DO NOT USE cp WITH LOG FILES. ONLY use mv, only use it on the same
partition and then touch the new log files. better still there exist
log rotation programs that you should use instead. some services
might need a HUP signal (kill -1) to restart logging.
again, look at log rotation programs. using cp on a log file can lose
some of your logs.
