From what i understand Log files are circular fixed-size type..
How do we check this and how do we make one of these file..

Thanks

In general there is no such things about log files. It is completely different if they rotate and/or if they have fixed size. It's great if applications producing a log file have options to set the max size, number etc. of log files. But it depends about which log files you mean.
There are tools like logrotate to keep them circulating etc. or write your own script to handle them.

Log files do not rotate on their own. If you see a log file rotate or rename, it is because a process has intentionally done it.

Have a look in /etc/syslog.conf for some good pointers, e.g. this line:

syslog.debug    /var/log/syslog rotate files 26 time 7d compress
