Ubuntu Guide For Windows Users: Manage Log File Size

I'm new to Ubuntu and want to know how does one manage all these log files? They must be taking up a lot of space. I would like to clean them out, in the same way that I can when using Event Viewer in Windows 2000/XP.

While Windows users are familiar with Event Viewer for monitoring application, system, security logs and how to manage or archive log files, administering log files on Ubuntu (or any Linux distribution) is not easily found by new users.

The mechanism for managing log size, archiving (rotation), and deleting is accomplished with a utility called logrotate.
