在Debian系统中,你可以使用以下几种方法来显示CPU信息:
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
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

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
