reading partial file content
hi,
I'd like to extract data from very large files (ca 1-2 Mio lines),
and I already know which lines of these files I need.
Is there a way to do it without filling the memory with the whole file content?
The lines I need are randomly distributed within the files.
Thanks,
Marc
