User Commands arch(1)NAME
arch - display the architecture of the current hostSYNOPSIS
arch [ -k | archname ]DESCRIPTION
arch displays the application architecture of the current host system. Due to extensive historical use of this com- mand 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 "architec- ture"). Machines that run different kernels due to underly- ing hardware differences may be able to run the same appli- cation programs.OPTIONS
-k Display the kernel architecture, such as sun4m, sun4c, and so forth. This defines which specific SunOS ker- nel 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 system. 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
