SPUG: Parsing Huge Files

[mayank_a at students.iiit.ac.in]

Hi All,

I need to parse often huge files of more than 3GB each, and take out
chunks of data, with a certain delimiter spanning multiple lines.
Mainly I am interested only starting and ending 1000 lines.

Is there a faster execution hook, where I can get last 1000  lines of huge
file, without skipping to the end of file.

I am new to the list, so don't know, whether it's the right place to ask
such question.

Thanks and Regards
Mayank
