	A syslog service uses configurable logging rules to determine what to do with the given message, these rules use combinations of facilities and severities. In most cases messages are simply written to a file in the '''/var/log''' directory somewhere but you can do advanced things such as send the messages over the network to a central location. If you want to generate your own log messages for example when you’re writing shell scripts use the '''logger''' command-line utility. To automatically prune files and keep your disks from filling up with old messages use the '''logrotate''' utility.
