Mac OS X Tiger for Unix Geeks

Chapter 17. System Management Tools

Mac OS X comes with many tools for tweaking and spying on various aspects of your system, including memory, kernel modules, and kernel state variables. Some of these tools come directly from BSD, while others are unique to Mac OS X. Most of the BSD-derived utilities have been filtered through Mach and NeXTSTEP on their way to Mac OS X.

For more details on any of these utilities, see their respective manpages.
