Ubuntu查看硬件配置

1. 查看系统内核

long@pc1:/proc$ uname -a
Linux XPS-15-9560 4.10.0-38-generic #42~16.04.1-Ubuntu SMP Tue Oct 10 16:32:20 UTC 2017 x86_64 x86_64 x86_64 GNU/Linux

2. 查看CPU

long@pc1:/proc$ cat /proc/cpuinfo | grep model\ name
model name  : Intel(R) Core(TM) i7-7700HQ CPU @ 2.80GHz
model name  : Intel(R) Core(TM) i7-7700HQ CPU @ 2.80GHz
model name  : Intel(R) Core(TM) i7-7700HQ CPU @ 2.80GHz
model name  : Intel(R) Core(TM) i7-7700HQ CPU @ 2.80GHz
model name  : Intel(R) Core(TM) i7-7700HQ CPU @ 2.80GHz

3. 查看内存

long@pc1:/proc$ cat /proc/meminfo | grep MemTotal
MemTotal:        7807956 kB

4. 查看显卡

long@pc1:/proc$ lspci | grep 'VGA'
00:02.0 VGA compatible controller: Intel Corporation Device 591b (rev 04)

5. 查看声卡

long@pc1:/proc$ lspci | grep -i 'Audio'
00:1f.3 Audio device: Intel Corporation Device a171 (rev 31)

6. 查看网卡

long@pc1:/proc$ lspci | grep -i 'Network'
02:00.0 Network controller: Qualcomm Atheros QCA6174 802.11ac Wireless Network Adapter (rev 32)

7. 查看硬盘

long@pc1:/proc$ df -lh

另外一个命令

其实就一个命令就搞定了：dmidecode 这个可以看具体的硬件信息，这个命令需要使用sudo

最常用的选项就是用 -t 或者 --type 来限定关键字：

bios, system, baseboard, chassis, processor, memory, cache, connector, slot

这里只介绍memory的检测。
直接上我自己Ubuntu测试的结果：

#sudo dmidecode -t memory
[sudo] password for superuser: 
# dmidecode 3.0
Getting SMBIOS data from sysfs.
SMBIOS 3.0 present.
