Linux终端尾部命令

我为此搜索了很多，但找不到任何有用的信息，Linux中“tail-f/var/log/messages”和“tail-f/var/log/maillog”之间有什么区别？

一个简短的列表：

/var/log/messages : General message and system related stuff
/var/log/auth.log : Authenication logs
/var/log/kern.log : Kernel logs
/var/log/cron.log : Crond logs (cron job)
/var/log/maillog : Mail server logs
/var/log/boot.log : System boot log
/var/log/mysqld.log : MySQL database server log file
/var/log/secure or /var/log/auth.log : Authentication log
/var/log/utmp or /var/log/wtmp : Login records file
