Linux İşletim Sisteminde İşlemci Bilgileri

Linux işletim sisteminde işlemci bilgilerini elde etmek için;

1. lshw -class processor

2. lscpu

3. cat /proc/cpuinfo

Aşağıdaki betik de kullalabilir.

#!/bin/bash

CAT="/bin/cat"
GR="/bin/grep"
SORT="/bin/sort"
WC="/usr/bin/wc"
UQ="/usr/bin/uniq"
CUT="/bin/cut"
TR="/usr/bin/tr"

# HyperTread YES/NO
