Hi Corion,

I am doing this just as a exercise to check memory usage by the system. Please find below my code snippet, 
open FILE,$input_file or die $!;

my @data;

while(<FILE>){
push(@data,$_);
}
close FILE;

[download]
The file i am reading is 2 Gb in size.
In this scenario, the total memory usage should be around 2Gb or something about 4 Gb. My system shows about 3.8 Gb of memory usage.
Does variable FILE also stores the full file in memory and again my array is having the full file.

Is this acceptable. Let me know your inputs.

Thanks,
Manu
