There's an API for that... File::ReadBackwards. I've never used it myself, but it appears to do what the documentation states.

Using a file called test.txt located in the same directory as the script itself which looks like this:

f
e
d
c
b
a

...and this example script:

use warnings;
use strict;

use File::ReadBackwards;

my $file = 'test.txt';

my $fh = File::ReadBackwards->new($file) 
  or die "can't read the damned '$file' file!: $!";
 
until ($fh->eof) {
    print $fh->readline;
}

[download]

...I get this output:

a
b
c
d
e
f
