       uname - print name of current system

       uname [-aimnprsvX]

       uname [-S system_name]

       The uname utility prints information about the current system on the standard output. When
       options are specified, symbols representing one or more	system	characteristics  will  be
       written	to  the  standard  output.  If no options are specified, uname prints the current
       operating system's name. The options print selected information returned by uname(2), sys-
       info(2), or both.

       The following options are supported:

       -a		 Prints basic information currently available from the system.

       -i		 Prints the name of the platform.

       -m		 Prints the machine hardware name (class). Use of this option is discour-
			 aged. Use uname -p instead. See NOTES section below.

       -n		 Prints the nodename (the nodename is the name by  which  the  system  is
			 known to a communications network).

       -p		 Prints the current host's ISA or processor type.

       -r		 Prints the operating system release level.

       -s		 Prints the name of the operating system. This is the default.

       -S system_name	 The  nodename	may  be changed by specifying a system name argument. The
			 system name argument is restricted to SYS_NMLN characters.  SYS_NMLN  is
			 an  implementation  specific  value defined in <sys/utsname.h>. Only the
			 super-user is allowed this capability.  This  change  does  not  persist
			 across  reboots  of  the system. Use sys-unconfig(1M) to change a host's
			 name permanently.

       -v		 Prints the operating system version.

       -X		 Prints expanded system information, one information element per line, as
			 expected by SCO UNIX. The displayed information includes:

			     o	    system  name,  node, release, version, machine, and number of

			     o	    BusType, Serial, and Users (set to "unknown" in Solaris)

			     o	    OEM# and Origin# (set to 0 and 1, respectively)

       Example 1 Printing the OS name and release level

       The following command:

	 example% uname -sr

       prints the operating system name and release level, separated by one SPACE character.

       See environ(5) for descriptions of the following environment  variables	that  affect  the
       execution of uname: LANG, LC_ALL, LC_CTYPE, LC_MESSAGES, and NLSPATH.

       SYSV3	 This  variable is used to override the default behavior of uname. This is neces-
		 sary to make it possible for some INTERACTIVE UNIX Systems and SCO UNIX programs
		 and scripts to work properly. Many scripts use uname to determine the SYSV3 type
		 or the version of the OS to ensure software is compatible with that OS.  Setting
		 SYSV3 to an empty string will make uname print the following default values:

		   nodename nodename 3.2 2 i386

		 The  individual  elements  that  uname  displays can also be modified by setting
		 SYSV3 in the following format:


		 os	     Operating system (IUS or SCO).

		 sysname     System name.

		 node	     Nodename as displayed by the -n option.

		 rel	     Release level as displayed by the -r option.

		 ver	     Version number as displayed by the -v option.

		 mach	     Machine name as displayed by -m option.

		 Do not put spaces between the elements.  If an element is omitted,  the  current
		 system value will be used.

       The following exit values are returned:

       0      Successful completion.

       >0     An error occurred.

       See attributes(5) for descriptions of the following attributes:

       |      ATTRIBUTE TYPE	     |	    ATTRIBUTE VALUE	   |
       |Availability		     |SUNWcsu			   |
       |Interface Stability	     |Standard			   |

       arch(1),  isalist(1),  sys-unconfig(1M), sysinfo(2), uname(2), nodename(4), attributes(5),
       environ(5), standards(5)

       Independent software vendors (ISVs) and others who need to determine detailed characteris-
       tics  of the platform on which their software is either being installed or executed should
       use the uname command.

       To determine the operating system name and release level, use uname -sr. To determine only
       the  operating  system  release	level, use uname -r. Notice that operating system release
       levels are not guaranteed to be in x.y format (such as  5.3,  5.4,  5.5,  and  so  forth);
       future releases could be in the x.y.z format (such as 5.3.1, 5.3.2, 5.4.1, and so forth).

       In SunOS 4.x releases, the arch(1) command was often used to obtain information similar to
       that obtained by using the uname command. The arch(1)  command  output  "sun4"  was  often
       incorrectly  interpreted to signify a SunOS SPARC system. If hardware platform information
       is desired, use uname -sp.

       The arch -k and uname -m commands return equivalent values; however, the use of either  of
       these  commands	by third party programs is discouraged, as is the use of the arch command
       in general. To determine the machine's Instruction  Set	Architecture  (ISA  or	processor
       type), use uname with the -p option.
