You could of course do
and my.cheapscript.sh could continue to loop and process whatever...
You'll have to make sure that you insure you are at the latest version of the file you are monitoring since even dynamic files have to be pruned. It depends on how the dynamic log file is being written to....does the process keep it open while it's logging...do an fuser <log-file> to see if there is a process pid associated with it. If so then in you cheap script you can save the pid (before the while loop).
If the file gets renamed or deleted you'll need to check for a new version of the file and the tail will break. You could do this all in a single script file and not have to tail to a script file...perhaps something like
I am not 100 percent sure that's bullet proof but you get the idea.

Hi,
I want to know how we can view two or three logs which are dynamically getting updated from a single/same putty window with tail commnad.
Thanks. (7 Replies)
I would like to monitor logfile for specific keyword and send email once detected. I'm trying out the code here, the script is scheduled to run every minute. Everytime it runs, the same log will be detected and send email. Anyway it can be improved to detect only new logs?

io::async::signal
IO::Async::Signal(3pm) User Contributed Perl Documentation IO::Async::Signal(3pm)NAME
"IO::Async::Signal" - event callback on receipt of a POSIX signal
SYNOPSIS
use IO::Async::Signal;
use IO::Async::Loop;
my $loop = IO::Async::Loop->new;
my $signal = IO::Async::Signal->new(
name => "HUP",
on_receipt => sub {
print "I caught SIGHUP
";
},
);
$loop->add( $signal );
$loop->run;
DESCRIPTION
This subclass of IO::Async::Notifier invokes its callback when a particular POSIX signal is received.
Multiple objects can be added to a "Loop" that all watch for the same signal. The callback functions will all be invoked, in no particular
order.
EVENTS
The following events are invoked, either using subclass methods or CODE references in parameters:
on_receipt
Invoked when the signal is received.
PARAMETERS
The following named parameters may be passed to "new" or "configure":
name => STRING
The name of the signal to watch. This should be a bare name like "TERM". Can only be given at construction time.
on_receipt => CODE
CODE reference for the "on_receipt" event.
Once constructed, the "Signal" will need to be added to the "Loop" before it will work.
