ARCH(1) BSD Reference Manual ARCH(1)NAME
arch, machine - print architecture type
SYNOPSIS
arch [-ks]
machine [-a]
DESCRIPTION
The arch and machine commands display the machine's architecture in
slightly different ways. arch by default displays the application archi-
tecture, defined by both the operating system and the instruction set ar-
chitecture, while machine displays the kernel architecture (without the
operating system part). Note that both commands output the target archi-
tecture as opposed to uname(1) which describes the host. This is useful
for dynamic discovery of the target architecture in build or configura-
tion scripts needing to work in cross-compilation environments.
The options for arch are as follows:
-k Display the kernel architecture instead of application architec-
ture.
-s Display the chosen architecture in a short form, i.e., without
the operating system prefixed.
The options for machine are as follows:
-a Display the application architecture instead of the kernel archi-
tecture.
