Hello,
Since you are having the whole file in an array.
1. Keep an index to specify the current line read
2. Once you found the desired string, you have the index also. So
you can
decrement the index and get the lines.
$inex = 0;
foreach $line (@lines) {
$index++;
if($line =~ m/

Hi All,
The below code helps in reading a file in reverse:
use strict;
use warning;

Can you please help me with a small piece of code for the same logic which
you mentioned?
