.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
|
|
.Fl f
|
|
flag specifies the name of a file to read and process.
|
|
Blank lines and comments (beginning with
|
|
.Ql # )
|
|
are ignored.
|
|
Line continuations with
|
|
.Ql \e
|
|
are permitted.
|
|
Remaining lines are processed similarly to
|
|
command line arguments of the form
|
|
.Ar name
|
|
or
|
|
.Ar name Ns Li = Ns Ar value .
|
|
The
|
|
.Fl w
|
|
flag is implied by
|
|
.Fl f .
|
|
.Pp
|
|
The
|
|
.Fl q
|
|
flag may be used with
|
|
.Fl f
|
|
and
|
|
.Fl w
|
|
to indicate that nothing should be printed for writes unless an error is
|
|
detected.
|
|
.Pp
|
|
The
|
|
.Ql 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
|
|
.Ql curproc .
|
|
For variables below
|
|
.Ql proc.\*[Lt]pid\*[Gt].rlimit ,
|
|
the integer value may be replaced
|
|
with the string
|
|
.Ql 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.

.Sh EXAMPLES
|
|
For example, to retrieve the maximum number of processes allowed
|
|
in the system, one would use the following request:
|
|
.Bd -literal -offset indent -compact
|
|
sysctl kern.maxproc
|
|
.Ed
|
|
.Pp
|
|
To set the maximum number of processes allowed
|
|
in the system to 1000, one would use the following request:
|
|
.Bd -literal -offset indent -compact
|
|
sysctl -w kern.maxproc=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
|
|
To view the values of the per-process variables of the current shell,
|
|
the request:
|
|
.Bd -literal -offset indent -compact
|
|
sysctl proc.$$
|
|
.Ed
|
|
can be used if the shell interpreter replaces $$ with its pid (this is true
|
|
for most shells).
|
|
.Pp
|
|
To redirect core dumps to the /var/tmp/\*[Lt]username\*[Gt] directory,
|
|
.Bd -literal -offset indent -compact
|
|
sysctl -w proc.$$.corename=/var/tmp/%u/%n.core
|
|
.Ed
|
|
Shall be used.
|
|
.Bd -literal -offset indent -compact
|
|
sysctl -w proc.curproc.corename=/var/tmp/%u/%n.core
|
|
.Ed
|
|
changes the value for the sysctl process itself, and will not have the desired
|
|
effect.
