There exist different methods of retrieving system information such as the OS type, kernel version, CPU, RAM, and other details about the host system. One of the handiest tools that you can use to display system information on the terminal is the Neofetch tool.
Written in bash 3.2+, Neofetch is a free and opensource command-line tool that displays system and hardware information in a visually appealing manner. Neofetch shows the very basic information you might need to know such as the type of operating system you are running, screen resolution, the kernel, installed packages, memory, and uptime to mention a few. This information is displayed along with your OS logo.
Neofetch supports over 150 operating systems: from Linux, Windows, and even obscure systems such as AIX, Minix, and Free BSD.
Here at LinuxAPT, as part of our Server Management Services, we regularly help our Customers to perform related Linux System tools configuration queries.
In this context, we shall look into how to install Neofetch on major Linux distributions.
To install Neofetch on Debian and Ubuntu-based distributions, simply run the following command as a sudo user:
$ sudo apt install neofetch
To launch Neofetch, simply run the following command to display the OS and system details:
$ neofetch
To install Neofetch in RHEL and CentOS, first install the EPEL repository with the below command.
For RHEL, add the EPEL repository as follows:
$ sudo dnf install https://dl.fedoraproject.org/pub/epel/epel-release-latest-8.noarch.rpm
For CentOS 8 & Rocky Linux 8, run the command:
$ sudo dnf install epel-release
Once EPEL is installed then install Neofetch with the below command:
$ sudo dnf install neofetch
Then launch Neofetch:
$ neofetch
For Rocky Linux 8, some additional steps are required since Neofetch only display a generic Penguin ASCII art instead of the Rocky Linux logo.
Thankfully, there is an updated Code from Neofetch that now supports Rocky. Therefore, you need to update Neofetch using the updated code as follows:
$ curl -s https://raw.githubusercontent.com/dylanaraps/neofetch/master/neofetch | grep -o Rocky
$ sudo curl -s https://raw.githubusercontent.com/dylanaraps/neofetch/master/neofetch -o /usr/bin/neofetch
Now, you can run the Neofetch command and this time around, you will notice the ASCII has changed to reflect the Rocky Linux logo.
For Fedora 30 and later versions, simply run the following command to install Neofetch:
$ sudo dnf install neofetch
For ArchLinux , use the pacman package manager to install Neofetch:
$ sudo pacman -S neofetch
Finally, for SUSE systems such as OpenSUSE Tumbleweed and Leap, use the zypper package manager to install Neofetch:
$ sudo zypper install neofetch
1. To use Neofetch, you can just enter the neofetch command, with no further options, in terminal:
$ neofetch
2. Want to see the ASCII logo for a different distribution? Use the --ascii_distro option, and specify the name of the distro you wish to see:
$ neofetch --ascii_distro archlinux
3. We can get Neofetch to output even more information. For example, the --de_version option can instruct Neofetch to display the version number of our desktop environment:
$ neofetch --de_version on
4. It's also possible to omit any information you want from the Neofetch output. Use the --disable option, then specify the categories you want to disable:
$ neofetch --disable uptime resolution
5. Neofetch can be used for more than just showing off neat screenshots. It's a slick way to obtain concise system information. For example, just specify the specs you wish to see:
$ neofetch uptime cpu memory
The output will give something like this:
uptime: 3 hours, 34 mins
cpu: Intel i5-5300U (1) @ 2.294GHz
memory: 722MiB / 1987MiB
This article covers different ways of installing Neofetch on major Linux distributions. In fact, Neofetch is a handy tool when you want to display information about the system you are working on. It's mostly useful in tutorials and guides when you want to show your readers the OS and hardware type you are using.
To see what other options you can specify with Neofetch, run the neofetch --help command.
