Help with Grep
Hello,
I m trying to send an email alert when any error is captured in the log file.
The log file is getting updated every second with multiple lines. I'm planning to grep the error message and send the alert email.
I have scheduled the script in cron tab to run for every 5 mins.
But the alert is being sent for historical errors also. How to set the script in such a way that latest email alert is sent for latest error entry in the log file and not historic ones.

log::dispatch::email
Log::Dispatch::Email(3) User Contributed Perl Documentation Log::Dispatch::Email(3)
NAME
Log::Dispatch::Email - Base class for objects that send log messages via email
SYNOPSIS
package Log::Dispatch::Email::MySender
use Log::Dispatch::Email;
use base qw( Log::Dispatch::Email );
sub send_email
{
my $self = shift;
my %p = @_;
# Send email somehow. Message is in $p{message}
}
DESCRIPTION
This module should be used as a base class to implement Log::Dispatch::* objects that send their log messages via email. Implementing a
subclass simply requires the code shown in the SYNOPSIS with a real implementation of the "send_email()" method.
CONSTRUCTOR
The constructor takes the following parameters in addition to the standard parameters documented in Log::Dispatch::Output:
o subject ($)
The subject of the email messages which are sent. Defaults to "$0: log email"
o to ($ or @)
Either a string or a list reference of strings containing email addresses. Required.
o from ($)
A string containing an email address. This is optional and may not work with all mail sending methods.
o buffered (0 or 1)
This determines whether the object sends one email per message it is given or whether it stores them up and sends them all at once.
The default is to buffer messages.
METHODS
o send_email(%p)
This is the method that must be subclassed. For now the only parameter in the hash is 'message'.
o flush
If the object is buffered, then this method will call the "send_email()" method to send the contents of the buffer and then clear the
buffer.
o DESTROY
On destruction, the object will call "flush()" to send any pending email.
