Dear List
I have a very large file basically it is logfile generated by sql
loader......... In the production environment this file can have one
million/ two million data. In this file there are 4 particular lines which
i need to extract from this log file.
*Total logical records skipped: 0
Total logical records read: 4830
Total logical records rejected: 51
Total logical records discarded: 4760
*
These four lines stayed at the bottom of the. Now if I use a filehandel to
open the file and stored it contents in an array and after that I make a
search to find these 4 lines then it will take lot of times to get output.
So is there any other way where I dont need to store the file in a array and
I can directly search the file and when I find these lines I can store these
lines in some array or variables. I am pesting part of the file here.
