How to Get Hardware Details from Command Line on Ubuntu
Published: 26 Oct 2021
CPU
cat /proc/cpuinfo | grep 'model name\|cpu family\|processor\|cache size' | sort -u
Here’s an example of the output:
cache size : 12288 KB
cpu cores : 6
cpu family : 6
model name : Intel(R) Core(TM) i7-8700K CPU @ 3.70GHz
processor : 0
processor : 1
processor : 10
processor : 11
processor : 2
processor : 3
processor : 4
processor : 5
processor : 6
processor : 7
processor : 8
processor : 9
- The
cache sizeindicates the L2 memory cache available to the processor. - The
cpu coresrepresents the number of cores cpu familytells you the type of processor you have. In this case, it’s an Intel and placing the value in front of “86” tells us it’s “686” and since it’s a 64-bit chip, you’ll commonly see it represented as “x86-64.”model nameis self-explanatory- The number of
processorlines indicates the number ofthreads. In this case, 12.
Disk
hwinfo --disk | grep 'Device Files'
Note: You may have to install hwinfo
Here’s an example of the output (in this case I have two disks):
Device Files: /dev/nvme0n1, /dev/disk/by-id/nvme-Samsung_SSD_970_PRO_1TB_S462NF0M621968K, /dev/disk/by-path/pci-0000:04:00.0-nvme-1, /dev/disk/by-id/nvme-eui.0025385691b57092
Device Files: /dev/sda, /dev/disk/by-label/disk1, /dev/disk/by-id/wwn-0x5002538e40529604, /dev/disk/by-id/ata-Samsung_SSD_860_EVO_1TB_S3Z8NB0K702696L, /dev/disk/by-uuid/67864506-3ff3-4bc0-bd88-3cdacee5ca46, /dev/disk/by-path/pci-0000:00:17.0-ata-1
Display
sudo lshw -c display | grep 'product\|vendor'
Example output:
product: GP106 [GeForce GTX 1060 6GB]
vendor: NVIDIA Corporation
Memory
sudo dmidecode --type 17 | grep -e 'Speed\|Type:\|Size' | sort -u
Example output:
Configured Memory Speed: 2133 MT/s
Size: 16384 MB
Speed: 2133 MT/s
Type: DDR4
