System environment

Skusal som hladat (zatial len grep-om) .. kde si system nastavuje nasledovne premenne:
BASH_VERSINFO=([0]=“2″ [1]=“05b“ [2]=“0″ [3]=“1″ [4]=“release“ [5]=“powerpc-apple-darwin8.0″)
HOSTTYPE=powerpc
MACHTYPE=powerpc-apple-darwin8.0

rad by som si ich zmenil na i386. Je to mozne niekde prestavit ? Nechapem, preco pouziva PPC verziu, ked moze aj i386 ?

$ file /bin/bash
/bin/bash: Mach-O universal binary with 2 architectures
/bin/bash (for architecture i386): Mach-O executable i386
/bin/bash (for architecture ppc): Mach-O executable ppc
