How to Use the Command 'fastfetch' (with Examples)

Fastfetch is a powerful and efficient command-line tool designed to quickly display information about your operating system, software configs, and hardware details. It can provide insights into various elements of your system’s architecture or aesthetics with user-defined choices like logos and colors. Fastfetch is known for its speed and flexibility, bringing the essentials of system summary to the terminal without overhead. Whether you’re showcasing your configurations or troubleshooting system details, fastfetch can be a potent choice. Here’s how you can make full use of fastfetch with detailed examples.

Use Case 1: Display System Information

Code:

fastfetch

Motivation:

Understanding the overall configuration and status of your system is crucial, whether you’re troubleshooting or optimizing your setup. Running the basic fastfetch command provides a quick snapshot of your essential system information, saving time you’d spend looking for each detail individually.

Explanation:

• fastfetch: This is the primary command that initiates the fetching and display of information regarding your operating system, software, and hardware. Without any additional flags or options, this command runs with its default settings.

Example Output:

OS: Ubuntu 20.04 LTS x86_64 
Kernel: 5.11.0-37-generic 
Shell: bash 5.0.17 
Resolution: 1920x1080 
DE: GNOME 3.36.8 
CPU: Intel i7-9750H (12) @ 4.500GHz 
GPU: NVIDIA GeForce GTX 1650 Mobile / Max-Q 
Memory: 12281MiB / 15771MiB

Use Case 2: Fetch a Specific Structure

Code:

fastfetch --structure structure

Motivation:

When you want to focus on specific components of your system to understand particular configurations—such as networking, hosting environments, or software dependencies—using the --structure option lets you zero in on exactly what you need. This is particularly useful in tailored reporting scenarios where only certain parts of the system architectures are relevant.

Explanation:

• --structure: This flag allows specifying which structure or component of your system you wish to fetch information on. By targeting a specific area, the output remains clean and relevant.

Example Output:

GPU: NVIDIA GeForce GTX 1650 Mobile / Max-Q

Use Case 3: Load a Custom Configuration File

Code:

fastfetch --load-config path/to/config_file

Motivation:

In environments where uniformity is essential, or when using multiple machines, maintaining a consistent output layout is beneficial. Custom configuration files help automate consistency, ensuring that each system controlled by your team or infrastructure adheres to the same configuration interface.

Explanation:

• --load-config: This option specifies that fastfetch should use a user-defined configuration file, which customizes what information should be retrieved and how it should be displayed.
• path/to/config_file: The path to your custom configuration file which houses your desired display settings.

Example Output:

Custom configuration applied, fetching data...

Use Case 4: Use a Specific Logo

Code:

fastfetch --logo logo

Motivation:

In showcasing or presenting your operating environment, a recognizable logo can enhance the aesthetic appeal and professionalism of the presented information. It can also help quickly identify the OS or major software running on the system.

Explanation:

• --logo: This flag allows selection from an array of logos to be displayed alongside system information.
• logo: Substitute ’logo’ with the specific logo name you want to use. This visually ties the output to the identity of your OS or main software environment.

Example Output:

[Logo of choice] OS: Ubuntu 20.04 LTS

Use Case 5: Display System Information without a Logo

Code:

fastfetch --logo none

Motivation:

In professional settings, or minimalistic environments, removing extraneous graphics can maintain a clean and concise focus on the data itself. This is useful when the textual information is the only aspect needed or desired.

Explanation:

• --logo none: This specifies that no logo should appear with the system information. This option streamlines the presentation to purely textual data.

Example Output:

OS: Ubuntu 20.04 LTS x86_64 
Kernel: 5.11.0-37-generic 
...

Use Case 6: Use a Specific Color for the Keys and Title

Code:

fastfetch --color blue

Motivation:

Color can significantly enhance readability and visual appeal, and using a specific color scheme aids in distinguishing key sections of output, making essential information stand out. This is beneficial in extended outputs or when using the terminal frequently.

Explanation:

• --color: This flag changes the color scheme of keys and titles within the output.
• blue: This is the chosen color used for displaying titles and keys, but it can be substituted with other color names available within fastfetch.

Example Output:

OS: [COLOR=blue] Ubuntu 20.04 LTS x86_64 [COLOR=reset] 
Kernel: [COLOR=blue] 5.11.0-37-generic [COLOR=reset]
...
