It is always a good practice to know the hardware components of your Linux system is running on, this helps you to deal with compatibility issues when it comes to installing packages, drivers on your system.
1. How to View Linux System Information
To know only system name, you can use uname command without any switch will print system information or uname -s command will print the kernel name of your system.
root@root:~# uname Linux
To view your network hostname, use ‘-n’ switch with uname command as shown.
root@root:~# uname -n root
root@root:~# uname -v #1 SMP Debian 4.8.15-1kali1 (2016-12-23)
To get the information about your kernel release, use ‘-r’ switch.
root@root:~# uname -r 4.8.0-kali2-amd64
To print your machine hardware name, use ‘-m’ switch:
root@root:~# uname -m x86_64
All this information can be printed at once by running ‘uname -a’ command as shown below.
root@root:~# uname -a Linux root 4.8.0-kali2-amd64 #1 SMP Debian 4.8.15-1kali1 (2016-12-23) x86_64 GN/Linux Other Useful Commands 1. root@root:~# cat /proc/cpuinfo processor : 0 vendor_id :

2. How to View Linux System Hardware Information
Here you can use the lshw tool to gather vast information about your hardware components such as cpu, disks, memory, usb controllers etc.
lshw is a relatively small tool and there are few options that you can use with it while extracting information. The information provided by lshw gathered form different /proc files.
To install this tool : apt-get install lshw
Note: Do remember that the lshw command executed by superuser (root) or sudo user.
To print information about your Linux system hardware, run this command.
root@root:~# lshw

3. How to View Linux CPU Information
To view information about your CPU, use the lscpu command as it shows information about your CPU architecture such as number of CPU’s, cores, CPU family model, CPU caches, threads, etc from sysfs and /proc/cpuinfo.
root@root:~# lscpu

4. How to Collect Linux Block Device Information
Block devices are storage devices such as hard disks, flash drives etc. lsblk command is used to report information about block devices as follows.
root@root:~# lsblk
NAME MAJ:MIN RM SIZE RO TYPE MOUNTPOINT
sda 8:0 0 465.8G 0 disk
├─sda1 8:1 0 132G 0 part /
├─sda2 8:2 0 1K 0 part
└─sda5 8:5 0 7.7G 0 part [SWAP]
If you want to view all block devices on your system then include the -a option. root@root:~# lsblk -a
5. How to Print USB Controllers Information
The lsusb command is used to report information about USB controllers and all the devices that are connected to them.
root@root:~# lsusb
Bus 004 Device 002: ID 8087:0024 Intel Corp. Integrated Rate Matching Hub
Bus 004 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
Bus 003 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub
Bus 002 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub

Bus 001 Device 002: ID 8087:0024 Intel Corp. Integrated Rate Matching Hub
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
You can use the -v option to generate a detailed information about each USB device. root@root:~# lsusb -v
6. How to Print PCI Devices Information
PCI devices may included usb ports, graphics cards, network adapters etc. The lspci tool is used to generate information concerning all PCI controllers on your system plus the devices that are connected to them.
To print information about PCI devices run the following command.
root@root:~# lspci

7. How to Print SCSI Devices Information
To view all your scsi/sata devices, use the lsscsi command as follows. If you do not have lsscsi tool installed, run the following command to install it.
# sudo apt-get install lsscsi [on Debian derivatives] # yum install lsscsi [On RedHat based systems] # dnf install lsscsi [On Fedora 21+ Onwards] After install, run the lsscsi command as shown:
root@root:~# lsscsi
[1:0:1:0] disk ATA WDC WD5000AAKX-0 1H15 /dev/sda
Use the -s option to show device sizes.
root@root:~# lsscsi -s
[1:0:1:0] disk ATA WDC WD5000AAKX-0 1H15 /dev/sda 500GB
8. How to Print Information about SATA Devices
You can find some information about sata devices on your system as follows using the hdparm utility. In the example below, I used the block device /dev/sda1 which the harddisk on my system.
root@root:~# hdparm /dev/sda1
/dev/sda1:
multcount = 16 (on)
IO_support = 0 (default)
readonly = 0 (off)
readahead = 256 (on)
geometry = 60801/255/63, sectors = 276754432, start = 2048
To print information about device geometry interms of cylinders, heads, sectors, size and the starting offset of the device, use the -g option.
root@root:~# hdparm -g /dev/sda1
/dev/sda1:
geometry = 60801/255/63, sectors = 276754432, start = 2048
9. How to Print Linux File System Information
To gather information about file system partitions, you can use fdisk command. Although the main functionality of fdisk command is to modify file system partitions, it can also be used to view information about the different partitions on your file system.
You can print partition information as follows. Remember to run the command as a superuser or else you may not see any output.
root@root:~# fdisk -l
Disk /dev/sda: 465.8 GiB, 500107862016 bytes, 976773168 sectors
Units: sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
Disklabel type: dos
Disk identifier: 0x1fc835a9
Device Boot Start End Sectors Size Id Type
/dev/sda1 * 2048 276756479 276754432 132G 83 Linux
/dev/sda2 276758526 292970495 16211970 7.7G 5 Extended
/dev/sda5 276758528 292970495 16211968 7.7G 82 Linux swap / Solaris
10. How to Extract Information about Hardware Components
You can also use the dmidecode utility to extract hardware information by reading data from the DMI tables.
To print information about memory, run this command as a superuser.
root@root:~# dmidecode -t memory
# dmidecode 3.0
