Neofetch is a popular open-source command-line system information and logo printing tool for Linux and other Unix-like operating systems. It is used to display detailed system statistics and an ASCII distribution logo when invoked in the terminal.
How Neofetch Works
Neofetch is written purely in Bash scripting language. It collects information about your operating system, hardware, software and displays it in an aesthetic manner in the terminal next to an ASCII image representing your distro.
The ASCII image acts as a visual aid to distinguish between systems. You can customize it to any image of your preference.
Under the hood, Neofetch relies on a number of Linux utilities and scripts to generate system information:
- /proc/ filesystem (kernel data)
- /sys/ filesystem (hardware data)
- df (disk usage)
- top (processes)
- lsmod (kernel modules)
- lspci (PCI devices)
- and many more...It runs these utilities, parses their output, and handles any errors or missing data to prepare the report. This information is then formatted and aligned into a readable output using Bash built-ins:
- printf (formatted printing)
- fold (wrap text)
- column (alignment)
- tput (terminal handling)The default Neofetch output provides the following system details:
- Operating System Name and Version
- Linux Kernel Version
- Uptime
- Total number of Packages
- Shell Info
- Screen Resolution
- DE/WM details
- Theme details
- Icon theme
- Terminal emulator
- CPU model and usage
- GPU model and usage
- Memory usage
- Disk usage summary
With over 50 configurable informational options and output settings, Neofetch allows extensive customization as per the user‘s requirements. You can set preferences to change the location, appearances, color, enabling/disabling of images and text, and more.
Why Use Neofetch?
Here are some of the prime advantages and reasons why many Linux users and developers have Neofetch installed on their systems:
Quick Access to System Stats
Neofetch instantly displays the most relevant system statistics in a visually appealing manner instead of having to scrape through various system files.
According to Statista reports, Ubuntu is the most popular Linux distro among developers at 41%, followed by Mint, Debian and CentOS.
Neofetch can instantly provide version info and environments details on all these distros with no additional setup.
Customization for Personalization
Neofetch is highly customizable, allowing developers to set their preferred data outputs and appearances per project or use case needs.
A survey from over 5800 developers found that over 68% utilize the Bash shell and almost 80% use command-line interfaces frequently.
Neofetch‘s customization aligns perfectly to developer preferences by allowing tailored, aesthetic CLI output as per need.
Lightweight for Minimal Overhead
Being a Bash script, Neofetch contains only about 900 lines of code in a very compact 37KB file size. It has practically zero overhead and executes instantly without any noticeable system resource impact.
According to cybersecurity researcher MalwareBytes, software bloat can negatively impact computer performance. Neofetch avoids this issue due to its lightweight script-based implementation.
Cross-Platform Support
It can run on most UNIX-like systems – Linux, BSD, Minix, Solaris, macOS, iOS and more. The only requirement is Bash 4.0+ availability. This makes Neofetch an ideal utility for developers working across different operating systems.
Reports show that an overwhelming majority of developers use Linux (83%) and about half also utilize macOS (49%). Neofetch enables consistency across these environments.
Installing Neofetch on Popular Distros
Neofetch is available in the default repositories of most mainstream Linux distributions today. This allows quick installation from the command-line:
Debian/Ubuntu
$ sudo apt install neofetchRHEL/CentOS/Fedora
$ sudo dnf install neofetch Arch Linux
$ sudo pacman -S neofetchopenSUSE
$ sudo zypper install neofetchFor other distros or Unix-systems, you may need to use platform-specific package managers like FreeBSD Ports, Macports, Spack, Gentoo ebuilds or source compilation.
Check out Neofetch‘s install guide for environment-specific instructions.
Using Neofetch for Quick System Reporting
Once installed, simply run the neofetch command in your terminal:
$ neofetchThis will display the output screen with your system‘s information and logo of the Linux distribution as ASCII art.
You can redirect the Neofetch output into a text file for easy sharing:
$ neofetch > my_system_report.txtSome developers also alias it for even quicker invocation:
# Shell config
alias fetch="neofetch"
$ fetchYou can pass additional command line options and arguments to customize what gets displayed:
$ neofetch --disable memory # Hide memory
$ neofetch --ascii_colors 4 1 # Set ascii art color palette
$ neofetch --ascii_distro arch # Show a different distro logo
$ neofetch --config off # Use default config
$ neofetch --help # Show usage guideIntegrating Neofetch with Other CLI Tools
Neofetch output integrates seamlessly with other command-line utilities utilized by developers:
Pipe into pipes.sh for animated outputs
neofetch | pipes.shDisplay alongside Bashtop for system monitoring
bashtop & neofetchOutput to Ranger terminal file manager as greeting
Add to Rangers‘ rifle.conf:

Customizing Neofetch for Personalized System Reporting
Part of Neofetch‘s popularity comes from it‘s allowing extensive per-user customization of system outputs.
The default configuration is stored in ~/.config/neofetch/config.conf. This file contains all customizable options related to ascii art, info, formats, appearances, screen layouts and more.
You can directly edit this file to set personal preferences. For example:
# Show memory instead of disk info
disable="disk"
# Use 4 thread CPU output format
cpu_shorthand="on"
processor_shorthand="on"
# Right align info
gap=15The customization wiki contains details on all 150+ available config options.
Some popular aesthetic customizations are:
Display Custom ASCII Art
You can make neofetch show any custom ascii image using w3m-img instead of the default distro logo:
$ neofetch --w3m ~/Pictures/avatar.png --ascii_colors 5 4 3 2Set Info Display Order
Organize the info sequence:
$ neofetch --order memory term shell theme res cpu distro kernelShow Info On Right Side
Flipped layout with ascii art on left:
$ neofetch --gap 50 --reverseThis allows ultimate control to developers for custom reporting aesthetics!
