I've a question to ask:
we can first modify /etc/syslog.conf then "service syslog restart" to make the modification activated. After that, we can use "openlog", "syslog" etc. functions in our program to output the log. My question is, if my program works day and night, the log file may be larger and larger, does syslog supply "log file clean-up" service? Can syslog delete the log file everyday? How can I make the configuration?
