in reply to Read Some lines in Tera byte file

Isn't this the same question as How to read 1 td file? Perhaps mount the remote disk and use something like Tie::File, or run your script on the remote server.

    use something like Tie::File,

    Please try this yourself--say read the middle line in a 1 or 2GB file--before suggesting it to others.

      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.

      Cheers

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