I rather suspect this has already been asked before, however, I've been unable to determine where, so I'll just have to ask again. (Sorry...)

I've started using a custom logging system for a set of online utilitys. This system only uses one file, and does not rotate it. The logfile tends to look something like this:
1015295974;127.0.0.1;1;Viewed Log File
1015296127;127.0.0.1;1;TestJoin added to join queue
1015296134;127.0.0.1;1;Acessed the GuildMaster program.
(in case it matters, that's time,ip,ID,action)

With each line being a different record. I want to allow the webmaster to determine a max filesize for the log, and have the logfile remove lines from the top if it's too big, until it's the right size. Is there any simple means to take lines off of the top of a file without rewriting the entire file? Or better yet, is there any way to tell how big a file will be once a string is added to it?

Thank you
