more perl books

also do this: perldoc perl or perldoc perltoc on your command line.
