I notice that afterwhile my files in /var/log get kind of big. Mainly
debug, messages and syslog. If I delete them, then nothing else is
logged until I re-boot. I read through the man pages and am not quite
able to figure out how to be able to delete these files when they get
too large, but yet still have message written to these log files.
Thanks in advance.

Just open 'em up in emacs or pico or vi or whatever your favorite editor
is,  kill everything but the last two day's messages (or whatever you want
to keep) and close 'em up again.  You can't delete 'em,  because then the
processes (like syslogd) that write to those files think they're already
open ... just make 'em smaller.  Heck,  you could even set up a crontab
entry to do this once a week:

tail -100 /var/log/messages > /var/log/messages.new
rm /var/log/messages
mv /var/log/messages.new /var/log/message

(There are probably a hundred better ways to do this,  but it serves as an
example).

    for x in messages debug syslog;do
        mv /var/log/$x /var/log/o.$x
        touch /var/log/$x
    done
    killall -HUP syslogd

I use
        : > /var/log/messages

to cut down the file to 0 bytes. Logging is not interruptet. I don't
know if it works in a net two but I guess it does.
