Loading a part of the file to array using Tie::File

ansh007 has asked for the wisdom of the Perl Monks concerning the following question:

I am extremely new to perl and working on my 1st perl code. I am stuck at a point, where I need to read a part of a file using Tie::File;

My Old code:

open(LOG_READ,"cat $InLogFilePath|tail -n +$InStartLineNumber|") || di
+e "can not open file :$!";
my @all_lines = <LOG_READ> ;
close (LOG_READ);
for (@all_lines) {.. }

But this could eat a lot of memory, as the files are huge. So I found Tie::File online, that happens not to load arrays in memory. 1st question, is that correct ?

If yes, I get:

tie @array, 'Tie::File', $filename or die ...;

But I do not want to read the whole file. Let's say I want to read from line number 100 till end. How do I do it, using Tie::File ? something similar to:

tie @array, 'Tie::File', "cat $InLogFilePath|tail -n +$InStartLineNumber" or die ...;

Looking forward to your help monks :)
