Best option: inxi

Inxi is a Linux command line tool designed for use during chat sessions which shows info about your system’s hardware, CPU, drivers, Kernel, processes, memory usage, plus a load more. It has privacy built in so can filter out your personal info such as IP and MAC address. This makes it a good option if you intend to post your system details on the web or share them with others.

CPU, RAM, & Disk Size

To find the type of CPU, amount of RAM, Disk Size, uptime, and what Kernel you’re running all you need to run is inxi. Note that unlike the below example, your output will be colored so it’s easy to read.

CPU: Quad Core Intel Core i7-4710MQ (-MT MCP-) speed/min/max: 898/800/3500 MHz
Kernel: 5.3.0-46-generic x86_64 Up: 2d 12h 22m Mem: 2977.4/7651.8 MiB (38.9%) 
Storage: 894.25 GiB (44.1% used) Procs: 275 Shell: bash 4.4.20

Model & Serial number

Find the model number of your laptop, serial number, motherboard type, and date your machine was made with the -M option (short for ‘Machine’). Note how the serial number has been hidden due to inxi’s built in privacy feature, if you’re not posting the info anywhere public just use sudo inxi -M to reveal the private bits.

# Run this as root to reveal your private serial numbers
[email protected]:~# inxi -M

  Type: Laptop System: LENOVO product: 20FAS04S0D v: ThinkPad T460s

  serial: <superuser/root required> UEFI [Legacy]: LENOVO

Disk size, usage, & model

Use the -d option to get info about your SSD, hard disks, and any storage drives attached to your machine. It’s a quick way to see the make of the disk, the size, and the amount of space remaining.

[email protected]:~# inxi -d

Drives:    Local Storage: total: 238.47 GiB used: 168.26 GiB (70.6%)

More useful inxi commands

Note that not all of these commands have privacy enabled by default so double check before posting it on a public forum. For example: running inxi -i will display both your local IP and WAN IP numbers by default so if you want to keep these private add use inxi -izto enable privacy filtering.

inxi -B		# Battery (charge and condition)
inxi -C		# CPU (more details about the cpu)
inxi -D		# Disk (size and usage of local disks)
inxi -G		# Graphics (Card, driver, resolution)
inxi -i		# IP address (includes local and wide)
inxi -M		# Machine (model number, date)
inxi -s		# Sensors (temps, fan speeds)
inxi -S		# System (distro, kernel)
inxi -t		# Processes (top 5 for CPU and memory)

Option 2: lshw

This one is not as pretty as inxi but it is faster and smaller. It gets info by reading various /proc files and needs to be run as a superuser (even though it works as a regular user but warns you about some output being incomplete).

By default it’ll give you a huge list of everything but you can narrow it down by using the -class option to only show the given class of hardware. It also has a -short option which return fewer details, and a sanitise option -sanitize to remove sensitive info like serial numbers etc.


Find info about your CPU by passing in the -class cpu command into lshw. Leave out the -short option if you want more info.

# Using the -short option here because most of the details are useless to me.
[email protected]:~# lshw -class cpu -short

Other lshw classes

There are way more of these available, find a list of all the classes by running lshw -short.

lshw -short		# list available classes
lshw -class network	# network hardware info (doesn't include IP address)
lshw -class storage	# Hard disk info
lshw -class usb		# USB hardware info

Option 3: ls all the things

If lshw is too much for you then there are a bunch of similar commands each of which show details about specific parts of the system. Here are a couple as examples but I’m sure there are loads more.

lscpu		# CPU info
lsblk		# Hard disks, flash drives ect (aka block devices)
lsusb		# USB buses
lspci		# PCI bus info
lssci		# SCSI info
