Hi,
You can always read a file backwards until you reach a position that was
already processed.
This can be done by using File::ReadBackwards.
Hope that helps

Subject: How to read a very large file??
Hi Guys,
I have a very large file. It may be contain 1lac lines.. also it
length is increased in dynamically..
Each time ( per 5 min) i need to read the contents from file & do some
work .. Suppose i have read the lines for first 5 min then after some
time it reads the same line also , so it take more time & it is a
waste of time..
The code is following,
open FF, "/tmp |" || die "can't access log file\n";
while (<FF>)
{
chomp;
// do some work..
}
close(FF)
Could u help me to solve the pbm??
Thanks,
Siva
