Hi Arivoli,

Theres a dirty trick ;) (by running a command).. If u r on a linux machine u can use the tail command .. tail -100 <filename> would give u the last 100 lines of <filename> .. 
(or do a seek and read) 
or u can try this http://code.google.com/p/pytailer/

Regards,
Vimal

Subject: [BangPypers] How to read a file from bottom

Hi everybody,
   i have a log file which will grow everyday, so the size will be nearly 500MB. i am keep on inserting a line one by one in the file.
so the latest one will be in the bottom. I need to get latest 100 lines(lines from bottom). Any idea how to read lines from bottom in a text file?

I tried storing into a list line by line, and iterating from bottom , but it seems to be slow. Is there any better way to do this?

thanks
Arivoli
