How to Manage GNOME Extensions Using 'gnome-extensions' (with examples)

The ‘gnome-extensions’ command allows users to manage GNOME Shell extensions directly from the terminal. It provides a suite of subcommands to list, view information, enable, disable, uninstall extensions, and more. GNOME extensions add custom features and functionality to the GNOME desktop environment, enabling users to personalize their user experience according to their needs.

List all the installed extensions

Code:

gnome-extensions list

Motivation:

Listing all installed GNOME extensions helps users to have an overview of which extensions are currently available on their system. This can be particularly useful for troubleshooting, updating extensions, or determining if a desired functionality requires installation. Having a definitive list of all installed extensions aids in system audits to ensure that only necessary and safe extensions are in use.

Explanation:

• gnome-extensions: The base command used for managing GNOME Shell extensions.
• list: A subcommand that tells the system to enumerate and display all extensions that are currently installed, whether enabled or disabled.

Example Output:

ext1@domain.com
ext2@domain.com
ext3@domain.com

Display information about a specific extension

Code:

gnome-extensions info "extension_id"

Motivation:

Getting detailed information about a specific GNOME extension helps users understand its functionality, author, version, and any dependencies or permissions it requires. This information can be crucial for users reviewing the safety and purpose of the extensions they have installed. It is also helpful when troubleshooting to identify version discrepancies or potential update details.

Explanation:

• gnome-extensions: The core command for GNOME Shell extension management.
• info: A subcommand used to gather and print detailed information about a specific extension.
• "extension_id": The unique identifier of the extension. It usually follows a format like “name@domain.com ”.

Example Output:

Name: Sample Extension
Description: This is a sample GNOME extension for demonstration purposes.
Version: 1.0
Author: Developer Name

Enable a specific extension

Code:

gnome-extensions enable "extension_id"

Motivation:

Enabling a GNOME extension activates its functionality, allowing users to utilize the features and changes it provides to the GNOME desktop. This is essential when users have recently installed extensions that are disabled by default or have previously disabled extensions that they want to use again.

Explanation:

• gnome-extensions: The primary command for managing GNOME extensions.
• enable: The subcommand to activate a specific extension.
• "extension_id": Refers to the unique identifier of the extension that needs to be enabled.

Example Output:

There is typically no output when enabling an extension, but any errors or confirmation messages will be displayed.

Disable a specific extension

Code:

gnome-extensions disable "extension_id"

Motivation:

Disabling an extension can be necessary when a user wants to stop using certain features or if an extension causes issues with the desktop environment. Disabling rather than uninstalling allows users to easily re-enable the extension if they wish to use it in the future without reinstallation.

Explanation:

• gnome-extensions: The primary command leveraged for handling GNOME Shell extensions.
• disable: The subcommand used to deactivate a specific extension without removing it.
• "extension_id": The unique identifier for the extension that you want to disable.

Example Output:

Disabling an extension usually results in no direct output, though any issues or confirmations will be displayed.

Uninstall a specific extension

Code:

gnome-extensions uninstall "extension_id"

Motivation:

Uninstalling an extension is useful for users who want to permanently remove unnecessary, outdated, or potentially harmful extensions from their system. This action helps maintain a clean and efficient desktop environment by freeing up resources and reducing potential vulnerability exposure.

Explanation:

• gnome-extensions: The command for managing GNOME Shell extensions.
• uninstall: The subcommand for removing an extension completely from the system.
• "extension_id": The identifier of the extension being removed.

Example Output:

Uninstallation typically produces minimal output. It will notify the user only if there are errors or confirmations required.

Display help for a specific subcommand (like list)

Code:

gnome-extensions help list

Motivation:

Consulting help for specific subcommands assists users in understanding their options, syntax, and additional information needed to execute commands correctly. This is especially beneficial for new users learning the gnome-extensions tool, or for experienced users needing a refresher on particular functionalities.

Explanation:

• gnome-extensions: The main command for management of GNOME extensions.
• help: The subcommand used to display documentation or help information for another subcommand.
• list: The specific subcommand in question, for which help and detailed information are requested.

Example Output:

Usage:
  gnome-extensions list [OPTION…] 

Get a list of installed extensions.

Display version

Code:

gnome-extensions version

Motivation:

Knowing the version of the gnome-extensions tool can be essential for debugging purposes, compatibility checks, or support queries. This information is particularly important if users encounter issues or need to ensure that they are using the latest version or a version compatible with a particular GNOME Shell.

Explanation:

• gnome-extensions: The command for managing extensions within GNOME Shell.
• version: A subcommand requesting the current version of the gnome-extensions tool itself.

Example Output:

gnome-extensions 40.0

Conclusion

By using the gnome-extensions command with these examples, GNOME desktop users can efficiently manage extensions directly from the terminal. This functionality provides powerful control over how extensions are listed, configured, enabled, and removed, all of which streamline system management and tailor the desktop environment to better meet individual user preferences and requirements.
