In this tutorial you are going to learn how to list hardware information in Linux. There are various commands that can be used in Linux to list or display hardware information.
Some of these commands include;
- lscpu
- lsusb
- lsblk
- lspci
- hwinfo
- lshw
- lsmem
- lsscsi
Let us know see how you can use these commands to list hardware information in Linux using the above commands;

6. lshw
This command will display detailed information about several hardware units such as motherboard, CPU, PCI etc. The command needs to be run as root (super user) so as to get all the information i.e.
sudo lshw To display brief information, run the following command
lshw --short
Hardware Lister (lshw) -
usage: lshw [-format] [-options ...]
lshw -version
-version print program version ()
format can be
-html output hardware tree as HTML
-xml output hardware tree as XML
-json output hardware tree as a JSON object
-short output hardware paths
-businfo output bus information
options can be
-class CLASS only show a certain class of hardware
-C CLASS same as '-class CLASS'
-c CLASS same as '-class CLASS'
-disable TEST disable a test (like pci, isapnp, cpuid, etc. )
-enable TEST enable a test (like pci, isapnp, cpuid, etc. )
-quiet don't display status
-sanitize sanitize output (remove sensitive information like serial numbers, etc.)
-numeric output numeric IDs (for PCI, USB, etc.)
-notime exclude volatile attributes (timestamps) from output
7. lsmem
To display memory information, run the following command.
lsmem RANGE SIZE STATE REMOVABLE BLOCK
0x0000000000000000-0x00000000bfffffff 3G online yes 0-23
0x0000000100000000-0x000000013fffffff 1G online yes 32-39
Memory block size: 128M
Total online memory: 4G
Total offline memory: 0B8. lsscsi
Is used to display all scsi/sata devices like hard drives and optical drives. To run it start by installing the lsscsi tool first by running the following command.
sudo apt install lsscsi…and then you can run the command now.
lsscsi[3:0:0:0] cd/dvd NECVMWar VMware SATA CD01 1.00 /dev/sr0
[32:0:0:0] disk VMware, VMware Virtual S 1.0 /dev/sdaTo display device size, run the following command
lsscsi -s [3:0:0:0] cd/dvd NECVMWar VMware SATA CD01 1.00 /dev/sr0 -
[32:0:0:0] disk VMware, VMware Virtual S 1.0 /dev/sda 16.1GBAnd that concludes our guide on how to list hardware information in Linux.
