Thank you for replying! I assume that I would be needing to use this part in the link you sent me: 
   open(PASSWD, '/etc/passwd');
   while (<PASSWD>) {
   chomp;
   ($login, $passwd, $uid, $gid,$gcos, $home, $shell) = split(/:/);
    #...
   }

What exactly is the first line doing? The while is reading through the file at the directory /etc/passwd ?

For my purposes would I write

open READINGFILE, "data.txt" or die $!;
open LOGFILE, ">>logfile.txt" or die $!;


 while (<READINGFILE>) {
     
     chomp;
     ($domain, $IP) = split(/,/);
    if ($ip_obj->{src_ip} eq $IP){
        print LOGFILE $domain;
        print LOGFILE " has been found";
    
    }
}

Right now I'm getting errors:

Global symbol "$domain" requires explicit package name at test.pl line
+ 113.
Global symbol "$IP" requires explicit package name at test.pl line 113

Global symbol "$IP" requires explicit package name at test.pl line 114

    (F) You've said "use strict" or "use strict vars", which indicates
    that all variables must either be lexically scoped (using "my" or 
+"state"),

    declared beforehand using "our", or explicitly qualified to say
    which package the global variable is in (using "::").

Uncaught exception from user code:

What am I missing?

And yes I have several files at various steps in the process to make sure I don't take steps backwards, thanks for the advice though and the link is a good reference but I need it a little more... dumbed down for me to understand. lol.
