1. Compare two date fields on the basis of what?
2. To find a file, use the find command. Check man find for help. Typically, the following is used:
Code:
find ./ -name <file_name>

to find a file recursively in current directory. To replace the filename, use mv command.
3. When you say, "I want to find all the same files", what do you mean?

And, for the example you mentioned "-649595282--649595281-1311131326638#integ_asns_ALF_1YBN_2", you can do something like this:
Code:
echo '-649595282--649595281-1311131326638#integ_asns_ALF_1YBN_2' | cut -d# -f2

This will give you "integ_asns_ALF_1YBN_2" as output.

So how tocompare these.
If value matches I need to return some statement.

Put the two date fields in two separate variables and wrap them in an if-else condition. Not sure if this is what you're looking for.

Code:
#! /bin/bash
date1='Wed Nov 9 09:34:20 EST 2011'
date2='Wed Nov 10 19:14:20 EST 2011'
if [ '$date1' == '$date2' ]
then
    echo "Dates match"
else
    echo "Dates dont match"
fi

it works i guess but not exactly..
how can i store a value of date field in a particular properties file of that in a particular filed.
for eg. directory is Alfdorf-ALF|Wed Nov 9 09:34:20 EST 2011|0
I need to redirect the value of the date value dynamically using script and used it in further program.
This directory is a structure format made in properties file
