Hi Monks, I am trying to print last 10 lines from a file but hitting a strange problem. Can you please suggest what is wrong? 
more last_ten.pl
#! /usr/bin/perl -w

use strict;
use File::ReadBackwards;
use diagnostics;

open my $read_log_file, '<', '/home/jay/my_perl_programs/log.txt' or d
+ie $!;
open my $output_file, '>', '/home/jay/my_perl_programs/log_output.txt'
+ or die $!;
my @log_last_ten;
my $log_backwards = File::ReadBackwards->new($read_log_file) or die $!
+;

while (defined(my $log_lines = $log_backwards->readline)) {
   unshift @log_last_ten, $log_lines;
   last if @log_last_ten >= 10;
}

print $output_file "\n----------------------Last 10 Lines from log fil
+e------------------------------\n";
for (@log_last_ten){
print $output_file $_;
}

close $read_log_file;
close $output_file;

The error is:

$ perl last_ten.pl

Uncaught exception from user code: No such file or directory at last_ten.pl line 10. at last_ten.pl line 10

$

This same code works if I change the line:

open my $read_log_file, '<', '/home/jay/my_perl_programs/log.txt' or die $!;

To:

open my $read_log_file='/home/jay/my_perl_programs/log.txt';

Regards

Jay
