sys-utils: add arch(1) back to the official tree
This patch add arch(1) back to util-linux source code tree, but the command is not installed by defautl. For more details see "./configure --help". The arch command is deprecated in favor of "uname -m" (coreutils). The latest (6.9+) version of coreutils also supports arch(1) as an alias to "uname -a". Please, if you need arch(1) use the coreutils implementation. Signed-off-by: Karel Zak <kzak@redhat.com>

|

.TH ARCH 1 "4 July 1997" "Linux 2.0" "Linux Programmer's Manual"
|

.SH NAME
|

arch \- print machine architecture
|
||||
.SH SYNOPSIS
|
||||
.B arch
|
||||
.SH DESCRIPTION
|
||||
.B arch
|
||||
is deprecated command since release util-linux 2.13. Use
|
||||
.BR "uname -m"
|
||||
or use
|
||||
.BR arch
|
||||
from the coreutils package.
|
||||
|
||||
On current Linux systems,
|
||||
.B arch
|
||||
prints things such as "i386", "i486", "i586", "alpha", "sparc",
|
||||
"arm", "m68k", "mips", "ppc".
|
||||
.SH SEE ALSO
|
||||
.BR uname (1),
|
||||
.BR uname (2)
|
||||
.SH AVAILABILITY
|
||||
The arch command is part of the util-linux-ng package and is available from
|
||||
ftp://ftp.kernel.org/pub/linux/utils/util-linux-ng/.
|
||||
.\"
|
||||
.\" Details:
|
||||
.\" arch prints the machine part of the system_utsname struct
|
||||
.\" This struct is defined in version.c, and this field is
|
||||
.\" initialized with UTS_MACHINE, which is defined as $ARCH
|
||||
.\" in the main Makefile.
|
||||
.\" That gives the possibilities
|
||||
.\" alpha arm i386 m68k mips ppc sparc sparc64
|
||||
.\"
|
||||
.\" If Makefile is not edited, ARCH is guessed by
|
||||
.\" ARCH := $(shell uname -m | sed -e s/i.86/i386/ -e s/sun4u/sparc64/)
|
||||
.\" Then how come we get these i586 values?
|
||||
.\" Well, the routine check_bugs() does system_utsname.machine[1] = '0' + x86;
|
||||
.\" (called in init/main.c, defined in ./include/asm-i386/bugs.h)
