  Add Date : 2018-11-21      
         
         
         
  There are many commands that can be used to view hardware information on Linux system. Some commands can only print out as CPU and memory this particular hardware component information, and some command to view a variety of hardware components.

This tutorial can bring you a quick look at all kinds of information and to view details of the hardware configuration of the device most commonly used commands.

lscpu

lscpu command to view the information processing unit and CPU. This command does not have any other options or other features.

lscpu

hdd_info_lscpu

lspci

lspci is another command-line tool that can be used to list all the details of the PCI bus, and also connected to the PCI bus devices, such as VGA adapter, video card, network adapter, usb port, SATA controllers.

lspci

hdd_info_lspci

You can run the following command to filter out information for a particular device:

lspci -v | grep "VGA" -A 12
Run the above command you can see similar to the following information on the card.

hdd_info_lspci_vga

lshw

lshw is a versatile tool that can list more detailed or summary information about the hardware unit, such as CPU, memory, usb controller, hard disk drives. lshw can extract the relevant information from various "/ proc" file.

lshw -short
You can see the following information by running the above command.

hdd_info_lshw

lsscsi

You can list information such as hard drives and optical drives, etc. scsi / sata device by running the following command:

lsscsi
It will be similar to the following output.

hdd_info_lsscsi

lsusb

lsusb command can list details the USB controller and the USB devices connected to the controller. By default, lsusb command only print out the summary information. Each usb port details can be printed by using the -v parameter.

lsusb
You can see the following output.

hdd_info_lsusb

Inxi

Inxi is a bash script, it is possible to obtain hardware information from multiple sources and command systems, and print out a non-technical person can understand friendly reports.

By default, no inxi installed on Ubuntu. Can be installed by running the following command Inxi:

sudoapt-get install inxi
After installing Inxi, by running the following command can be hardware-related information:

inxi -Fx
It can be similar to the following output.

hdd_info_inxi

df

df command can list the different partitions profiles, mount point, used and available space.

You can add the -H option when using the df command.

df-H
You will get the following output.

hdd_info_df

Free

By using the free command to view, idle and overall the amount of RAM used in the system.

free -m
You see the following output.

hdd_info_free

Dmidecode

dmidecode with other commands are different. The command is to read information from the hardware DMI table.

To view the processor information, run the following command:

sudo dmidecode -t processor

hdd_info_dmi_processor

To view information about the memory, run the following command:

sudo dmidecode -t memory

hdd_info_dmi_memory

To view bios information, run the following command:

sudo dmidecode -t bios
