Hit Super (Start button in windows) , Type and and open System Monitor.

For full details system information use HardInfo : Click to install.

HardInfo can display information about both your system's hardware and operating system.

for command line solutions, you can use the command lshw.

Install it if needed:

sudo apt-get install lshw

then run something like

sudo lshw -html > mySpecs.html

then check the html file.

Just

lshw | less

Comment : lshw-> ls(list) hw(hardware)

should give you what you need. On ec2 14.04 I found it pre installed so I am going to assume its part of Ubuntu 14.04 package now and you do not need to exclusively install it

WEB UPD8 has a detail guide on this topic.

How To Get Hardware Information In Linux | Web Upd8: Ubuntu / Linux blog

In short, you could use lshw (command-line or gtk), hardinfo, sysinfo to get what you want.

If you cannot install lshw, you can try the following:

• lscpu: list CPU and processor info
• hwinfo: generic hardware information
• lspci: PCI busses, including graphics card, network adapter
• lsblk: list block devices (storate and partitions)
• df -h: disk free
• free -h: total, free, used RAM

inxi is a command line tool that can be used to find the complete system and hardware details. The inxi command below will show you all the possible system and hardware information on Linux:

inxi -Fxz

run sudo lshw -html > server_specs.html the html result is well structured and easy to find information.

also you can use sudo lshw -C {required_type} to see result for your required specification. for example sudo lshw -C memory

A user on the Ubuntu Forums (MAFoElffen) has created a system-info script for the official Ubuntu Forums.

This script uses various system commands (such as lscpu, hwinfo, lspci, lsblk etc.) to generate a detailed report of all relevant information.

The script can be installed and run by going to the directory where you want to install the script, and then run the following:

wget -N -t 5 -T 10 https://github.com/UbuntuForums/system-info/raw/main/system-info && \
chmod +x system-info && \
./system-info

This will download the script, make it executable, and then run it.

From the official description on the Github page:

• Creates the file system-info.txt at the base of the user's home directory.
• Masks all sensitive info, like IP addresses, MAC addresses, Full FQDN and Serial numbers, automatically in a meaningful way.
• The script displays the report results within the 'less' utility to review the results, one screen at a time. To navigate from there, press the space bar, left, right, up, down, page up or page down keys to navigate. If in a graphical terminal session, you can also use mouse navigation. Press the "q" key to exit "less" and continue. It will print the final report and offer to upload to pastebin site.
• Offers to post the results to the Ubuntu pastebinit provider if that program is installed, and a sufficiently reliable internet connection is available. This is the easiest way to share the sanitized results with the Ubuntu Community for support. After succssful upload to the pastebin, it will both display and log the URL of the uploaded report (~/system-info-link.log), for you to copy and paste in your post on the Ubuntu Forums.
• Future versions may have an option to create the archive system-info.tar.gz if the report exceeds 19.5 kB in size.

Running this script is advised before diagnosing system issue on the Ubuntu Forum, and it could also find a similar use here.

Go to System Settings. Then Go to Details.
