Thank you very much for your code. it works as expected. my file is actually maillog file. It's sometimes huge. So File::ReadBackwards is much better. But, the problem is I am trying to insert below lines in to that code.
if (/Passed CLEAN/) { #search string Passed CLEAN
print "$_ \n"; # print ALL lines containing Passed CLEAN
}
But, still no success. I am learning perl. I am still a novice. I googled how to insert it, But, still not lucky.
