in thread Read Some lines in Tera byte file

because i said file is in tera bytes, so if my file reading position is nth (ex : 99999999) then it will be difficult to parse all lines and consuming time also.

do we have function in perl like seek?

    Perl has seek as a builtin. It's not gonna help solve the question you asked us, though.

      It might if he's forgotten to mention that his records are fixed length.

        I suppose his lines could all be the same length, or he might have been using the term "line" loosely.

        bhaskar, are your lines/records all the same length? If so, your could calculate the position to which to seek using a simple multiplication.
