1. Keep date in this format for easier numeric comparison: yyyymmddhhmiss (20120220034005). Two such numbers are easier for comparison.
2. If date is in this format: "2012-02-20 03:40:05", how can you compare it with some other date in the same format using > and < symbols?
3. When you say $0 in awk, it refers to the whole line. I see that log.0 file contains lines in this format: "2012-02-18 22:18:06.768 | STATUS:SUCCESS", so you're trying to compare this whole line with $a and $b.
4. You can reduce this line to "2012-02-18 22:18:06" by defining the field separator as "." and taking $1 into account. And further reduce it to "20120218221806" by removing hyphen and colon.
You are Right!!!

Thank you so much ..Scripting is reading the lines..Thanks again

My log file will have only this format 2012-02-18 22:18:06.768...Is it a way that we can compare any two dates...irrespective of the date format in the log file.
Ex format :
1.Feb 19 19:33:09
2.19/FEB/2012 13:55:36
3.2012-02-18 22:18:06.768
Thank You!!!

io::async::test
IO::Async::Test(3pm) User Contributed Perl Documentation IO::Async::Test(3pm)
NAME
"IO::Async::Test" - utility functions for use in test scripts
SYNOPSIS
use Test::More tests => 1;
use IO::Async::Test;
use IO::Async::Loop;
my $loop = IO::Async::Loop->new;
testing_loop( $loop );
my $result;
$loop->do_something(
some => args,
on_done => sub {
$result = the_outcome;
}
);
wait_for { defined $result };
is( $result, what_we_expected, 'The event happened' );
...
my $buffer = "";
my $handle = IO::Handle-> ...
wait_for_stream { length $buffer >= 10 } $handle => $buffer;
is( substr( $buffer, 0, 10, "" ), "0123456789", 'Buffer was correct' );
DESCRIPTION
This module provides utility functions that may be useful when writing test scripts for code which uses "IO::Async" (as well as being used
in the "IO::Async" test scripts themselves).
Test scripts are often synchronous by nature; they are a linear sequence of actions to perform, interspersed with assertions which check
for given conditions. This goes against the very nature of "IO::Async" which, being an asynchronisation framework, does not provide a
linear stepped way of working.
In order to write a test, the "wait_for" function provides a way of synchronising the code, so that a given condition is known to hold,
which would typically signify that some event has occured, the outcome of which can now be tested using the usual testing primitives.
Because the primary purpose of "IO::Async" is to provide IO operations on filehandles, a great many tests will likely be based around
connected pipes or socket handles. The "wait_for_stream" function provides a convenient way to wait for some content to be written through
such a connected stream.
FUNCTIONS
testing_loop( $loop )
Set the "IO::Async::Loop" object which the "wait_for" function will loop on.
wait_for( $condfunc )
Repeatedly call the "loop_once" method on the underlying loop (given to the "testing_loop" function), until the given condition function
callback returns true.
To guard against stalled scripts, if the loop indicates a timeout for 10 consequentive seconds, then an error is thrown.
wait_for_stream( $condfunc, $handle, $buffer )
As "wait_for", but will also watch the given IO handle for readability, and whenever it is readable will read bytes in from it into the
given buffer. The buffer is NOT initialised when the function is entered, in case data remains from a previous call.
$buffer can also be a CODE reference, in which case it will be invoked being passed data read from the handle, whenever it is readable.
