-.Os
-.Sh NAME
-.Nm sysctl
-.Nd get or set kernel state
-.Sh SYNOPSIS
-.Nm sysctl
-.Op Fl bdn
-.Ar name ...
-.Nm sysctl
-.Op Fl bn
-.Fl w
-.Ar name=value ...
-.Nm sysctl
-.Op Fl bdn
-.Fl aAX
-.Sh DESCRIPTION
-The
-.Nm
-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.
-.Pp
-The following options are available:
-.Bl -tag -width indent
-.It Fl a
-List all the currently available string or integer values.
-.It Fl A
-List all the known MIB names including opaques.
-Those with string or integer values will be printed as with the
-.Fl a
-flag; for the opaque values,
-information about the format and the length is printed in addition the first
-few bytes is dumped in hex.
-.It Fl X 
-Same as
-.Fl A
-except the entire value of opaque variables is hexdumped.
-.It Fl n
-Specify 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
-.It Fl b
-Force the value of the variable(s) to be output in raw, binary
-format.  No names are printed and no terminating newlines are output.
-This is mostly useful with a single variable.
-.It Fl d
-Display the description rather than the value of the requested
-variable(s).
-.It Fl w Ar name=value ...
-Set the MIB
-.Ar name
-to the new
-.Ar value .
-If just a MIB style
-.Ar name
-is given,
-the corresponding value is retrieved.
-.El
-.Pp
-The information available from
-.Nm
-consists of integers, strings, and opaques.
-.Nm Sysctl
-only knows about a couple of opaque types, and will resort to hexdumps
-for the rest.
-The opaque information is much more useful if retrieved by special
-purpose programs such as
-.Nm ps ,
-.Nm systat ,
-and
-.Nm netstat .
-.Pp
-The string and integer information is summarized below.
-For a detailed description of these variable see
-.Xr sysctl 3 .
-.Pp
-The changeable column indicates whether a process with appropriate
-privilege can change the value.

-.It user.stream_max	integer	no
-.It user.tzname_max	integer	no
-.El
-.Sh EXAMPLES
-For example, to retrieve the maximum number of processes allowed
-in the system, one would use the follow request:
-.Bd -literal -offset indent -compact
-sysctl kern.maxproc
-.Ed
-.Pp
-To set the maximum number of processes allowed
-per uid to 1000, one would use the follow request:
-.Bd -literal -offset indent -compact
-sysctl -w kern.maxprocperuid=1000
-.Ed
-.Pp
-Information about the system clock rate may be obtained with:
-.Bd -literal -offset indent -compact
-sysctl kern.clockrate
-.Ed
-.Pp
-Information about the load average history may be obtained with:
-.Bd -literal -offset indent -compact
-sysctl vm.loadavg
-.Ed
-.Pp
-More variables than these exist, and the best and likely only place 
-to search for their deeper meaning is undoubtedly the source where
-they are defined.

-.Sh SEE ALSO
-.Xr sysctl 3
-.Sh BUGS
-.Nm Sysctl
-presently exploits an undocumented interface to the kernel
-sysctl facility to traverse the sysctl tree and to retrieve format 
-and name information. 
-This correct interface is being thought about for the time being.
-.Sh HISTORY
-.Nm Sysctl
-first appeared in
-.Bx 4.4 .
-.Pp
-In 
-.Fx 2.2 ,
-.Nm
-was significantly remodeled.
