Linux系统查询硬件信息命令大全

《Linux系统查询硬件信息命令大全》要点：
本文介绍了Linux系统查询硬件信息命令大全，希望对您有用。如果有疑问，可以联系我们。

在linux系统中,有很多命令可以用于查询主机的硬件信息,有些命令仅仅针对于特定的硬件部件,比如cpu,内存等,而有些命令可以查询很多的硬件信息.

这篇帖子简单地带大家了解一下最常用的查询各种硬件信息的命令,其中包括lscpu,hwinfo,lshw,dmidecode,lspci等等.

1. lscpu
lscpu命令可以用来查询处理器cpu的详细信息,只需要简单地输入lscpu即可,如下所示,它本身也没有提供更多选项和功能可供选择.
$ lscpu
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: 23
Stepping: 10
CPU MHz: 1998.000
BogoMIPS: 5302.48
Virtualization: VT-x
L1d cache: 32K
L1i cache: 32K
L2 cache: 2048K
NUMA node0 CPU(s): 0-3

2. lshw – 显示硬件信息列表
这个命令用途广泛,它可以根据你的需求以详细或概要的形式列出许多个不同硬件的参数信息,其中包括cpu,内存,磁盘,usb控制器,网卡等等,lshw实质上是从/proc文件目录下的不同文件中提取对应的硬件信息.
$ sudo lshw -short
