+.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 equivalent to
+.BR "uname -m" .
+
+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)
+.\"
+.\" 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)
