Hi

Can someone clarify what exactly logrotating is. IF i have a 1gig apache log file, what would happen to the file size if i rotated it with logrotate?

Would al the data still be there for webalizer to use?

it will copy it over to filename.1 then gzip it up. So you cannot use that log for webalizer. You can set how often you want to rotate and the time limit to keep old logs.
