+.Sh NAME
+.Nm sysctl
+.Nd get or set kernel state
+.Sh SYNOPSIS
+.Nm sysctl
+.Op Fl n
+.Ar name ...
+.Nm sysctl
+.Op Fl n
+.Fl w
+.Ar name=value ...
+.Nm sysctl
+.Op Fl n
+.Fl aA
+.Sh DESCRIPTION
+The
+.Nm 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.
+The
+.Fl a
+flag can be used to list all the currently available string or integer values.
+The
+.Fl A
+flag will list all the known MIB names including tables.
+Those with string or integer values will be printed as with the
+.Fl a
+flag; for the table values,
+the name of the utility to retrieve them is given.
+.Pp
+The
+.Fl n
+flag specifies that the printing of the field name should be
+suppressed and that only its value should be output.
+This flag is useful for setting shell variables.
+For example, to save the pagesize in variable psize, use:
+.Bd -literal -offset indent -compact
+set psize=`sysctl -n hw.pagesize`
+.Ed
+.Pp
+If just a MIB style name is given,
+the corresponding value is retrieved.
+If a value is to be set, the
+.Fl w
+flag must be specified and the MIB name followed
+by an equal sign and the new value to be used.
+.Pp
+The proc top-level MIB has a special semantic: it represent per-process values
+and as such may differ from one process to another. The second-level name
+is the pid of the process (in decimal form), or the special word 'curproc'.
+For variables below 'proc.<pid>.rlimit', the integer value may be remplaced
+with the string 'unlimited' if it matches the magic value used to disable
+a limit.
+.Pp
+The information available from
+.Nm sysctl
+consists of integers, strings, and tables.
+The tabular information can only be retrieved by special
+purpose programs such as
+.Nm ps ,
+.Nm systat ,
+and
+.Nm netstat .
+The string and integer information is summarized below.
+For a detailed description of these variable see
+.Xr sysctl 3 .
+The changeable column indicates whether a process with appropriate
+privilege can change the value.
