Which command checks keyboard settings in a Linux environment?

The command that checks keyboard settings in a Linux environment is localectl. This utility is part of systemd and is used primarily to manage system locale and keyboard layout settings. When executed, localectl can provide information about the current keyboard layout being used, as well as allow users to change it if necessary. It can display both the system locale and the console and X11 keyboard layouts configured in the system, making it an effective tool for managing keyboard settings in a Linux environment.

Other commands related to keyboard settings have different uses. For example, kbdconfig is typically associated with configuring keyboard layouts in certain distributions but is not universally available or used across all Linux systems. xset is used primarily for X Window System settings, handling parameters such as screen brightness and mouse settings, rather than specifically checking keyboard settings. setxkbmap is a command used to set the keyboard layout for X sessions but does not provide a comprehensive report of current settings like localectl does. Thus, localectl stands out as the most effective and complete choice for checking keyboard settings.
