The "localectl list-x11-keymap-variants ${de}" command is used to display the available variants of the X11 keymap for the German language.

Here is a breakdown of the command:

• "localectl" is a command-line utility for controlling the system's locale and keyboard layout settings.
• "list-x11-keymap-variants" is the specific option used with localectl to list the available variants of the X11 keymap for a particular language.
• "${de}" is a placeholder representing the language code, in this case, "de" which stands for German. The "$" before the variable name indicates that the value will be provided at the time of executing the command.

By substituting "${de}" with the actual value "de", the command becomes: "localectl list-x11-keymap-variants de"

Executing this command will provide a list of available X11 keymap variants for the German language. These variants could include different keyboard layouts or modifications specific to certain regions or preferences.
