The usage and performance of a system depend on its specifications.
What kind of processor it has? Which version of the operating system runs? How much disk space is left?
You may require these parameters during the installation or configuration of different software.
Here at LinuxAPT, as part of our Server Management Services, we regularly help our Customers to perform Ubuntu Linux related Queries and configuration tasks.
In this context, we shall look into how you can check system and hardware details using command-line and GUI in Ubuntu 20.04 (Focal Fossa).
1. Using Command-Line to check system and hardware details
a. System-Specific Information
All information about the system can be printed using the following command in the terminal:
$ uname -a
The information has following meanings.
i. Name of the kernel (-s): Linux
ii. Name of the host (-n): linuxapt
iii. Kernel release (-r): 5.4.0-54-generic #60-Ubuntu SMP
iv. CPU architecture (-m): x86_64
v. Operating system (-i): GNU/Linux
Options along with the command can be used to print individual parameters. For example, the kernel release can be printed using the following command:
$ uname -r
b. Distribution-Specific Information
All the Linux distribution information can be viewed by typing in the following command.
$ lsb_release -a
The information presented here consists of important information in the following order:
i. Version (not shown as lsb-core package is not installed): No ii. LSB modules are available.
iii. Distributor ID (-i): Ubuntu
iv. Description of distribution (-d): Ubuntu 20.04.1 LTS
v. Release number of the distribution (-r): Release: 20.04
vi. Codename of the distribution (-c): focal
Individual parameters can also be obtained using respective arguments (in brackets).
For example, release number can be obtained using the following command:
$ lsb_release –r
c. Disk Space Information
The primary purpose of df command is to report file system disk space usage.
We will be using this utility to find used, available and the total space of the disk.
$ df –h /
2. Using GUI
i. Press the super (windows) key. Search will appear.
ii. Type in Settings. The settings application will appear.
iii. Open the application by clicking on it.
iv. Scroll down the sidebar.
v. You will now see the menu entities.
vi. Click on About.
vii. A window containing system information will appear.
a. System-Specific Information
Here, you will see the system-specific information with the following information:
i. Device Name: linuxapt
ii. Memory: 1.9GiB
iii. Processor: Intel® Core™ i7-2620M CPU @ 2.70GHz × 2
iv. OS Type: 64-bit
b. Distribution-Specific Information
Here, you will see the window showing the distribution-specific information:
i. OS Name: Ubuntu 20.04 LTS
ii. GNOME Version: 3.36.3
iii. Windowing System: X11
c. Disk Space Information
For example, in our case the window shows disk capacity to be 17.2 GB.
