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 architecture, defined by both the operating system and the
instruction set architecture, while machine displays
the kernel architecture (without the operating system part). Note that both
commands output the target architecture as opposed to
uname(1)
which describes the host. This is useful for dynamic discovery of the target
architecture in build or configuration scripts needing to work in
cross-compilation environments.
The options for arch are as follows:
-k- Display the kernel architecture instead of application architecture.
-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 architecture.
