NAME    [Toc]    [Back]

     uname - identify the current IRIX system

SYNOPSIS    [Toc]    [Back]

     uname [ -snrvmpadR	]

     uname [ -V	INSTVERSIONNUM ]

     uname [ -S	nodename ]

DESCRIPTION    [Toc]    [Back]

     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
     sysconf(1).

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

     -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
     message.

NOTES    [Toc]    [Back]

     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.
