ARCH(1)

NAME
arch - display system machine type

SYNOPSIS
arch [ "-k" ]

DESCRIPTION
arch displays the current system architecture type. It tends to be equivilent to "uname -m" (except on SunOS platforms, see NOTES).

OPTIONS
"-k"    Displays kernel architecture on SunOS platforms.

NOTES
SunOS tends to differentiate between kernel and system architecture. uname -m will return kernel architecture. System architecture is the same information except it doesn't include the trailing alpha chars. I.e.: 'sun4m' (kernel) = 'sun4' (system), 'sun3x' = 'sun3', etc, etc.

HISTORY
Perl version rewritten for the Perl Power Tools project from the description of the arch program in OpenBSD.
