.SH DESCRIPTION
.B Uname
displays the values of a set of strings describing the system.  The options
tell what system values are to be displayed.  First those mandated by
\s-2POSIX\s+2, with example values for Minix-vmd on a 486:
.TP
.B \-s
Name of the Operating System.  (Minix-vmd)
.br
(Printed by default.)
.TP
.B \-n
The node/network name of the machine.  (dinghy.cs.vu.nl)
.TP
.B \-r
Operating system release.  (1.6.25)
.TP
.B \-v
The particular version of this release.  (0.52)
.br
(The revision number is concatenated to the version number.  In this case
it tells you that the kernel was recompiled 52 times.)  The split between
release and version number is somewhat arbitrary.  The version number is
what is often called the "patchlevel."  That's why standard Minix 1.6.25
is release 1.6, version 25.
.TP
.B \-m
The name of the machines hardware.  (i486)
.TP
.B \-a
Same as
.BR \-snrvm .
.PP
.B Uname
lists the values of these options on one line separated by spaces, in the
same order as the usage message shows.
.PP
.B Uname
may be given as many arguments as it has options, it will then try to set
these values system wide.  (This time in option order!)  Only the super-user
may set them, and not even all of them.
.B Uname
may be linked to different names to change its behaviour, using names that
are the same as the names of the struct utsname members described in
.BR uname (2).
Under these new names
.B uname
will display only the given string, except for
.B arch
and
.B hostname
that allow more options.
.PP
Minix specific options:
.TP
.B \-p
Name of the architecture, i.e. the binaries that run on it.  (i386)
.TP
.B \-k
Kernel architecture, i.e. minimum machine requirement.  (i386)
.TP
.B \-h
The more casual name for the machine, normally the nodename with the
domain stripped off.  (dinghy)
.TP
.B \-b
The bus architecture of the machine, i.e. the kind of hardware that your
processor is embedded in.  (ibm)
.PP
Use
.B arch \-a
to see all values.  It shows them in the
.B \-pkmhnrvsb
order used by the "hidden directory" system option.  Note that more values
may be added in the future.
.SH SEE ALSO
.BR uname (2).
.SH NOTES
.B Uname
is normally only linked to
.B arch
and
.BR hostname .
