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.


The following list is only an excerpt.

Use sysctl plus the following NAME
