UNAME(1)                                                              UNAME(1)

     uname - identify the current IRIX system

     uname [ -snrvmpadR ]

     uname [ -V INSTVERSIONNUM ]

     uname [ -S nodename ]

     uname prints information that identifies the current IRIX system to
     standard output. The string IRIX64 is printed on systems that support
     64-bit addressing (pointers); also see the KERN_POINTERS argument to

     The options cause selected information returned by uname(2) to be

     -a   Behave as though all of the options -mnrsv were specified.

     -m   Print the machine hardware name.  This is the type of CPU board that
          the system is running on, e.g.  IP22.

     -n   Print the hostname or nodename.  The nodename is the name by which
          the system is known to communications networks.

     -p   Print the (informal) name of the current system's instruction set
          architecture.  See the SI_ARCHITECTURE section of sysinfo(2).

     -r   Print the operating system release.  This string begins with one of
          the following forms:  m.n or m.n.a where m is the major release
          number, n is the minor release number and a is the (optional)
          maintenance level of the release; e.g.  3.2 or 3.2.1.

     -R   Print the extended release name, usually the name of a hardware
          specific release.  Implies the -r option.  The string returned will
          be empty (that is, the -r and -R options will produce the same
          output) on the base OS release.  This option shows additional
          information similar to that printed on the CD label for hardware
          specific releases.

     -s   Print the (operating) system name (the default).

     -S nodename
          Change the hostname or nodename to the specified nodename.  This
          changes only the runtime name, and is normally unused.  The
          hostname(1) command is the recommended method of setting this field,
          because it will allow for longer names. hostname uses the contents
          of /etc/sys_id to set the name during system startup.  Only the
          super-user is allowed this capability.

     -v   Print the operating system version.  This is the date and time that
          the operating system was generated, and has the form:  mmddhhmm.

     The -d and -V options decode the inst version-number, a 10-digit integer
     that, if present, is the last field in the release-name string returned
     by `uname -r'.  Alpha and Beta releases have inst version-numbers, final
     releases do not.  This number represents encoded information about the
     origin of the release.

     `uname -d' attempts to report the running system's inst version
     information; if the release has no inst version-number, uname displays an
     error message.

     `uname -V INSTVERSIONNUM' interprets and displays the information encoded
     in INSTVERSIONNUM; if the number is invalid, uname displays an error

     Do not confuse the 8-digit version number returned by `uname -v'--present
     in all releases--with the 10-digit inst version-number.  The two serve
     different--if somewhat overlapping--purposes.
