What is the Linux command to find out hardware info?
Here is a list of commands to check hardware on Linux. Note that not all commands are available on all distributions. It is better to launch then as root (or via sudo) to get all the information.
Command: lscpu
Command: lshal
- Require HAL (Hardware Abstraction Layer) to be installed
- List all hardware visible by HAL
Command: lshw
- Available on Ubuntu based distributions by default, and Debian in the main repo
- Available in the Fedora repositories
- Uses many inputs to detect all hardware: Kernel, HAL, DMI, etc.
- As a neat ‘-html’ switch that generates hardware reports
- Check more on this page
Command: lspci
- Standard command
- List all hardware connected to the PCI bus as detected by the kernel
Command: lsusb
- Standard command
- List all hardware connected to the USB buses as detected by the kernel
Command: dmidecode
- Standard command
- Get the source information from the DMI (a kind of BIOS interface)
- List all hardware as reported by the DMI interface
I am a co-developer of a utility that is making its way into several distributions. The tool is called inxi. It is a bash script that does what all the other answers here suggest in one easy command. Check it out.
To use it, simply go to a terminal and type ‘inxi -F’ and it will display a full (-F) system information output. ‘inxi -h’ will show more options. It was originally made for IRC troubleshooting, so it works in almost every IRC client (and comes bundled in some).
Though I don’t develop on this tool any more. I still highly recommend it. I still use it. The code was changed over to Perl at some point. I don’t know of many distros that don’t have it in their repositories either.
Here is a link to various Linux commands for what you want:
Specifically, you’re looking for commands like:
cat /proc/cpuinfo free -m cat /proc/version And, just to add my two cents worth, I would also try
Before using the full comand, you might perhaps try the short version,
which might already provide the info you are searching for. The fll version is very rich in details, so it is probably best called with
And, by the way, a convenient condensed form of the info provided by lshw can be obtained by means of
with easily readable output:

Depeding on the specific distro you are on, most of these commands may need to be installed (apt-get install, yum, pacman, . )
