ujust is a command-line utility included in Universal Blue-based operating systems (like Bazzite) that provides a series of scripts and configuration tweaks. These commands allow you to customize, fix, or enhance various aspects of your system. Each ujust command is designed to address a specific use case, such as enabling driver support, configuring system services, or adjusting performance settings.

Why Use ujust?

The ujust tool simplifies many advanced or repetitive tasks. Rather than manually editing system files or installing packages one by one, you can run a single ujust command that automatically applies the relevant changes or installs the necessary components. This approach is especially useful for new Bazzite users or those who want a streamlined method to tailor their system.

How to Use ujust

• Check Available Commands: Run ujust (with no arguments) to see a list of available subcommands and their short descriptions.
• Run a Specific Command: Use sudo ujust <command-name> to apply a fix, enable a driver, or configure your system.
• Follow Any Prompts: Some commands may ask for confirmation or additional details (e.g., a username for add-users-to-input-group).
• Reboot or Logout (if prompted): Certain changes may require a reboot or logout to take effect fully.
