Linux硬件信息命令大全
|
||
================================================================================
|
||
### 硬件信息 ###
|
||
|
||
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
|
||

|
||
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
|
||

|
||
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

||
Swap: 1951 921 1030
|
||
|
||
### 14. dmidecode ###
|
||
|
||
dmidecode命令不同于其他的命令，它是通过读取SMBOIS数据结构（也称为DMI表）中数据来提取硬件信息。
|
||
|
||
# 显示处理器信息
|
||
$ sudo dmidecode -t processor
|
||
|
||
# 显示内存信息
|
||
$ sudo dmidecode -t memory
|
||
|
||
# 显示bios信息
|
||
$ sudo dmidecode -t bios
|
||
|
||
查看man手册获取更多信息。
|
||
|
||
### 15. /proc 文件系统 ###
|
||
|
||
在/proc目录下的许多虚拟文件包含了很多有关硬件参数及配置的信息。
|
||
|
||
CPU、内存信息
|
||
|
||
# cpu信息
|
||
$ cat /proc/cpuinfo
|
||
|

### 总结 ###
|
||
|
||
每一个命令在获取信息的方式会稍微有些不同，在查询某一设备时，你也有可能要结合多个命令才能获取你想要的硬件信息。不过，这些命令都可以在大多数的linux发行版中找到，可以很容易地从默认的仓库中获取安装。
|
||
|
||
在桌面版系统中，还有一个便于使用的图形界面的工具，比如Hardinfo、I-nex就是其中非常流行的工具，他们可以提供多个硬件部件的详细信息。
