Hi Yogesh,
Thanks for your valuable input, and Thanks for reply on it.
I have included the sugeestion , you told me, But When i run it , i am not getting any data, which i want, but the comment from the file.
Here is the Modified Code :
===========================
#!/bin/bash
FROM_DATE="04/05/2008"
TO_DATE="06/05/2008"
perl -ne 'print if ( $_ >= $ENV{'FROM_DATE'} && $_ <= $ENV{'TO_DATE'} )' monitor.audit
exit
=====================================
The output is only the commented line
#Memory Usage
#Check the Availability
#Disk Monitor
#Load Monitor
#Memory Usage
#Check the Availability
The file monitor.audit data

PPERL(1p) User Contributed Perl Documentation PPERL(1p)
NAME
PPerl - Make perl scripts persistent in memory
SYNOPSIS
$ pperl foo.pl
DESCRIPTION
This program turns ordinary perl scripts into long running daemons, making subsequent executions extremely fast. It forks several processes
for each script, allowing many processes to call the script at once.
It works a lot like SpeedyCGI, but is written a little differently. I didn't use the SpeedyCGI codebase, because I couldn't get it to
compile, and needed something ASAP.
The easiest way to use this is to change your shebang line from:
#!/usr/bin/perl -w
To use pperl instead:
#!/usr/bin/pperl -w
WARNINGS
Like other persistent environments, this one has problems with things like BEGIN blocks, global variables, etc. So beware, and try checking
the mod_perl guide at http://perl.apache.org/guide/ for lots of information that applies to many persistent perl environments.
Parameters
$ pperl <perl params> -- <pperl params> scriptname <script params>
The perl params are sent to the perl binary the first time it is started up. See perlrun for details.
The pperl params control how pperl works. Try -h for an overview.
The script params are passed to the script on every invocation. The script also gets any current environment variables, the current working
directory, and everything on STDIN.
Killing
In order to kill a currently running PPerl process, use:
pperl -- -k <scriptname>
You need to make sure the path to the script is the same as when it was invoked.
Alternatively look for a .pid file for the script in your tmp directory, and kill (with SIGINT) the process with that PID.
ENVIRONMENT
pperl uses the PPERL_TMP_PATH environment variable to determine the directory where to store the files used for inter-process
communication. By default, the subdirectory .pperl of the user's home directory is used.
BUGS
The process does not reload when the script or modules change.
$^S is not represented identically with respect to perl, since your script will be run within an eval block
