FreeBSD 查看CPUINFO

linux下的cat /proc/cpuinfo在bsd下没法用，替换的是

[[email protected] /]#dmesg | grep -i CPU

CPU: Intel(R) Xeon(TM) CPU 3.20GHz (3204.40-MHz 686-class CPU)

Hyperthreading: 2 logical CPUs

FreeBSD/SMP: Multiprocessor System Detected: 4 CPUs

cpu0 (BSP): APIC ID: 0

cpu1 (AP): APIC ID: 1

cpu2 (AP): APIC ID: 6

cpu3 (AP): APIC ID: 7

cpu0: on acpi0

acpi_throttle0: on cpu0

cpu1: on acpi0

cpu2: on acpi0

cpu3: on acpi0

SMP: AP CPU #3 Launched!

SMP: AP CPU #1 Launched!

SMP: AP CPU #2 Launched!

还可以：

[ [email protected] /proc]#sysctl -a | grep -i cpu

甚至还能：

sysctl -a | egrep -i 'hw.machine|hw.model|hw.ncpu'
