NAME
       arch - display the architecture of the current host

SYNOPSIS
       arch [-k	| archname]

DESCRIPTION
       The  arch  utility displays the application architecture	of the current
       host system. Due	to extensive historical	use of	this  command  without
       any  options,  all  SunOS 5.x SPARC based systems will return "sun4" as
       their application architecture. Use of this command is discouraged. See
       NOTES section below.

       Systems	can be broadly classified by their architectures, which	define
       what executables	will run on which machines. A distinction can be  made
       between kernel architecture and application architecture	(or, commonly,
       just "architecture"). Machines that run different kernels due to	under-
       lying hardware differences may be able to run the same application pro-
       grams.

OPTIONS
       -k	Displays the kernel architecture, such as sun4u.  This defines
		which  specific	 SunOS kernel will run on the machine, and has
		implications only for programs that depend on the  kernel  ex-
		plicitly (for example, ps(1)).

OPERANDS
       The following operand is	supported:

       archname	       Use archname to determine whether the application bina-
		       ries for	this application architecture can run  on  the
		       current	host system. The  archname must	be a valid ap-
		       plication architecture, such as	sun4,  i86pc,  and  so
		       forth.

		       If  application	binaries  for  archname	can run	on the
		       current host system, TRUE (0) is	 returned.  Otherwise,
		       FALSE (1) is returned.

EXIT STATUS
       The following exit values are returned:

       0	Successful completion.

       >0	An error occurred.

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

       +-----------------------------+-----------------------------+
       |      ATTRIBUTE	TYPE	     |	    ATTRIBUTE VALUE	   |

       |Availability		     |SUNWcsu			   |
       +-----------------------------+-----------------------------+

SEE ALSO
       mach(1),	ps(1), uname(1), attributes(5)

NOTES
       This  command  is provided for compatibility with previous releases and
       its use is discouraged. Instead,	the uname command is recommended.  See
       uname(1)	for usage information.
