It is very easy to get hardware information on Ubuntu in a simple and easy to read format.
The sudo lshw -class input command will print information about any input devices connected to your computer.
┌──[jason@11000000.10101000.00000001.00000011]─[~] └──╼ ╼ $ sudo lshw -class input *-usb:1 description: Keyboard product: OMEN Sequencer vendor: HP physical id: 3 bus info: usb@3:3 version: 0.21 capabilities: usb-2.00 configuration: driver=usbhid maxpower=500mA speed=12Mbit/s *-usb:3 description: Mouse product: G502 HERO Gaming Mouse vendor: Logitech physical id: c bus info: usb@3:c version: 27.03 serial: 017F39783637 capabilities: usb-2.00 configuration: driver=usbhid maxpower=300mA speed=12Mbit/s |
This example will return output in HTML format.

This nice example prints the output in Javascript Object Notation format.
┌──[jason@11000000.10101000.00000001.00000011]─[~] └──╼ ╼ $ sudo lshw -class input -json [ { "id" : "usb:1", "class" : "input", "claimed" : true, "handle" : "USB:3:3", "description" : "Keyboard", "product" : "OMEN Sequencer", "vendor" : "HP", "physid" : "3", "businfo" : "usb@3:3", "version" : "0.21", "configuration" : { "driver" : "usbhid", "maxpower" : "500mA", "speed" : "12Mbit/s" }, "capabilities" : { "usb-2.00" : "USB 2.0" } }, { "id" : "usb:3", "class" : "input", "claimed" : true, "handle" : "USB:3:5", "description" : "Mouse", "product" : "G502 HERO Gaming Mouse", "vendor" : "Logitech", "physid" : "c", "businfo" : "usb@3:c", "version" : "27.03", "serial" : "017F39783637", "configuration" : { "driver" : "usbhid", "maxpower" : "300mA", "speed" : "12Mbit/s" }, "capabilities" : { "usb-2.00" : "USB 2.0" } } ] |
List all of the RAM and memory in your machine.
┌──[jason@11000000.10101000.00000001.00000011]─[~] └──╼ ╼ $ sudo lshw -businfo | grep GiB |
This lists all RAM sticks as well as all hard disk drives that are installed. A very useful command.
Use this example to get network devices information, but strip out serial numbers and other information. This would be useful for sharing on a forum for example.
┌──[jason@11000000.10101000.00000001.00000011]─[~] └──╼ ╼ $ sudo lshw -class network -sanitize |
This is a way to find out when you logged into your Linux machine.
┌──[jason@11000000.10101000.00000001.00000011]─[~] └──╼ ╼ $ lslogins | grep $LOGNAME | awk '{ print $4 }' 07:15 |
That could be useful.
Finally, this is the systemd-analyze utility, this prints the time taken by the system to boot.
┌──[jason@11000000.10101000.00000001.00000011]─[~] └──╼ ╼ $ systemd-analyze Startup finished in 4.312s (kernel) + 2min 341ms (userspace) = 2min 4.653s graphical.target reached after 2min 299ms in userspace |
If you use the blame parameter, this will list the process started by the system upon booting and they will be ranked by the time taken for them to run.
┌──[jason@11000000.10101000.00000001.00000011]─[~] └──╼ ╼ $ systemd-analyze blame | head -n 20 1min 3.226s plymouth-quit-wait.service 17.647s NetworkManager-wait-online.service 17.043s systemd-journal-flush.service 14.785s snapd.seeded.service 13.338s snapd.service 13.298s tor@default.service 10.233s postfix@-.service 10.133s systemd-udev-settle.service 10.105s dev-sdd1.device 10.013s apache2.service 9.440s polkit.service 9.428s networkd-dispatcher.service 9.253s avahi-daemon.service 9.237s NetworkManager.service 9.198s switcheroo-control.service 8.607s thermald.service 8.605s systemd-logind.service 8.556s wpa_supplicant.service 8.026s ssh.service 7.058s rsyslog.service |
You may then see if an unneeded process is slowing the system boot down. But if I had an SSD, it would be a lot faster. Not too bad though.
