NAME
arch
, machine
— print architecture
type
SYNOPSIS
arch |
[-ks ] |
machine |
[-a ] |
DESCRIPTION
Thearch
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.
