Thanks. I have something like this in place now. If you look at the
functionality of newsyslog, that's what I'm trying to accomplish.
Newsyslog allows you to specify a file size, time, etc. to determine
when it should to the rotation, as well as how many saved logs to keep.
That's what I'm having trouble with, since I don't seem to be able to
figure out how to make it work the way I want. I may end up having to
learn perl or something, if I can't get this going in shell.
