I posted from my phone, I couldn't realistically try this at the time. It is, as I suppose you're suggesting, pretty darn slow. I'd used Tie::File in the past, but not with files this large.

Tie::File remembers the position of the lines it has encountered. Not problem if you want to read lines 100 to 200.

...just be sure not to reference $#array or scalar @array, otherwise you have to wait for the whole file to have been shuffled through memory.

Consuming 1.5GB of ram in the process on my 40e6 line, 3.6GB file. On a Terabyte size file?
