NAME
       arch - display the architecture of the current host

SYNOPSIS
       arch [-k	| archname]

DESCRIPTION
       arch  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 applica-
       tion architecture.  Use of this command is discouraged; see NOTES  sec-
       tion 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    Display the kernel	architecture, such as  sun4m,  sun4c,  and  so
	     forth.   This defines which specific SunOS	kernel will run	on the
	     machine, and has implications only	for programs  that  depend  on
	     the kernel	explicitly (for	example, ps(1)).

OPERANDS
       The following operand is	supported:

       archname
	     Use   archname  to	determine whether the application binaries for
	     this application  architecture can	run on the current  host  sys-
	     tem. The  archname	must be	a valid	application 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.
