Welcome to  Sysctl.

Introduction
The sysctl utility retrieves kernel state and allows processes with appropriate privilege to set kernel state. The state to be retrieved or set is described using a “Management Information Base” (“MIB”) style name, described as a dotted set of components.
With this page we will not replace the man page. But will give some examples.
