在Debian系统中,你可以使用以下几种方法来显示CPU信息:

1. 使用 lscpu 命令

lscpu 是一个非常强大的工具,可以显示详细的CPU架构信息。

lscpu

输出示例:

Architecture:          x86_64
CPU op-mode(s):        32-bit, 64-bit
Byte Order:            Little Endian
CPU(s):                4
On-line CPU(s) list:   0-3
Thread(s) per core:    1
Core(s) per socket:    4
Socket(s):             1
NUMA node(s):          1
Vendor ID:             GenuineIntel
CPU family:            6
Model:                 158
Stepping:              9
CPU MHz:               2400.000
BogoMIPS:              4798.00
Virtualization:        VT-x
L1d cache:             32K
L1i cache:             32K
L2 cache:              256K
L3 cache:              4096K
NUMA node0 CPU(s):     0-3

2. 使用 lshw 命令

lshw 是一个硬件信息工具,可以显示详细的硬件配置信息,包括CPU。

首先,你需要安装 lshw

sudo apt update
sudo apt install lshw

然后运行 lshw 并过滤CPU信息:

sudo lshw -class processor

输出示例:

  *-processor

       configuration: cores=4 enabledcores=4 threads=4

3. 使用 dmidecode 命令

dmidecode 是一个直接从DMI(Desktop Management Interface)读取硬件信息的工具。

首先,你需要安装 dmidecode

sudo apt update
sudo apt install dmidecode

然后运行 dmidecode 并过滤CPU信息:

sudo dmidecode -t processor

输出示例:

# dmidecode 3.2
Getting SMBIOS data from sysfs.
SMBIOS 2.8 present.

Handle 0x001B, DMI type 4, 42 bytes
