Faith (faith@cs.unc.edu) .\" Public domain: may be freely distributed. .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 package and is available from ftp://ftp.kernel.org/pub/linux/utils/util-linux/. .\" .\" 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)
