Hi 2 all. Is there a possibility to write some reltime log parser? I mean in case of using File::Tail, can I detect some string (by regular expression) in a continuously written file, and then pass that string as an argument for some subroutine or external script ? I've took an example from CPAN but I'm not fully understand how it works, here's the code: 
my $name = "/var/log/squid/access.log";
my $res = ban ($_);
my $ref=tie *FH,"File::Tail",(name=>$name);
     while (<FH>) {
        m/\/sorry\// && hold ($_);
}

Trying to do: If string with "/sorry/" is found in a squid's log file, pass that string as an argument to a "hold" routine.
