hwinfo is a hardware information tool that can be used to analyze the hardware on a computer and display detailed information about various hardware components in a human readable format.
It reports information about CPU, RAM, keyboard, mouse, graphics card, sound, storage, network interface, disk, partition, bios, and bridge, etc,.
This tool could display detailed information like lshw, dmidecode, inxi and other tools.
The hwinfo libhd library uses libhd.so
to gather hardware information on the system.
This tool was specifically designed for the openSUSE system, but later other distributions added the tool to their official repository, as it provided better information about computer hardware.
If you are looking for other alternatives, read the following articles as well.
- Dmidecode – A Best Tool to Get System Hardware Information on Linux
- inxi – A Great Tool for Checking Hardware Information on Linux
- LSHW (Hardware Lister) – A Nifty Tool To Get A Hardware Information On Linux
The hwinfo utility displays the following information.
- CPU : manufacturer, model, frequency
- Motherboard : manufacturer, model, BIOS version, on-board controller
- RAM : RAM size, RAM type (FP, EDO, SDRAM, DDRAM)
- Hard disk controller : SCSI, IDE, on-board/card, model, BIOS version, chipset
- Hard disks : type, manufacturer, model, size, bus system (SCSI, IDE), partitioning
- CD-ROM drives : type, manufacturer, model, speed, internal/external, parallel port?
- Other media : CD writer, streamer (model, manufacturer, SCSI/EIDE/floppy streamer, capacity), ZIP drives, Jaz drives, MO drives, flopticals
- Graphics card : model, manufacturer, chipset, memory (DRAM, VRAM), memory size
- Other peripherals : printer, parallel ports, serial ports, modem, ISDN card
1) How To Install hwinfo on Linux
The hwinfo package is available in most Linux distributions repository and can be easily installed with the help of the package manager.
For Fedora/RHEL 8/CentOS 8
systems, use DNF Command to install hwinfo.
Make sure that you should enable the EPEL repository before running the DNF command on RHEL/CentOS systems because the hwinfo package is not available in the distribution official repository.
$ sudo dnf install hwinfo
For Debian/Ubuntu
systems, use APT-GET Command or APT Command to install hwinfo.
$ sudo apt install hwinfo
For Arch Linux
based systems, use Pacman Command to install hwinfo.
$ sudo pacman -S hwinfo
For RHEL/CentOS
systems, use YUM Command to install hwinfo.
Make sure that you should enable the EPEL repository before running the DNF command on RHEL/CentOS systems because the hwinfo package is not available in the distribution official repository.
$ sudo yum install hwinfo
For openSUSE Leap
system, use Zypper Command to install hwinfo.
$ sudo zypper install hwinfo
General Syntax for hwinfo The following is the general syntax for hwinfo.
hwinfo [OPTIONS] [HARDWARE_ITEM]
List of available hardware items for the hwinfo tool It provides a number of hardware items to separate output from your systems.
all, arch, bios, block, bluetooth, braille, bridge, camera, cdrom, chipcard, cpu, disk, dsl, dvb, fingerprint, floppy, framebuffer, gfxcard, hub, ide, isapnp, isdn, joystick, keyboard, memory, modem, monitor, mouse, netcard, network, partition, pci, pcmcia, pcmcia-ctrl, pppoe, printer, redasd, reallyall, scanner, scsi, smp, sound, storage-ctrl, sys, tape, tv, uml, usb, usb-ctrl, vbe, wlan, xen, zip
2) How to Display All Hardware Information on Linux Using the hwinfo Command
Run the hwinfo
command without any argument, which display detailed information about all hardware units but it would be very difficult to understand, as it’s showing in depth details about hardware components.
Also, you can give --all
option and both are showing the same results.
