I just wrote this script and is working very fine:
#!/bin/bash
counter1=0
for i in `ls -ltr | grep -v "total" | grep -v "pre_swh" | awk '{ print $9 ":" $5 }'`;
do
arr_key_old[$counter1]=$i
echo "Counter1 is $counter1 "
echo "Key Old is : ${arr_key_old[$counter1]} "
counter1=`expr $counter1 + 1`
done
echo "Before sleeping"
sleep 120
echo "After sleeping"
counter2=0
for i in `ls -ltr | grep -v "total" | grep -v "pre_swh" | awk '{ print $9 ":" $5 }'`;
do
arr_key_new[$counter2]=$i
echo "Counter2 is $counter2 "
echo "Key new is : ${arr_key_new[$counter2]} "
counter2=`expr $counter2 + 1`
done
counter3=1
for j in `echo ${arr_key_old[*]}`
do
for k in `echo ${arr_key_new[*]}`
do
if [ "$j" = "$k" ]
then
echo " Here testing for old and new : $j is equal to $k"
file_name=`echo $j|awk -F':' '{ print $1 }'`
echo "$counter3 Final file name is $file_name"
counter3=`expr $counter3 + 1`
fi
done
done

LEARN ABOUT PHP
array_flip
ARRAY_FLIP(3) 1 ARRAY_FLIP(3)
array_flip - Exchanges all keys with their associated values in an array
SYNOPSIS
array array_flip (array $array)
DESCRIPTION
array_flip(3) returns an array in flip order, i.e. keys from $array become values and values from $array become keys.
Note that the values of $array need to be valid keys, i.e. they need to be either integer or string. A warning will be emitted if a value
has the wrong type, and the key/value pair in question will not be included in the result.
If a value has several occurrences, the latest key will be used as its value, and all others will be lost.
PARAMETERS
o $array
- An array of key/value pairs to be flipped.
RETURN VALUES
Returns the flipped array on success and NULL on failure.
EXAMPLES
Example #1
array_flip(3) example
<?php
$input = array("oranges", "apples", "pears");
$flipped = array_flip($input);
print_r($flipped);
?>
The above example will output:
Array
(
[oranges] => 0
[apples] => 1
[pears] => 2
)
Example #2
array_flip(3) example : collision
<?php
$input = array("a" => 1, "b" => 1, "c" => 2);
$flipped = array_flip($input);
print_r($flipped);
?>
The above example will output:
Array
(
[1] => b
[2] => c
)
